[0013] (Findings that formed the basis of this disclosure) At the time the inventors arrived at the idea of ​​this disclosure, there was a technology available that supported the formulation of plans for the configuration and specifications of air conditioning equipment to be installed in buildings. Because the air conditioning load and comfort of a building are affected by indoor humidity, it is desirable to take indoor humidity into consideration when installing air conditioning equipment. However, the inventors discovered a problem in that there are a variety of devices involved in adjusting humidity in buildings, making it difficult to formulate a plan for air conditioning equipment that includes these devices. To solve this problem, the inventors came up with the subject matter of the present disclosure. Therefore, the present disclosure provides a support method, support system, and program that can support the formulation of a plan that takes indoor humidity into consideration when formulating a plan to introduce air conditioning equipment into a building.

[0014] Hereinafter, embodiments will be described in detail with reference to the drawings. However, in some cases, more detailed explanation than necessary may be omitted. For example, detailed explanation of already well-known matters or redundant explanation of substantially the same configuration may be omitted. The accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0015] (Embodiment 1) [1-1. Information output system configuration] FIG. 1 is a diagram showing an overview of an information output system 1000. As shown in FIG.

[0016] The information output system 1000 includes a terminal device 2 and a server device 3, and provides an information provision service related to a building BL. The information provision service includes generating and outputting support information related to an air conditioning system 1 installed in the building BL. The information output system 1000 is an example of a support system.

[0017] Examples of building BL include houses, offices, warehouses, stores, factories, schools, and lodgings. In this embodiment, non-residential buildings such as commercial buildings are taken as examples of building BL. The information provision service provided by the information output system 1000 can be applied to both building BL, which is a newly constructed building, and existing building BL. In the following description, the indoor space of the building BL includes rooms used by users in the building BL, shared spaces such as corridors and halls, and other spaces, and these are collectively referred to as "rooms" or "indoor spaces."

[0018] The terminal device 2 is a PC (Personal Computer). In Fig. 1, a laptop PC is illustrated as an example of the terminal device 2, but the terminal device 2 may be a desktop PC, a tablet PC, or a smartphone.

[0019] The server device 3 is a device that processes information using devices connected to the network NW as clients. The network NW includes the Internet, a telephone network, and other communication networks. Although the server device 3 is represented by a single block in FIG. 1, this does not necessarily mean that the server device 3 is composed of a single device. The server device 3 may also be a so-called cloud server.

[0020] The target of the information provision service is a candidate for air conditioning equipment 1 that is scheduled to be installed in a newly constructed building BL. The target of the information provision service may also be a candidate for air conditioning equipment 1 that is scheduled to be installed in an existing building BL when an update of the existing air conditioning equipment is scheduled. The target of the information provision service may also be air conditioning equipment 1 that is installed in an existing building BL. In FIG. 1, the newly constructed building BL1 is indicated by a dotted line, and the existing building BL2 is indicated by a solid line.

[0021] The air conditioning equipment 1 includes an air conditioner 11, which will be described later, and further includes equipment having a function of adjusting the humidity of the indoor space of the building BL. Examples of equipment having a function of adjusting the humidity of the indoor space include a dehumidifier that dehumidifies the indoor space, a circulator that circulates air in the room, and a ventilation device that ventilates the indoor space. In this embodiment, these devices will be described as a ventilation device 15.

[0022] 2 is an explanatory diagram showing an example of a building BL to which support by the information output system 1000 is applied. When the building BL is a newly constructed building, the configuration of the building BL is assumed as shown in FIG. 2 based on the design drawings of the building BL.

[0023] The building BL shown in FIG. 2 has multiple floors FL, specifically floor FL1 with an entrance and floors FL2, FL3, and FL4 above floor FL1. The space of each floor FL constitutes one or more areas AL. For example, floor FL3 is divided into four areas AL. The other floors FL1, FL2, and FL4 may be divided into multiple areas AL like floor FL3, or the entire space of floor FL may be one area AL. Areas AL do not have to be spaces separated by walls or the like; for example, one space may include multiple areas AL. Also, shared spaces such as corridors may be considered one area AL.

[0024] The air conditioner 11 (air conditioning device) targeted by the information provision service is a package air conditioner installed in the building BL, such as an office / store air conditioner, a multi-air conditioner for a building, or a gas peat pump air conditioner. The air conditioner 11 may be configured such that one outdoor unit houses one indoor unit, or such that one outdoor unit houses multiple indoor units. The air conditioner 11 may also be configured to include central air conditioning realized by an absorption chiller or the like.

[0025] As described above, the air conditioning equipment 1 includes an air conditioner 11 and a ventilator 15. For example, if one air conditioner 11 is provided on each of floors FL1 to FL4 of the building BL, the air conditioning equipment 1 will have four air conditioners 11. The air conditioner 11 is configured by connecting one or more outdoor units 12 and multiple indoor units 13 via a refrigerant circuit 14. The indoor units 13 are installed, for example, in each area AL of the floor FL, and each indoor unit 13 performs cooling and heating for one area AL. A similar configuration can be used on the other floors FL. The indoor units 13 may be configured to be able to individually switch between cooling and heating, or all of the indoor units 13 may be configured to perform the same operation of either cooling or heating.

[0026] There is no limit to the number or manner in which ventilation devices 15 are installed in building BL, and one may be installed in each area AL. In the example of Fig. 2, a ventilation device 15 is installed in one area AL on floor FL3. This is just one example, and for example, humidity control in multiple areas AL may be performed by one ventilation device 15, or humidity control in one area AL may be performed by multiple ventilation devices 15.

[0027] The air conditioner 11 is capable of performing evaporation temperature control. Examples of how evaporation temperature control can be achieved using hardware include automatic evaporation temperature control in accordance with the air conditioning load, and manual setting of the evaporation temperature control setting. These examples will be described below.

[0028] When evaporating temperature control is performed automatically according to the air conditioning load, the air conditioner 11 estimates the air conditioning load from the difference between the indoor temperature of the area AL conditioned by the indoor unit 13 and the set temperature, and calculates the fan airflow rate of the indoor unit 13 and the temperature of the heat exchanger of the indoor unit 13, i.e., the target value of the evaporating temperature. The outdoor unit 12 sets the lowest evaporating temperature among the target values ​​of the evaporating temperatures of the indoor units 13 connected to the outdoor unit 12 by the refrigerant circuit 14 as the target value.

[0029] The air conditioning load can be calculated not only by taking into account the sensible heat load based on temperature, but also by taking into account the latent heat load based on humidity, for example. In this case, a target humidity for area AL is set using a ventilation system with humidity control functionality, and the magnitude of the latent heat load is defined based on the difference between the target humidity and the indoor humidity of area AL. The indoor temperature can be determined using a value detected by any of the following sensors: an intake temperature sensor in indoor unit 13, a floor temperature sensor in indoor unit 13, or a temperature sensor on a remote control attached to indoor unit 13. The humidity can be determined using a value detected by any of the following sensors: a humidity sensor in indoor unit 13 or a humidity sensor on the remote control. Note that the evaporative temperature control in air conditioner 11 may be performed based on a discomfort index, which is an index of both temperature and humidity.

[0030] In an embodiment in which the set value for evaporation temperature control is set manually, each indoor unit 13 adjusts the expansion valve opening so as to maintain the indoor temperature at the set temperature. The outdoor unit 12 calculates the target value for the compressor rotation speed to maintain a constant evaporation temperature. In the manual mode, the evaporation temperature of the outdoor unit 12 is not controlled according to the air conditioning load of the indoor unit 13, so an offset value is applied to the evaporation temperature of the outdoor unit 12.

[0031] The evaporation temperature offset value of the outdoor unit 12 can be set in multiple stages. The outdoor unit 12 calculates a target value for the compressor rotation speed based on the offset evaporation temperature and controls the compressor. The higher the evaporation temperature offset temperature, the greater the improvement in COP (Coefficient of Performance) characteristics. Examples of evaporation temperature offset values ​​are as follows: Level (no correction): Offset value example 0℃ Evaporation temperature (upper limit) control value ±0℃ Level (Lv1): Offset value example +2°C Evaporation temperature (upper limit) control value +2°C Level (Lv2): Offset value example +4°C Evaporation temperature (upper limit) control value +4°C Level (Lv3): Offset value example +6°C Evaporation temperature (upper limit) control value +6°C For example, when the offset value of the outdoor unit 12 is manually set to level Lv1, the upper limit of the evaporation temperature used to control the compressor of the outdoor unit 12 is set to a value that is 2°C higher. This increases the evaporation temperature of the outdoor unit 12, thereby improving the COP characteristics.

[0032] When the air conditioner 11 performs evaporative temperature control, the compressor rotation speed of the outdoor unit 12 is suppressed, reducing the air conditioning load processing capacity. For this reason, it may be appropriate not to perform evaporative temperature control when the area AL is in a high-humidity state. Specific examples of situations in which automatic evaporative temperature control is inappropriate include sudden changes in weather conditions in the area where the building BL is located, such as during seasonal changes or extreme heat, and sudden changes in the air conditioning load due to an increase or decrease in the number of people in a waiting room or elevator hall, making it difficult for the evaporative temperature control to keep up with the changes in air conditioning load, making it impossible to set an appropriate evaporative temperature value. Examples of situations in which manual evaporative temperature setting is inappropriate include the above cases, as well as when it is impossible to set an appropriate offset value that can handle the air conditioning load.

[0033] In a typical air conditioner 11 where the evaporation temperature control setting value is not manually set, the evaporation temperature remains constant even under low load, and the compressor rotation speed is high, which can easily result in unnecessary starting and stopping. Also, as mentioned above, in some air conditioners, it is possible to set the evaporation temperature in the outdoor unit 12, and for example, it is possible to set the evaporation temperature in multiple stages.

[0034] On the other hand, when evaporation temperature control is executable, the air conditioner 11 estimates the air conditioning load from the difference between the indoor temperature of area AL and the set temperature, and calculates target values ​​for the fan airflow rate of the indoor unit 13 and the temperature of the heat exchanger of the indoor unit 13. The outdoor unit 12 sets the lowest evaporation temperature among the target evaporation temperatures of each indoor unit 13 as the target value. The outdoor unit 12 then calculates a target value for the compressor rotation speed and controls the compressor of the outdoor unit 12. Note that, in addition to a configuration in which the indoor unit with the lowest evaporation temperature is selected and the evaporation temperature of that indoor unit is used as the control target for evaporation temperature control, evaporation temperature control may also be performed using the compressor suction temperature as the evaporation temperature.

[0035] By controlling the evaporation temperature, the air conditioner 11 can control the rotation speed of the compressor of the outdoor unit 12 according to the air conditioning load, thereby suppressing unnecessary starting and stopping of the outdoor unit 12 in the low load range, thereby improving the COP. However, due to the high insulation of buildings in recent years, the room temperature in offices and other places can become high even in winter, and air conditioning may be required. Also, because humidity is low in winter, humidification may be performed, which may result in excessive humidification. In this case, the conditions are the same as in summer, and evaporative temperature control is effective. In addition, if the high-pressure pressure can be lowered when the outdoor temperature is low during heating operation of the air conditioner 11, further efficiency improvements are expected. In other words, controlling the condensing temperature low during heating increases the outdoor unit's operating efficiency. However, in winter, when humidity is low and sensible heat processing is the primary method, setting the condensing temperature unnecessarily low may result in insufficient sensible heat processing. However, the condensing temperature may be lowered by reducing the height difference between the outdoor unit 12 and the indoor unit 13 and the piping length of the refrigerant circuit 14. For example, lowering the lower limit of the high-pressure pressure (condensing temperature) by installing the outdoor unit 12 and the indoor unit 13 on the same floor would contribute to improving the operating efficiency of the air conditioner 11. It may also be recommended to review the condensing temperature from a design perspective, in addition to the evaporation temperature during cooling.

