[0012] (Knowledge and other information that formed the basis of this disclosure) At the time the inventors conceived this disclosure, the technology of air conditioners was facing a demand for energy conservation. Therefore, in the industry, the high energy consumption of air conditioners was a challenge, and it was common practice to install fans alongside air conditioners to reduce their energy consumption and achieve energy savings. Fans such as circulators, when combined with air conditioners, can contribute to reducing energy consumption and eliminating heat buildup. Under these circumstances, the inventors discovered that these fans, compared to air conditioners, had a problem: users did not easily perceive the effects upon installation, making widespread adoption difficult. Furthermore, there was no disclosure of fan proposals or technologies for selecting air conditioner models that take fans into account, indicating room for improvement. The inventors arrived at the subject matter of this disclosure in order to solve these problems. This disclosure provides a fan installation support system, a fan installation support method, and a program that make it easier for users to experience the benefits of installing a fan.
[0013] The embodiments will be described in detail below with reference to the drawings. However, unnecessary details may be omitted. For example, detailed explanations of already well-known matters or redundant explanations of substantially identical configurations may be omitted. This is to avoid the following explanation becoming unnecessarily verbose and to facilitate understanding for those skilled in the art. The attached drawings and the following description are provided to enable those skilled in the art to fully understand this disclosure and are not intended to limit the subject matter described in the claims.
[0014] (Embodiment 1) Embodiment 1 will be described below with reference to the drawings.
[0015] [1-1. Structure] [1-1-1. Overall System Configuration] Figure 1 shows the configuration of the blower installation support system 1000. The blower installation support system 1000 is a system that supports the installation of air conditioning equipment 1 in a building BL. The blower installation support system 1000 includes a terminal device 2 and a server device 3, and provides equipment installation support services to assist in the installation of air conditioning equipment 1.
[0016] [1-1-1-1. Target Space] In detail, the fan installation support system 1000 assists in the selection of air conditioning equipment 1 to be installed in a space such as a room within the building building line (BL). The space to which the air conditioning equipment 1 is to be installed will be referred to as the target space S below. The target space S corresponds to any space such as a room, floor, or space within the building BL. Furthermore, the target space S may be a part of a large room, and is not limited to partitioned spaces.
[0017] The fan installation support system 1000 of this embodiment supports the installation of air conditioning equipment 1 in a target space S of a newly constructed building BL1, which is a building BL. The fan installation support system 1000 also supports the installation of air conditioning equipment 1 in a target space S of an existing building BL2, which is an existing building BL. In Figure 1, the newly constructed building BL1 is shown with a dotted line, and the existing building BL2 is shown with a solid line.
[0018] Examples of building BLs include houses, offices, warehouses, shops, factories, school buildings, and lodging facilities. In this embodiment, non-residential buildings such as commercial buildings are used as examples of building BLs. The fan introduction support system 1000 may also be configured to support the introduction of air conditioning equipment 1 to target spaces S installed in vehicles other than building BLs, such as aircraft and ships.
[0019] [1-1-1-2. Air Conditioning Equipment] The air conditioning equipment 1 that the blower installation support system 1000 supports may include an air conditioner and a blower.
[0020] In this specification, an air conditioner refers to a so-called air conditioning unit that provides heating, cooling, or dehumidification for a target space S. The air conditioner may be a separate type having an outdoor unit and an indoor unit, or it may be an integrated type. The indoor unit of the air conditioner may be any type of indoor unit, such as a four-way ceiling cassette type, a two-way ceiling cassette type, a one-way ceiling cassette type, a ceiling built-in type, a ceiling suspended type, a wall mounted type, a floor-standing type, a duct type, or a perimeter indoor unit. The indoor units of these air conditioners may be configured to measure and record the thermal environment of the room in terms of temperature and humidity over time, by including a temperature sensor, humidity sensor, or floor temperature sensor, etc. The outdoor units of these air conditioners may be configured to include a temperature sensor and a humidity sensor for measuring the temperature and humidity of the outdoors. Note that the aforementioned sensors may be installed in devices independent of the air conditioner. For example, the aforementioned sensors may be installed in a fan, ventilation device, remote control, or measuring instrument.
[0021] Furthermore, the term "blower" in this specification includes devices that stir the air in a target space S by generating airflow, thereby eliminating temperature unevenness and stagnant air in the target space S. Examples of this type of blower include circulators, transport fans, and ceiling fans. In addition, blowers may include devices that generate airflow for purposes other than air stirring, such as air curtains, perimeter fans, anemostats, and jet nozzles. Moreover, in this specification, a blower may include a nozzle (hereinafter referred to as a VZ nozzle) that is externally attached to an air conditioner and adjusts the direction of the hot or cold air blown out from the air conditioner. In other words, the blower in this specification is not limited to devices that can generate airflow on their own, but may also control airflow generated by other devices such as air conditioners.
[0022] Furthermore, the air conditioning equipment 1 that the fan introduction support system 1000 supports the introduction of may include a ventilation device that ventilates the target space S. The ventilation device may or may not have a total heat exchanger that exchanges heat between the air supplied from outdoors to indoors and the air exhausted from indoors to outdoors. In addition, the ventilation mode of the ventilation device may be any of Type 1 ventilation, Type 2 ventilation, or Type 3 ventilation.
[0023] The fan installation support system 1000 outputs at least one of the required time Δt or power consumption H, described later, for both an installation case in which the air conditioning equipment 1 to be installed in the target space S includes both an air conditioner and a fan, and a control case in which it includes an air conditioner but does not include a fan. By providing such outputs, the fan installation support system 1000 shows the difference with and without a fan, making it easier for users to understand the effects of installing a fan, thereby supporting the installation of air conditioning equipment 1 that includes a fan.
[0024] [1-1-1-3. Overview of Terminal Devices] Terminal device 2 is a PC (Personal Computer). In Figure 1, a laptop PC is shown as an example of terminal device 2, but terminal device 2 can be a desktop PC, a tablet PC, or a smartphone. Terminal device 2 is an example of a "computer".
[0025] Terminal device 2 is configured to be capable of calculating power consumption H or required time Δt. However, power consumption H or required time Δt may be calculated by any other server device, etc.
[0026] In detail, terminal device 2 can calculate power consumption H or required time Δt based on the simulation output data D2 for the target space S. Building information J11 and evaluation condition data D0 are used for the simulation for the target space S.
[0027] Furthermore, the terminal device 2 can calculate the power consumption H or the required time Δt based on the operating data D3 obtained by temporarily installing the air conditioning equipment 1 in the target space S. In this embodiment, the terminal device 2 receives the operating data D3 from the server device 3 via the network NW. The network NW may include the Internet, a telephone network, or other communication networks. The terminal device 2 may also read and obtain the operating data D3 stored on a portable storage medium or the like.
[0028] [1-1-1-4. Overview of Server Equipment] Server device 3 is a device that processes information using devices connected to the network NW as clients. In Figure 1, server device 3 is represented by a single block, but this does not mean that server device 3 is composed of a single device; server device 3 may be composed of multiple devices. The network NW may be implemented in any form such as the internet or an intranet, and server device 3 may be implemented in a form such as a cloud system, computer, or controller.
[0029] Server device 3 acquires operation data D3 from the control device that manages the air conditioning equipment 1 temporarily installed in the existing building BL2 at predetermined intervals (for example, every hour; data at 1-minute intervals is needed for detailed analysis of operating conditions), and ideally stores the acquired operation data D3 cumulatively for more than one year. The operation data D3 should ideally be available at 1-hour intervals for periods of about two weeks each in summer, winter, and the transitional season. Server device 3 stores the acquired operation data D3 for each target space S in the existing building BL2. Then, when requested by terminal device 2, server device 3 transmits the stored operation data D3 for each target space S in building BL2 to terminal device 2.
[0030] The operating data D3 is data indicating the operating status of the air conditioning system 1. Data indicating the operating status of the indoor unit includes the set temperature, indoor unit intake temperature, indoor unit outlet temperature, indoor unit airflow rate, operating time, and thermostat on / off. Data indicating the operating status of the outdoor unit includes the operating mode (cooling / heating), operating time, outside air temperature, compressor rotation speed, compressor intake pressure and intake temperature, compressor discharge pressure and discharge temperature, heat exchanger liquid pipe temperature, heat exchanger gas pipe temperature, heat exchanger outlet temperature, outdoor unit power consumption, various sensor values for the indoor and outdoor units as described above, the heat load processed by the indoor and outdoor units, and COP (operating efficiency). In addition, the operating data D3 may include detection values from various sensors such as thermosensors and floor temperature sensors installed in or independently on the indoor unit of the target space S. The air conditioning system 1 in this disclosure is mainly assumed to be a packaged air conditioner (VRF, GHP, PAC, etc.), but its application to central air conditioning is also envisioned.
[0031] [1-1-2. Detailed Configuration of Terminal Devices] Figure 2 shows the configuration of terminal device 2. Terminal device 2 comprises a control device 20, a communication unit 21, a display 22, and an input unit 23.
[0032] The communication unit 21 is equipped with communication hardware such as communication circuits that conform to a predetermined communication standard, and communicates with each device connected to the network NW.
[0033] The display 22 is composed of elements such as liquid crystal, LED (Light Emitting Diode), and OLED (Organic LED). The display 22 displays various information according to the control of the control device 20.
[0034] The input unit 23 is equipped with an interface circuit for connecting to devices such as operation switches, touch input panels, mice, and keyboards, and detects the input operations of the selector P1 and outputs the detection results to the processor 200.
[0035] The control device 20 is a device that controls various parts of the terminal device 2. The control device 20 includes a processor 200 such as a CPU (Central Processing Unit) or MPU (Micro Processor Unit), memory 220, and an interface circuit. Other devices and sensors of the terminal device 2 are connected to this interface circuit. Memory 220 corresponds to the "storage unit".
[0036] Memory 220 is a memory that stores programs and data. Memory 220 stores programs 221, simulation models 222, operational models UD, acoustic data 223, cost data 224, and data to be processed by the processor 200. Memory 220 has a non-volatile storage area. Memory 220 also has a volatile storage area and constitutes the work area of the processor 200. Memory 220 is composed of, for example, ROM (Read Only Memory) and RAM (Random Access Memory).
[0037] Program 221 is a program that supports the selection of air conditioning equipment 1 to be installed in the building line of construction (BL).
[0038] The simulation model 222 receives part or all of the building information J11 and the evaluation condition data D0 as input. The simulation model 222 also outputs at least one of the temperature distribution in the target space S or the power consumption of the air conditioning equipment 1 as output data D2. In this embodiment, the simulation model 222 is configured to output both the temperature distribution in the target space S and the power consumption of the air conditioning equipment 1 as output data D2.
[0039] Simulation model 222 includes at least one of an airflow analysis simulator and an energy simulator. The airflow analysis simulator is a simulator that analyzes the airflow and temperature in a target space S using a fluid analysis method based on computational fluid dynamics, etc., and can output the temperature distribution in the target space S. The energy simulator is a simulator that can output the power consumption of the air conditioning equipment 1 used in the target space S. Examples of energy simulators that can be used include EnergyPlus, TRNSYS, BEST, etc.
[0040] Simulation model 222 may include a building model, equipment model, and internal heat generation model, etc. The building model may include, as parameters, the thermal insulation performance and heat storage performance of the roof, exterior walls, windows, and floors that constitute the building BL or the target space S. The internal heat generation model may include parameters such as the amount of heat generated by the human body, equipment, and lighting fixtures in the target space S. Furthermore, the simulation conditions include defining and setting the work area within the target space S. When applied to an existing building BL2, a thermal camera is used to capture heat accumulations at the site, determining the positional relationship between the work area and the heat accumulation areas, and investigating the actual heat generation and surface temperature of the heat accumulations. These results are then reflected in the simulation model. When applied to a newly constructed building BL1, the amount of heat generated when people gather is estimated from the average number of people in the work area and the amount of heat generated per person. Examples of places where people gather include collection areas in warehouses where unloading work is performed. In the case of industrial equipment in a factory, the amount of heat generated per unit is determined from product catalogs, etc., and the amount of heat generated from the number of units installed is estimated and reflected in the simulation model. Examples of industrial equipment include tunnel ovens in food processing plants and hot water tanks in equipment manufacturing plants. However, areas around equipment where blowing air would stir up dust or fine particles, potentially harming people or processed foods, may be excluded from airflow and treated as heat reservoirs. Furthermore, as will be discussed later, directly blowing air onto industrial equipment that emits hot air or refrigeration equipment that emits cold air can cause the hot or cold air to dissipate into the surrounding area, potentially worsening the thermal environment. For this reason, industrial equipment and refrigeration equipment may also be excluded from airflow and treated as heat reservoirs. The equipment model may include an air conditioner model, a blower model, and a ventilation system model. The air conditioner model may include parameters such as operating modes (cooling, heating, dry, wind-shielding, circulation), airflow direction, set airflow, set temperature, COP (Coefficient of Performance), and rated power consumption. The blower model may include parameters such as airflow direction, set airflow, and rated power consumption. The ventilation system model may include parameters such as set ventilation volume, total heat exchanger capacity, and rated power consumption. In addition, various settings for the air conditioner, as described later, and simulation conditions such as airflow and airflow direction (up / down, left / right) for the blower are set. Furthermore, the worker's position in the work area and simulation parameters (e.g., airflow) are set to determine the values of SET* and PMV. Appropriate airflow and airflow direction are determined as initial settings based on the simulation results. Furthermore, the airflow and airflow direction may be manually adjusted on-site according to the worker's request.
[0041] Here, we will explain an example of how to calculate power consumption and heat load (cooling amount, heating amount) using an air conditioning model. The example air conditioner model is given parameters such as set temperature, set airflow, rated COP, and rated power consumption for each operating mode of the air conditioner.
[0042] The equipment model for an air conditioner is composed of the following equations (1) to (4). The symbol · represents the product. Q = F(ΔT1) (1) Q = ρ·Cp·Vol·ΔT² (2) Load factor = Q ÷ Rated capacity of the outdoor unit (3) Power consumption=Q÷COP (4) In equations (1) to (4), Q is the amount of cooling when the air conditioner is operating in cooling mode, and the amount of heating when the air conditioner is operating in heating mode. In equation (1), ΔT1 is the difference between the set temperature and the sensor value, which is the intake temperature of the indoor unit. If the indoor unit assumed in the air conditioner model can detect the floor surface temperature, ΔT1 may be the difference between the set temperature and the floor surface temperature. In equation (1), F() is obtained by associating Q with ΔT1 using a table lookup. The value of Q obtained in F() is associated with ΔT1 and is a table showing the relationship between ΔT1 and Q, created based on the minimum capacity, rating, maximum capacity, etc., of the selected model. Specifically, it is created by referring to the specifications, equipment configuration, control logic, etc., of the actual air conditioner equipment. In equation (2), ΔT2 represents the absolute value of the difference between the supply air temperature and the sensor value. That is, ΔT2 is the supply air temperature minus the sensor value during heating, and the sensor value minus the supply air temperature during cooling. In equation (2), ρ is the density of air, Cp is the specific heat of air, and Vol is the supply airflow rate. In the example model, Vol is a constant value corresponding to the set airflow rate, and ρ and Cp are also assumed to be constant values.
[0043] The process for the above air conditioner model involves performing calculations using equations (1) to (4), and once the calculation of equation (4) is complete, it returns to the calculation of equation (1). First, Q is calculated using equation (1).
[0044] Next, ΔT2 is calculated by substituting Q, obtained from equation (1), into equation (2).
[0045] Next, the Q calculated by equation (1) is substituted into the left side of equation (3) to obtain the load factor. Then, from the relationship diagram between the load factor and COP, the COP corresponding to the load factor calculated by equation (3) can be determined. The characteristics of the relationship diagram between load factor and COP are defined for each air conditioner model. The relationship diagram is determined by specifying the rated COP and rated power consumption of the air conditioner in the equipment model. Alternatively, the relationship diagram may be defined separately for cooling and heating. Furthermore, an equation may be constructed from the perspective of latent heat that takes humidity into account.
[0046] Then, the calculated COP and Q obtained by equation (1) are substituted into equation (4), and the left side of equation (4) is calculated as the power consumption corresponding to the current load factor. Other simulation conditions such as the operating mode (cooling, heating, dehumidification), set temperature, and set airflow are also provided as part of the air conditioner model.
