[0002] Conventionally, an air conditioning equipment design support system that supports the design of a large number of air conditioning devices included in an air conditioning equipment is known (see, for example, Patent Document 1 below). The system described in Patent Document 1 has the following steps (A) to (E).

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-120982 Summary of the Invention [Problem to be solved by the invention]

[0006] Generally, when calculating air conditioning operating costs and installation costs, existing simulation software is used, such as the system described in Patent Document 1. However, existing simulation software requires the input of various information such as building information, area, and specifications, and this input work can take several hours to several days.

[0007] Furthermore, the information entered into existing simulation software must be updated whenever the building plan or specifications are changed. This requires time and effort, especially in the early design stages when the design may change significantly, and the associated costs make it difficult to implement existing software.

[0008] Furthermore, if the building is a logistics warehouse, the air conditioning operating costs and installation costs can change significantly depending on the number and layout of rooms such as handling rooms and storage rooms, and the type, number, and temperature settings of air conditioning equipment.

[0009] However, with existing simulation software, comparing air conditioning operating costs and installation costs when the conditions of a logistics warehouse are changed requires inputting various information each time the conditions are changed, which takes a lot of time and effort.In addition, each time the conditions are changed, the output results must be saved and the saved results must be compared separately.

[0021] Hereinafter, embodiments of the air conditioning cost calculation device, the air conditioning cost calculation method, and the program of the present invention will be described with reference to the accompanying drawings. Note that in this specification and the drawings, substantially identical components are designated by the same reference numerals, and redundant explanations may be omitted.

[0022] Figure 1 is a block diagram showing an embodiment of an air conditioning cost calculation device according to the present invention. The air conditioning cost calculation device 2 of this embodiment is configured by a user terminal 1, which is, for example, a personal computer (PC). The user terminal 1 is, for example, a desktop PC, a notebook PC, or a tablet PC. The user terminal 1 has the air conditioning cost calculation device 2, a communication IF 3, and an input / output IF 4.

[0023] The details will be described later, but the air conditioning cost calculation device 2 is a device that calculates the air conditioning costs of a logistics warehouse that has multiple rooms, including a material handling room and a storage room. The air conditioning costs of a logistics warehouse include air conditioning operating costs and air conditioning installation costs. The air conditioning operating costs are the running costs incurred by using air conditioning in the logistics warehouse, and the air conditioning installation costs are the initial costs incurred when installing air conditioning in the logistics warehouse.

[0024] The air conditioning cost calculation device 2 includes, for example, a CPU (Central Processing Unit) 21, an NVRAM (Non-Volatile RAM) 22, a RAM (Random Access Memory) 23, a ROM (Read Only Memory) 24, and an HDD (Hard Disc Drive) 25. These components that make up the air conditioning cost calculation device 2 are connected via a bus so that they can send and receive data.

[0025] The CPU 21 is a central processing unit that performs overall control of the air conditioning cost calculation device 2. The NVRAM 22 stores, for example, preset information set by the user and user setting information. The RAM 23 provides a working area for the CPU 21. The ROM 24 and HDD 25 store various programs and various data used by each program. The CPU 21 loads the programs stored in the ROM 24 or HDD 25 into the RAM 23 and executes them, thereby realizing various functions for calculating and displaying the total cost of air conditioning, including the air conditioning operating costs and air conditioning installation costs.

[0026] The communication IF3 is an interface for communicating with other user terminals, server devices, etc. via a network. Networks include public networks such as the Internet, wireless networks such as mobile phone networks, dedicated networks such as VPNs (Virtual Private Networks), LANs (Local Area Networks), etc.

[0027] For example, a person in charge of making a proposal to a customer regarding air conditioning for a logistics warehouse can transmit total cost data, including air conditioning operating costs and air conditioning installation costs, calculated by the air conditioning cost calculation device 2 to the customer's user terminal via the communication IF 3 and the network and display it. The person in charge can also upload the total cost data calculated by the air conditioning cost calculation device 2 to a server device on the network via the communication IF 3. In this case, the customer can access the server device using their own user terminal, download the total cost data from the server device, and display it on their own user terminal.