[0036] Furthermore, as will be described later, when area AL is dehumidified using a humidity control device during cooling operation of the air conditioner 11, the latent heat load is reduced and the air conditioner 11 only needs to focus on sensible heat processing, making it possible to operate the air conditioner 11 with higher efficiency.

[0037] The ventilation device 15 is a device with a humidity control function that adjusts the humidity in the area AL. The humidity control function is sufficient as long as it at least reduces the humidity of the air in the area AL. The ventilation device 15 may be a device with only a ventilation function, and the ventilation mode may be any of type 1 ventilation, type 2 ventilation, and type 3 ventilation. The ventilation device 15 may also be a circulator. For example, the ventilation device 15 is a ventilation fan that exhausts air from the area AL to the outside and introduces outside air into the area AL, or a ventilation device that both introduces outside air into the area AL and exhausts inside air. In general, doors are opened and closed frequently inside a store, and the ventilation volume is high due to the influence of a range hood. To prevent dust from entering the store, the in-store ventilation may be configured to positively pressurize the area AL.

[0038] In addition, the ventilation device 15 may be a device having a ventilation function and a heat exchange function, such as a total heat exchanger (total heat exchange ventilator, ERV: Energy Recovery Ventilator) that exchanges heat between air supplied from outdoors to indoors and air exhausted from indoors to outdoors.

[0039] The ventilation device 15 may also be a device that has the function of adjusting the humidity of the air in the area AL, such as by absorbing moisture, dehumidifying, or humidifying. For example, the ventilation device 15 may be a humidity control device that has a desiccant rotor and performs at least one of dehumidifying and humidifying the air in the area AL. This humidity control device absorbs and releases moisture by exposing a desiccant rotor containing a moisture absorbent to air of different relative humidity. This type of ventilation device 15 dehumidifies the air inside the area AL using the desiccant rotor and causes the desiccant rotor to release moisture using air outside the area AL. The ventilation device 15 may also be configured to dehumidify the air introduced into the area AL using the desiccant rotor and cause the desiccant rotor to release moisture using air exhausted from the area AL.

[0040] Furthermore, the ventilation device 15 may be a humidity-controlling outdoor air conditioner having a humidity control function using a direct expansion coil in an outdoor air treatment package that introduces outdoor air into the area AL. Alternatively, the ventilation device 15 may be a humidity-controlling total heat exchanger (humidity-controlling ERV) having a humidity control function using a desiccant rotor and a function of exchanging heat between the inside air exhausted from the area AL and the outdoor air introduced into the area AL.

[0041] Ventilation device 15 may also be a CO2 sensor-linked ventilation device that includes a CO2 sensor that detects the CO2 concentration in the air in area AL and autonomously starts and stops operation according to the value detected by the CO2 sensor. Ventilation device 15 may also be a humidity sensor-linked ventilation device that includes a humidity sensor that detects the relative humidity in area AL and autonomously starts and stops operation according to the value detected by the humidity sensor. The ventilation function of the humidity sensor-linked ventilation device may employ any of the above-described ventilation device, total heat exchanger, humidity control outdoor air conditioner, and humidity control total heat exchanger.

[0042] Furthermore, the ventilation device 15 may be an air conditioner with an outside air processing function that is integrated into the air conditioner 11 and performs air conditioning of the area AL by the indoor unit 13 and ventilation inside and outside the area AL.

[0043] As such, the types of ventilation device 15 include a ventilation device, a total heat exchanger, a humidity control outdoor air conditioner, a humidity control total heat exchanger, a ventilation device with a CO2 sensor, a total heat exchanger with a CO2 sensor, a humidity sensor-linked ventilation device, an air conditioner with an outside air processing function, and a circulator. The present disclosure can be applied to any of these ventilation devices 15.

[0044] The selection of which model of ventilation device 15 to use is not limited to the initial cost, running cost, and thermal environment, which will be described later. As will be described below, each type of ventilation device 15 has its advantages and disadvantages. Therefore, information regarding the advantages and disadvantages of each model of ventilation device 15 may be included in the support data 223 and output together with information recommending the introduction of the ventilation device 15, so that the ventilation device 15 can be selected taking into account the various advantages and disadvantages. For example, the recommended models and types of ventilation devices 15 may be clearly displayed on the information display screen 31, which will be described later. In this case, information indicating the advantages and / or disadvantages of each model or type of ventilation device 15 may be displayed together with the models and types of ventilation devices 15. Furthermore, the advantages and disadvantages of each model of ventilation device 15 may be reflected in the simulation conditions so as to be clearly indicated.

[0045] As specific examples of the advantages and disadvantages of the ventilation device 15, we will list the advantages and disadvantages when comparing a simple ventilation device that exhausts and takes in air (hereinafter referred to as the ventilation device), a total heat exchanger, a humidity-control total heat exchanger, and a humidity-control outdoor air conditioner.

[0046] The advantages of ventilation systems are that they are inexpensive and require little or no installation space. Furthermore, ventilation can be expected to have an energy-saving effect due to the mixed gain (the indoor load is cooling and the outdoor air load is heating, canceling out each other). The disadvantage is that untreated outdoor air is blown directly into the AL area, which can cause issues with the comfort of the AL area. Also, there are limitations to humidification in winter.

[0047] The advantage of a total heat exchanger is that it can adjust the temperature of the outside air introduced into the AL area by exchanging heat with the indoor exhaust air, thereby reducing the outside air load associated with ventilation. Energy savings can also be expected due to the mixing gain. Furthermore, adopting bypass control for the total heat exchanger is expected to further increase the energy savings. Total heat exchangers also improve the comfort of the AL area compared to direct introduction of outside air through a ventilation system. The disadvantage is that the temperature of the air blown into the AL area is often lower than the room temperature, which creates comfort issues in the AL area. They are also unsuitable for use in spaces with large exhaust volumes, such as restrooms. While they have a dehumidifying effect in the summer, their dehumidifying capacity is low and is affected by weather conditions, so their dehumidifying effect is, so to speak, haphazard. Furthermore, they have limited humidifying capacity in the winter.

[0048] The advantage of a humidity-control total heat exchanger is that in addition to the benefits of a total heat exchanger, the direct expansion coil improves the comfort of the area AL and can be expected to humidify in winter. The disadvantage is that it is not suitable for use in spaces with large exhaust volumes such as toilets. Although it has a dehumidifying effect in summer, its dehumidifying capacity is low and it is a matter of course.

[0049] The advantage of humidity control outdoor air conditioners is that they can be used in places with large exhaust volumes, such as toilets, while maintaining comfort. They can also be expected to humidify in the winter. In hot and humid regions, dehumidification is a challenge due to the high humidity of the outside air, so humidity control outdoor air conditioners with desiccant units are used. Outdoor air conditioners are sometimes used for ventilation in spaces that require large-scale ventilation, such as hospitals. The disadvantage is that they do not exchange heat with indoor exhaust air, so they cannot reduce the load on the outside air.

[0050] When installing ventilation equipment that complies with the Building Management Act (Act on Ensuring Sanitary Environments in Buildings), it is appropriate to use an outdoor air conditioner or a total heat exchanger with a direct expansion coil to maintain indoor humidity. Also, when the air conditioner 11 is operating in cooling mode, if the amount of latent heat is large, latent heat separation air conditioning can be achieved by controlling the indoor humidity with a total heat exchanger with a direct expansion coil or a humidity control outdoor air conditioner. In other words, the air conditioner 11 can focus on sensible heat treatment, which can increase the evaporation temperature of the air conditioner 11 and contribute to energy savings.

[0051] [1-2. Overview of the operation of the information output system] Here, an overview of the operation of the information output system 1000 will be described. The building BL that is the target of the service provided by the information output system 1000 is an existing building or a newly constructed building. If the building BL is an existing building, the information output system 1000 generates and outputs support data 223 that includes information about an air conditioning system 1 that will be installed in the already constructed building BL to replace the existing air conditioning system. If the building BL is a newly constructed building, the information output system 1000 generates and outputs support data 223 that includes information about an air conditioning system 1 that will be installed in the building BL that is currently under construction or is scheduled to be constructed.

[0052] The selection of the air conditioning equipment 1 is carried out in the following procedure of steps (1) to (3). Steps (1) to (3) may be executed by a device not included in the information output system 1000, or may be executed by the terminal device 2 or the server device 3.

[0053] Stage (1): A tentative model selection is made for the air conditioner 11 and ventilation equipment 15 to be installed in building BL. In the tentative model selection, the heat load of area AL of building BL is calculated, and an air conditioner 11 is selected according to the heat load. In addition, a ventilation equipment 15 is selected according to the area and use of area AL. The heat load calculation method used here may be a heat load calculation tool based on building equipment design standards, an energy simulator, or the like.

[0054] Specifically, first, calculation conditions such as the wall conditions of building BL (materials and thicknesses of exterior walls, interior walls, floors, roofs, and windows, and heat transmission coefficient), outdoor temperature and humidity, solar radiation load, and indoor internal load (heat generated by people, heat generated by equipment such as OA outlets, and heat generated by lighting) are input. Next, the wall load is calculated based on the indoor and outdoor temperature conditions of each area AL of building BL.

[0055] Furthermore, the ventilation volume required for each area AL is calculated based on conditions such as the area of ​​each area AL and the number of people entering and exiting the area AL, and a ventilation device 15 that matches the calculated ventilation volume for each area AL is selected.

[0056] Here, the required ventilation volume for area AL can be calculated by, for example, multiplying the floor area of ​​area AL by a predetermined coefficient and dividing the result by the occupied area per person. In addition, the ventilation rate may be determined based on the volume of area AL and the ventilation frequency required to prevent sick house syndrome.

[0057] Next, a model of ventilation device 15 with the required ventilation capacity is determined based on the ventilation volume and static pressure of area AL. The capacity of the selected ventilation device 15 is also determined so that the efficiency of the selected ventilation device 15 is equal to or greater than the efficiency assumed during the design of building BL. A model of ventilation device 15 is selected based on the determined capacity, and the model of ventilation device 15 is determined again as necessary. The outdoor air load is then recalculated based on the heat exchange efficiency and equipment capacity of the ventilation device 15. Then, taking into account the reduction in outdoor air load due to the installation of the ventilation device 15 and the heat generation from the equipment installed indoors in area AL, the thermal load for selecting an air conditioner 11 is calculated based on the wall load and outdoor air load of area AL.

[0058] Next, the model of the air conditioner 11 is selected, for example, using catalog data for the air conditioner 11. That is, first, the models of the outdoor units 12 and indoor units 13 of each system of the air conditioner 11 and the indoor units 13 of each area AL are selected. An air conditioner 11 system is a structural unit consisting of one outdoor unit 12 and the indoor units 13 connected to this outdoor unit 12 via a refrigerant circuit 14. As the indoor unit 13, a device with a capacity appropriate for the heat load of the area AL, specifically, a device with a capacity equal to or greater than the heat load of the area AL, is selected. Next, an outdoor unit 12 with a capacity equal to or greater than the total cooling and heating capacity of the indoor units 13 in the system is tentatively selected. Here, the capacities of the outdoor unit 12 and the indoor units 13 are corrected. Correction items include an indoor unit 13 suction temperature correction, an outdoor unit 12 suction temperature correction, a defrost correction, and a correction based on the refrigerant piping length of the refrigerant circuit 14 and the difference in elevation between the inside and outside of the refrigerant piping. Additionally, a margin value for equipment capacity correction may be set by the designer selecting the air conditioning equipment 1. After that, the total capacity of the corrected indoor units 13 in the system is calculated, and if the corrected capacity of the outdoor units 12 is equal to or greater than the total capacity of the indoor units 13, the provisional selection is completed, but if it is less than the total capacity of the indoor units 13, the outdoor units 12 are reselected.