[0047] In this example of an air conditioner model, the sensor value of the indoor unit's intake temperature is taken as input, and ΔT2 and power consumption are output.
[0048] Furthermore, it is possible to perform coupled analysis of an energy simulator, including the example air conditioner model, with airflow analysis. When performing a coupled analysis with airflow analysis, the sensor values used to calculate ΔT1 in equation (1) may be the intake temperature of the indoor unit or the floor surface temperature, extracted from the temperature distribution obtained by the airflow analysis.
[0049] The supply air temperature discharged from the indoor unit may be calculated using ΔT2 obtained from equation (2). Specifically, when the air conditioner is operating in cooling mode, the supply air temperature can be calculated by subtracting ΔT2 from the sensor value used to calculate ΔT1 in equation (1). When the air conditioner is operating in heating mode, the supply air temperature can be calculated by adding ΔT2 to the sensor value. Furthermore, the calculated supply air temperature can be used as a condition for simulation in airflow analysis, such as boundary conditions corresponding to the supply air temperature of the indoor unit.
[0050] In other words, in coupled analysis, sensor values for calculating ΔT1 in equation (1) are extracted from the temperature distribution obtained by airflow analysis, and the power consumption of the air conditioner and ΔT2 are obtained using equations (1) to (4) of the air conditioner model. Next, the supply air temperature of the indoor unit is calculated from ΔT2. Then, the calculated supply air temperature is given as simulation conditions such as boundary conditions corresponding to the supply air temperature of the indoor unit, and the airflow analysis is advanced for a predetermined time. Then, sensor values for calculating ΔT1 in equation (1) are extracted again from the temperature distribution obtained after advancing the airflow analysis for a predetermined time. Thus, in coupled analysis of energy simulators and airflow analyses, changes in the behavior of air conditioners in response to intake temperature can be reflected in both the airflow analysis and the energy simulator.
[0051] The following is an example of a table showing the relationship between ΔT1 and Q used in equation (1). The air conditioning load Q that the required air conditioner must handle includes heat ingress from walls, floors, and ceilings (heat transfer), radiant heat (solar radiation, long-wave radiation), and internal heat generation (people, lighting, equipment). Radiant heat, including solar radiation, can be included in heat transfer because it can be assumed that heat incident on a room is absorbed by one of the solid surfaces in the room. When measuring floor surface temperature with an indoor unit, an infrared array sensor installed on the indoor unit can measure not only the floor surface temperature but also the internal heat generation (heat generated by people and equipment in the room), and these can be reflected in the control of the air conditioner.
[0052] To simplify table design, there is a method to determine the air conditioning load Q that an air conditioner should handle using heat transfer. According to this method, the heat transfer load Q can be calculated using the formula Q = α·A·ΔT1. Here, α is the indoor convection heat transfer coefficient, which is either a function of wind speed or a general fixed value on the indoor side. A is the sum of the surface areas of the room (walls, floor, ceiling). A is defined from the standard room size assumed in the hardware capacity of the indoor unit (air conditioner specifications). A table showing the relationship between ΔT1 and Q from the heat transfer formula is created by varying the magnitude of ΔT1 and defined as an air conditioner model.
[0053] As described above, the simulation model 222 performs the simulation by including the building information J11 and evaluation condition data D0, which are given as inputs, as simulation conditions. The building information J11 may include specific values to be substituted for each parameter in the building model and the internal heat generation model. The evaluation condition data D0 may include specific values to be substituted for each parameter in the equipment model.
[0054] In detail, building information J11 includes information on the target space S and the building BL containing the target space S, specifically information on elements that are not affected by the installation and operation of the air conditioning equipment 1. Building information J11 may include information about the building BL itself that has the target space S. More specifically, building information J11 may include information such as the floor height, location, type of building materials, type of fixtures, and purpose of the building BL that has the target space S. Furthermore, building information J11 may include information about the target space S itself as a facility. Specifically, building information J11 may include the location of the target space S in building BL, the number of floors of the target space S (information indicating which floor it is in a building BL of a certain number of floors), the shape of the target space S, the floor area of the target space S, the ceiling height of the target space S, the number of windows in the target space S, the area of the windows in the target space S, the direction in which the windows are installed in the target space S, and the material of parts of building BL in the target space S (for example, windows, exterior walls, roof, etc.) (for example, thermal insulation rate, thickness, area, etc.). Furthermore, building information J11 may include information on people and lighting equipment in the target space S. More specifically, building information J11 may include information such as the occupancy ratio (the percentage of floor area occupied by people), occupancy density, human body heat generation, human body heat generation ratio, number of people, people's placement, and the time periods when people are present in the target space S. In addition, building information J11 may include information on the placement of lighting equipment and other equipment in the target space S, lighting heat generation, lighting heat generation ratio, equipment heat generation, equipment heat generation ratio, and operating time periods.
[0055] The evaluation condition data D0 contains information about the air conditioning equipment 1 in the target space S. The evaluation condition data D0 can be used as evaluation conditions to be given to the simulation model 222. In addition, the evaluation condition data D0 can be used as information to determine the arrangement, model, and operation of the air conditioning equipment 1 when the air conditioning equipment 1 is temporarily installed in the target space S and evaluated. In detail, the evaluation condition data D0 may include information such as the arrangement of each air conditioning equipment 1 in the target space S (location and orientation in the target space), type (any of air conditioners, blowers, and ventilation devices), model (specifications of air conditioning equipment 1 such as capacity, volume, annual energy efficiency, maximum airflow, maximum ventilation), operating mode (heating operation, cooling operation, dehumidification operation, fan operation, wind deflector operation mode, circulation operation mode, etc.), and operating intensity (set temperature, airflow, etc.).
[0056] The operational model UD is data that can provide simulation conditions for the simulation model 222. In this embodiment, the simulation model 222 may include the operational model UD as a simulation condition in addition to the building information J11 and evaluation condition data D0. For example, the simulation model 222 may use the operational model UD to determine simulation conditions for items where conditions such as parameters are not specified by, for example, the building information J11 and evaluation condition data D0. The operational model UD may be set during the operational planning of the building BL, set based on actual measurement examples of the building BL, or set based on building equipment design standards or prescribed standards such as WEBPRO.
[0057] Acoustic data 223 is data containing information about the noise power level of the air conditioning equipment 1. For example, acoustic data 223 may include noise power level values predetermined for each type, model, and airflow of air conditioning equipment 1, as listed in catalogs, etc. Alternatively, acoustic data 223 may include measured noise power levels measured with a sound level meter in the laboratory / at the delivery site, or calculated noise power levels based on prior acoustic simulations, for each type, model, and airflow of air conditioning equipment 1.
[0058] Cost data 224 is data containing information about the costs of the air conditioning equipment 1. For example, cost data 224 may include the purchase cost of the equipment for each type and model of air conditioning equipment 1. Also, cost data 224 may include the installation cost of the equipment for each type and model of air conditioning equipment 1. Furthermore, cost data 224 may include information on the total introduction cost, which is the sum of the purchase cost and installation cost of the equipment, for each type and model of air conditioning equipment 1. In addition, cost data 224 may include information about the running costs of air conditioning equipment 1. Information on running costs may include, for example, electricity charges per unit of power consumption, and costs for inspection, maintenance, parts replacement, etc., which are set for each type and model of air conditioning equipment 1.
[0059] The processor 200 functions as a reception unit 201, acquisition unit 202, calculation unit 203, display unit 204, heat accumulation location identification unit 205, amortization period calculation unit 206, and model selection unit 207 by reading and executing the program 221 stored in the memory 220. The display unit 204 is an example of an "output unit," a "candidate presentation unit," and an "acoustic presentation unit."
[0060] [1-1-2-1. Reception Department] The reception unit 201 receives operations from the selector P1 via the input unit 23.
[0061] [1-1-2-2. Acquisition section] The acquisition unit 202 acquires information on heat accumulation locations in the target space S of building BL. The information on heat accumulation locations acquired by the acquisition unit 202 may be information entered by the selector P1 through the input unit 23, which is received by the reception unit 201. Alternatively, the acquisition unit 202 may acquire information on heat accumulation locations identified from the target space S by the heat accumulation location identification unit 205, which will be described later.
[0062] A heat accumulation point is a location in the target space S where heat is likely to accumulate. Whether or not a location is prone to heat accumulation is determined, for example, by a relative comparison with other locations in the target space S. For example, any location in the target space S where heat accumulation is more likely to occur than other locations is a heat accumulation point. Specifically, heat accumulation points may be locations in the target space S that are prone to becoming hotter than other locations in the target space S, such as near people or heat-generating elements (for example, human heat sources include conference rooms in offices and collection areas in warehouses, and heat-generating elements include industrial equipment in factories), or locations affected by sunlight. Also, heat accumulation points may be locations in the target space S that are prone to becoming colder than other locations in the target space S, such as near refrigeration equipment in supermarkets and convenience stores, or near windows in winter. Further specific examples of heat accumulation points will be discussed later.
[0063] The occurrence of heat accumulation in a certain location in the target space S means that the temperature at that location in the target space S is at least a predetermined temperature difference dT away from the optimal temperature Ts in the target space S, either in the direction of being hotter or colder. The optimal temperature Ts in the target space S is the desirable temperature according to the purpose of use of the target space S. For example, if the target space S is a space where people are present, such as a conference room or office, the optimal temperature Ts may be a temperature that is comfortable for people. Specifically, if the heat accumulation is caused by people, as described later, the optimal temperature may be defined by values defined by SET* or PMV, and the wind speed and temperature around people when using a fan may be calculated, and the fan may be controlled using values such as SET* or PMV as indicators. Also, for example, if the target space S is a space intended for heating or cooling equipment or items, such as a server room, the optimal temperature Ts may be a temperature at which the equipment or items can be properly operated or stored. Also, for example, the set temperature of the air conditioner in the target space S may be considered as the optimal temperature Ts in the target space.
[0064] [1-1-2-3. Calculation Section] The calculation unit 203 calculates at least one of the following for a heat accumulation point in the target space S: the required time Δt, which is the time it takes for the temperature at the start of the evaluation to reach a reference temperature T9, or the power consumption H. In this embodiment, the calculation unit 203 calculates both the required time Δt and the power consumption H. The power consumption H here is the power consumption of the air conditioning equipment 1 in the target space S during the required time Δt for the temperature at the heat accumulation point to reach the reference temperature T9 from the start temperature T0. The reference temperature T9 is set to a temperature close to the optimal temperature Ts in the target space S, compared to the start temperature T0 of the heat accumulation point. That is, the reference temperature T9 can be a temperature between the optimal temperature Ts and the start temperature T0. Alternatively, the reference temperature T9 can be the same value as the optimal temperature Ts or a value around the optimal temperature Ts.
[0065] In other words, the calculation unit 203 calculates the time Δt and power consumption H required for the temperature of the heat accumulation point in the target space S to reach a reference temperature T9 close to the appropriate temperature Ts, from an initial temperature T0 far from the appropriate temperature Ts. The reference temperature T9 corresponds to an example of a "predetermined temperature" in this disclosure.
[0066] The calculation unit 203 may calculate the required time Δt and power consumption H from the results of a simulation using the simulation model 222. Alternatively, the calculation unit 203 may calculate the required time Δt and power consumption H using operating data D3 obtained by temporarily installing the air conditioning equipment 1 in the target space S.
[0067] The optimal temperature Ts, starting temperature T0, and reference temperature T9 referred to herein are not limited to physical quantities of temperature such as Celsius temperature, Kelvin temperature, or Fahrenheit temperature. For example, thermal indices calculated using temperature as a physical quantity and other environmental conditions such as humidity may be used as the optimal temperature Ts, starting temperature T0, and reference temperature T9. For example, WBGT (Wet Bulb Globe Temperature), discomfort index, PMV (Predicted Mean Mobility), SET* (Standard Effective Temperature), etc., may be used as the optimal temperature Ts, starting temperature T0, and reference temperature T9.
[0068] In detail, in this embodiment, the calculation unit 203 calculates the required time Δt and power consumption H for both an introduction case in which a blower is introduced as an air conditioning system 1 for the target space S, and a control case in which a blower is not introduced for the target space S.
[0069] In this embodiment, the calculation unit 203 calculates the sound power level of the operating noise generated by the operation of the air conditioning equipment 1 installed in the target space S. The calculation unit 203 acquires information such as the airflow rate of the air conditioning equipment 1 from the results of a simulation using the simulation model 222, or from the operation data D3 obtained by temporarily installing the air conditioning equipment 1 in the target space S. Then, the calculation unit 203 uses the acquired information such as the airflow rate and the sound data 223 stored in the memory 220 to determine the sound power level of the operating noise generated by the operation of the air conditioning equipment 1. Specifically, the sound data 223 defines the relationship between the airflow rate of the blower and the noise generated using information on the blower's specifications, such as those described in the product catalog. The noise value increases as the airflow rate increases. The noise value (for example, a decibel value) is determined from the airflow rate using this specification information.
[0070] [1-1-2-4.Display section] The display unit 204 controls the display 22 and causes the display 22 to display various screens.
[0071] [1-1-2-5. Identifying areas where heat accumulates] The heat accumulation location identification unit 205 identifies heat accumulation locations in the target space S that are prone to heat accumulation, based on information about the target space S.
[0072] The heat accumulation location identification unit 205 may identify heat accumulation locations using the results of a simulation using the simulation model 222 as information about the target space S. In this case, for example, the heat accumulation location identification unit 205 may use the temperature distribution of the target space S obtained by the airflow analysis simulator to identify locations in the target space S that are more likely to have temperatures farther from the optimal temperature Ts than other locations in the target space S as heat accumulation locations.
[0073] Furthermore, the heat accumulation location identification unit 205 may use operating data D3 obtained by temporarily installing the air conditioning equipment 1 in the target space S as information about the target space S. In this case, the heat accumulation location identification unit 205 may identify heat accumulation locations from the operating data D3, for example, from the measurement results by a thermosensor. The thermosensor may be provided in the temporarily installed air conditioner, etc., or it may be installed in the target space S as a standalone unit when the air conditioning equipment 1 is temporarily installed. In this case, for example, the heat accumulation location identification unit 205 may identify as a heat accumulation location a location in the target space S where the temperature is more likely to be farther from the optimal temperature Ts than other locations in the target space S, based on the measurement results of the thermosensor. Alternatively, the heat accumulation location identification unit 205 may place multiple temperature sensors in the target space S and quantitatively identify heat accumulation locations based on the detected values of the temperature sensors.
[0074] Furthermore, the heat accumulation location identification unit 205 may identify heat accumulation locations based on the building information J11. In this case, for example, the heat accumulation location identification unit 205 may identify heat accumulation locations in areas where people are densely packed in the target space S, areas where warm or cool air from air conditioners is difficult to reach due to obstacles blocking the air or distance from the air conditioner, areas where the amount of sunlight from windows is large, or areas where there is strong cold air from windows.
[0075] [1-1-2-6. Depreciation Period Calculation Section] The depreciation period calculation unit 206 calculates the depreciation period for the blower to be introduced into the target space S. The depreciation period calculation unit 206 uses the introduction cost and electricity charges for the blower in the introduction case obtained from the cost data 224, and the power consumption H for the control case and the introduction case calculated by the calculation unit 203, to calculate the depreciation period for the blower in the introduction case.
[0076] For example, the amortization period calculation unit 206 may calculate the amortization period L as shown in the following equation (5), where C is the cost of introducing the blower in the introduction case, H1 is the amount of electricity consumed in the introduction case, H2 is the amount of electricity consumed in the control case, c0 is the electricity rate per unit of energy, and I is the average interval between heat accumulations at heat accumulation points in the target space S (the units are, for example, years or days). However, the average interval I is the average period from when a heat accumulation occurs at a heat accumulation point until the next heat accumulation occurs (the units are, for example, days or hours). L = I·C / {(H2-H1)·c0} (5)
[0077] Furthermore, if the cost of installing the air conditioner in the installation case is lower than the cost of installing the air conditioner in the control case, the difference ΔC between the installation costs of the air conditioner in the installation case and the control case may be subtracted from the cost of installing the blower C in equation (5). In other words, the amortization period calculation unit 206 may calculate the amortization period L as shown in the following equation (6). L=I·(C-ΔC) / {(H2-H1)·c0} (6)
[0078] [1-1-2-7. Model Selection Section] The model selection unit 207 selects the model of the air conditioning equipment 1 using the building information J11 and the layout information of the air conditioning equipment 1 in the target space S.