[0028] The input / output IF4 is an interface for inputting and outputting data to and from devices connected to the user terminal 1. Input devices such as a keyboard, a touch panel, a mouse or other pointing device, and a microphone are connected to the input / output IF4. The user terminal 1 obtains information relating to user operations and inputs to the input devices from the input devices via the input / output IF4.

[0029] Furthermore, a display device such as a liquid crystal panel (LCD: Liquid Crystal Display) or an organic EL panel (EL: Electroluminescence), and an output device such as a printer or speaker are connected to the input / output IF4. The air conditioning cost calculation device 2 can display the calculated total cost data of air conditioning on a display device via the input / output IF4, or output it from an output device.

[0030] Fig. 2 is a functional block diagram of the air conditioning cost calculation device 2 shown in Fig. 1. As shown in Fig. 2, the air conditioning cost calculation device 2 has a storage unit 201, a setting unit 202, a heat load calculation unit 203, an air conditioning operating cost calculation unit 204, an air conditioning installation cost calculation unit 205, and a display unit 206. Each unit of the air conditioning cost calculation device 2 shown in Fig. 2 represents a function of the air conditioning cost calculation device 2 that is realized when the CPU 21 shown in Fig. 1 loads a program stored in the ROM 24 or HDD 25 into the RAM 23 and executes it.

[0031] At least some of the components of the air conditioning cost calculation device 2 shown in Fig. 2 may be provided by a DSP (Digital Signal Processor), a GPU (Graphics Processing Unit), etc. At least some of the components of the air conditioning cost calculation device 2 shown in Fig. 2 may be a dedicated LSI (Large Scale Integration) such as an FPGA (Field-Programmable Gate Array), a numerical calculation processor, or an image processing processor, or other digital circuitry.

[0032] The operation of the air conditioning cost calculation device 2 of this embodiment, and an embodiment of the air conditioning cost calculation method and program according to the present invention will be described below with reference to Fig. 3. Fig. 3 is a flow diagram showing an embodiment of the air conditioning cost calculation method according to the present invention. The air conditioning cost calculation method of this embodiment is implemented by the air conditioning cost calculation device 2. Furthermore, the program of this embodiment causes the air conditioning cost calculation device 2 to implement the air conditioning cost calculation method of this embodiment.

[0033] When the air conditioning cost calculation device 2 starts the flow of the air conditioning cost calculation method shown in Fig. 3, it first executes a process to store preset information (step P1). The air conditioning cost calculation device 2 also executes a process to set user information (step P2). The order of steps P1 and P2 is not particularly limited, and either step may be executed first, or both steps may be executed simultaneously.

[0034] In step P1, the storage unit 201 stores preset information including the insulation performance, ventilation conditions, indoor heat generation amount for each room in the logistics warehouse, weather conditions, air conditioning equipment unit prices, air conditioning equipment efficiency, and electricity unit prices, as shown in Fig. 2. In step P2, the setting unit 202 sets user setting information including the area and layout of the rooms in the logistics warehouse, and the air conditioning method, air conditioning time, and set temperature for each room, as shown in Fig. 2. The storage unit 201 may store the area and layout of the rooms in the logistics warehouse as preset information.

[0035] Fig. 4 is an example of a setting screen for preset information and user setting information. In steps P1 and P2, the display unit 206 of the air conditioning cost calculation device 2 shown in Fig. 2 displays a setting screen SS1 for preset information and user setting information as shown in Fig. 4 on a display device connected to the input / output IF4 of the user terminal 1, for example. A user of the air conditioning cost calculation device 2 inputs the preset information and user setting information using an input device such as a keyboard, mouse, or touch panel connected to the input / output IF4 shown in Fig. 1.

[0036] In the example shown in Figure 4, the setting screen SS1 has input fields for the exterior specifications, floor height, and construction site, which are input items for setting the insulation performance and weather conditions for each room, which are preset information. When the construction site of the logistics warehouse is entered on the setting screen SS1, the storage unit 201 references data on weather conditions for each region and stores the weather conditions corresponding to the entered construction site as preset conditions. In addition, when the exterior specifications and floor height are entered on the setting screen SS1, the storage unit 201 references data on the exterior specifications and insulation performance, and stores the insulation performance corresponding to the entered exterior specifications and floor height as preset conditions.