[0059] Step (2): Candidates for the ventilation devices 15 are selected from the multiple ventilation devices 15 selected in the tentative model selection. The candidates for the ventilation devices 15 are selected from various types of ventilation devices, such as devices that exhaust indoor air and introduce outside air, and ventilation devices with heat exchange functions, as described above.

[0060] Step (3): The heat load when the ventilation device 15 selected in step (2) above is installed in building BL is recalculated, and the air conditioner 11 and ventilation device 15 are reselected according to the calculated heat load. Specifically, a trial calculation is made of the effect of downsizing the air conditioner 11 to a simpler air conditioner by introducing a high-performance ventilation device 15. The method involves first using indoor and outdoor temperature and humidity data for the area where building BL is located to determine the outdoor air load (raw outdoor air) caused by the ventilation device 15 using the air enthalpy method, and then calculating the amount of outdoor air load reduction taking into account the outdoor air load reduction effect of the ventilation device 15. The air enthalpy method is a method for determining the air conditioning load, and the outdoor air load (raw outdoor air) without heat exchange is determined using the following formula (A): Air specific gravity × air conditioner air volume × enthalpy difference between indoors and outdoors (A) The enthalpy can be calculated from the temperature and humidity. For example, if the ventilation device 15 is a total heat exchange ventilation device, the reduction in the outdoor air load can be calculated from the heat exchange efficiency (enthalpy) specified in the ventilation device 15 specifications (for example, 70%). The outdoor air load with heat exchange is calculated using the following formula (B). Outdoor air load without heat exchange × (1 - enthalpy heat exchange efficiency) (B) Therefore, the reduction in the outdoor air load can be calculated by {(outdoor air load without heat exchange) - (outdoor air load with heat exchange)}.

[0061] The power savings from installing a total heat exchange ventilation system can be calculated by dividing the outdoor air load by the air conditioner's COP. Therefore, the electricity bill savings can be calculated by multiplying the power savings by the operating time and the electricity cost. Furthermore, the time to recover the investment in a total heat exchange ventilation system can be calculated by dividing the annual energy savings by the purchase price of the total heat exchange ventilation system - the purchase price of the ventilation system (exhaust fan).

[0062] Furthermore, for example, if the ventilation system 15 is equipped with a CO2 sensor or humidity sensor, the reduction in outdoor air load (e.g., a 30% reduction) is estimated based on the results of actual evaluations of existing buildings similar to building BL. For example, if the ventilation system 15 is a humidity control outdoor unit, the humidity setting of the humidity control outdoor unit is assumed (e.g., 50% indoor humidity), and the reduced outdoor air load after humidity control can be calculated using the air enthalpy method, as with the total heat exchange ventilation system described above. The effect of downsizing the air conditioner specifications can then be estimated using the same procedure as above. Based on the capacity of the air conditioner 11 selected in step (1), the amount of reduction in outdoor air load is reduced, and consideration is given to whether it is possible to select a model with a lower capacity for the air conditioner 11. If downsizing the air conditioner 11 is possible, catalog data for the air conditioner 11 is used to reselect an air conditioner 11 that matches the reduced capacity.

[0063] The terminal device 2 obtains information regarding the air conditioning equipment 1 including the air conditioner 11 and ventilator 15 selected by the above procedure, such as the initial cost (installation cost) of the air conditioning equipment 1, simulation results for the temperature and humidity of the area AL, an evaluation of the area AL, and the amount of power consumption of the air conditioner 11. The terminal device 2 generates and outputs support data 223 including this information.

[0064] After the air conditioner 11 and ventilation device 15 have been selected, the requester P2 provides basic data D1 including information about the selected air conditioner 11 and ventilation device 15 to the operator P1 who operates the terminal device 2. As will be described later, the basic data D1 includes information about the building BL, information about the area where the building BL is located, information about the use of the area AL of the building BL and information about the equipment installed in the area AL, information about the operating time and set temperature of the air conditioning equipment 1, etc.

[0065] An operator P1 inputs basic data D1 into a terminal device 2. Furthermore, if the terminal device 2 is capable of acquiring the basic data D1 from the server device 3, the operator P1 operates the terminal device 2 to acquire the basic data D1. The terminal device 2 uses the basic data D1 to execute an information output process for an information provision service.

[0066] When requested by the selection requester P2, the operator P1 uses the terminal device 2 to output support information for the selected air conditioning equipment 1. Here, the operator P1 may be a person who selects the air conditioning equipment 1, a person who manages the air conditioning equipment 1, or a person who provides consulting on the air conditioning equipment 1. The operator P1 may also be a person who constructed or designed the building BL. The selection requester P2 may be, for example, the owner of the building BL or a person who has been requested by the owner to manage the building BL.

[0067] Based on the basic data D1, the terminal device 2 calculates the initial cost of the air conditioning equipment 1 including the air conditioners 11 and the ventilation devices 15. The initial cost is calculated, for example, as the sum of the price obtained by multiplying the unit price of the air conditioners 11 by the number of units and the price obtained by multiplying the unit price of the ventilation devices 15 by the number of units.

[0068] Furthermore, the terminal device 2 uses an energy simulator to calculate the running costs of the air conditioning equipment 1 and evaluate the temperature and humidity of the target area AL, discomfort index (evaluation of comfort), PMV (Predicted Mean Vote), etc. For example, the terminal device 2 uses an energy simulator to generate an air conditioner model, which is a simulation model of the air conditioning equipment 1, and a building model, which is a simulation model of the building BL. The terminal device 2 calculates the annual power consumption using the air conditioner model. Here, the terminal device 2 may determine the annual maximum demand value of the air conditioning equipment 1 and calculate the electricity fee for the air conditioning equipment 1 on the assumption that the building BL receives high-voltage bulk power.

[0069] Furthermore, the terminal device 2 simulates the temperature, humidity, discomfort index, etc. of the area AL using the building model. Furthermore, the terminal device 2 evaluates whether or not condensation will occur on the walls of the area AL, which is prone to high humidity, such as the area AL used as a store. Because condensation can cause mold, condensation is a problem in facilities that require hygiene measures, such as stores that handle food, food factories, and cafeterias, and it is conceivable that the evaluation of condensation occurrence will be applied to these facilities.

[0070] [1-3. Terminal Device Configuration] FIG. 3 is a block diagram of the terminal device 2 according to the first embodiment. As shown in FIG. 3, the terminal device 2 includes a control device 20, a communication unit 21, a display 22, and an input unit 23.

[0071] The control device 20 is a device that controls each part of the terminal device 2. The control device 20 includes a processor 200 such as a CPU (Central Processing Unit) or an MPU (Micro Processor Unit), a memory 220, and an interface circuit. Note that other devices and sensors included in the terminal device 2 are connected to this interface circuit.

[0072] The memory 220 is a memory that stores programs and data. The memory 220 stores a program 221, simulation model data 222, and assistance data 223. The memory 220 stores, for example, basic data D1 acquired by the terminal device 2 as data to be processed by the processor 200. The memory 220 has a non-volatile storage area. The memory 220 also has a volatile storage area and constitutes a work area for the processor 200. The memory 220 is constituted, for example, by a ROM (Read Only Memory) or a RAM (Random Access Memory).

[0073] The processor 200 includes, as functional units, an acquisition unit 201, a determination unit 202, an estimation unit 203, an information generation unit 204, an output unit 205, and a simulator 210. These functional units are realized by the processor 200 executing a program 221.

[0074] The acquisition unit 201 acquires the basic data D1 used to generate the assistance data 223 and stores it in the memory 220. The determination unit 202 determines whether an area AL of the building BL to be processed is prone to high humidity based on the basic data D1. The determination unit 202 makes a determination for each area AL of the building BL, or for one or more areas AL designated in advance.

[0075] The estimation unit 203 estimates, for example, the power consumption of the air conditioner 11, the capacity of the air conditioner 11, the power consumption of the ventilation device 15, the room temperature and humidity of the area AL in which the air conditioner 11 is installed, etc., based on the basic data D1. The estimation unit 203 makes the estimation by having the simulator 210 execute a simulation as necessary.

[0076] The information generator 204 generates assistance data 223 including the determination result by the determiner 202 and the estimation result by the estimator 203 .

[0077] The output unit 205 outputs the assistance data 223. There are no limitations on the manner of output by the output unit 205. For example, the output unit 205 displays the contents of the assistance data 223 on the display 22. As one form of output, the output unit 205 may also transmit the assistance data 223 to a device other than the terminal device 2. As another form of output, the output unit 205 may also cause a printer to print the assistance data 223.

[0078] The simulator 210 uses an energy simulator program to create a simulation model 211 based on the simulation model data 222. The simulator 210 executes a simulation by providing parameters included in the basic data D1 to the simulation model 211, and obtains the execution results. The simulator 210 can generate a simulation model 211 according to the type and content of the simulation to be executed, and can also create multiple simulation models 211.

[0079] For example, a simulation model such as EnergyPlus, TRNSYS, or BEST is used as the simulation model 211. The simulation model 211 may be configured such that a plurality of models are configured as one simulation model and one simulation is executed.

[0080] The simulation model 211 includes a building model, a weather model, a solar radiation model, an air conditioner model, a ventilation equipment model, and an operation model of air conditioning and ventilation. A building model is defined by the structural information of the building, such as the exterior walls, floors, roofs, and interior walls of the building BL. The structural information includes, for example, material, thickness, and heat transmittance. The information used to define the building model is obtained, for example, from the design drawings of the building BL provided by the designer or contractor who designed the building BL. If the building BL is an existing building, the information used to define the building model is obtained from the design drawings and management drawings of the building BL provided by the manager or owner of the building BL.

[0081] The weather model and solar radiation model are defined by meteorological information such as temperature, humidity, and solar radiation in the area where building BL is located. The weather model simulates the outside temperature of building BL. The solar radiation model simulates the effect of solar radiation on building BL. The weather data used in the weather model and solar radiation model is data provided by organizations and companies that provide weather information, such as extended AMeDAS weather data. Furthermore, if building BL is an existing building, sensors are installed in building BL, and the detected values ​​of these sensors can be obtained, the detected values ​​of these sensors can be used in either or both of the weather model and solar radiation model. For example, the detected values ​​of an outside air temperature sensor and solar radiation sensor installed outside building BL, and temperature and humidity sensors installed inside building BL, etc., may be used in the weather model and solar radiation model.

[0082] The air conditioner model is a model that defines the equipment operation of the air conditioner 11. The air conditioner model is defined by the operation mode (cooling, heating), set temperature, air volume, operation period, operation time, rated COP, rated power consumption, etc. of the air conditioner 11. The air conditioner model executes an energy simulation of the air conditioner 11, and the amount of power consumption of the air conditioner 11, etc. are obtained from the simulation results.

[0083] The ventilation equipment model is a model that defines the equipment operation of the ventilation device 15. The ventilation equipment model is defined by information such as the operation mode, rated airflow, operation period, and operation time of the ventilation device 15. As described above, the ventilation equipment 15 includes a ventilation device, a total heat exchanger, a humidity control outdoor conditioner, a humidity control total heat exchanger, a ventilation device with a CO2 sensor, a total heat exchanger with a CO2 sensor, a humidity sensor-linked ventilation device, an air conditioner with an outdoor air processing function, and a circulator. The operation mode of the ventilation equipment 15 is defined according to the type of ventilation equipment 15. For example, the ventilation equipment model for a humidity control outdoor conditioner, a humidity control total heat exchanger, and an air conditioner with an outdoor air processing function defines the set temperature, set humidity, dehumidification capacity, etc. The ventilation equipment model performs an energy simulation, and the power consumption of the ventilation equipment 15, etc., are obtained from the simulation results.