[0079] Specifically, the model selection unit 207 estimates the wind speed near heat accumulation points based on the distance between the person and the fan in the target space S, and the spread of the airflow from the fan's outlet, and selects a fan. Heat accumulation points considered here include, for example, the location of a person. Regarding the spread of the airflow from the fan's outlet, information such as that found in the fan's catalog may be used. In this case, the memory 220 may store information about the spread of the airflow from the fan's outlet. Alternatively, the model selection unit 207 may model the target space S and use airflow analysis to confirm whether the necessary airflow reaches the vicinity of the person, and then select a fan. The model selection unit 207 may also select an air conditioner in the same manner as a fan.
[0080] Comparing the target case with the implementation case, the air conditioning equipment 1 installed in the target space S in the implementation case includes a blower, and an improvement in the effect of mitigating and eliminating heat buildup by the blower can be expected. In other words, it is likely that the air conditioner in the implementation case does not need to have the same capacity as the air conditioner in the control case in most cases. Generally, the larger the capacity of an air conditioner, the higher the installation cost and running cost, so it is desirable to install an air conditioner with a capacity that is necessary and sufficient for each application.
[0081] Therefore, the model selection unit 207 selects the air conditioning equipment 1 such that the capacity of the air conditioner in the installation case is less than or equal to the capacity of the air conditioner in the control case. Furthermore, if multiple air conditioners are installed in the installation case or control case, the model selection unit 207 selects the air conditioning equipment 1 such that the total capacity of the air conditioners in the installation case is less than or equal to the total capacity of the air conditioners in the control case. In this embodiment, the model selection unit 207 selects the air conditioning equipment 1 such that the capacity of the air conditioner in the installation case is smaller than the capacity of the air conditioner in the control case. Note that the capacity of the air conditioner referred to here is, for example, the maximum capacity of the air conditioner during cooling or heating operation.
[0082] [1-2. Operation] The operation of the blower installation support system 1000, configured as described above, will be explained below.
[0083] [1-2-1. Overall flow of equipment installation support services] First, we will explain the overall flow of the equipment installation support service provided using the blower installation support system 1000. Figure 3 is a diagram illustrating the general flow of the equipment installation support service provided using the blower installation support system 1000. The equipment installation support service shown in Figure 3 begins when the selection requester P2 requests the selection of air conditioning equipment 1 from the selector P1.
[0084] After a request is made to select air conditioning equipment 1, the equipment installation support service first proceeds to information acquisition phase S1. Information acquisition phase S1 is the phase in which the fan installation support system 1000 acquires information about the target space S for which air conditioning equipment 1 is to be selected.
[0085] Following the information acquisition phase S1, the equipment installation support service moves to the calculation condition determination phase S2. The calculation condition determination phase S2 is the phase in which the calculation unit 203 determines the evaluation conditions for calculating the power consumption H and the required time Δt for both the installation case and the control case.
[0086] Following the calculation condition determination phase S2, the equipment installation support service moves on to the calculation phase S3. In the calculation phase S3, the calculation unit 203 calculates the power consumption H and the required time Δt for both the installation case and the control case, based on the evaluation conditions determined in the calculation condition determination phase S2.
[0087] Following the calculation phase S3, the equipment installation support service moves to the output phase S4. The output phase S4 is the phase in which the power consumption H and required time Δt for both the installation case and the control case, which were calculated in the calculation phase S3, are output.
[0088] In output phase S4, the display unit 204 outputs the power consumption H and required time Δt in a manner that allows for comparison between the case in which a blower is introduced and the control case in which a blower is not introduced. Therefore, the selection requester P2 can understand the effect on power consumption H and required time Δt by introducing a blower to the target space S.
[0089] Upon completion of output phase S4, the equipment installation support service provided using the blower installation support system 1000 is terminated.
[0090] [1-2-2. Details of each phase] Next, we will explain the details of each phase S1 to S4 in the equipment installation support service in order.
[0091] [1-2-2-1. Information Acquisition Phase] In the information acquisition phase S1, the acquisition unit 202 acquires building information J11. The building information J11 acquired by the acquisition unit 202 is stored in the memory 220.
[0092] In this embodiment, the acquisition unit 202 acquires building information J11 from input operations received by the reception unit 201 via the input unit 23. In this case, the display unit 204 displays a screen on the display 22 that accepts input for some or all of the information items included in the building information J11. In this embodiment, the building information J11 acquired by the acquisition unit 202 includes at least information regarding the thermal insulation performance of the building BL. Information regarding the thermal insulation performance of the building BL may include, for example, information such as the type of building materials constituting the building BL, the thermal insulation ratio of the building materials, and the thickness of the building materials.
[0093] The acquisition unit 202 may also acquire building information J11 from any server device or the like connected via a network NW using the communication unit 21. Alternatively, the acquisition unit 202 may acquire building information J11 by reading it from a portable storage medium or the like.
[0094] [1-2-2-2. Phase for determining calculation conditions] In the calculation condition determination phase S2, the acquisition unit 202 acquires evaluation condition data D0. The evaluation condition data D0 includes information on the air conditioning equipment 1 installed in the target space S during the simulation conditions of the simulation model 222 or evaluation by temporary installation. Since it is desirable to reflect the intentions of the selection requester P2 regarding the arrangement of the air conditioning equipment 1 in the target space S, the acquisition unit 202 acquires evaluation condition data D0 that reflects the requests of the selection requester P2 in the calculation condition determination phase S2.
[0095] However, the selection requester P2 may not have knowledge regarding the placement and selection of the air conditioning equipment 1. Therefore, in the calculation condition determination phase S2, the terminal device 2 performs actions to facilitate the placement and selection of the air conditioning equipment 1 for the selection requester P2.
[0096] Figure 4 is a flowchart showing an overview of the operation of terminal device 2 in calculation condition determination phase S2, illustrating the operation of terminal device 2 until it acquires evaluation condition data D0. The operation of calculation condition determination phase S2 in Figure 4 is triggered by the completion of information acquisition phase S1, or by an input operation instructing input unit 23 to proceed to calculation condition determination phase S2.
[0097] At the beginning of the calculation condition determination phase S2, in step S21, the display unit 23 displays the layout candidate screen G01 using the display 22.
[0098] Figure 5 shows an example of the placement candidate screen G01. The placement candidate screen G01 shown in Figure 5 corresponds to an installation case. The placement candidate screen G01 is a screen that shows candidate placements of air conditioners and blowers in the target space S. The placement candidate screen G01 includes multiple placement candidate diagrams I1. In the example in Figure 5, the placement candidate screen G01 includes six types of placement candidate diagrams I1A to I1F. The placement candidate screen G01 also includes placement description text J1, which is text that explains each placement candidate diagram I1. In the example in Figure 5, the placement candidate screen G01 has placement description texts J1A to J1F that explain each of the six types of placement candidate diagrams I1A to I1F, and these are placed in the information of the corresponding placement candidate diagrams I1A to I1F. In each of the placement candidate diagrams I1A to I1F, white arrows and clouds represent the airflow and heat accumulation of warm air, and black arrows and clouds represent the airflow and heat accumulation of cold air.
[0099] Layout candidate diagram I1 is a schematic diagram showing candidate arrangements of air conditioners and blowers in the target space S, as candidate evaluation conditions for the implementation case.
[0100] In the example in Figure 5, the layout candidate screen G01 includes layout candidate diagram I1A, which shows an example of a layout where the air conditioner and the fan are placed opposite each other, as layout candidate diagram I1 for heating. The layout explanation text J1A describing layout candidate diagram I1A also includes the words "air conditioner and fan placed opposite each other." According to the opposing layout shown in layout candidate diagram I1A, where the air blown from the air conditioner and the air blown from the fan collide, a circulating airflow is generated in the target space S by the colliding air, making it easier to equalize the temperature distribution in the target space S.
[0101] The layout candidate screen G01 includes layout candidate diagram I1B, which shows an example of a layout where the fan is placed above the air conditioner during heating. The layout explanation text J1B, which describes layout candidate diagram I1B, also includes the phrase "place the fan above the air conditioner." According to the layout shown in layout candidate diagram I1B, where the fan is placed above the air conditioner, the airflow from the air conditioner is assisted by the air blown out by the fan, and a circulating airflow is generated in the target space S, making it easier to equalize the temperature distribution in the target space S.
[0102] The layout candidate screen G01 includes layout candidate diagram I1C, which shows an example of a layout when the blower fan is controlled to swing during heating. The layout explanation text J1C, which describes layout candidate diagram I1C, also includes the phrase "control the blower to swing." According to the layout shown in layout candidate diagram I1C, which assumes that the blower is controlled to swing, the air blown from the air conditioner is transported to each part of the target space S by the air blown from the blower, making it easier to equalize the temperature distribution of the target space S.
[0103] The layout candidate screen G01 includes layout candidate diagram I1D, which shows an example of a layout where the air conditioner and blower are placed in a high-ceiling configuration to generate a downward airflow during cooling. The layout explanation text J1D, which describes layout candidate diagram I1D, also includes the phrase "downward airflow in a high-ceiling configuration." According to the layout shown in layout candidate diagram I1D, which generates a downward airflow using a blower and air conditioner, the temperature distribution can be more easily made uniform by stirring the air in the target space S vertically with the air blown out by the air conditioner and blower.
[0104] The layout candidate screen G01 includes layout candidate diagram I1E, which shows an example of a layout when the fans are arranged in a circulating configuration during cooling. The layout explanation text J1E, which describes layout candidate diagram I1E, includes the words "circulating configuration of fans" and the words "(from the ceiling)" which indicate that layout candidate diagram I1E shows the configuration as viewed from the ceiling. According to the circulating configuration shown in layout candidate diagram I1E, in which multiple fans are arranged so that the air blown out by the fans circulates, the temperature distribution of the target space S can be more easily made uniform by circulating the air blown out by the fans.
[0105] The layout candidate screen G01 includes layout candidate diagram I1F, which shows an example of a layout where the fan is positioned perpendicular to the air conditioner during cooling. The layout explanation text J1F, which describes layout candidate diagram I1F, also includes the phrase "positioned perpendicular to the air conditioner." According to the layout shown in layout candidate diagram I1F, where the air blown by the fan intersects perpendicularly with the air blown by the air conditioner, the airflow from the air conditioner is assisted by the air blown by the fan, and a circulating airflow is generated in the target space S, making it easier to equalize the temperature distribution in the target space S.
[0106] In this embodiment, the display unit 204 is configured to display the layout candidate diagram I1 according to the building information J11 acquired by the acquisition unit 202 in the information acquisition phase S1. Specifically, each layout candidate diagram I1 is labeled with information about the target space S in which the layout of the air conditioning equipment 1 shown in the layout candidate diagram I1 is likely to be effective.
[0107] Examples of labels assigned to each candidate layout diagram I1 include "high ceiling" (e.g., ceiling height is above a specified height), "other than high ceiling" (e.g., ceiling height is below a specified height), "large space" (e.g., floor area is above a specified area), or "other than large space" (e.g., floor area is below a specified area). In addition, each candidate layout diagram I1 may be assigned a label indicating the use of the target space S, such as "office," "store," "logistics warehouse," or "factory."
[0108] For example, the layout candidate diagram I1B, which shows an example of an arrangement where the blower is placed above the air conditioner, and the layout candidate diagram I1D, which shows an example of an arrangement where the air conditioner and blower are placed in a high ceiling to generate a downward airflow, are labeled "high ceiling". In addition, the layout candidate diagram I1E, which shows an example of an arrangement where the blower is in a circulating configuration, is labeled "large space".
[0109] In step S21, the display unit 204 refers to the building information J11 acquired by the acquisition unit 202 in the information acquisition phase S1, and if the target space S meets the conditions of the label assigned to the placement candidate diagram I1, it displays that placement candidate diagram I1 with priority over other placement candidate diagrams I1. For example, the display unit 204 may display only the placement candidate diagrams I1 that have labels that match the information contained in the building information J11 on the placement candidate screen G01. Alternatively, the display unit 204 may highlight the placement candidate diagrams I1 that have labels that match the information contained in the building information J11 on the placement candidate screen G01 by placing them higher, displaying them larger, adding a border, or marking them, so that they stand out more than other placement candidate diagrams I1.
[0110] By presenting the layout candidate screen G01, the selection requester P2 can learn about the main possible layout patterns for the air conditioning equipment 1 in the target space S. Therefore, it is easier to reflect the selection requester P2's intentions, for example, by selecting layout candidate diagram I1 from the layout candidate screen G01.
[0111] In step S21, the display unit 204 may display the layout candidate screen G01 corresponding to the control case, similar to the introduction case. In this case, each layout candidate diagram I1 will show an example of the layout of the air conditioning equipment 1 without the blower. Alternatively, in step S21, the display unit 204 may not display the layout candidate screen G01 corresponding to the control case. In this case, the layout of the air conditioning equipment 1 in the control case will be determined in the next step S22, including the general layout of the air conditioning equipment 1 as shown in the layout candidate diagram I1.
[0112] Next, in step S22, the acquisition unit 202 acquires information about the detailed arrangement of the air conditioning equipment 1 in the target space S. The detailed arrangement of the air conditioning equipment 1 acquired by the acquisition unit 202 in step S22 constitutes part of the evaluation condition data D0. The information about the detailed arrangement of the air conditioning equipment 1 in the target space S includes, for example, information such as the installation position and orientation of each air conditioner or blower.
[0113] In this embodiment, in step S22, the acquisition unit 202 acquires information about the detailed arrangement of the air conditioning equipment 1 in the target space S, which has been received by the reception unit 201 via the input unit 23. At this time, the display unit 204 may, for example, display a screen on the display 22 for receiving input about the detailed arrangement of the air conditioning equipment 1 from the input unit 23. The acquisition unit 202 may also acquire information about the detailed arrangement of the air conditioning equipment 1 in the target space S from any server device or the like via the communication unit 21.
[0114] In step S22, the acquisition unit 202 acquires, for example, the arrangement of the air conditioning equipment 1 in the target space S planned by the selector P1. It is desirable that the arrangement of the air conditioning equipment 1 in the target space S planned by the selector P1 reflects the intentions of the selection requester P2. In this embodiment, the selection requester P2 can communicate their intentions to the selector P1 simply by specifying the arrangement candidate diagram I1 corresponding to the desired arrangement from the arrangement candidate screen G01 displayed in step S21.
[0115] In step S23, the acquisition unit 202 acquires information on the model of the air conditioning equipment 1 in the target space S. The information on the model of the air conditioning equipment 1 acquired by the acquisition unit 202 in step S23 constitutes a part of the evaluation condition data D0.
[0116] In step S23, the acquisition unit 202 may, for example, acquire information about the model of the air conditioning equipment 1 selected by the model selection unit 207. At this time, the model selection unit 207 selects the model of the air conditioning equipment 1 using the building information J11 and the detailed arrangement information of the air conditioning equipment 1 in the target space S obtained in step S22.
[0117] Furthermore, in step S23, the acquisition unit 202 may acquire, for example, information about the model of the air conditioning equipment 1 selected by the selector P1. Based on the building information J11 and the detailed arrangement information of the air conditioning equipment 1 in the target space S, the selector P1 may read the wind speed at the locations where people are located in the target space S from the wind speed distribution described in catalogs of air conditioners or blowers, etc., and select an air conditioner or blower that can obtain the required wind speed. Specifically, the selector P1 may calculate the wind speed and air volume using equations (9) and (10) for calculating the wind speed and temperature around people, as shown in use cases 2 and 3 described later, and then estimate the effect using the SET* and PMV indices to select the air conditioner or blower. Also, similar to the model selection unit 207, the selector P1 selects the models of air conditioners and blowers such that the capacity of the air conditioner in the introduction case is smaller than the capacity of the air conditioner in the control case. In this case, the acquisition unit 202 may acquire information about the model of the air conditioning equipment 1 that the reception unit 201 has received via the input unit 23, or it may acquire information about the model of the air conditioning equipment 1 from any server device or the like via the communication unit 21.
[0118] Next, in step S24, the acquisition unit 202 acquires information on the operation method of the air conditioning equipment 1. The information on the operation method of the air conditioning equipment 1 acquired by the acquisition unit 202 in step S24 constitutes a part of the evaluation condition data D0.