[0037] Furthermore, for example, when a property name is input on setting screen SS1, setting unit 202 stores the property name as user setting information in storage unit 201. Furthermore, when the number of sections is input on setting screen SS1, setting unit 202 sets a room layout according to the number of sections as the room arrangement, and stores the room arrangement as user setting information in storage unit 201. Storage unit 201 and setting unit 202 also accept user inputs for other items of preset information and user setting information not shown in Fig. 4 via setting screens similar to those in Fig. 4, and store the preset information and set the user setting information.

[0038] Thereafter, the air conditioning cost calculation device 2 executes a process (step P3) for creating logistics design data, as shown in Fig. 3. In this step P3, the setting unit 202 creates one logistics warehouse design based on the user setting information set in the previous step P2, and sets this as logistics warehouse design data. Also, in this step P3, the display unit 206 may, for example, display the logistics warehouse design data created by the setting unit 202 on a display device connected to the input / output IF4 of the user terminal 1.

[0039] 5 shows an example of a logistics warehouse design WD displayed on a display device connected to the input / output IF4 of the user terminal 1. In the illustrated example, the setting unit 202 creates a 3 x 3 logistics warehouse design WD based on the room layout included in the user setting information set in the previous process P2. The logistics warehouse design WD includes, for example, the preset information and user setting information set in the previous processes P1 and P2.

[0040] Specifically, the warehouse design WD includes preset information such as the insulation performance, ventilation conditions, and indoor heat generation for each room in the warehouse. The warehouse design WD also includes user-defined information such as the area and layout of the room, the air conditioning method for each room, the air conditioning time, and the set temperature.

[0041] Furthermore, the setting unit 202 may accept settings and changes to user setting information in step P3. Specifically, in the example shown in Fig. 5, in a logistics warehouse design WD displayed in the form of a 3 x 3 room floor plan, the top three rooms are set as handling rooms DR, and the six rooms below them are set as storage rooms SR. In this case, the user may select each room via an input device such as a mouse or touch panel, and change the handling room DR to a storage room SR, or change the storage room SR to a handling room DR.

[0042] 6 and 7 are examples of the setting screen SS2 for user setting information. In the example shown in Fig. 6, the setting unit 202 accepts settings and changes to the air conditioning method for each room, which is user setting information, in step P3. Specifically, the user selects an icon indicating spot air conditioning using, for example, a mouse or touch panel connected to the input / output IF4 of the user terminal 1, and then selects the material handling room DR in the center of the top shelf of the logistics warehouse design WD. As a result, the air conditioning method for this material handling room DR is set to spot air conditioning.

[0043] Similarly, the user selects, for example, an icon indicating overall air conditioning, and then selects the storage rooms SR in the middle and bottom rows on the far left side of the logistics warehouse design WD. As a result, the air conditioning method for these storage rooms SR is set to overall air conditioning. Note that in the examples shown in Figures 6 and 7, the other white rooms that are neither spot air conditioning nor overall air conditioning do not have an air conditioning method set, i.e., they represent rooms in which no air conditioning equipment is installed.

[0044] 7 shows an example in which a setting screen SS3 for setting user-defined information such as the set temperature is displayed when the user selects the material handling room DR in the center of the top row of the logistics warehouse design WD, for which spot air conditioning has been set as the air conditioning method. In this way, in process P3, the user can select each room in the logistics warehouse design WD and set or change user-defined information including the type of room (material handling room DR, storage room SR, etc.), the air conditioning method for each room, the set temperature for heating and cooling, whether to open or close the shutters, whether to ventilate, and the amount of ventilation.

[0045] Next, the air conditioning cost calculation device 2 executes a process to calculate the heat load for each room in the logistics warehouse (step P4), as shown in Fig. 3. In this step P4, the heat load calculation unit 203 calculates the heat load for each room based on the set temperature for each room set by the setting unit 202, the logistics warehouse design data, the insulation performance, ventilation conditions, and indoor heat generation amount for each room included in the preset information, and weather conditions.

[0046] The heat load for each room in a logistics warehouse can be calculated based on, for example, the heat transmitted through the exterior walls of the warehouse Hg [W] and the heat generated by lighting equipment Hl [W]. Specifically, the heat transmitted through the exterior walls Hg [W] is calculated, for example, using the following formula (1), and the heat generated by lighting equipment Hl [W] is calculated, for example, using the following formula (2).