[0084] The operation model included in the simulation model 211 performs a simulation of the operation of building BL. The operation model calculates the heat generation due to increases or decreases in the number of people, the heat generation due to lighting, the heat generation due to equipment, and the heat generation due to the introduction of outside air through ventilation. The operation model may include, for example, a human body heat generation model, a lighting equipment heat generation model, and a heat generation model for other equipment, or may be an operation model that integrates these. It may also include a model that calculates the heat generation due to the introduction of outside air. The human body heat generation model is defined based on the number of people (e.g., determined through interviews with the client or the number of seats), a reference value for human body heat generation per person, a human body heat generation ratio schedule, etc., and calculates the heat generation of people in area AL. It is desirable that the human body heat generation model be able to calculate the sensible heat component and the latent heat component separately. The lighting equipment heat generation model is defined based on the type of lighting equipment, the number of lighting equipment, the rated power of the lighting equipment, the lighting heat generation ratio schedule, etc., and calculates the heat generation of lighting devices in area AL. The equipment heat generation model is defined based on the number and power consumption of equipment such as office automation equipment, the equipment heat generation ratio schedule, etc., and calculates the heat generation of equipment in area AL. The human heat generation ratio schedule, lighting heat generation ratio schedule, and equipment heat generation ratio schedule can be based on the default values ​​of WEBPRO, an energy consumption performance calculation program (non-residential version) provided by the Building Research Institute, a national research and development agency. For example, the default values ​​of WEBPRO, Japan's energy conservation standard, specify values ​​for each room, such as the cooling season set temperature, intermediate season set temperature, heating season set temperature, air conditioning and ventilation operation period and time slot, lighting heat generation, human heat generation, equipment heat generation, number of occupants, and amount of fresh outdoor air intake. Furthermore, if the building BL is an existing building, the power consumption of lighting equipment and other equipment can be calculated from the actual power consumption of the building BL (measurements of equipment power, rated power of installed equipment, and number of installed equipment). Similarly, the human heat generation ratio schedule, lighting heat generation ratio schedule, and equipment heat generation ratio schedule can be calculated from the usage history of the existing building BL and applied to the human heat generation model, lighting equipment heat generation model, and other equipment heat generation model. Furthermore, the model of the heat load of area AL due to outdoor air intake can be based on the default ventilation schedule of WEBPRO, for example.

[0085] Furthermore, if the building BL is an existing building, a human body heat generation ratio schedule, a lighting heat generation ratio schedule, and an equipment heat generation ratio schedule may be created using power history analysis based on the actual measured values ​​of the power consumption of the building BL. In this case, for the existing building BL, the start time and end time of use, number of users, entry and exit history, etc. of the entire building BL or each area AL may be used, and changes in occupancy ratios by time period may be estimated from this information.

[0086] Here, we will show an example of how to create an operation model by analyzing power history. The steps will be carried out in the order of A to E. A. Assume that power is measured at the distribution board in the room (area AL) being evaluated. Also, assume that individual measurements are not taken for each piece of equipment (e.g., air conditioning, lighting, OA outlets, etc.). B. Obtain the monthly power change using the hourly monthly average value, and obtain the power distribution for weekdays and holidays. C. Determine the minimum power consumption on holidays and use it as the base power consumption. Determine the target month (e.g., July or August, when air conditioning utilization rates are high) and carry out steps D and E below. D. Subtract the base power from the weekday power distribution. From this result, extract the power of indoor units, lighting, and equipment that affect people's behavior. Normalize by the maximum value to create a personnel distribution. E. The lighting power distribution is calculated by multiplying the lighting rated power by the personnel distribution, and the load factor of the equipment is calculated from the difference with the power of the indoor unit, lighting, and equipment mentioned above.

[0087] The decision on whether to use power history analysis may be made based on the man-hours required for power measurement and analysis and the required accuracy of the simulation model. The human body heat generation ratio schedule may be created based on entrance / exit history, CO2 generation history, and indoor motion sensor history. The lighting heat generation ratio schedule and equipment heat generation ratio schedule may also be derived from lighting and equipment operation history.

[0088] Furthermore, the simulator 210 generates a simulation model 211 according to the intended use of the building BL and the area AL. For example, a building model, a weather model, a solar radiation model, a human body heat generation model, a heat generation model of lighting equipment, and equipment models of the air conditioner 11 and the ventilation device 15 are generated in common for various types of building BL. If the building BL is used as an office, the simulator 210 generates a heat generation model of the office automation equipment and a ventilation equipment model of the ventilation device 15, which is a total heat exchanger. Furthermore, for example, if building BL includes area AL used as a store, simulation model 211 includes a heat generation model of kitchen equipment, a ventilation equipment model of ventilation device 15 which is a ventilation fan, and a ventilation model of ventilation device 15 which is a range hood. The heat generation model of kitchen equipment includes a heat generation model of sensible heat emitted by kitchen equipment and a generation model of latent heat due to steam from the kitchen equipment. Furthermore, for example, if building BL includes area AL used as a restaurant, simulation model 211 includes a heat generation model of kitchen equipment, a heat generation model of water heater, a ventilation equipment model of ventilation device 15 which is a ventilation fan, and a ventilation model of ventilation device 15 which is a range hood. The heat generation model of water heater, like the heat generation model of kitchen equipment, includes a heat generation model of sensible heat emitted by water heater and a generation model of latent heat due to steam from the water heater.

[0089] Here, a method for calculating the power consumption and heat load (amount of cooling and amount of heating) using the air conditioner model (air conditioner model of the air conditioner 11) will be described. The air conditioner model is given parameters such as a set temperature, a set air volume, a rated COP, and a rated power consumption for each operation mode of the air conditioner 11.

[0090] The air conditioner model is composed of the following equations (1) to (4). Q = F(ΔT1) (1) Q = ρ × Cp × Vol × ΔT2 (2) Load factor = Q ÷ rated capacity of outdoor unit (3) Power consumption = Q÷COP (4) In equations (1) to (4), Q is the amount of cooling when the air conditioner is cooling, and the amount of heating when the air conditioner is heating. In equation (1), F() is calculated by looking up Q in a table corresponding to ΔT1. The value of Q calculated using F() is a table showing the relationship between ΔT1 and Q, created based on the minimum, rated, and maximum capacities of the selected model. Specifically, the table is created with reference to the specifications, configuration, and control logic of the actual air conditioner. In equation (1), ΔT1 is the difference between the set temperature and the sensor value, and the sensor value is the intake temperature of the indoor unit. If the indoor unit can detect floor temperature, the difference between the set temperature and the floor temperature may be used instead of the intake temperature. In equation (2), ΔT2 is the difference between the supply air temperature and the sensor value. During heating, it is the supply air temperature minus the sensor value, and during cooling, it is the sensor value minus the supply air temperature. In equation (2), ρ is the density of air, Cp is the specific heat of air, and Vol is the supply air volume, which is a constant value.

[0091] The air conditioner model performs calculations (1) to (4), and returns to calculation (1) once calculation (4) is complete. First, Q is calculated using equation (1). In calculating Q using equation (1), ΔT1 is calculated based on information obtained from the air conditioner's operating data, and the capacity corresponding to ΔT1 is set as Q. Next, Q calculated using equation (1) is substituted into equation (2) to calculate the supply air temperature that constitutes ΔT2. Q calculated using equation (1) is substituted into the left side of equation (3) to calculate the load factor. Next, the COP corresponding to the load factor calculated using equation (3) is calculated from the relationship diagram between the load factor and COP. Then, Q calculated using equation (1) and the COP calculated are substituted into equation (4), and the left side of equation (4) is calculated as the power consumption corresponding to the current load factor. The characteristics of the relationship between load factor and COP are defined for each air conditioner model, and the relationship between load factor and COP is determined by specifying the rated COP and rated power consumption of the air conditioner in the air conditioner model. The relationship between load factor and COP can also be determined separately for cooling and heating. Other simulation conditions that are given to the air conditioner model include the operating mode (cooling, heating, dehumidification), set temperature, and set airflow.

[0092] Here, an example of creating a table showing the relationship between ΔT1 and Q will be described. The air conditioning load Q that the required air conditioner must process includes heat entering the room from the walls, floor, and ceiling (transmission heat), radiant heat (solar radiation, long-wave radiation), and internal heat generation (from people, lighting, and equipment). Radiant heat, including solar radiation, can be assumed to be absorbed by one of the solid surfaces in the room, so it can be included in the transmission heat. When measuring the floor temperature with the indoor unit 13, the infrared array sensor installed in the indoor unit 13 can measure not only the floor temperature but also the floor temperature, including internal heat generation (heat generation from people and equipment in the room), and these can be reflected in the control of the air conditioner.

[0093] To simplify table design, one method is to calculate the air conditioning load Q that an air conditioner must process using transverse heat. According to this method, the air conditioning load Q, which is transverse heat, can be calculated using the formula Q = α × A × ΔT1. Here, α is the indoor convection heat transfer coefficient, and is either a function of wind speed or a general fixed value for the indoor side. A is the total surface area of ​​the room (walls, floor, and ceiling). A is defined based on the standard room size assumed for the hardware capacity of the indoor unit 13 (air conditioner specifications). A is defined as an air conditioner model by creating a table showing the relationship between ΔT1 and Q from the transverse heat equation while changing the magnitude of ΔT1.

[0094] When evaporating temperature control is implemented using a simulator, the same implementation form as hardware can be considered. In general, it is difficult to implement a refrigeration cycle using an energy simulator. For this reason, it is possible to create a relationship diagram between the air conditioner's load factor and COP for each evaporating temperature offset value based on the performance characteristics of the hardware, and apply this to the air conditioner model of the energy simulator mentioned above. As mentioned above, the larger the evaporating temperature offset value, the more improved the COP characteristics. In addition, evaporation temperature control using an offset value is not limited to a method of manually setting the offset value, and the evaporation temperature offset value may be automatically changed according to the air conditioning load, as in a hardware implementation. Another possible method for implementing an evaporation temperature control simulator is a method similar to a hardware implementation, in which an energy simulator and a refrigeration cycle simulator are linked.

[0095] The communication unit 21 includes communication hardware such as a communication circuit conforming to a predetermined communication standard, and communicates with each device connected to the network NW.

[0096] The display 22 is configured with elements such as liquid crystal, LED (Light Emitting Diode), OLED (Organic LED), etc. The display 22 displays various information under the control of the control device 20.

[0097] The input unit 23 includes an interface circuit that connects to devices such as operation switches, a touch input panel, a mouse, and a keyboard, detects input operations by the operator P1, and outputs the detection results to the processor 200.

[0098] [1-4. Data used in the information output system] The data used in the information output system 1000 will be described. FIG. 4 is a diagram showing an example of the configuration of the basic data D1.

[0099] 4, the basic data D1 includes building data 42, area data 43, weather data 44, air conditioning device data 45, ventilation device data 46, plan data 47, and existing building data 48. These data are used when generating the simulation model 211.

[0100] The building data 42 includes information about the building BL, and this information is obtained, for example, from blueprints of the building BL. The building data 42 includes the location of the building BL, the number of floors FL, the number of areas AL, their orientation, and the uses of the areas AL. If the uses of the areas AL include stores, the building data 42 may also include the presence and placement of showcases in the areas AL used as stores. The building data 42 may also include the floor area and opening area of ​​the areas AL. The building data 42 includes first staffing ratio data and second staffing ratio data.