[0119] Information regarding the operation method of the air conditioning equipment 1 may include, for example, the operating mode, set temperature, airflow rate, and airflow direction of the air conditioner, and the airflow rate and airflow direction of the blower. Furthermore, information regarding the operation method of the air conditioning equipment 1 may also include information regarding the conditions under which the operation method is applied. For example, conditions under which the operation method is applied include time-dependent conditions such as a specific time period, conditions depending on the state of the target space S such as the temperature or humidity reaching a specific standard value, or conditions depending on the number of people in the target space S, such as entry and exit.
[0120] In step S24, the acquisition unit 202 may acquire information on the operation method of the air conditioning equipment 1 that the reception unit 201 has received via the input unit 23. The display unit 204 may also, for example, display a screen on the display 22 for receiving input on the operation method of the air conditioning equipment 1 via the input unit 23. The acquisition unit 202 may also acquire information on the operation method of the air conditioning equipment 1 from any server device or the like via the communication unit 21.
[0121] For example, the acquisition unit 202 is configured to acquire whether or not the air conditioners in the introduction case and the control case perform circulation operation as an operating method for the air conditioning equipment 1. Circulation operation is an operation in which the air conditioner periodically moves the direction of the flap provided at the air outlet between a horizontal direction approximately parallel to the ceiling and a vertical direction approximately perpendicular to the floor. Circulation operation can help eliminate temperature unevenness in the room, especially at the start-up timing of the air conditioner. For example, if the air conditioner performs circulation operation in the introduction case, using it in conjunction with airflow from a blower can further accelerate the elimination of temperature unevenness in the target space S. In this case, by having the air conditioner perform circulation operation in the control case, the effect of airflow from the blower becomes easier to understand. Furthermore, for example, by having the air conditioner perform a circulation operation in the control case, and not having the air conditioner perform a circulation operation in the implementation case, and instead having the fan blow air, it becomes easier to compare the airflow from the fan with the circulation operation of the air conditioner.
[0122] In step S24, the acquisition unit 202 automatically determines a portion of the information regarding the operation method of the air conditioning equipment 1 to be adopted as part of the evaluation condition data D0, based on the building information J11, etc. The operation method automatically adopted by the acquisition unit 202 at this time is an operation method that allows for efficient operation of the blower in accordance with the building information J11, etc. Note that these operation methods may not be automatically adopted by the acquisition unit 202, but may be set by input from the selector P1 to the input unit 23, etc.
[0123] For example, the acquisition unit 202 refers to the building information J11 and changes the airflow rate of the blower in the introduction case according to the thermal insulation performance of the building BL having the target space S. More specifically, the acquisition unit 202 refers to the building information J11 and, if the thermal insulation performance of building BL is below a predetermined thermal insulation performance, increases the airflow rate of the blower in the introduction case in the evaluation condition data D0 compared to when the thermal insulation performance is not below the predetermined thermal insulation performance. When the thermal insulation performance of building BL is low, the target space S is more susceptible to the effects of heat from the outside, so if the airflow rate of the blower is set low to suppress noise, the required time Δt becomes relatively longer. Conversely, by setting the airflow rate of the blower high, the required time Δt can be relatively shortened.
[0124] Furthermore, the acquisition unit 202 refers to the building information J11 and automatically adopts the operation method for the air conditioning equipment 1 in the introduction case as the operation method for the air conditioning equipment 1 in the evaluation condition data D0, which is to operate the fan when the time of heat accumulation is less than or equal to a predetermined time, or when the frequency of heat accumulation is less than or equal to a predetermined frequency. In this case, the acquisition unit 202 automatically adopts the operation method for the air conditioning equipment 1 in the control case as the operation method for the air conditioning equipment 1 in the evaluation condition data D0, which is to operate the air conditioner. With such an operation method, in the introduction case, heat accumulation can be easily eliminated by using a fan with low power consumption. The acquisition unit 202 may also refer to the operation plan from the building information J11, such as the expected number of people in the target space S, the expected rate of meetings, and the expected operating period of heat-generating equipment.
[0125] Furthermore, the acquisition unit 202 refers to the evaluation condition data D0 and determines whether or not multiple outdoor units are installed outside the target space S. For example, the target space S may have multiple indoor units arranged as air conditioners, and each indoor unit may be connected one-to-one with multiple outdoor units. This configuration is common for packaged air conditioners (PACs) used in stores and small offices. Therefore, by providing information on such a configuration in advance as evaluation condition data D0, the acquisition unit 202 can determine whether or not the air conditioner is composed of multiple outdoor units at the time of equipment design. If the acquisition unit 202 determines that multiple outdoor units are installed outside the target space S, it automatically adopts an operation method as the evaluation condition data D0 for the introduction case, which is to equalize the load among the multiple outdoor units by using a fan to eliminate temperature unevenness in the target space S when the difference in load ratios between the multiple outdoor units is greater than or equal to a predetermined value. For example, the load ratio of the outdoor units may be given as the ratio of the current value of the outdoor unit to the rated current value of the outdoor unit. This operating method makes it easier to reduce the required time Δt and power consumption H by eliminating load imbalances between outdoor units using a fan. The load factor can be calculated, for example, by equation (3). Here, we focused on the outdoor unit, but when there are multiple indoor units, the load factor between the indoor units can be equalized using a fan. The load factor of an indoor unit can be estimated, for example, by the difference between the set temperature and the intake temperature of each indoor unit. In this case, a large difference between the set temperature and the intake temperature of each indoor unit results in a large load factor, and a small difference results in a small load factor. In this case, it can also be applied to configurations such as GHP and VRF, where multiple indoor units are housed in a single air conditioner.
[0126] Furthermore, the acquisition unit 202 refers to the evaluation condition data D0 and determines whether or not a ventilation device is installed in the target space S. If a ventilation device is installed in the target space S, the acquisition unit 202 automatically adopts an operation method as the evaluation condition data D0 for the introduction case, in which, when outside air cooling operation by the ventilation device is possible, the air conditioner is stopped and outside air cooling operation is performed, and the blower is operated during outside air cooling operation. With this operation method, for example, when the outside temperature is lower than the temperature of the target space S, such as in the early morning in summer, the outside air taken into the target space S by the ventilation device is more easily circulated in the target space S by the blower, making it easier to shorten the required time Δt.
[0127] The display unit 204 may also be configured to display the above-mentioned efficient operating methods as candidates for operating methods using the display 22. In this case, the acquisition unit 202 may be configured to receive an input operation via the input unit 23 to select a candidate for operating method displayed on the display 22, and to adopt the selected candidate for operating method as part of the evaluation condition data D0.
[0128] Upon completion of step S24, the calculation condition determination phase S2 is terminated.
[0129] [1-2-2-3. Calculation Phase] Next, in calculation phase S3, the calculation unit 203 calculates at least one of the required time Δt or the amount of power consumed H. Figure 6 is a flowchart showing an overview of the operation of the terminal device 2 in calculation phase S3, illustrating the operation when calculating at least one of the required time Δt or the amount of power consumed H.
[0130] At the beginning of the calculation phase S3, in step S31, the reception unit 201 receives an input operation via the input unit 23 to select whether to use output data D2 obtained by simulation or operating data D3 obtained by temporary installation of the actual equipment for calculating the required time Δt and power consumption H. In this case, in step S31, the display unit 204 may use the display 22 to display a screen allowing the user to select either simulation or temporary installation of the actual equipment. Alternatively, the required time Δt or power consumption H may be calculated using operating data D3 obtained from permanently installed equipment instead of temporary installation. In the case of permanently installed equipment, the operational effects can be clarified through analysis of the equipment's operating data D3, etc., which can be used as reference information for equipment users when updating equipment, and as information for equipment sellers to promote equipment sales.
[0131] In step S31, if the reception unit 201 receives an input indicating that it will use the output data D2 obtained by the simulation to calculate the required time Δt and the amount of power consumed H (step S31: simulation), the operation of the terminal device 2 proceeds to step S32. In step S31, if the reception unit 201 receives an input indicating that it will use the operation data D3 obtained from the temporary installation of the actual machine to calculate the required time Δt and power consumption H (step S31: actual machine), the operation of the terminal device 2 proceeds to step S33.
[0132] In step S32, the calculation unit 203 performs a simulation using the simulation model 222 described above. Specifically, the calculation unit 203 uses some or all of the building information J11 acquired in the acquisition phase S1 and the evaluation condition data D0 acquired in the calculation condition determination phase S2 as input to the simulation model 222. The calculation unit 203 acquires data on the temperature distribution of the target space S and data on the power consumption of the air conditioning equipment 1 installed in the target space S as output data D2 of the simulation model 222.
[0133] As described above, in step S24, the acquisition unit 202 is configured to acquire whether or not each of the air conditioners in the introduction case and the control case performs circulation operation as an operating method for the air conditioning system 1. Therefore, by inputting the settings in step S24, in step S32, the calculation unit 203 can set whether or not to perform circulation operation for any air conditioner in the introduction case and the control case in the simulation using the simulation model 222.
[0134] Step S32 ends when the calculation unit 203 acquires the output data D2 from the simulation model 222, and the operation of the terminal device 2 proceeds to step S34.
[0135] In step S33, the calculation unit 203 acquires the operation data D3. The operation data D3 acquired by the calculation unit 203 in step S33 is data acquired from the air conditioning equipment 1 that was installed based on the evaluation condition data D0 acquired by the acquisition unit 202 in the calculation condition determination phase S2. Specifically, in step S33, the calculation unit 203 transmits information to the server device 3 via the network NW requesting the operation data D3 for the air conditioning equipment 1 of the target space S. The calculation unit 203 also acquires the operation data D3 for the air conditioning equipment 1 of the target space S that is transmitted from the server device 3. The operating data D3 acquired by the calculation unit 203 in step S33 may be, for example, data collected by the server device 3 before the start of calculation phase S3. In this case, the air conditioning equipment 1 may be temporarily installed in the target space S before the start of calculation phase S3.
[0136] Step S33 ends when the calculation unit 203 acquires the operation data D3, and the operation of the terminal device 2 proceeds to step S34.
[0137] In step S34, the acquisition unit 202 acquires the locations of heat accumulation in the target space S. The acquisition unit 202 may acquire input that identifies heat accumulation locations in the target space S, which is received by the reception unit 201 via the input unit 23. Step S34 corresponds to an example of the “acquisition step” in this disclosure.
[0138] Alternatively, the acquisition unit 202 may acquire the heat accumulation locations in the target space S that have been identified by the heat accumulation location identification unit 205. In this case, the heat accumulation location identification unit 205 may identify the heat accumulation locations using the output data D2 of the simulation model acquired in step S32, the operation data D3 acquired in step S33, or the building information J11.
[0139] When using output data D2, the heat accumulation location identification unit 205, for example, refers to the temperature distribution of the target space S included in the output data D2 and identifies locations within the target space S where the temperature difference between the target space S and the optimal temperature Ts is greater than or equal to a predetermined temperature difference dT. The locations identified at this time are locations where heat accumulation occurs. The heat accumulation location identification unit 205 may also identify locations within the target space S that are frequently identified as locations where heat accumulation occurs, or locations that are identified for a long period of time, as heat accumulation locations.
[0140] When using the operating data D3, the heat accumulation location identification unit 205 refers, for example, to the measurement data of a temporarily installed thermosensor included in the operating data D3, and identifies locations in the target space S where the temperature difference between the target space S and the appropriate temperature Ts is greater than or equal to a predetermined temperature difference dT. The locations identified at this time are locations where heat accumulation occurs. The heat accumulation location identification unit 205 may also identify locations in the target space S where heat accumulation occurs frequently, or where it occurs for a long period of time, as heat accumulation locations.
[0141] Step S34 is completed when the acquisition unit 202 acquires the location of heat buildup, and the process moves on to step S35.
[0142] In step S35, the calculation unit 203 calculates at least one of the required time Δt or the power consumption H for both the introduction case and the control case. In this embodiment, the calculation unit 203 calculates the required time Δt and power consumption H for both the introduction case and the control case. Step S35 corresponds to an example of a “calculation step” in this disclosure. In calculating the required time Δt and power consumption H, the calculation unit 203 uses the output data D2 of the simulation model acquired in step S32, or the operation data D3 acquired in step S33. In addition, the calculation unit 203 uses the information that identifies the heat accumulation locations acquired by the acquisition unit 202 in step S34.
[0143] For example, when using output data D2, the calculation unit 203 first refers to the temperature distribution of the target space S included in the output data D2 and extracts the temperature of the heat accumulation location identified in step S34. Next, the calculation unit 203 identifies, for example, the point in time when the temperature of the extracted heat accumulation location is at a temperature that is more than or equal to a predetermined temperature difference dT from the optimal temperature Ts, that is, the point in time when heat accumulation occurs at the heat accumulation location, and sets the identified point in time as the start of the evaluation. Alternatively, the point in time when no heat accumulation occurs at the heat accumulation location may also be set as the start of the evaluation. Next, the calculation unit 203 refers to the temperature of the heat accumulation area and identifies the point in time when the reference temperature T9 is first reached since the start of the evaluation, and sets this identified point in time as the end of the evaluation. The calculation unit 203 calculates the time from the start of the evaluation to the end of the evaluation as described above, and sets the calculated value as the required time Δt.
[0144] Furthermore, the calculation unit 203 calculates the amount of energy H from, for example, the power consumption or energy consumption information of the air conditioning equipment 1 from the start of the evaluation to the end of the evaluation, as described above, in the output data D2. For example, if the output data D2 includes the energy consumption at each time for each air conditioning equipment 1 installed in the target space S, the calculation unit 203 may calculate the sum of the energy consumption at each time during the period from the start of the evaluation to the end of the evaluation and take the calculated sum as the amount of energy H. Alternatively, if the output data D2 includes power consumption instead of energy consumption, the calculation unit 203 may determine the amount of energy H by numerical integration of the power consumption during the period from the start of the evaluation to the end of the evaluation.
[0145] When using the operating data D3, the calculation unit 203 first refers to the measurement data such as that from a thermosensor included in the operating data D3 and extracts the temperature of the heat accumulation location identified in step S34. Then, using the extracted temperature of the heat accumulation location, the calculation unit 203 calculates the required time Δt in the same manner as when using the output data D2 described above. Alternatively, the calculation unit 203 may use the power consumption or energy consumption information of each air conditioning unit 1 included in the operating data D3 to determine the energy consumption H in the same manner as when using the output data D2 described above.
[0146] As described above, in this embodiment, the air conditioners installed in the target space S are selected by the model selection unit 207 or the selector P1 such that the capacity of the air conditioner in the installation case is smaller than that of the target case. Therefore, the output data D2 or operation data D3 used by the calculation unit 203 to calculate the required time Δt and power consumption H are obtained under the condition that the capacity of the air conditioner in the installation case is smaller than the capacity of the air conditioner in the target case. In other words, the calculation unit 203 in this embodiment calculates at least one of the required time Δt or power consumption H under evaluation conditions in which the capacity of the air conditioner in the installation case is smaller than the capacity of the air conditioner in the target case.
[0147] Furthermore, in this embodiment, the acquisition unit 202 automatically adopts the operation method of operating the air conditioning equipment 1 in the introduction case as the evaluation condition data D0, which is to operate the fan when the time of heat accumulation is less than or equal to a predetermined time, or when the frequency of heat accumulation is less than or equal to a predetermined frequency. For this reason, in the target space S, when the time of heat accumulation is less than or equal to a predetermined time, or when the frequency of heat accumulation is less than or equal to a predetermined frequency, the output data D2 or operation data D3 used by the calculation unit 203 to calculate the required time Δt and power consumption H are obtained under conditions where the fan is operating in the introduction case and the air conditioner is operating in the control case. In other words, the calculation unit 203 of this embodiment calculates at least one of the required time Δt or power consumption H under the evaluation condition that the fan is operated in the introduction case and the air conditioner is operated in the control case when the time of heat accumulation is less than or equal to a predetermined time, or when the frequency of heat accumulation is less than or equal to a predetermined frequency.