[0101] The building data 42 may include first staffing ratio data and second staffing ratio data. The first staffing ratio data and second staffing ratio data are reference values ​​common to multiple areas of building BL or values ​​corresponding to a specific area AL. The first staffing ratio data is information indicating changes in staffing ratios in area AL by time period. If building BL is a new construction, the first staffing ratio data is a value determined based on interviews with the client or construction company staff, actual values ​​in buildings similar to building BL, literature, etc. Information regarding the number and density of people prepared for ventilation design may be used as the first staffing ratio data. The second staffing ratio data may be information regarding changes in staffing ratios over time as specified in energy conservation standards, for example, information regarding staffing ratios for each room use as specified in WEBPRO. The first staffing ratio data is an example of "first staffing ratio information." The second staffing ratio data is an example of "second staffing ratio information."

[0102] The area data 43 includes information about the characteristics of each area. The area data 43 includes, for example, information about waterfronts that exist in the area. Waterfronts include the sea, rivers, lakes, marshes, etc., and the information about waterfronts is information about the location and area of ​​the waterfront. By comparing the location of the building BL with the area data 43, it is possible to determine whether there is a waterfront near the building BL, etc. Factors that cause an outdoor area to become highly humid include weather (high humidity, amount of rainfall, etc.), location (distance from mountains or water, wind direction, etc.), whether or not properties in the surrounding area have previously taken measures to combat humidity (ventilation and humidity control), and the opinions of the parties involved (building BL owners, users, contractors, clients, etc.) (high humidity, occurrence of condensation and black mold). Furthermore, for areas AL where humidity levels are likely to be high, the uses of area AL may be defined as follows: Example 1: Rooms and uses where people tend to gather in large numbers. Specifically, examples include relatively small conference rooms, rooms where long meetings or large meetings are held, school classrooms, hospital waiting rooms, elevator halls, etc. Example 2: Store kitchens and their surrounding areas. Example 3: Basements. By taking this information into consideration, it may be possible to determine whether area AL or the interior of area AL will become a high humidity area due to the use and usage of area AL.

[0103] The weather data 44 includes information about the weather in the area including the location of the building BL, and is, for example, data from the extended AMeDAS. The weather data 44 is used in the weather model.

[0104] The air conditioning device data 45 includes data related to the air conditioner 11. The air conditioning device data 45 is data associated with one type of air conditioner 11, and air conditioning device data 45 is prepared for each model number and type of air conditioner 11. The air conditioning device data 45 includes, for example, data related to the rated power consumption, cooling and heating capacities, and unit price of the air conditioner 11. The air conditioning device data 45 is used when generating an air conditioner model for the air conditioner 11.

[0105] The ventilation device data 46 includes data related to the ventilation device 15. The ventilation device data 46 is data associated with one type of ventilation device 15, and ventilation device data 46 is prepared for each model number and type of ventilation device 15. The ventilation device data 46 includes, for example, information on the type, function, ventilation volume, power consumption, and unit price of the ventilation device 15. The ventilation device data 46 is used when generating a ventilation equipment model of the ventilation device 15.

[0106] The planning data 47 includes information about the air conditioning equipment 1 to be installed in the building BL. Specifically, it includes information about the air conditioners 11 and ventilation devices 15 selected in steps (1) to (3) described above. The planning data 47 includes, for example, the model of the selected air conditioners 11, the number and placement of the indoor units 13 and outdoor units 12, and the type, number and placement of the ventilation devices 15. The planning data 47 is used in the air conditioner model, ventilation equipment model and building model of the building BL.

[0107] The existing building data 48 is data related to an existing building. The existing building data 48 may include data related to an existing building, such as the building data 42, weather data 44, air conditioning device data 45, and ventilation device data 46, or may include data added to these data. Examples of added data include the outdoor temperature, indoor temperature, power consumption, number of people, and human density measured in an existing building. If the building BL is an existing building and actual measured data exists for the building BL, that data is stored in the existing building data 48. The existing building data 48 may also be data related to a building different from the building BL. The existing building data 48 may include, for example, data related to an existing building located near the building BL or an existing building with similar conditions to the building BL. In this case, when the information output system 1000 executes an information provision service for the building BL, which is a newly constructed building, the existing building data 48 related to the other building can be reused.

[0108] [1-5. Operation] [1-5-1.Operation of terminal device] Fig. 5 is a flowchart showing the operation of the terminal device 2. Fig. 6 is an example of information output by the terminal device 2. The operation of the terminal device 2 in the first embodiment will be described with reference to these figures.

[0109] The operation of the terminal device 2 shown in Fig. 5 is executed by the processor 200. In Fig. 5, step S11 is executed by the acquisition unit 201, and steps S12-S16 are executed by the determination unit 202. Steps S17-S20 are executed by the information generation unit 204, and step S21 is executed by the output unit 205. In addition, in steps S17-S20, the information generation unit 204 uses the simulator 210 to cause the simulation model 211 to perform a simulation.

[0110] The terminal device 2 acquires the basic data D1 (step S11), and determines whether the location of the building BL is a high humidity area based on the acquired basic data D1 (step S12).

[0111] Whether the location of the building BL is in a high humidity area can be determined, for example, based on the building data 42 and the weather data 44. Specifically, the terminal device 2 identifies the location of the building BL based on the building data 42, and determines whether the location of the identified building BL belongs to a high humidity area based on the weather data 44.

[0112] A high humidity region is, for example, a region where the annual precipitation exceeds a threshold. It may also be, for example, a region where the number of days per year on which the average daily humidity exceeds the threshold is a predetermined number or more, or a region where there are months in which the average monthly humidity exceeds the threshold. The threshold and the predetermined number of days used for this determination are predetermined and included in the weather data 44 or the program 221.

[0113] The terminal device 2 may determine whether the location of the building BL is in a high humidity area based on whether there is a waterfront near the location of the building BL. The vicinity of the building BL refers to, for example, within a predetermined distance from the building BL. This determination can be made based on the location value of the building BL included in the building data 42 and the area data 43.

[0114] If it is determined that the location value of the building BL is in a high humidity area (step S12: YES), the terminal device 2 proceeds to step S17, which will be described later. If it is determined that the location value of the building BL is not a high humidity area (step S12: NO), the terminal device 2 determines whether the building BL has an area used as a store (step S13). If there is no area AL used as a store (step S13: NO), the terminal device 2 proceeds to step S15, which will be described later.

[0115] If there is an area AL that is used as a store (step S13: YES), the terminal device 2 determines whether a showcase is installed in the store (step S14). A showcase is, for example, a case with a door or a flat showcase that stores products such as food, and includes a device with a refrigeration function that cools the inside of the case.

[0116] If a showcase is installed in the store (step S14: YES), the terminal device 2 proceeds to step S17. If the store does not have a showcase (step S14: NO), the terminal device 2 proceeds to step S15.

[0117] In step S15, the terminal device 2 refers to the plan data 47 and determines whether the air conditioning equipment 1 to be installed in the building BL includes a ventilation device 15 and whether this ventilation device 15 is a total heat exchange ventilation device (step S15). If this condition is not met (step S15: NO), the terminal device 2 proceeds to step S16.

[0118] Furthermore, if the air conditioning equipment 1 to be introduced into the building BL includes the ventilation device 15, which is a total heat exchange ventilation device (step S15: YES), the terminal device 2 proceeds to step S17.

[0119] In step S16, the terminal device 2 determines whether the change in staffing ratio by time of day is large in at least any area AL of the building BL (step S16). Specifically, the terminal device 2 refers to the basic data D1 and determines whether the change in staffing ratio by time of day is equal to or larger than a threshold. If the change in staffing ratio by time of day is smaller than the threshold, the terminal device 2 determines that the change in staffing ratio is not large (step S16: NO), and ends this process.

[0120] If the change in staff ratio by time period is equal to or greater than the threshold value, the terminal device 2 determines that the change in staff ratio is large (step S16: YES), and proceeds to step S17.

[0121] In step S17, the terminal device 2 decides to recommend adding or changing the equipment included in the air conditioning equipment 1 selected in steps (1) to (3) (step S17). The terminal device 2 selects the equipment to be recommended for addition or change (step S18). The equipment selected by the terminal device 2 is selected from, for example, a ventilation device, a total heat exchanger, a humidity control outdoor air conditioning unit, a humidity control total heat exchanger, a ventilation device with a CO2 sensor, a total heat exchanger with a CO2 sensor, a humidity sensor-linked ventilation device, and an air conditioner with an outside air processing function.

[0122] In step S18, for example, if the air conditioning equipment 1 to be installed in the building BL does not include equipment with a function to adjust humidity in the area AL, the terminal device 2 recommends adding equipment with a function to adjust humidity. Here, the equipment with a function to adjust humidity is specifically a ventilation device 15. In other words, if the air conditioning equipment 1 selected in steps (1) to (3) does not include a ventilation device 15 in some or all of the areas AL of the building BL, the terminal device 2 recommends adding a ventilation device 15. In this case, the terminal device 2 recommends adding a ventilation device 15 and selects a ventilation device as the ventilation device 15. The terminal device 2 may also select a total heat exchanger, a humidity control outdoor air conditioning unit, a humidity control total heat exchanger, a ventilation device with a CO2 sensor, a total heat exchanger with a CO2 sensor, a humidity sensor-linked ventilation device, an air conditioner with a function to process outdoor air, a circulator, etc.

[0123] Furthermore, if the building BL includes an area AL that is used as a store and a showcase is to be installed in this store, in step S18 the terminal device 2 selects equipment that dehumidifies and ventilates the area AL and the ceiling (attic) space in the area AL, and a circulator that circulates the air inside the store.

[0124] Showcases with refrigeration or freezing functions can create low-temperature and high-temperature areas around them, causing condensation. Specifically, this can lead to condensation on the housing and front glass of doored showcases, as well as on the ceiling and attic space of a store. That is, when the cold air from a flat showcase installed on a store's sales floor cools the surface of the ceiling above the flat showcase, if the temperature in the attic space is high, condensation occurs on the ceiling surface due to the temperature difference between the ceiling and the attic space. In addition, condensation can occur in the attic space due to the temperature difference between the ceiling surface and the attic space. Because condensation can lead to mold, it is desirable to install equipment to suppress condensation inside stores and in attic spaces.

[0125] When a showcase is installed in a store, the terminal device 2 selects a ventilation device to ventilate the ceiling space of area AL in step S18. Alternatively, the terminal device 2 selects a humidity control outdoor air conditioning unit that reduces the humidity in the ceiling space of area AL. Furthermore, the terminal device 2 may select equipment that reduces the humidity in area AL where the showcase is installed, such as a humidity control total heat exchanger, a ventilation device with a CO2 sensor, a total heat exchanger with a CO2 sensor, a ventilation device linked to a humidity sensor, or an air conditioner with an outside air processing function. In addition, a circulator that circulates indoor air may be installed in area AL to prevent the showcase on the ceiling from cooling the room.

[0126] Furthermore, if the air conditioning equipment 1 to be installed in building BL includes a total heat exchange ventilator, the terminal device 2 selects a humidity-control total heat exchange ventilator as the equipment to recommend in place of the total heat exchange ventilator in step S18. Compared to a total heat exchange ventilator, a humidity-control total heat exchange ventilator uses a desiccant rotor to dehumidify.

[0127] Furthermore, if the air conditioning equipment 1 to be installed in building BL includes a total heat exchanger ventilator, the terminal device 2 may select a humidity sensor-linked ventilator as the equipment to recommend in place of the total heat exchanger ventilator in step S18. This device ventilates by repeatedly operating and stopping depending on the humidity and discomfort index of area AL using the humidity sensor function. This makes it possible to adjust the humidity in area AL while reducing power consumption.

[0128] The terminal device 2 generates comparison data comparing the presence and absence of the equipment selected in step S18 (step S19). In detail, the comparison data compares the air conditioning equipment 1 indicated by the plan data 47 with a configuration in which the equipment selected in step S18 is added to or replaced with the air conditioning equipment 1 indicated by the plan data 47. Items to be compared include initial cost, running cost, and indoor environment. The indoor environment is an evaluation of comfort in area AL, such as a comprehensive evaluation of temperature, humidity, discomfort index, and PMV.

[0129] The comparison data is generated using the information generation unit 204 and the simulator 210. As in the above-described process, the initial cost is calculated as the sum of the price obtained by multiplying the unit price of the air conditioners 11 by the number of units and the price obtained by multiplying the unit price of the ventilators 15 by the number of units. The terminal device 2 calculates the initial costs for both the case where the equipment selected in step S18 is present and the case where it is not present.

[0130] The running cost is calculated from the power consumption of the air conditioning equipment 1. The simulation model 211 calculates the power consumption of the air conditioning equipment 1 using an air conditioner model and a ventilation equipment model. The air conditioner model and the ventilation equipment model are provided with evaluation conditions, such as the operation mode (cooling / heating) of the air conditioner 11, the operation mode of the ventilation equipment 15, the operation period, the operation time zone, the set temperature, the set humidity, the type of air conditioner 11, and the type of ventilation equipment 15. In addition, the presence or absence of evaporation temperature control in the air conditioner 11 may be input as an evaluation condition. The power consumption of the air conditioning equipment 1 is calculated based on these evaluation conditions, the configurations of the air conditioner 11 and the ventilation equipment 15 indicated by the plan data 47, and the configuration of the ventilation equipment 15 selected by the terminal device 2 in step S18. The terminal device 2 regards the calculated power consumption or a value obtained by converting the power consumption into an electricity fee as evaluation data for the running cost. The simulator 210 may use a building model, a weather model, a solar radiation model, and an operational model (human body heat generation model, lighting equipment heat generation model, office equipment heat generation model, kitchen equipment heat generation model) to provide the air conditioner model and ventilation equipment model with conditions for outside temperature and heat generation in area AL.

[0131] When evaporating temperature control is implemented using an energy simulator, a relationship diagram between the load factor and COP of the air conditioner for each evaporating temperature offset value is created based on the operating performance characteristics of the actual air conditioner 11, and this is applied to the air conditioner model described above. The larger the evaporating temperature offset value, the better the COP characteristics. This method allows application based on multiple offset values. The offset value can be set not only manually, but also automatically by changing the evaporation temperature offset value. To automatically control the evaporation temperature, the evaporation temperature control offset value may be changed according to the air conditioning load. In the above method, the air conditioning load is estimated from the difference between the set temperature and the intake temperature in the air conditioner model. The evaporation temperature may also be controlled using information on humidity and discomfort index, just like in an actual unit.

[0132] Aside from simulation, the aforementioned air enthalpy method can be used to calculate energy-saving effects and running costs. Specifically, as mentioned above, in the case of a total heat exchanger, the air enthalpy method can be used to calculate the reduction in air conditioning load with or without a total heat exchanger based on the indoor and outdoor temperature and humidity conditions. The reduction in air conditioning load can then be used to calculate the electricity savings and horsepower savings of the air conditioner 11 achieved by installing a total heat exchanger. Furthermore, in the case of a humidity-control total heat exchanger, the reduction in air conditioning load is calculated using the same method as for a total heat exchanger, assuming the indoor humidity in area AL is controlled. For example, calculations are performed assuming the humidity is always controlled to 50% humidity and 20°C. Furthermore, in the case of a total heat exchanger equipped with a CO2 sensor, the reduction in airflow due to the CO2 sensor can be calculated using the same method as for a total heat exchanger, with the ventilation volume calculated based on the reduction in airflow due to the CO2 sensor.

[0133] The indoor environment is evaluated using the indoor temperature and humidity of area AL obtained by the simulation model 211, and the discomfort index of area AL calculated from these. The indoor temperature and humidity of area AL are calculated using a building model, a weather model, a solar radiation model, and an operation model (human body heat generation model, lighting equipment heat generation model, office equipment heat generation model, kitchen equipment heat generation model). An air conditioner model including a ventilation equipment model may also be used.

[0134] In the process of generating the comparison data in step S19, the terminal device 2 may use the existing building data 48. In this case, the terminal device 2 determines whether or not the existing building data 48 includes data on an existing building similar to building BL. Then, if there is a case where the device selected in step S18 has been installed in an existing building similar to building BL, the comparison data may be generated using the power consumption, indoor temperature, indoor humidity, etc. measured in this existing building.

[0135] An existing building similar to Building BL refers to an existing building in the same humidity environment as Building BL. Specifically, it refers to a building that has similar or common weather conditions and / or location conditions to Building BL. More specifically, it is a building that meets the following conditions: the building's location is close to Building BL, the distance from the building's location to the waterfront is about the same as Building BL, the weather at the location is similar to Building BL, etc.

[0136] The terminal device 2 generates assistance data 223 including the comparison data generated in step S19 (step S20), and outputs the assistance data 223 (step S21).

[0137] In step S20, the terminal device 2 performs a process of including in the assistance data 223 a message recommending the introduction of the device selected in step S18. Furthermore, in step S20, the terminal device 2 may include a message indicating that the required capacity value of the air conditioner 11 can be reduced by introducing the equipment selected in step S18.

[0138] As described above, a decrease in humidity in area AL reduces the load on the air conditioner 11, making it possible to adequately air-condition area AL with an air conditioner 11 with a lower capacity. In other words, the capacity value required of the air conditioner 11 in terms of design, i.e., the required value, can be changed to a lower value. This means that it is possible to adopt an air conditioner 11 with a lower unit price than the air conditioner 11 included in the planning data 47, which indicates the possibility of reducing the initial cost of the air conditioning equipment 1.

[0139] When including such a message in the assistance data 223, the terminal device 2 may add to the message a numerical value relating to the specific capacity of the air conditioner 11. For example, the terminal device 2 may add a general numerical value, prepared in advance, relating to the reduction in the load on the air conditioner 11 resulting from the introduction of the equipment selected in step S18. The terminal device 2 may also display the results of calculating and comparing the heat load of the air conditioner 11 when the equipment selected in step S18 is introduced and when it is not. The terminal device 2 may also include in the assistance data 223 the results of a simulation of the temperature, humidity, and possibility of condensation on the interior walls of the indoor back space and the indoor space. In addition, as described above, information indicating the advantages and disadvantages of different types of ventilation devices 15 may be included in the assistance data 223. For example, as described below, this information may be displayed on the information display screen 31. In this case, it is possible to encourage viewers of the information display screen 31 to understand the differences between models and types of ventilation devices 15.

[0140] Furthermore, when recommending the introduction of ventilation device 15 equipped with a CO2 sensor, terminal device 2 may calculate a first predicted amount of power consumption, which is the predicted power consumption when a first ventilation device having a CO2 sensor is introduced as ventilation device 15, and calculate a second predicted amount of power consumption, which is the predicted power consumption when a second ventilation device that is a ventilation device not equipped with a CO2 sensor is introduced, and generate assistance data 223 including a result of comparing these first predicted amount of power consumption and the second predicted amount of power consumption. Furthermore, terminal device 2 may generate assistance data 223 including a result of comparing a combination of a first initial cost, which is the initial cost when the first ventilation device is introduced, and the first predicted amount of power consumption, with a combination of a second initial cost, which is the initial cost when the second ventilation device is introduced, and the second predicted amount of power consumption.

[0141] The determination in step S12 may be performed by the determination unit 202 simply by referring to the basic data D1, or may utilize data input by an operator in the terminal device 2. For example, the terminal device 2 may request the terminal device 2 to input whether or not the location of the building BL falls within a high humidity area, and the terminal device 2 may acquire the data that the operator inputs into the terminal device 2 in response to this request. In this case, the terminal device 2 may determine whether or not the location falls within a high humidity area based on the data input by the operator, and analysis of the data acquired by the acquisition unit 201 may be omitted.

[0142] In the above process, step S11 is an example of an "acquisition step", steps S12, S13, S14, S15, and S16 are each an example of a "determination step", and step S21 is an example of an "output step".

[0143] [1-5-2. Output mode] FIG. 6 is a diagram showing an example of information output in the first embodiment, showing the assistance data 223 output by the terminal device 2 displayed on the terminal device 2. In FIG.

[0144] 6 is a screen displayed on the display of the terminal device 2 based on the assistance data 223. The information display screen 31 includes an evaluation condition display 32, a comparison data display 33, and a recommendation message .

[0145] The comparison data display 33 is a chart showing the results of evaluating the initial cost, running cost, and indoor environment of area AL for multiple configurations that could be candidates for the air conditioning equipment 1. The evaluation of the initial cost, running cost, and indoor environment is the content of the comparison data calculated in step S19. FIG. 6 shows an example of displaying three combinations of air conditioners 11 and ventilators 15. The comparison data display 33 shows the results of evaluating the initial cost, running cost, and indoor environment of area AL for the three combinations, Plan 1 to Plan 3.

[0146] Plan 1 shown in comparison data display 33 is a combination of the air conditioner 11 and ventilation device 15 selected in steps (1) to (3) above, and does not necessarily include the ventilation device 15. Plan 2 and Plan 3, the other two combinations shown in comparison data display 33, include the equipment selected in step S18. In other words, comparison data display 33 in Figure 6 is an example of a case where two sets of recommended equipment have been selected in steps S18-S20.

[0147] The evaluation condition display 32 displays the evaluation conditions used to calculate the initial cost, running cost, and indoor environment shown in the comparison data display 33.

[0148] Recommendation message 34 is a message recommending the introduction of the equipment selected in step S18. In the example of Fig. 6, a message explaining that it is recommended to ventilate the attic is displayed in recommendation message 34. This is just one example, and it may be a message explaining that plans 2 and 3 are superior to plan 1, or a message indicating that either plan 2 or plan 3 is recommended.

[0149] The recommendation message 34 may display the recommended type or model of the ventilation device 15 in addition to a message recommending the installation of the ventilation device 15. Furthermore, along with the model and type of the ventilation device 15, at least one of the advantages and disadvantages of installing each model or type of ventilation device 15 may be displayed. In this case, it becomes possible to consider installing the ventilation device 15 by taking into account the advantages and disadvantages of each model or type in addition to the initial cost, running cost, and indoor environment.

[0150] The terminal device 2 recommends adding or replacing humidity control equipment in area AL in a plan to install an air conditioning system 1 in building BL by outputting the support data 223 on the information display screen 31 or the like. This makes it possible to make useful suggestions about the air conditioning system 1 to be installed in building BL, and ultimately to support the formulation of an installation plan for the air conditioning system 1. When the support data 223 presented by the terminal device 2 includes comparison results including the location conditions of building BL and data from other buildings, it makes it possible to design the air conditioning system 1 taking into account the realistic conditions of building BL, assuming the actual operation of the air conditioning system 1.

[0151] The information display screen 31 in FIG. 6 is an example. For example, the information display screen 31 may include a comparison data display 33 that compares the case where an air conditioning system 1 that does not include a ventilation device 15 is installed with the case where an air conditioning system 1 that includes a ventilation device 15 is installed. The comparison data display 33 may also display values ​​of initial cost and running cost. When displaying the support data 223 that includes multiple simulation results, the comparison data display 33 may display each simulation condition in association with the simulation result. The recommendation message 34 may also include a chart or illustration such as a graph.