[0148] Furthermore, in this embodiment, the acquisition unit 202 refers to the building information J11 and, if the thermal insulation performance of building BL is below a predetermined thermal insulation performance, increases the airflow rate of the blower in the introduction case in the evaluation condition data D0 compared to when the thermal insulation performance is not below the predetermined thermal insulation performance. Therefore, the output data D2 or operation data D3 used by the calculation unit 203 to calculate the required time Δt and power consumption H are obtained under the condition that, when the thermal insulation performance of building BL is below a predetermined thermal insulation performance, the airflow rate of the blower in the introduction case is greater than when the thermal insulation performance exceeds the predetermined thermal insulation performance. In other words, the calculation unit 203 in this embodiment calculates at least one of the required time Δt or power consumption H under the condition that, when the thermal insulation performance of building BL is below a predetermined thermal insulation performance, the airflow rate of the blower in the introduction case is greater than when the thermal insulation performance exceeds the predetermined thermal insulation performance.
[0149] Furthermore, in this embodiment, if the acquisition unit 202 determines that multiple outdoor units are installed outside the target space S, it automatically adopts an operation method as evaluation condition data D0 for the implementation case, in which the fan is used to eliminate temperature unevenness in the target space S when the difference in load ratios between the multiple outdoor units is greater than or equal to a predetermined value. For this reason, the output data D2 or operation data D3 used by the calculation unit 203 to calculate the required time Δt and power consumption H are obtained under the condition that, when multiple outdoor units are installed outside the target space S, the fan is used to eliminate temperature unevenness in the target space S when the difference in load ratios between the multiple outdoor units is greater than or equal to a predetermined value. In other words, the calculation unit 203 of this embodiment calculates at least one of the required time Δt or power consumption H in the implementation case in which multiple outdoor units are installed outside the target space S, and the fan is used to eliminate temperature unevenness in the room when the difference in load ratios between the multiple outdoor units is greater than or equal to a predetermined value, thereby equalizing the load ratios between the multiple outdoor units. For example, the load factor of an outdoor unit may be given as the ratio of the current value of the outdoor unit to the rated current value of the outdoor unit. Here, we focused on the outdoor unit, but if there are multiple indoor units, the load factors between the indoor units can be equalized using a fan. The load factor of an indoor unit can be estimated, for example, by the difference between the set temperature and the intake temperature of each indoor unit. In this case, it can also be applied to configurations such as GHP and VRF, where multiple indoor units are housed in a single air conditioner.
[0150] Furthermore, in this embodiment, when a ventilation device is installed in the target space S, the acquisition unit 202 automatically adopts an operating method as evaluation condition data D0 in the introduction case, in which the air conditioner is stopped and outside air cooling operation is performed when outside air cooling operation is possible using the ventilation device, and the fan is operated during the outside air cooling operation. For this reason, the output data D2 or operation data D3 used by the calculation unit 203 to calculate the required time Δt and power consumption H are obtained under the condition that, when a ventilation device is installed in the target space S, the air conditioner is stopped and outside air cooling operation is performed when outside air cooling operation is possible using the ventilation device, and the fan is operated during the outside air cooling operation. In other words, the calculation unit 203 of this embodiment calculates at least one of the required time Δt or power consumption H in the introduction case in which a ventilation device is installed in the target space S, it is possible to perform outside air cooling operation by ventilation that takes in outside air by stopping the air conditioner and taking in outside air using the ventilation device, and the fan is operated while the outside air cooling operation is being performed.
[0151] Step S35 ends when the calculation unit 203 completes the calculation of the required time Δt or power consumption H for both the introduction case and the control case, and the operation of the terminal device 2 proceeds to step S36.
[0152] In step S36, the calculation unit 203 calculates the sound power level. For example, the calculation unit 203 may obtain the model and airflow rate of the air conditioner and blower in the target space S from the evaluation condition data D0, output data D2, or operation data D3, and calculate the sound power level in the target space S by comparing the obtained model and airflow rate information with the sound data 223. Specifically, the sound data 223 defines the relationship between the airflow rate of the blower and the noise generated, using blower specifications information described in product catalogs, etc. The noise value increases as the airflow rate increases. The noise value (e.g., decibel value) is obtained from the airflow rate using this specification information. Alternatively, for example, the calculation unit 203 may obtain the detected value of the sound level meter included in the operation data D3 and determine the sound power level of the target space S from the obtained detected value.
[0153] In step S37, the depreciation period calculation unit 206 calculates the depreciation period L of the blower in the installation case. At this time, the depreciation period calculation unit 206 may use, for example, the above-described formula (5) or formula (6).
[0154] In this case, the amortization period calculation unit 206 may use the power consumption H1 of the introduction case and the power consumption H2 of the control case, calculated in step S35, when calculating the amortization period L. Alternatively, the amortization period calculation unit 206 may refer to the introduction cost C of the blower and the electricity rate c0 per unit of power stored in the memory 220 and use them to calculate the amortization period L. Furthermore, the amortization period calculation unit 206 may extract the temperature of heat accumulation points from the output data D2 or operation data D3, calculate the average interval I of heat accumulation at the heat accumulation points, and use this to calculate the amortization period L. In addition, the amortization period calculation unit 206 may obtain the model and number of air conditioning equipment 1 to be introduced in the introduction case and the control case, respectively, from the evaluation condition data D0, compare this with the cost data 224, find the difference ΔC in the introduction cost of the air conditioning equipment 1 between the control case and the introduction case, and use this to calculate the amortization period L. The amortization period calculation unit 206 may use values specified by the input operation received by the reception unit 201 via the input unit 23 as the average occurrence interval I, introduction cost C, difference ΔC, and electricity charge c0.
[0155] Upon completion of step S37, terminal device 2 terminates its operation in calculation phase S3.
[0156] [1-2-2-4. Output Phase] Next, in output phase S4, the display unit 204 outputs at least one of the required time Δt or the power consumption H. Figure 7 is a diagram showing an example of the calculation result screen G02. In output phase S4, the display unit 204 displays the calculation result screen G02 shown in Figure 7 using the display 22. Output phase S4 corresponds to an example of the "output step" in this disclosure.
[0157] The calculation results screen G02 has an implementation case display area A1 and a comparison case display area A2. The implementation case display area A1 is the area in the calculation results screen G02 that displays information about the implementation case. The comparison case display area A2 is the area in the calculation results screen G02 that displays information about the comparison case. Specifically, the implementation case display area A1 displays at least one of the required time Δt or the power consumption H for the implementation case. The comparison case display area A2 displays at least one of the required time Δt or the power consumption H for the comparison case. In the example in Figure 7, the implementation case display area A1 is provided in the upper half of the calculation results screen G02, and the comparison case display area A2 is provided in the lower half of the calculation results screen G02.
[0158] Case identification information J2 is displayed in the introduction case display area A1 and the control case display area A2. Case identification information J2 identifies whether the information displayed in the area where case identification information J2 is provided belongs to the introduction case or the control case. For example, in the example in Figure 7, case identification information J2A, which is case identification information J2 provided in the introduction case display area A1, contains the words "Air conditioner + circulator combination". In this example, case identification information J2A indicates that the introduction case display area A1 where case identification information J2A is provided will display information for a case that combines an air conditioner and a circulator (a fan), i.e., the introduction case. Also in the example in Figure 7, case identification information J2B, which is case identification information J2 provided in the control case display area A2, contains the words "Air conditioner only". In this example, case identification information J2B indicates that the control case display area A2 where case identification information J2B is provided will display information for a case that has an air conditioner but does not have a fan, i.e., the control case.
[0159] The required time information J3 is displayed in the implementation case display area A1 and the control case display area A2. The required time information J3 is information indicating the required time Δt calculated in step S35. In the example in Figure 7, the required time information J3 includes a graph with the horizontal axis representing time since the start of the evaluation and the vertical axis representing the temperature at the heat accumulation point (user position), and a dashed line indicating the required time Δt superimposed on the graph. In the required time information J3 of Figure 7, the required time Δt is indicated by the dashed line and the words "6 minutes" or "9 minutes" placed near the dashed line. Specifically, the required time information J3A, which is the required time information J3 provided in the implementation case display area A1, shows the required time Δt in the implementation case. The required time information J3B, which is the required time information J3 provided in the control case display area A2, shows the required time Δt in the control case.
[0160] Power consumption information J4 is displayed in the introduction case display area A1 and the control case display area A2. Power consumption information J4 is information indicating the power consumption H calculated in step S35. In the example in Figure 7, power consumption information J4 shows the power consumption H in text, such as "Power consumption XX Wh" and "Power consumption ZZ Wh". Specifically, power consumption information J4A, which is power consumption information J4 provided in the introduction case display area A1, shows the power consumption H1 in the introduction case. Also, power consumption information J4B, which is power consumption information J4 provided in the control case display area A2, shows the power consumption H2 in the control case.
[0161] The acoustic power level information J5 is displayed in the introduction case display area A1 and the control case display area A2. The acoustic power level information J5 is information indicating the acoustic power level calculated in step S36. In the example in Figure 7, the acoustic power level information J5 shows the acoustic power level in text, such as "Acoustic power level YY dB" and "Acoustic power level WW dB". Specifically, the acoustic power level information J5A provided in the introduction case display area A1 shows the acoustic power level in the introduction case. The acoustic power level information J5B provided in the control case display area A2 shows the acoustic power level in the control case.
[0162] The depreciation period information JL is displayed in the installation case display area A1. The depreciation period information JL is information indicating the depreciation period L of the blower in the installation case calculated in step S37. In the example in Figure 7, the depreciation period information JL shows the depreciation period L of the blower in text, such as "Depreciation period of blower Q years".
[0163] In the example shown in Figure 7, the introduction case display area A1 and the comparison case display area A2 are displayed on a single calculation result screen G02. However, the introduction case display area A1 and the comparison case display area A2 may be displayed on multiple separate screens. In this case, the display unit 204 may be configured to switch the screen displayed on the display 22 between a screen containing the introduction case display area A1 and a screen containing the comparison case display area A2, for example, when the reception unit 201 receives a predetermined input operation from the input unit 23.
[0164] Figure 8 shows an example of the layout screen G03. In the output phase S4, the display unit 204 further displays the layout screen G03 shown in Figure 8 using the display 22. The display unit 204 may be configured to switch between the calculation result screen G02 and the layout screen G03 when, for example, the reception unit 201 receives a predetermined input operation from the input unit 23.
[0165] Layout screen G03 has an implementation case display area A3 and a comparison case display area A4. The implementation case display area A3 is the area on layout screen G03 that displays information about the implementation case. The comparison case display area A4 is the area on layout screen G03 that displays information about the comparison case. In the example in Figure 8, the implementation case display area A3 is provided in the lower half of layout screen G03, and the comparison case display area A4 is provided in the upper half of layout screen G03.
[0166] Case identification information J6 is displayed in the introduction case display area A3 and the comparison case display area A4. Case identification information J6 identifies whether the information displayed in the area where case identification information J6 is provided belongs to the introduction case or to the comparison case. For example, in the example in Figure 8, case identification information J6A, which is case identification information J6 provided in the introduction case display area A3, contains the text "Composed of an air conditioner and a blower". In this example, case identification information J6A indicates that in the introduction case display area A3 where case identification information J6A is provided, information for the air conditioning equipment 1 consisting of an air conditioner and a blower is displayed, i.e., the introduction case. Also in the example in Figure 8, case identification information J6B, which is case identification information J6 provided in the comparison case display area A4, contains the text "Composed of an air conditioner only". In this example, case identification information J6B indicates that in the comparison case display area A4 where case identification information J6B is provided, information for a case in which the air conditioning equipment 1 consists only of an air conditioner and does not include a blower is displayed, i.e., the comparison case.
[0167] Layout diagram I2 is displayed in the display area A3 of the installation case and the display area A4 of the comparison case. Layout diagram I2 is an image that can show the locations of air conditioners, blowers, and heat accumulation areas in the target space S.
[0168] Layout diagram I2 includes a target space image I21, which schematically represents the target space S. In the example in Figure 8, the target space image I21 schematically represents a plan view of the target space S. Also in the example in Figure 8, the target space image I21 shows the target space S with obstacles that obstruct airflow placed within it. Layout diagram I2 includes an air conditioner image I22, which schematically represents an air conditioner. The air conditioner image I22 is superimposed on the target space image I21, and the position in which it is superimposed on the target space image I21 indicates the position of the air conditioner in the target space S. Layout diagram I2 may include a fan image I23, which schematically represents a fan such as a circulator. The fan image I23 is superimposed on the target space image I21, and the position in which it is superimposed on the target space image I21 indicates the position of the fan in the target space S. Layout diagram I2 may include a difference image I24, which is an image showing the air conditioners installed in the control case but not in the installation case. The difference image I24 is superimposed on the target space image I21, and the position in which it is superimposed on the target space image I21 indicates the position of the air conditioners not installed in the installation case in the target space S of the control case. In reality, the air conditioners shown in the difference image I24 are not installed in the target space S of the installation case, so the difference image I24 is shown with dashed lines. Layout diagram I2 includes a heat accumulation image I25, which schematically shows heat accumulation areas. The position in which the heat accumulation image I25 is superimposed on the target space image I21 indicates the location of heat accumulation areas in the target space S. Layout diagram I2 may include a wind direction image I26 showing the direction of the airflow blown out from the air conditioner or blower. In the example in Figure 8, the wind direction image I26 is an arrow, indicating that the airflow flows in the direction the arrowhead points.
[0169] The installation case display area A3 is provided with layout diagram I2A, which is layout diagram I2 for the installation case. Layout diagram I2A includes the target space image I21 and the air conditioner image I22, blower image I23, difference image I24, heat accumulation image I25, and wind direction image I26, which are superimposed on the target space image I21. In other words, layout diagram I2A for the installation case shows the locations of the air conditioner, blower, and heat accumulation areas in the target space S. The comparison case display area A4 is provided with layout diagram I2B, which is layout diagram I2 for the comparison case. Layout diagram I2B includes the target space image I21, and the air conditioner image I22, heat accumulation image I25, and wind direction image I26 superimposed on the target space image I21. In other words, layout diagram I2B for the comparison case shows the locations of the air conditioner and heat accumulation areas in the target space S. For example, the air conditioner image I22, the blower image I23, the difference image I24, and the wind direction image I26 are placed on the target space image I21 based on, for example, the information on the arrangement and orientation of each air conditioning equipment 1 included in the evaluation condition data D0. Also, the heat accumulation image I25 is placed on the target space image I21 based on, for example, the location information of the heat accumulation area acquired by the acquisition unit 202 in step S34.
[0170] The heat accumulation temperature information J7 is displayed in the introduction case display area A3 and the control case display area A4. The heat accumulation temperature information J7 indicates the temperature of the heat accumulation location at the start of the evaluation in step S35. In the example in Figure 8, the heat accumulation temperature information J7 shows the temperature of the heat accumulation location at the start of the evaluation in text, such as "Temperature near heat accumulation: 35°C". Specifically, the heat accumulation temperature information J7A, which is provided in the introduction case display area A3, shows the temperature of the heat accumulation in the introduction case at the start of the evaluation. The heat accumulation temperature information J7B, which is provided in the control case display area A4, shows the temperature of the heat accumulation in the control case at the start of the evaluation.
[0171] The required time information J8 is displayed in the introduction case display area A3 and the control case display area A4. The required time information J8 is information that shows the required time Δt calculated in step S35. In the example in Figure 8, the required time information J8 shows the required time Δt in text, such as "Time until heat buildup is eliminated: 7 minutes" and "Time until heat buildup is eliminated: 6 minutes". Specifically, the required time information J8A, which is provided in the introduction case display area A3, shows the required time Δt in the introduction case. The required time information J8B, which is provided in the control case display area A4, shows the required time Δt at the start of the evaluation in the control case.
[0172] Capacity-related information J9 is displayed in the installation case display area A3 and the comparison case display area A4. Capacity-related information J9 displays information about the capacity of the air conditioner. Information about the capacity of the air conditioner may include, for example, information about the specifications of the air conditioner, i.e., the product model number (model), capacity, power consumption, or COP. Information about the capacity of the air conditioner may also include information about the costs associated with the air conditioner, such as the installation cost and running costs. In the example in Figure 8, capacity-related information J9 shows the installation cost of the air conditioner in text, such as "Installation cost X yen" and "Installation cost Y yen," as information about the capacity of the air conditioner. Specifically, capacity-related information J9A, which is displayed in the installation case display area A3, shows the installation cost of the air conditioner in the installation case. Also, capacity-related information J9B, which is displayed in the comparison case display area A4, shows the installation cost of the air conditioner in the comparison case. In either case, the temperature and wind speed at different distances reached by the airflow from each device may also be visualized. The method for calculating the temperature and wind speed at different distances may be, for example, equations (9) and (10) described in Use Case 2 and Use Case 3 below. In a real-world setup, multiple wind speed sensors and temperature sensors may be placed in the target space S, and the data from each sensor may be displayed on the screen sequentially.
[0173] [1-2-3. Use Cases] Next, use cases for applying the equipment installation support services provided by the blower installation support system 1000 to various target spaces S will be described below. The following use cases can be used as evaluation conditions for simulations to acquire output data D2, or for the temporary installation of actual air conditioning equipment 1 to acquire operation data D3. Note that the equipment may also be permanently installed rather than temporarily installed. In the case of permanently installed equipment, the operational effects can be clarified through analysis of the equipment's operation data, etc., which can be used as reference information for equipment users when replacing equipment, and as information for promoting equipment sales for equipment vendors.
[0174] [1-2-3-1. Use cases when the target space is an office or store, etc.] First, we will explain an example of application when the target space S is an office or a store. The air conditioning equipment 1 that is expected to be installed in the target space S may include, for example, a packaged air conditioner as an air conditioner, and for example, a circulator, transport fan, ceiling fan, or air curtain as a blower.
[0175] In the following, we will describe use cases 1 to 3 as implementation cases or control cases for the equipment installation support service provided by the fan installation support system 1000, assuming that the target space S is an office or a store, etc.
[0176] (Use Case 1) The following describes Use Case 1, an example of an implementation scenario.
[0177] (Placement of each device in the target space) First, we will describe the arrangement of each device in the target space S of Use Case 1. Figure 9 is a schematic diagram of the target space S in Use Case 1. In the figure, the symbol X indicates the left direction in the target space, and the symbol Z indicates the upward direction in the target space.
[0178] As shown in Figure 9, in Use Case 1, an air conditioner 101, which is the indoor unit of a packaged air conditioner, is installed in the target space S as the air conditioning equipment 1. The air conditioner 101 is installed on the ceiling or on a wall near the ceiling in the target space S.
[0179] As shown in Figure 9, in Use Case 1, a circulator, or blower, 111 is installed in the target space S as the air conditioning equipment 1. The blower 111 is mounted on the wall surface of the target space S. In this embodiment, the blower 111 is mounted on the left wall surface. The blower 111 blows air upward. Therefore, the air blown out by the blower 111 flows upward along the left side of the target space S, reaches the ceiling surface, and then flows to the right.
[0180] As shown in Figure 9, in Use Case 1, a temperature sensor 121A is provided in the target space S. The temperature sensor 121A is installed at a height near the ceiling surface of the target space S. The temperature sensor 121A detects the temperature at a height near the ceiling surface in the target space S. Note that the temperature sensor 121A may be implemented using the intake temperature sensor of the air conditioner 101.
[0181] As shown in Figure 9, in Use Case 1, an infrared sensor 121B is provided in the target space S. The infrared sensor 121B is installed on the ceiling surface or the like of the target space S. The infrared sensor 121B detects the temperature of the floor surface in the target space S.
[0182] In Use Case 1, the air conditioner 101, blower 111, temperature sensor 121A, and infrared sensor 121B, all located in the target space S, are connected to the control device 191. The control device 191 includes memory and a processor, etc. The control device 191 receives the temperatures detected by the temperature sensor 121A and the infrared sensor 121B. The control device 191 controls the air conditioner 101 and the blower 111.
[0183] (Operating conditions for each device) In Use Case 1, the air conditioner 101 operates in a wind-shielding mode for heating or cooling. The wind-shielding mode refers to an operating mode in which the flaps of the air conditioner 101 are tilted to near horizontal so that the airflow blown out from the air conditioner 101 does not directly hit people. When the air conditioner 101 is operating in wind-shielding mode, the air blown out by the air conditioner 101, indicated by the black arrows in Figure 9, flows approximately horizontally along the ceiling, and after reaching the wall, it attempts to flow downward along the wall toward the floor. In the example in Figure 9, if the air blown out by the blower 111 described later is not considered, the air blown out by the air conditioner 101 flows to the left along the ceiling surface of the target space S, reaches the left wall, i.e., the wall on which the blower 111 is installed, and flows downward along the left wall.
[0184] Thus, the air discharged from the air conditioner 101 and the air discharged from the blower 111 flow in opposite directions along the walls, ceiling, and floor of the target space S. In other words, the blower 111 blows air in the opposite direction to the airflow generated by the air conditioner 101. Therefore, as shown in Figure 9, when the air conditioner 101 and the blower 111 are operating simultaneously, the air discharged from the air conditioner 101 and the air discharged from the blower 111 collide near the ceiling of the target space S, creating a downward airflow. This downward airflow makes it easier to equalize the temperature of the target space S. In addition, in use case 1, since the blower 111 blows air upward, when a person standing on the floor approaches the blower 111, it is possible to suppress the airflow from directly hitting the person, making it easier to reduce the sensation of airflow. Furthermore, the direction of the airflow generated by the air conditioner 101, as referred to here, includes not only the direction in which air is blown out of the air conditioner 101, but also the direction of the air after it has been blown out of the air conditioner 101 and has changed direction after colliding with the ceiling, walls, or floor of the target space S.
[0185] Furthermore, in Use Case 1, the blower 111 operates with an airflow rate corresponding to the temperature difference between the temperature at ceiling height and the floor temperature in the target space S. Specifically, the control device 191 calculates the temperature difference between the temperature at ceiling height in the target space S, obtained via the temperature sensor 121A, and the temperature of the floor in the target space S, obtained via the infrared sensor 121B. When the calculated temperature difference is large, the control device 191 controls the blower 111 to have a larger airflow rate than when the temperature difference is small. In the target space S, due to differences in air density, cold air tends to accumulate near the floor and warm air tends to accumulate near the ceiling, which can lead to uneven temperature distribution in the vertical direction. However, by controlling the blower 111 according to the temperature difference, it is possible to easily eliminate this uneven temperature distribution.
[0186] (Calculation and output of results) In Use Case 1, the calculation unit 203 sets the optimal temperature Ts as the set temperature of the air conditioner 101, and the temperature of the floor surface or near the ceiling of the target space S as the temperature of the heat accumulation point. The calculation unit 203 then calculates the power consumption H of the air conditioner 101 and the blower 111 during the required time Δt.
[0187] The display unit 204 uses the display 22 to display the required time Δt and power consumption H calculated by the calculation unit 203.
[0188] (Variation of Use Case 1) In Use Case 1, it was explained that the blower 111 is installed on the wall surface of the target space S, but the blower 111 may also be installed on the floor surface or ceiling surface of the target space S. Furthermore, the blower 111 may be configured to blow air in the same direction as the airflow generated by the air conditioner 101. In this case, it is easier to promote air circulation in the target space S.
[0189] (Use Case 2) Below, we will describe Use Case 2, which is an example of a contrasting case. (Placement of each device in the target space) The arrangement of each device in the target space S of Use Case 2 will be described. Figure 10 is a schematic diagram showing the target space S in Use Case 2.
[0190] As shown in Figure 10, in Use Case 2, an air conditioner 102, which is the indoor unit of a packaged air conditioner, is installed in the target space S as the air conditioning equipment 1. The air conditioner 102 is installed on the ceiling or on a wall near the ceiling in the target space S.
[0191] In Use Case 2, a temperature and humidity sensor 122A is provided in the target space S. The temperature and humidity sensor 122A is installed on the wall or ceiling surface of the target space S. The temperature and humidity sensor 122A detects the temperature and humidity in the target space S. Note that the temperature and humidity sensor 122A may also be installed in an air conditioning unit such as an air conditioner 102 or a ventilation device (e.g., a total heat exchanger or an outside air processing unit).
[0192] In Use Case 2, an infrared sensor 122B is installed in the target space S. The infrared sensor 122B is installed on the ceiling surface or the like in the target space S. The infrared sensor 122B detects the temperature of the floor surface, human body, and equipment surface in the target space S.
[0193] In Use Case 2, the air conditioner 102, temperature and humidity sensor 122A, and infrared sensor 122B are connected to the control unit 192. The control unit 192 includes memory and a processor, etc. The control unit 192 controls the air conditioner 102. The control unit 192 acquires the detected values of the temperature and humidity sensor 122A and the infrared sensor 122B.
[0194] (Operating conditions for each device) In Use Case 2, the air conditioner 102 is controlled so that the PMV at the position of the person in the target space S reaches the target value. There are six factors that affect the thermal comfort of the human body, namely four physical factors: room temperature, mean radiant temperature, relative humidity, and wind speed, and two human-related factors: the clothing amount and the workload of the occupants in the room. It is advisable to use PMV for the evaluation of the thermal environment within the range of -2 to +2. The ISO standard recommends a thermal environment in which PMV is within ±0.5 and the discomfort rate is 10% or less. PMV is calculated by the control device 192 as follows. By calculating only, the realization cost can be reduced compared to using a PMV sensor. The control device 192 first determines the temperature θ of the target space S acquired by the temperature and humidity sensor 122A a and the surface temperature T acquired by the infrared sensor 122B f and substitutes them into the following formula (7) to calculate the globe temperature T g . T g =α·T f +(1-α)·θ a (7) Here, α is a parameter. For example, the value of α is set to 0.5. However, the value of α may be changed in consideration of factors such as the heat insulation performance of the building and the influence of the floor temperature.
[0195] Next, the control device 192 uses the globe temperature T obtained by formula (7) g to calculate the mean radiant temperature MRT. The calculation of MRT is performed using the following formula (8). MRT=T g +2.35·V a 0.5 ·(T g ―θ a ) (8) MRT represents the heat or coolness caused by the radiant heat received by a person from the surroundings. Here, the globe temperature was calculated, but the value measured with a globe thermometer may also be used. Here, V a indicates the air flow velocity.
[0196] Furthermore, the control device 192 calculates the PMV using the MRT obtained by equation (8), the current temperature and humidity measured by the temperature and humidity sensor 122A, and the fixed values of the metabolic rate of a person in the target space S, the amount of clothing worn, and the airflow velocity near the person. Note that the metabolic rate of a person may be appropriately changed taking into account factors such as the type of activity, the person's physique, gender, and age, and the amount of clothing worn may be appropriately changed taking into account factors such as the season and gender. For example, in terms of the type of activity, the metabolic rate is 1 (MET) when sitting and relaxing, and 1.6 (MET) when standing and doing light work (light work, shopping, washing dishes). 1 MET = 58.2 W / m 2 This is the resting metabolic rate. For clothing, thin work clothes are 0.7 CLO, and a thick business suit is 1.5 CLO. 1 CLO = 0.155 m 2 The temperature becomes 0°C / W (when unprotected). Furthermore, the Building Environmental Hygiene Management Guidelines specify a value for managing the thermal environment so that the airflow velocity around people is 0.5 m / s or less. The control device 192 controls the set temperature of the air conditioner 102 to maintain the PMV determined as described above within the target range of -0.5 or greater and 0.5 or less.
[0197] (Use Case 3) The following section describes Use Case 3, an example of an implementation case. Note that the implementation case shown in Use Case 3 corresponds to the counter-case shown in Use Case 2.
[0198] (Placement of each device in the target space) This section describes the arrangement of each device in the target space S for Use Case 3. Figure 11 is a schematic diagram showing the target space S in Use Case 3.
[0199] As shown in Figure 11, the target space S in Use Case 3 is equipped with the same air conditioner 102, temperature and humidity sensor 122A, infrared sensor 122B, and control device 192 as the target space S in Use Case 2. In Use Case 3, the target space S is also equipped with a blower 112 as air conditioning equipment 1. The blower 112 is envisioned to be, for example, a floor-standing circulator or a circulator with adjustable airflow direction and volume, such that the direction and volume of airflow from the blower 112 can be easily adjusted by a person in the target space S.
[0200] (Operating conditions for each device) The operating conditions for the air conditioner 102 in Use Case 3 are the same as in Use Case 2. However, Use Case 3 assumes that the air conditioner 102 is operating in cooling mode.
[0201] In Use Case 3, the fan 112 blows air towards a person in the target space S. For example, the fan 112 can be operated by a person in the target space S to direct the airflow towards that person. When the airflow from the fan 112 hits a person, their perceived temperature decreases. In this way, for example, when multiple people are in the target space S, if their metabolic rates differ due to differences in physique, gender, etc., the set temperature alone may not be sufficient to adjust the temperature. In this case, differences in individual thermal sensitivity (e.g., being sensitive to heat, being sensitive to cold) can be adjusted by blowing air. Alternatively, a configuration may be provided in which a surveillance camera (thermal camera) is installed in the room, and the thermal camera identifies people with high skin surface temperatures or people close to the fan 112, and the fan 112 is equipped with airflow control to direct the airflow towards the face or shoulders of those people. Furthermore, the configuration may include a blower 112 that can determine the status of reaching the person based on changes in the surface temperature of the person's skin and change the airflow volume and direction accordingly, or detect if there is an obstacle in front of the person and change the airflow direction.
[0202] (Calculation and output of results) In use cases 2 and 3, the calculation unit 203 calculates the time required Δt as the time it takes from the start of the evaluation until the PMV at the person's position in the target space S falls within the range of -0.5 or greater and 0.5 or less. While PMV only expresses hot and cold, SET* allows for temperature expression. In SET*, a state of 22.2 to 25.6°C is defined as the comfortable range where more than 80% of people feel satisfied with the environment. Like PMV, SET* is calculated based on six elements of the thermal environment (amount of clothing, metabolic rate, air temperature, radiant temperature, wind speed, and humidity). In configurations where a fan is used to blow air onto a person (for example, use case 3 and the VZ nozzle use case shown below), comfort is generally indicated using SET*. In such use cases, the SET* of the surrounding area where the air is being blown is calculated, and one of the blown-out temperature θ0 and airflow velocity V0 from the fan is controlled so that it falls within the comfortable range of SET*. In the case of using a fan to blow air, the air temperature used is the air temperature and airflow velocity near the person generated by the air blown from the fan. These air temperatures θ a and airflow velocity V a This can be found using equations (9) and (10). θ a = 0.83·K·D0·θ0 / X (9) V a =K·D0·V0 / X (10) Here, K is the outlet constant (a constant determined by the type of outlet and the velocity from the outlet), D0 is the effective diameter of the outlet (a value listed in the product catalog, etc., expressed in meters), θ0 is the outlet temperature from the blower (°C), V0 is the outlet velocity from the fan (m / s), and X is the distance from the outlet (m). Specifically, X is a measured value using millimeter waves, etc., or a design value derived from the design drawings. Note that the air temperature θ a and airflow velocity V a The formulas used to calculate this are not limited to these calculation formulas. For example, formulas shown in the Air Conditioning and Sanitary Engineering Handbook may be used, or formulas may be derived using methods such as regression analysis based on measurement data collected in laboratories or installation sites. In industrial settings with heat-generating equipment, such as in a factory, the mean radiant temperature T r This can be calculated using equation (11). T r =(ΣF pi ·(θ i +273) 4 ) 0.25 ―273 (11) Here, θ i :Temperature of surrounding walls, ceiling, and floor (°C), F pi This refers to the shape factor of the surrounding walls, ceiling, floor, and the human body. It is the shape factor of the area covering the human body (e.g., 1m wide, 2m long), taking into account the positional relationship (distance) between the worker and the heat-generating surface. The shape factor is a coefficient that indicates the ratio of radiant energy emitted from one surface to reach another surface. Here, it is the shape factor that considers the heat-generating element (e.g., heat generation of 70°C from industrial equipment) in relation to the shape of the human body. Note that if you specify the operating temperature instead of the radiation temperature or air temperature using a tool or other means to calculate SET*, use the operating temperature T in equation (12). o Here, the mean radiation temperature T is given. r Using the operating temperature T o We seek. T o =( h c ·T a +h r ·T r ) / (h c +h r ) (12) Here, h c : Convective thermal conductivity (W / m 2 ·K), h r : Radiant thermal conductivity (W / m 2 ·K), T a : Air temperature (°C), T r : This is the mean radiant temperature (°C). The radiant thermal conductivity is 4 W / m 2 We treat K as an approximate constant. Here, the convective thermal conductivity is defined using the formula for forced convection, as shown in equations (13) and (14). The following equation is the convective thermal conductivity (rough surface) under forced convection, based on Jürges' experiment. h c = 6.2 + 4.3·V a (V a (≤4.9 m / s) (13) h c = 7.6·V a 0.78 (Va >4.9 m / s) (14) Since the convective heat transfer coefficient differs depending on the part of the human body, a convective heat transfer coefficient that takes into account the differences in the human body parts may be used to improve calculation accuracy. Furthermore, although a calculation formula has been shown, it may also be possible to determine the radiant temperature using a black globe thermometer.