[0152] [1-6. Effects, etc.] As described above, the support method executed by the information output system 1000 of the first embodiment is a support method for supporting the formulation of a plan to introduce air conditioning equipment 1 including an air conditioner 11 into a building BL. This support method includes an acquisition step in which a computer acquires information related to humidity factors that affect the humidity in an area AL of the building BL. The support method also includes steps S12 to S16 as a determination step in which it is determined whether the humidity in area AL is likely to become high based on the information related to the humidity factors. The support method also includes step S21 as an output step in which, if it is determined that the humidity in area AL is likely to become high, it outputs support data 223 that recommends introducing a ventilation device 15 with a humidity control function.

[0153] According to this, when formulating a plan to introduce air conditioning equipment 1 into building BL, information on equipment with humidity control functions is output in response to humidity factors in area AL. Therefore, the formulation of a plan to introduce air conditioning equipment 1 into building BL can be supported by providing information that takes into account the humidity in area AL.

[0154] In the output step, the above support method outputs support data 223 that compares the capacity values ​​of the air conditioner 11 required for air conditioning in area AL when a ventilation device 15 with humidity control function is installed and when it is not installed.

[0155] This clearly shows the effect of reducing the load on the air conditioner 11 by introducing the ventilation device 15 with humidity control function. Therefore, it can more effectively support the formulation of a plan to introduce the air conditioning equipment 1 into the building BL.

[0156] In the output step, the support method outputs support data 223 that compares the amount of power consumed by the air conditioner 11 when the ventilation device 15 with humidity control function is installed and when it is not installed. This clearly shows the effect of reducing the running costs of the air conditioner 11 by introducing the ventilation device 15 with humidity control function. Therefore, it is possible to more effectively support the formulation of a plan to introduce the air conditioning equipment 1 into the building BL.

[0157] The support method outputs support data 223 including a simulated evaluation of the case where a ventilation device 15 with a humidity control function is introduced and the case where a ventilation device 15 with a humidity control function is not introduced. The evaluation by simulation is an evaluation of at least one of the temperature and humidity of area AL, the introduction cost of an air conditioner 11 required for air conditioning of area AL, and the amount of power consumption of the air conditioner 11.

[0158] This makes it possible to clearly show the effect of introducing the ventilation device 15 with humidity control function as an evaluation by simulation. Therefore, it is possible to more effectively support the formulation of a plan to introduce the air conditioning equipment 1 into the building BL.

[0159] The support method includes evaluation by simulation using data on temperature obtained from a building different from the building BL, and outputs support data 223 that recommends the introduction of a ventilation device 15 with a humidity control function.

[0160] This makes it possible to clearly show the effects of introducing the ventilation system 15 with humidity control function based on information proven in other buildings. Therefore, it is possible to more effectively support the formulation of a plan to introduce the air conditioning system 1 into the building BL.

[0161] The above support method includes the results of simulating the temperature, humidity, and possibility of condensation on the interior walls in the indoor back space of area AL and area AL, and outputs support data 223 recommending the introduction of a ventilation device 15 with humidity control function.

[0162] This makes it possible to more clearly show the effects of introducing the ventilation device 15 with humidity control function to the attic space and area AL, thereby more effectively supporting the formulation of a plan to introduce the air conditioning system 1 into building BL.

[0163] In the above support method, in the acquisition step, weather data 44 including information on the humidity in the area where building BL is located is acquired as information on humidity factors, and in the determination step, if the area where building BL is located is a high humidity area, it is determined that the humidity in area AL is likely to be high.

[0164] This makes it possible to more accurately determine targets for which the introduction of the ventilation device 15 with humidity control function should be recommended. Therefore, it is possible to more appropriately support the formulation of a plan to introduce the air conditioning equipment 1 into the building BL.

[0165] In the above support method, meteorological data 44, which is climate information for the location area of ​​the building BL, is acquired as information about humidity in the location area.

[0166] This makes it possible to more accurately determine targets for which the introduction of ventilation equipment 15 with humidity control function should be recommended using climate information. Therefore, it is possible to more appropriately support the formulation of a plan to introduce air conditioning equipment 1 into building BL.

[0167] The support method acquires area data 43 containing information indicating whether or not there is an area around the building BL that is prone to high humidity, as information regarding humidity in the location area.

[0168] This allows for more accurate determination of targets for which the introduction of ventilation devices 15 with humidity control functions should be recommended, taking into account the surrounding environment of the building BL. Therefore, more appropriate support can be provided for formulating a plan to introduce air conditioning equipment 1 into the building BL.

[0169] In the above support method, an acquisition step acquires existing building information, which is information about a building different from building BL and is about a building that has already installed a ventilation device 15 with humidity control function. Then, if the area where building BL is located is a high humidity area and the information about building BL is similar to the existing building information, an output step outputs support data 223, which includes information that a ventilation device 15 with humidity control function has been installed in another building in the past.

[0170] This makes it possible to more accurately determine targets for which the introduction of ventilation equipment 15 with humidity control function should be recommended based on information about existing buildings. Therefore, it is possible to more appropriately support the formulation of a plan to introduce air conditioning equipment 1 into building BL.

[0171] In the above support method, if it is determined in the judgment step that the humidity in area AL is likely to become high, support data 223 is output in the output step, which recommends the introduction of a ventilation device that works in conjunction with a humidity sensor as a device with humidity control function.

[0172] This will recommend the introduction of a ventilation device 15 with a humidity control function suitable for the building BL, thereby more appropriately supporting the formulation of a plan to introduce the air conditioning equipment 1 into the building BL.

[0173] In the above support method, when the area where building BL is located is a high humidity area and a total heat exchange ventilator is planned to be installed in building BL as the ventilation system 15 with humidity control function, the output step outputs predetermined support data 223. This predetermined support data 223 recommends installing a humidity-control total heat exchange ventilator with humidity control function using a desiccant rotor instead of the total heat exchange ventilator.

[0174] This will recommend the introduction of a ventilation device 15 with a humidity control function suitable for the building BL, thereby more appropriately supporting the formulation of a plan to introduce the air conditioning equipment 1 into the building BL.

[0175] In the above support method, when the area AL is a space used as a sales floor of a store and a showcase is installed in the sales floor, support data 223 is output in the output step, which includes a recommendation to install a ventilation device 15 with humidity control function in the sales floor. This will recommend the introduction of a ventilation device 15 with a humidity control function suitable for a store with a showcase, thereby more appropriately supporting the formulation of a plan to introduce an air conditioning system 1 into the building BL.

[0176] In the support method, an acquisition step acquires first occupancy ratio information indicating changes in occupancy ratio by time period in area AL. Then, a determination step determines whether area AL is a space where changes in occupancy ratio are large. If it is determined that changes in occupancy ratio in area AL are large, an output step outputs support data 223 including a recommendation to introduce a ventilation device 15 with humidity control function that controls the ventilation volume in area AL depending on the status of occupants in area AL.

[0177] This allows the introduction of a ventilation device 15 with humidity control function to be recommended in accordance with the staffing ratio in the building BL, thereby more appropriately supporting the formulation of a plan to introduce the air conditioning equipment 1 into the building BL.

[0178] In the above support method, when it is determined that there is a large change in the personnel ratio in area AL, in the output step, support data 223 is output that includes a recommendation to introduce a ventilation device equipped with a CO2 sensor as a ventilation device 15 with humidity control function.

[0179] This allows for the recommendation of the installation of equipment that can achieve both energy conservation and humidity control in accordance with the personnel ratio in building BL, thereby providing more appropriate support for the formulation of a plan to install air conditioning equipment 1 in building BL.

[0180] In the support method, in the acquisition step, second personnel ratio information, which is information regarding time changes in personnel ratio stipulated in the energy conservation standards, is acquired, and in the determination step, the first personnel ratio information is compared with the second personnel ratio information to determine whether the change in personnel ratio in area AL is large.

[0181] This allows for a more appropriate determination of the staffing ratio in the building BL and recommends the introduction of the ventilation device 15 with a humidity control function. Therefore, it is possible to more appropriately support the formulation of a plan to introduce the air conditioning equipment 1 into the building BL.

[0182] The support method calculates a first predicted power consumption, which is the predicted power consumption when a first ventilation device that is a ventilation device equipped with a CO2 sensor is installed. Also, the method calculates a second predicted power consumption, which is the predicted power consumption when a second ventilation device that is a ventilation device that is not equipped with a CO2 sensor is installed. The terminal device 2 outputs support data 223 including a result of comparing the first predicted power consumption and the second predicted power consumption.

[0183] This allows for more appropriate support in formulating a plan to introduce air conditioning equipment 1 into building BL by outputting information that allows for a comparison of power consumption when a ventilation device equipped with a CO2 sensor is introduced and when it is not.

[0184] The above support method outputs support data 223 including the results of comparing a combination of a first initial cost, which is the initial cost when a first ventilation device is introduced, and a first predicted power consumption amount, with a combination of a second initial cost, which is the initial cost when a second ventilation device is introduced, and a second predicted power consumption amount.

[0185] This allows for more appropriate support in formulating a plan to introduce air conditioning equipment 1 into building BL by outputting information that allows for a comparison of the initial costs of introducing a ventilation system equipped with a CO2 sensor with that of not.

[0186] The information output system 1000 is a support system that supports the formulation of a plan to introduce air conditioning equipment 1 including an air conditioner 11 into a building BL. The information output system 1000 includes an acquisition unit that acquires information about humidity factors that affect the humidity in an area AL of the building BL. The information output system 1000 also includes a determination unit that determines whether the humidity in the area AL is likely to become high based on the information about the humidity factors. The information output system 1000 also includes an output unit that outputs support data 223 that recommends introducing a ventilation device 15 with a humidity control function when it is determined that the humidity in the area AL is likely to become high. This provides the same effects as the above-described support method.

[0187] The program 221 is a computer-executable program that supports the formulation of a plan to introduce air conditioning equipment 1 including an air conditioner 11 into a building BL. The program 221 causes the computer to execute an acquisition step of acquiring information related to humidity factors that affect the humidity in an area AL of the building BL. The program 221 also causes the computer to execute a determination step of determining whether the humidity in the area AL is likely to become high based on the information related to the humidity factors. The program 221 also causes the computer to execute an output step of outputting assistance data 223 that recommends introducing a ventilation device 15 with a humidity control function when it is determined that the humidity in the area AL is likely to become high. This provides the same effects as the above-described support method.

[0188] (Embodiment 2) [2-1. Operation of terminal device] Fig. 7 is a flowchart showing the operation of the terminal device 2 in the second embodiment. Since the configuration of the information output system 1000 in the second embodiment is the same as that in the first embodiment, the same reference numerals are used for the components of the information output system 1000, and illustration and description thereof will be omitted. Fig. 7 shows another example of the operation described in the first embodiment with reference to Fig. 5. In Fig. 7, steps S11 to S21 are the same as those in Fig. 5.

[0189] In the second embodiment, after generating the comparison data in step S19, the terminal device 2 executes a process of estimating the influence of evaporation temperature control (step S31).