[0203] The display unit 204 uses the display 22 to display the required time Δt for use cases 2 and 3 in a comparable manner. The display unit 204 also uses the display 22 to display information about PMV and SET* at the position of a person in the target space S for use cases 2 and 3. In addition, for blowers that oscillate, such as VZ nozzles, the exposure rate to a person may be defined from the oscillation angle and oscillation speed of the blower, and a calculation of SET* that is appropriate to the actual usage of the VZ nozzle may be performed and output.
[0204] [1-2-3-2. Application examples when the target space is a large space such as a factory] Next, we will describe a use case when the target space S is a large space such as a factory. When the target space S is a large space such as a factory, the air conditioning equipment 1 that is expected to be introduced to the target space S may include, for example, a packaged air conditioner as an air conditioner, and for example, a VZ nozzle as a blower. For example, the VZ nozzle is a high-performance nozzle with minimal energy diffusion that enables zone air conditioning in large spaces such as factories. By using the VZ nozzle to zone-air-condition the necessary space, cooling can be achieved with less energy than whole-house air conditioning using only air conditioners. The VZ nozzle improves the reach of the cool air, lowering the perceived temperature through exposure to the cool air. Therefore, even if the outlet temperature is increased, the same level of comfort as whole-house air conditioning can be achieved. In addition, the outlet can be swung from side to side. Furthermore, comfort can be improved with intermittent fluctuating airflow. The effective area can be expanded to accommodate human movement, and the airflow spread can be set in four stages: 0, 60, 90, and 120 degrees, according to the activity area. It can also be manually set vertically by 80 degrees. Based on these settings, the swing width and swing speed of the VZ nozzle can be controlled. As for how to determine the settings for the VZ nozzle, in the example of a factory, the work area is defined in the building plan, the center of gravity of the work area is determined, and the direction of the VZ nozzle is determined so that the center of the airflow passes through the center of gravity. Furthermore, the swing width and swing speed of the VZ nozzle are determined so that the airflow from the VZ nozzle covers the work area. Specific examples of VZ nozzle use include, when used in cooling and heating operations, stratified air conditioning in summer through the effect of an upper and lower air curtain (for example, at a height of 2-3m from the floor) and uniform air conditioning through agitation. In transitional seasons such as spring and autumn, VZ nozzles can be used, for example, to save energy through a fan effect, or to lower the perceived temperature by taking in outside air and creating a swing airflow. In transitional seasons, introducing low-temperature outside air through VZ nozzles can also reduce the load on the air conditioner. In winter, VZ nozzles can be used, for example, to bring warm air down to the feet and reduce temperature differences (for example, a temperature difference of 2-3°C or less between the upper and lower parts of the room). Furthermore, by using VZ nozzles, it is possible to blow out cold air without mixing the generated heat with the blown air in places where there is a lot of internal heat generation (e.g., industrial equipment). It should be noted that the present invention is not limited to the specifications of the VZ nozzle described above. For example, the VZ nozzle may be configured to automatically swing left, right, up, and down in accordance with a specific person. The VZ nozzle may also be configured for use in general spot air conditioning systems. Methods for making the fan swing motion follow a specific person include image processing using a visible light camera or thermal camera, or data processing of point clouds obtained using millimeter waves. In the following sections, we will describe use cases 4 and 5 as examples of the equipment installation services provided by the blower installation support system 1000, assuming that the target space S is a large space such as a factory.
[0205] (Use Case 4) The following describes Use Case 4, an example of an implementation case.
[0206] (Placement of each device in the target space) First, we will describe the arrangement of each device in the target space S of Use Case 4. Figure 12 is a schematic diagram showing the target space S in Use Case 4.
[0207] As shown in Figure 12, in Use Case 4, an outdoor unit, an air conditioner 104, is installed outside the target space S. The air conditioner 104 in Use Case 4 does not have an indoor unit and blows air into the target space S via a blower 114, which is a VZ nozzle. The air conditioner 104 is configured to allow adjustment of the temperature and airflow rate of the blown air. In other words, the air conditioner 104 can adjust the airflow rate of the blower 114. The blower 114 adjusts the airflow direction of the air conditioner 104.
[0208] In Use Case 4, a surveillance camera 124A is installed in the target space S. The surveillance camera 124A is a device that photographs the target space S and acquires video footage of the target space S. Alternatively, a thermal sensor or millimeter-wave radar may be installed in the target space S instead of the surveillance camera 124A.
[0209] In Use Case 4, a measuring device 124B is installed in the target space S. The measuring device 124B is a device capable of acquiring measurements of the four thermal elements (air temperature, relative humidity, black globe temperature, and wind speed) in the work area of the target space S. Specifically, it consists of a thermometer, a hygrometer, a black globe thermometer, etc. The measuring device is configured to periodically collect measurement data via wired or wireless connection. In addition, a system used for heatstroke diagnosis also collects similar data, so its sensor data may be utilized. The work area is the area in the target space S where a person performs work. In other words, in the target space S, a person is located in the work area. Specifically, the layout of industrial equipment and the work area of workers are identified using building plans. If the building base line (BL) is already in place, a thermal camera is used to understand the heat accumulation situation within the work area. For newly constructed building bedrock (BLs), airflow analysis tools are used to model factors contributing to heat buildup, such as the concentration of workers (human heat generation) and heat generated by industrial equipment. The size and amount of heat generated within the building are then simulated. Furthermore, VZ nozzles are placed within the simulation model, directed towards the work area, and the temperature and airflow distribution within the work area are simulated. Based on the airflow analysis results, the type of VZ nozzle, as well as its airflow direction and volume, are determined. For air conditioners, the set temperature is determined. The specifications of the models are defined by at least the rated heating and cooling capacity for air conditioners and the maximum airflow that can be supplied for VZ nozzles. Note that a coupled calculation with an energy simulator is also possible in addition to the airflow analysis tool. After construction, the airflow direction and volume of the VZ nozzles and the set temperature of the air conditioners are adjusted based on the thermal environment measurement results from perspectives such as SET* and the results of interviews with workers. By using airflow analysis, it is possible to analyze the behavior of airflow in system configurations that are difficult to solve with simple numerical calculations, such as those involving the influence of mixed airflow between VZ nozzles in real systems. Furthermore, during heating, it is possible to analyze the behavior of airflow in system configurations where rising airflow occurs and warm air bounces off the floor surface.
[0210] In Use Case 4, the air conditioner 104, the blower 114, the surveillance camera 124A, and the measuring instrument 124B are connected to the control device 194. The control device 194 includes memory and a processor, etc. The control device 194 receives video of the target space S captured by the surveillance camera 124A and measurement values of the four thermal elements acquired by the measuring instrument 124B. The control device 194 controls the air conditioner 104 and the blower 114.
[0211] In the target space S, for example, in a factory, heat-generating elements such as industrial machinery may be placed, and in a supermarket, refrigeration equipment such as refrigerators and freezer display cases may be placed. In the case of supermarkets and offices, instead of VZ nozzles, a transport fan with a circulator or airflow function should be assumed as the blower. If the purpose is to improve the efficiency of heating and cooling, the oscillating function of the transport fan should not be used. In order to circulate air as a circulator, if the fan oscillates, only the nearby air will be disturbed and circulation will cease, so it is necessary to fix the airflow in one direction. The oscillating function should be used when using it as an airflow function. Furthermore, when using a transport fan, the operating mode, set temperature, airflow volume, and airflow direction should be set for the air conditioner, and the airflow direction and airflow volume should be set for the transport fan. In addition, the air conditioner, transport fan, and surveillance camera should be interconnected using a controller or cloud server so that they can be controlled in coordination. In particular, in the case of an office, VAV (Variable Air Volume) may be assumed. The VAV (Variable Airflow) can increase or decrease the airflow to match pre-set indoor conditions.
[0212] (Operating conditions for each device) In Use Case 4, the blower 114 blows air towards the work area in the target space S. Specifically, the control device 194 identifies the position of a person in the work area from the video acquired by the surveillance camera 124A and directs the blower 114 towards the identified person's position. In other words, the blower 114 prioritizes blowing air in the direction of the person in the target space S. As shown in Figure 12, it is preferable that the blower 114 and the surveillance camera 124A be configured as an integrated unit. This makes it possible to control the up, down, left, and right directions of the blower 114 toward the position of the person identified by the surveillance camera 124A. If the blower 114 and the surveillance camera 124A are configured independently, the direction of the blower 114 can be appropriately controlled toward the person captured by the surveillance camera 124A by converting the coordinate space of the control information for the pan / tilt control of the blower 114 and the pan / tilt control of the surveillance camera 124A using a controller or similar device. Use Case 4 is effective for heat countermeasures in summer and cold countermeasures in winter in areas with a small number of workers. Specifically, it can be envisioned as a measure against heat or cold when passing by or temporarily working in front of heat-generating industrial equipment. By linking with surveillance cameras, it is possible to detect when workers enter or leave the target area and control the supply and stop of cool or warm air, further increasing energy efficiency.
[0213] In Use Case 4, the air conditioner 104 performs either heating or cooling operation. The operation of the air conditioner 104 will be described below, separately for cooling operation and heating operation.
[0214] (Operation during cooling operation) During cooling operation, the air conditioner 104 blows cool air into the target space S via the blower 114. Also during cooling operation, the air conditioner 104 adjusts the set temperature or the airflow from the blower 114 according to the position of people in the target space S.
[0215] In detail, the control device 194 is configured as a surveillance camera 124A, consisting of a visible light camera and a thermal camera. It identifies the location of a person from the image and determines whether the person is in an area affected by solar radiation in the target space S, for example, by image recognition using a thermal camera, to determine the relationship between the person and the effects of solar radiation. Based on the determination result, the direction of the blower 114 is changed vertically and horizontally to face the location of the person. If there are multiple people, the person closest to the blower 114 is targeted, or, in the case of cooling, the person with the highest average temperature in the temperature distribution image of the person's area captured by the thermal camera is targeted. The specific implementation method for the above control is as follows: Data acquired by the thermal camera is represented as temperature distribution data, which is thermal image data. For human detection, since the area where a person is located is hotter than the background such as walls and floors, the area where a person is located can be detected by searching for areas with higher temperatures compared to the background thermal data when no person is present. In other words, the difference between the background thermal data and the thermal data where a person is located is calculated, and the area where a person is located is determined using a pre-set threshold. The temperature of a person is also determined by the average value of the temperature distribution data in the area where a person is located. For the effect of solar radiation, the effect of solar radiation is determined by comparing it with a night image where there is no effect of solar radiation. Alternatively, the effect of solar radiation can be determined simply by using a pre-set threshold to identify areas with higher temperatures than the threshold in the background thermal data, excluding people and heat sources. The monitoring area may be monitored over a wide area using multiple surveillance cameras, or it may be a configuration in which a wide-angle lens or a camera with a 360-degree rotatable shooting unit is used to capture a wide area of the monitoring area. Alternatively, a configuration may be used in which a priority area for monitoring is determined and monitored with a fixed camera. The method for determining the effects of solar radiation on people shown here is just one example; to accurately determine the effects of solar radiation, a configuration using a solar radiation sensor or a method combining it with distance sensors such as millimeter-wave sensors may also be used. If the control device 194 determines that a person is in an area affected by sunlight, it lowers the set temperature of the air conditioner 104 compared to when there is no sunlight, or increases the airflow of the air conditioner 104 and the airflow volume blown out from the blower 114 compared to when there is no sunlight. This suppresses the rise in the person's perceived temperature due to the effects of sunlight.
[0216] Similarly, the control device 194 determines by image recognition whether a person is near a heat source in the target space S. For example, if the heat source is industrial equipment, the degree of heat generated by the industrial equipment can be determined by comparing an image of the industrial equipment not operating at night with an image of the industrial equipment operating during the day. Alternatively, the effect of the heat source can be determined simply by identifying areas with temperatures higher than the threshold using a pre-set threshold for thermodata including the heat source. During cooling, if the control device 194 determines that a person is located near a heat source, it lowers the set temperature of the air conditioner 104 of the heat source compared to when the person is not located near the heat source, or increases the airflow of the air conditioner 104 and the airflow volume blown out from the blower 114 compared to when the person is not located near the heat source. This suppresses the rise in the person's perceived temperature due to the heat source.
[0217] Furthermore, the control device 194 determines whether or not a person is in the vicinity of the cooling equipment in the target space S by image recognition. The effect of the cooling equipment may also be determined by identifying areas below a predetermined threshold using thermodata that includes the area in which the cooling equipment is operating. When the control device 194 determines that a person is located near the cooling equipment during cooling, it raises the set temperature of the air conditioner 104 compared to when the person is not located near the cooling equipment, or reduces the airflow of the air conditioner 104 compared to when the person is not located near the cooling equipment, thereby reducing the airflow of the air blown out from the blower 114. This suppresses an excessive drop in the person's perceived temperature due to the cooling equipment.
[0218] (Operation during heating operation) During heating operation, the air conditioner 104 blows warm air into the target space S via the blower 114. Also during heating operation, the air conditioner 104 adjusts the set temperature or the airflow from the blower 114 according to the position of people in the target space S.
[0219] In detail, the control device 194 is configured as a thermal camera, which acts as a surveillance camera 124A. It identifies the location of a person from the image and determines whether the person is in an area affected by solar radiation in the target space S, using image recognition with the thermal camera to determine the relationship between the person and the effects of solar radiation. Based on the determination result, the direction of the blower 114 is changed vertically and horizontally to face the location of the person. If there are multiple people, the person closest to the blower 114 is targeted, or in the case of heating, the person with the lowest average temperature in the temperature distribution image of the person's area captured by the thermal camera is targeted. The specific implementation method is the same as in the case of cooling. If the control device 194 determines that a person is in an area affected by sunlight, it lowers the set temperature of the air conditioner 104 compared to when there is no sunlight, or reduces the airflow of the air conditioner 104 compared to when there is no sunlight, thereby reducing the airflow from the blower 114. This suppresses an excessive rise in the person's perceived temperature due to the effects of sunlight.
[0220] Similarly, the control device 194 determines by image recognition whether or not a person is near a heat source in the target space S. The method for implementing this determination is the same as in the cooling operation. If the control device 194 determines that a person is located near a heat source, it lowers the set temperature of the air conditioner 104 of the heat source compared to when the person is not located near the heat source, or it reduces the airflow of the air conditioner 104 and the airflow of the blower 114 compared to when the person is not located near the heat source. This suppresses an excessive rise in the person's perceived temperature due to the heat source.
[0221] Furthermore, the control device 194 determines, by image recognition, whether or not a person is near a cooling device or window in the target space S. The method for implementing this determination is the same as during cooling. If the control device 194 determines that a person is located near a cooling device or window, it raises the set temperature of the air conditioner 104 compared to when the person is not located near a cooling device or window, or increases the airflow of the air conditioner 104 and the airflow volume blown out from the blower 114 compared to when the person is not located near a cooling device or window. This suppresses the decrease in the person's perceived temperature due to the cooling device or window.
[0222] (Calculation and output of results) In Use Case 4, the calculation unit 203 calculates SET* from the start of the evaluation using the measured values of the four thermal elements in the work area where the person is located in the target space S, along with fixed values for metabolic rate and clothing amount. The calculation unit 203 then calculates the time required Δt from the start of the evaluation until SET* reaches the target value. The calculation unit 203 also calculates the power consumption of the air conditioner 104 and blower 114 during the required time Δt as power consumption H. Note that SET* may be calculated and output using the method described in the calculation and output of results for Use Cases 2 and 3. Specifically, metabolic rate and clothing amount may be variable values instead of fixed values. Specifically, metabolic rate (for example, estimating metabolic rate by sensing whether the person is thin or overweight) and clothing amount (for example, estimating clothing amount by sensing whether the person is wearing short sleeves, long sleeves, or heavy clothing) may be estimated using a thermosensor or millimeter wave sensor. Alternatively, values calculated using formulas may be used for the air temperature and airflow velocity near a person, which are generated by the wind supplied from the blower 114.
[0223] The display unit 204 uses the display 22 to display the required time Δt and power consumption H of use case 4, which is an introduction case, in a way that allows comparison with the control case. In this case, for example, the control case is used as the comparison target, in which an indoor unit is placed in place of the fan 114, which is a VZ nozzle, to air condition the entire target space S. Alternatively, the VZ nozzle that only swings in relation to the target space S may be used as the evaluation condition for the control case, and the introduction case in which the fan 114 is a VZ nozzle that can track people may be used as the fan. In this case, the number of people expected to be in the target space S may also be taken into consideration when comparing and evaluating. If there are many people at the point of airflow, swinging may increase comfort and energy efficiency, while if there are few people at the point of airflow, tracking people may increase comfort and energy efficiency. To achieve a comfortable swing for the fan 114, one method is not simply to set the swing width and swing speed, but also to divide the airflow area into multiple regions and control the airflow direction and / or airflow rate so that the average SET* of people in each airflow region reaches a target SET*. Depending on the difference in SET* between regions, airflow distribution control (airflow direction control and airflow rate control) may be performed for each region. Specifically, for regions with different levels of "warmth and coolness," the airflow distribution ratio is changed so that the difference in "warmth and coolness" is within a predetermined value. Figure 13 shows an example of a specific usage image of the blower 114 in Use Case 4. The blower 114's airflow area RV is divided into four areas RV1 to RV4, with people P11 and P12 located in two areas RV1 and RV2, and the heat-generating equipment EH located in one area RV3. The airflow area RV can be divided into any shape, size, and number of sections. Here, in areas where the heat-generating equipment EH generates a lot of internal heat, in order to avoid mixing the generated heat with the cold air blown out from the blower 114, the blower 114 is controlled so that air is not blown into the airflow area where the heat-generating equipment EH is located, and the air does not directly hit the heat-generating equipment EH. As a method for verifying the validity of the division of the airflow area RV, the installation position, airflow direction, and airflow rate of the blower 114 can be determined by airflow analysis, taking into account the placement of people P11 and P12 and heat-generating equipment EH, and initial values can be set. Then, during the trial run of the blower 114 at the installation site, the airflow direction and airflow rate can be manually adjusted. Alternatively, instead of adjustment at the installation site, the blower 114 can automatically search for and adjust the appropriate airflow direction and airflow rate by slightly deviating from the initial values of airflow direction and airflow rate so that the SET* value becomes an appropriate value. Note that if the installation position, airflow direction, and airflow rate of the blower 114 are not appropriate, in areas where there is a lot of internal heat generated by the heat-generating equipment EH, the generated heat and the cold air blown out from the blower 114 will mix, degrading comfort. Also, the closer people P11 and P12 are to the heat-generating equipment EH, the greater the influence of heat received from the heat-generating equipment EH. Therefore, the airflow to area RV1, which is close to the heat-generating equipment EH and where person P11 is located, may be increased. On the other hand, the airflow to area RV2, which is far from the heat-generating equipment EH and where person P12 is located, may be decreased. Here, the heat-generating equipment EH was the focus, but similarly, when warm air is supplied from the blower 114, an area where heat accumulates due to the cold air from the cooling equipment may be defined as one of the airflow areas RV. Furthermore, in order to improve the comfort of people, areas where heat accumulates due to gatherings of people may be directly targeted with airflow. In addition, areas where heat accumulates due to solar radiation or areas where heat accumulates due to cold air near windows may be directly targeted with airflow to promote air circulation throughout the room and improve the overall comfort of the room.
[0224] (Variation of Use Case 4) In Use Case 4, it was described that the blower 114 blows air toward the person in the target space S. However, the blower 114 may blow air toward the heat pocket generated in the heat pocket location in the target space S. In this case, the control device 194 recognizes the position of the heat pocket in the target space S and whether the heat pocket is cold air or warm air from a thermosensor or the like provided as a monitoring camera provided in the target space S.
[0225] When the heat pocket is cold air, the control device 194 causes the air conditioner 104 to perform a heating operation. Further, the control device 194 increases or decreases the set temperature of the air conditioner 104, adjusts the air volume blown from the blower 114 to increase or decrease the air volume, or increases or decreases the swing speed of the wind direction of the blower 114 according to the intensity of the heat pocket, that is, the magnitude of the temperature difference between the heat pocket and the temperature of the location other than the heat pocket in the target space S. Specifically, when the heat pocket is strong, that is, when the temperature difference between the heat pocket and other locations is large, the control device 194 increases the set temperature of the air conditioner 104, increases the air volume from the blower 114, or increases the swing speed of the blower 114. When the heat pocket is weak, that is, when the temperature difference between the heat pocket and other locations is small, the control device 194 decreases the set temperature of the air conditioner 104, decreases the air volume from the blower 114, or decreases the swing speed of the blower 114. Examples of factors that cause cold air heat pockets include those caused by cold air generated near windows in winter and cold air leaking from cold equipment. In any case, due to the building structure, the circulation of indoor air tends to be poor, and cold air heat pockets are likely to occur. The specific air blowing control method is as described above.
[0226] When the heat spot is hot air, the control device 194 causes the air conditioner 104 to perform a cooling operation. Further, the control device 194 raises or lowers the set temperature of the air conditioner 104, adjusts the air volume of the air conditioner 104, increases or decreases the air volume blown from the blower 114, or speeds up or slows down the swing of the air direction of the blower 114 according to the intensity of the heat spot. Specifically, when the heat spot is strong, that is, when the temperature difference between the heat spot and other locations is large, the control device 194 lowers the set temperature of the air conditioner 104, increases the air volume from the blower 114, or speeds up the swing of the blower 114. When the heat spot is weak, that is, when the temperature difference between the heat spot and other locations is small, the control device 194 raises the set temperature of the air conditioner 104, decreases the air volume from the blower 114, or slows down the swing of the blower 114. Examples of factors that cause hot air heat spots include hot air generated near windows in summer, hot air generated by the gathering of multiple people, and hot air generated from industrial equipment. In any case, due to the building structure, when the circulation of indoor air tends to deteriorate, hot air heat spots are likely to occur. The specific air supply control method is as described above.
[0227] (Use Case 5) Next, Use Case 5, which is an example of an introduction case, will be described.
[0228] (Arrangement of Each Device in the Target Space) First, the arrangement of each device in the target space S of Use Case 5 will be described. FIG. 14 is a diagram schematically showing the target space S in Use Case 5.
[0229] As shown in Figure 14, in Use Case 5, the target space S is equipped with an air conditioner 105, which is the indoor unit of a packaged air conditioner. The target space S is also equipped with a blower 115, which is a transport fan. The blower 115 blows air toward a ventilation opening 145 provided in the target space S. The ventilation opening 145 is an opening that connects the inside of the target space S to the outside. A ventilation device may be provided in the ventilation opening 145. The target space S is also equipped with a heat-generating element 155. Furthermore, the air conditioner 105 and the blower 115 are connected to a control device 195. The control device 195 includes memory and a processor, etc. The control device 195 controls the air conditioner 105 and the blower 115.
[0230] (Operating conditions for each device) The control device 195 controls the air conditioner 105 to perform cooling or heating operation. The control device 195 also controls the blower 115 to blow air towards the ventilation opening 145. This allows the heat from the heat-generating element 155 to be dissipated outdoors through the ventilation opening 145.
[0231] In detail, when the air conditioner 105 is operating in heating mode, the control device 195 reduces the airflow from the blower 115 or stops the blower 115 compared to when the air conditioner 105 is operating in cooling mode. This allows for efficient cooling by utilizing the heat from the heat-generating element 155 during heating mode and dissipating the heat from the heat-generating element 155 during cooling mode.
[0232] [1-3. Effects, etc.] As described above, in this embodiment, the fan introduction support system 1000 includes an acquisition unit 202 that acquires heat accumulation locations in the target space S of building BL where heat accumulation is likely to occur, a calculation unit 203 that calculates at least one of the time required Δt or power consumption H from the temperature at the start of evaluation of the heat accumulation location until the heat accumulation location reaches a reference temperature T9 for each of the following: an introduction case in which the target space S is equipped with an air conditioner and a fan, and a control case in which the target space S is equipped with an air conditioner but not a fan, and a display unit 204 that compares and outputs at least one of the time required Δt or power consumption H calculated by the calculation unit 203 between the introduction case and the control case. This makes it easier to compare the difference in the time required Δt or power consumption H for dissipating heat buildup with and without a fan. Therefore, it becomes easier for users to experience the benefits of introducing a fan. One embodiment of this invention is the use of airflow analysis and energy simulators, which makes it possible to explain the effects of introducing airflow-based equipment to customers during the equipment selection and design stages. Furthermore, by analyzing and presenting the effects based on the operational performance data of the customer's equipment using actual systems delivered to the customer's site, it becomes possible to explain the effects of introducing airflow-based equipment during operation.
[0233] As in this embodiment, the blower introduction support system 1000 may be configured to include a heat accumulation location identification unit 205 that identifies heat accumulation locations based on information about the target space S. This allows for the automatic identification of heat accumulation areas based on information about the target space S. Therefore, it reduces the effort required to identify heat accumulation areas while making it easier for users to experience the benefits of installing a fan.
[0234] As in this embodiment, in the blower introduction support system 1000, the display unit 204 may output a layout diagram I2 of the target space S for both the introduction case and the control case, and the layout diagram I2 may show the arrangement of the air conditioner and the location of heat accumulation points in the target space S for the control case, and the arrangement of the air conditioner, the arrangement of the blower, and the location of heat accumulation points in the target space S for the introduction case. This allows the placement of air conditioners and fans to be output along with a comparison of the time required Δt or power consumption H for eliminating heat buildup, with and without fans. Therefore, it becomes easier for users to visually understand the effects of introducing fans.
[0235] As in this embodiment, in the blower installation support system 1000, the calculation unit 203 calculates at least one of the required time Δt or power consumption H under evaluation conditions in which the capacity of the air conditioner in the installation case is smaller than the capacity of the air conditioner in the control case, and the display unit 204 further outputs information regarding the capacity of the air conditioner in the control case and the capacity of the air conditioner in the installation case. This allows us to compare the time required Δt or power consumption H for eliminating heat buildup when a fan is installed instead of an air conditioner, along with information about the air conditioner's capacity. Therefore, it becomes easier for users to understand the benefits of installing a fan instead of an air conditioner.
[0236] As in this embodiment, the fan introduction support system 1000 may be configured to include a display unit 204 that presents candidate arrangements of air conditioners and fans in the target space S as candidate evaluation conditions for the introduction case in the calculation unit 203. This makes it easier for users to set evaluation conditions necessary for calculating the time required Δt or power consumption H for eliminating heat buildup, simply by selecting from the presented options for the placement of air conditioners and fans. Therefore, it reduces the effort required from users while making it easier for them to experience the benefits of installing fans.
[0237] As in this embodiment, the blower introduction support system 1000 may be configured to include a display unit 204 that displays the sound power level of the operating noise generated by the operation of at least one of the blower, air conditioner in the introduction case, or air conditioner in the control case. This makes it easier to compare the difference in sound power levels with and without a fan. Therefore, it becomes easier for users to experience the benefits of introducing a fan.
[0238] As in this embodiment, the blower installation support system 1000 may have an amortization period calculation unit 206 that calculates the amortization period L of the blower in the installation case based on the installation cost of the blower in the installation case and the power consumption H of the control case and the installation case calculated by the calculation unit, and the display unit 204 further outputs the calculated amortization period L. This allows us to show users the amortization period L for the blower. Therefore, it becomes easier to alleviate users' concerns about introducing the blower.
[0239] As in this embodiment, in the blower introduction support system 1000, the calculation unit 203 may be configured to calculate at least one of the required time Δt or power consumption H by comparing an introduction case in which the blower is operated with a control case in which the air conditioner is operated, when the time it takes for heat to accumulate at a heat accumulation point in the target space S is less than or equal to a predetermined time, or when the frequency of heat accumulation is low. This allows us to calculate the time required Δt or power consumption H for eliminating heat buildup when a fan is effectively operated, for example, when the duration of heat buildup during meetings is short or the frequency of heat buildup is low. Therefore, it becomes easier for users to experience the benefits of introducing a fan.
[0240] As in this embodiment, the blower installation support system 1000 may be configured such that the acquisition unit 202 acquires information regarding the thermal insulation performance of the building BL, and the calculation unit 203 calculates at least one of the required time Δt, power consumption H, or sound power level of the operating noise in an installation case where, if the thermal insulation performance of the building BL is below a predetermined thermal insulation performance, the airflow rate of the blower is increased compared to the case where the thermal insulation performance of the building BL exceeds a predetermined thermal insulation performance. This allows for the calculation of the time required Δt, power consumption H, or sound power level required to eliminate heat buildup when a fan is effectively operated, depending on the building's thermal insulation performance. Therefore, it becomes easier for users to experience the benefits of installing a fan.
[0241] As in this embodiment, the calculation unit 203 may be configured to calculate at least one of the required time Δt or the amount of power consumed H in an implementation case in which the air conditioner is set to wind-shielding operation mode, a blower is installed on at least one of the ceiling, floor, or wall of the target space S, and the blower is made to blow air in the same direction as or opposite to the airflow generated by the air conditioner. This allows us to calculate the time Δt or power consumption H required to eliminate heat buildup when the air conditioner is set to wind-blocking mode and a fan is used effectively. Therefore, it becomes easier for users to experience the benefits of introducing a fan when the air conditioner is operating in wind-blocking mode.
[0242] As in this embodiment, the calculation unit 203 may be configured to allow setting whether or not the air conditioner performs circulation operation for at least one of the required time Δt or power consumption H for at least one of the air conditioners in either the introduction case or the control case. According to this, considering whether to perform the circulation operation by the air conditioner or not, it is possible to calculate the required time Δt or the power consumption amount H related to the elimination of the heat accumulation. Therefore, it is possible to make it easier for the user to feel the effect of introducing the blower considering whether the air conditioner performs the circulation operation or not.
[0243] As in this embodiment, the calculation unit 203 may be configured to calculate at least one of the required time Δt or the power consumption amount H in the above introduction case where a plurality of outdoor units are provided outside the target space S, and when the difference in the load factor between the plurality of outdoor units is greater than or equal to a predetermined value, the blower is made to operate to eliminate the temperature unevenness in the room. According to this, it is possible to calculate the required time Δt or the power consumption amount H related to the elimination of the heat accumulation when the blower is made to operate to eliminate the temperature unevenness according to the load factors of the plurality of outdoor units. Therefore, it is possible to make it easier for the user to feel the effect of introducing the blower when a plurality of outdoor units are provided outside the target space S. For example, the load factor of the outdoor unit may be given by the ratio of the current value of the current outdoor unit to the rated current value of the outdoor unit. Here, the outdoor unit has been focused on, but when there are a plurality of indoor units, the load factors between the indoor units can be made uniform by the blower. The load factor of the indoor unit is estimated, for example, by the difference between the set temperature and the suction temperature of each indoor unit. In this case, it can also be applied to a form in which a plurality of indoor units are housed in one air conditioner, such as a GHP or a VRF. That is, the calculation unit 203 may be configured to calculate at least one of the required time Δt or the power consumption amount H in the above introduction case where an air conditioner with a plurality of indoor units is provided in the target space S, and when the difference in the load factor between the plurality of air conditioners is greater than or equal to a predetermined value, or when a plurality of outdoor units are provided outside the target space S and the difference in the load factor between the plurality of outdoor units is greater than or equal to a predetermined value, the blower is made to operate to eliminate the temperature unevenness in the room.
[0244] As in this embodiment, the calculation unit 203 may be configured to calculate at least one of the required time Δt or the amount of power consumed H in the above-mentioned case in which a ventilation device is provided in the target space S, and outside air cooling operation can be performed by stopping the air conditioner and taking in outside air through the ventilation device, and the blower is operated while the outside air cooling operation is being performed. This allows for the calculation of the time Δt or power consumption H required to eliminate heat buildup when a fan and outside air cooling operation are combined.