[0190] As described above, the hardware implementation will be described in two cases: automatic evaporation temperature control in accordance with the air conditioning load, and manual evaporation temperature control. When automatically controlling the evaporation temperature according to the air conditioning load, the air conditioner 11 estimates the air conditioning load from the difference between the indoor temperature and the set temperature of the indoor unit's area AL, and calculates the target values ​​for the indoor unit's 13 fan airflow and the indoor unit's 13 heat exchanger temperature. The outdoor unit 12 sets the lowest evaporation temperature target value among the target values ​​for each indoor unit 13. The air conditioning load can be calculated not only by temperature-based sensible heat load, but also by humidity-based latent heat load. A ventilation system with humidity control function determines the target humidity for area AL, and the magnitude of the latent heat load is defined based on the difference between the target humidity and the indoor humidity of area AL. The indoor temperature can be determined using the detected value of one of the following sensors: the intake temperature sensor of the indoor unit 13, the floor temperature sensor of the indoor unit 13, or the temperature sensor on the remote control. The humidity can be determined using the detected value of one of the following sensors: the humidity sensor of the indoor unit 13 or the humidity sensor on the remote control. The evaporation temperature control in the air conditioner 11 may be performed based on a discomfort index that is an index of both temperature and humidity.

[0191] In an embodiment in which the evaporation temperature control setpoint is manually set, each indoor unit 13 adjusts the expansion valve opening degree at each indoor unit 13 to maintain the indoor temperature at the set temperature. The outdoor unit 12 calculates the target value of the compressor rotation speed to maintain a constant evaporation temperature. In the manual mode, the evaporation temperature of the outdoor unit 12 is not controlled according to the air conditioning load of the indoor unit 13. Therefore, when the air conditioning load is low and the indoor humidity is low, the outdoor unit 12 starts and stops frequently, resulting in a decrease in COP. Here, the outdoor unit 12 can manually set an offset value to change the evaporation temperature when a low air conditioning load is expected. When evaporative temperature control is performed, the outdoor unit 12 applies the offset value to the set evaporation temperature. The offset value can be set in multiple stages, and the outdoor unit 12 calculates the target value of the compressor rotation speed based on the offset evaporation temperature and controls the compressor. The higher the evaporation temperature offset value, the greater the improvement in COP characteristics. Examples of evaporation temperature offset values ​​are as follows: Level (no correction): Offset value example 0℃ Evaporation temperature (upper limit) control value ±0℃ Level (Lv1): Offset value example +2°C Evaporation temperature (upper limit) control value +2°C Level (Lv2): Offset value example +4°C Evaporation temperature (upper limit) control value +4°C Level (Lv3): Offset value example +6°C Evaporation temperature (upper limit) control value +6°C

[0192] When evaporating temperature control is implemented using a simulator, the same implementation form as hardware can be considered. In general, it is difficult to implement a refrigeration cycle using an energy simulator. For this reason, it is possible to create a relationship diagram between the air conditioner's load factor and COP for each evaporating temperature offset value based on the performance characteristics of the hardware, and apply this to the air conditioner model of the energy simulator mentioned above. As mentioned above, the larger the evaporating temperature offset value, the more improved the COP characteristics. In addition, evaporation temperature control using an offset value is not limited to a method of manually setting the offset value, and the evaporation temperature offset value may be automatically changed according to the air conditioning load, as in a hardware implementation. Another possible method for implementing an evaporation temperature control simulator is a method similar to a hardware implementation, in which an energy simulator and a refrigeration cycle simulator are linked.

[0193] However, when evaporative temperature control is performed, the compressor rotation speed of the outdoor unit 12 is suppressed, reducing the air conditioning load processing capacity. For this reason, it may be appropriate not to perform evaporative temperature control when area AL is in a high humidity state. Specific examples of situations in which automatic evaporative temperature control is inappropriate include sudden changes in weather conditions, such as during the change of seasons or during a heatwave, and sudden changes in air conditioning load due to an increase or decrease in the number of people in a room, such as a waiting room or elevator hall, making it difficult for the evaporative temperature control to keep up with the changes in air conditioning load, making it impossible to set an appropriate evaporative temperature value. Examples of situations in which manual setting of the evaporative temperature is inappropriate include the above cases, as well as when it is impossible to set an appropriate offset value that can handle the air conditioning load.

[0194] In the operation shown in FIG. 7, the impact of evaporation temperature control is estimated when the location value of building BL is a high humidity area (step S12), when there is a store with a showcase in building BL (step S14), and when there is a large change in occupancy ratio (step S16). In all of these cases, area AL is prone to high humidity. If there are conditions that make area AL prone to high humidity, the terminal device 2 estimates in step S31 that it is appropriate not to perform evaporation temperature control. In step S20, the terminal device 2 generates support data 223 including the estimation result of step S31.

[0195] In step S31, the terminal device 2 may identify an area AL where the effects of evaporation temperature control are likely to occur. For example, this may be the aforementioned high humidity area or the aforementioned area where a sudden change in air conditioning load occurs. In addition, the terminal device 2 identifies the outdoor units 12 connected to the indoor units 13 in the area AL where the ventilation device 15 is not installed, based on the building data 42 and the plan data 47. Then, the terminal device 2 generates an estimation result that it is appropriate not to perform evaporation temperature control for the identified outdoor units 12.

[0196] To estimate whether it is appropriate not to perform evaporation temperature control, the terminal device 2 may determine whether the humidity in the intermediate season in the area where the building BL is located is equal to or greater than a predetermined value. In this case, the terminal device 2 acquires the humidity in the intermediate season for the location of the building BL from the weather data 44. The intermediate season refers to a season other than summer and winter, and may also exclude the rainy season. Furthermore, the terminal device 2 may estimate that it is appropriate not to perform evaporation temperature control when the number of days with a high discomfort index continues for a predetermined number of days or more in the area where the building BL is located.

[0197] The terminal device 2 may also generate support data 223 that recommends limiting the setting of the evaporation temperature control in accordance with the occupancy ratio in the area AL. In an area AL with many people, sensible heat load and latent heat load occur depending on the number of people, and the latent heat load increases as the number of people increases. The terminal device 2 evaluates the thermal environment of the area AL when the offset value of the evaporation temperature control is changed using the operation model of the simulation model 211. In this process, the first occupancy ratio data and the second occupancy ratio data of the building data 42 can be used. Then, the terminal device 2 determines an appropriate offset value or an upper limit for the offset value in the evaporation temperature control, and recommends performing evaporation temperature control with an offset value equal to or less than this upper limit.

[0198] Outdoor factors that cause Area AL to become a high-humidity area include weather (high humidity, rainfall, etc.), location (distance from mountains or water, wind direction, etc.), whether or not properties in the surrounding area have previously undergone humidity control measures (ventilation, humidity control), and opinions of the parties involved (building BL owner, user, contractor, client, etc.) (high humidity, condensation, black mold occurrence). Area AL, where indoor humidity is likely to be high, may also be defined by its use as follows: Example 1: Rooms and uses where people tend to gather. Specifically, these include relatively small conference rooms, rooms where long meetings or large groups are held, school classrooms, hospital waiting rooms, elevator halls, etc. Example 2: Store kitchens and their surrounding areas Example 3: Basements By taking these information into account, it may be possible to determine whether Area AL or the interior of Area AL will become a high-humidity area due to the use and usage of Area AL.

[0199] In the second embodiment, for example, when it is appropriate not to perform evaporation temperature control, the terminal device 2 displays a screen including a message informing the user that it is appropriate not to perform evaporation temperature control, or outputs the data of this screen. This screen can be, for example, the same as the information display screen 31. Examples of messages displayed on the information display screen 31 include, for example, a message explaining that it is recommended not to use evaporation temperature control settings when building BL or area AL is used as an office because it has been determined to be a high humidity area, or a message recommending the use of evaporation temperature control in area AL during intermediate periods or when there are few people.

[0200] [2-2. Effects, etc.] As explained above, the support method executed by the information output system 1000 of embodiment 2 is a support method for supporting the formulation of a plan to introduce air conditioning equipment 1 including an air conditioner 11 into building BL. This support method includes an acquisition step of acquiring, by a computer, information regarding humidity factors that affect the humidity in area AL of building BL. It also includes a determination step of determining whether the humidity in area AL is likely to become high based on the information regarding the humidity factors. It also includes an output step of outputting support data 223, when it is determined that the humidity in area AL is likely to become high, that includes information indicating that comfort in area AL may be impaired by performing evaporation temperature control that increases the evaporation temperature during cooling operation in area AL.

[0201] According to this, when formulating a plan to introduce the air conditioning equipment 1 into the building BL, information related to the evaporation temperature control of the air conditioner 11 is output in response to the humidity factor of the area AL. Therefore, the formulation of a plan to introduce the air conditioning equipment 1 into the building BL can be supported by providing information that takes into account the humidity of the area AL.

[0202] In the above support method, when it is determined that the humidity in area AL is likely to become high, in the output step, support data 223 is output, which includes information that the comfort of area AL may be impaired by performing evaporation temperature control using an outdoor unit connected to an indoor unit installed in area AL in building BL where a ventilation device 15 with humidity control function is not installed.

[0203] This outputs information that specifically indicates the impact on the area AL of performing evaporation temperature control, thereby more effectively supporting the formulation of a plan to introduce the air conditioning equipment 1 into the building BL.

[0204] In the determination step, the support method determines that the humidity in the area AL is likely to become high if the humidity in the intermediate season in the area where the building BL is located is equal to or higher than a predetermined value.

[0205] This allows the impact of evaporative temperature control on area AL to be determined based on the climate of the area where building BL is located, thereby more appropriately supporting the formulation of a plan to introduce air conditioning equipment 1 into building BL.

[0206] In the above support method, if the area where building BL is located is a high humidity area, it is determined that the humidity in area AL is likely to become high in the determination step. Then, in the output step, support data 223 is output that recommends keeping the evaporation temperature setting value in evaporation temperature control low.

[0207] This allows the impact of evaporative temperature control on area AL to be determined based on the climate of the area where building BL is located, thereby more appropriately supporting the formulation of a plan to introduce air conditioning equipment 1 into building BL.

[0208] In the above support method, in an acquisition step, occupancy information for area AL of building BL is acquired as information related to humidity factors. Then, in an output step, support data 223 including information recommending that the recommended value of the evaporating temperature of the outdoor unit be increased is output, the lower the occupancy rate for area AL corresponding to the outdoor unit of the air conditioner 11.

[0209] This allows the system to determine the impact of evaporating temperature control on area AL based on the proportion of people in building BL, and output information corresponding to the number of people. This provides more appropriate support for formulating a plan to introduce air conditioning equipment 1 into building BL.

[0210] The information output system 1000 is a support system that supports the formulation of a plan to introduce air conditioning equipment 1 including an air conditioner 11 into a building BL. The information output system 1000 includes an acquisition unit that acquires information related to humidity factors that affect the humidity in an area AL of the building BL. The information output system 1000 also includes a determination unit that determines whether the humidity in the area AL is likely to become high based on the information related to the humidity factors. The information output system 1000 also includes an output unit that, when it is determined that the humidity in the area AL is likely to become high, outputs support data 223 that includes information indicating that comfort in the area AL may be impaired by performing evaporation temperature control that increases the evaporation temperature during cooling operation in the area AL. This provides the same effects as the above-described support method.

[0211] The program 221 is a program executable by a computer to assist in formulating a plan to introduce air conditioning equipment 1 including an air conditioner 11 into a building BL. The program 221 causes the computer to execute an acquisition step of acquiring information related to humidity factors that affect the humidity in an area AL of the building BL. The program 221 also causes the computer to execute a determination step of determining whether the humidity in the area AL is likely to become high based on the information related to the humidity factors. The program 221 also causes the computer to execute an output step of outputting assistance data 223 including information indicating that, if it is determined that the humidity in the area AL is likely to become high, comfort in the area AL may be impaired by performing evaporation temperature control that increases the evaporation temperature during cooling operation in the area AL. This provides the same effects as the above-described support method.