[0047] Hg = Ug × Sg × (to-ti) (1) Hl = Wl × Sf (2)

[0048] In the above formula (1), Ug is the heat transfer coefficient of the exterior wall [W / m 2 K], Sg is the area of ​​the exterior wall [m 2 ], to is the outdoor temperature [K], and ti is the indoor temperature [K]. In the above formula (2), Hl is the heat generation amount of the lighting fixture per unit floor area of ​​the room [W / m 2 ], Sf is the floor area of ​​the room. If the number of workers in each room is fixed, the heat generated by the workers in each room can be used to calculate the heat load of each room.

[0049] Next, the air conditioning cost calculation device 2 executes a process (step P5) to calculate the air conditioning operating cost for each room, as shown in Fig. 3. In this step P5, the air conditioning operating cost calculation unit 204 calculates the annual air conditioning operating cost for each room based on the heat load for each room calculated by the heat load calculation unit 203, the air conditioning method and air conditioning time for each room set by the setting unit 202, and the air conditioning equipment efficiency and electricity unit price included in the preset information. Here, the air conditioning equipment efficiency is the ratio of energy consumption to heating and cooling capacity, and is a value determined by the air conditioning equipment. The electricity unit price is determined, for example, depending on the construction site.

[0050] Next, the air conditioning cost calculation device 2 executes a process (step P6) to calculate the air conditioning installation cost for each room, as shown in Fig. 3. In this step P6, the air conditioning installation cost calculation unit 205 calculates the air conditioning installation cost for each room based on the air conditioning method set by the setting unit 202, the heat load for each room calculated by the heat load calculation unit 203, and the air conditioning equipment unit price included in the preset information.

[0051] Next, the air conditioning cost calculation device 2 executes a process (step P7) of displaying the total cost data, as shown in Fig. 3. In this step P7, the display unit 206 displays the total cost data, on which the air conditioning operating costs and the air conditioning installation costs are superimposed, for each room in the logistics warehouse design, on a display device connected to the input / output IF4 of the user terminal 1.

[0052] Fig. 8 shows an example of a display screen DS of total cost data displayed on a display device connected to the input / output IF4 of the user terminal 1. In the example shown in Fig. 8, the display unit 206 simultaneously displays three different pieces of total cost data, proposal 1 to proposal 3, on one display screen DS.

[0053] In Proposal 1, the air conditioning method for the three material handling rooms DR located on the upper level of the logistics warehouse design WD is set to spot air conditioning, while the air conditioning method for the six storage rooms SR located on the middle and lower levels is set to general air conditioning. In Proposal 2, the air conditioning method for the one material handling room DR located in the center of the upper level of the logistics warehouse design WD is set to spot air conditioning, while the air conditioning method for the two storage rooms SR located on the middle and lower levels on the far left is set to general air conditioning. In Proposal 3, the air conditioning method for the three material handling rooms DR located on the upper level of the logistics warehouse design WD is set to spot air conditioning.

[0054] In this case, the memory unit 201 stores multiple pieces of user setting information in which at least one of the air conditioning method, air conditioning time, and set temperature for each room is different and set by the setting unit 202. The display unit 206 also simultaneously displays multiple pieces of total cost data calculated by the heat load calculation unit 203, the air conditioning operation cost calculation unit 204, and the air conditioning installation cost calculation unit 205 based on each of the different user setting information. In the example shown in Fig. 8, it can be seen that the air conditioning method and set temperature of adjacent rooms affect the heat load of each room, so different air conditioning operation costs and air conditioning installation costs are calculated for each room even when the same air conditioning method is used.

[0055] The following describes the operations of the air conditioning cost calculation device 2, the air conditioning cost calculation method, and the program of this embodiment.

[0056] As described above, the air-conditioning cost calculation device 2 of this embodiment is a device that calculates the air-conditioning costs of a logistics warehouse having multiple rooms, including a material handling room DR and a storage room SR. The air-conditioning cost calculation device 2 includes a memory unit 201, a setting unit 202, a heat load calculation unit 203, an air-conditioning operation cost calculation unit 204, an air-conditioning installation cost calculation unit 205, and a display unit 206. The memory unit 201 stores preset information, including the insulation performance, ventilation conditions, indoor heat generation amount, weather conditions, air-conditioning equipment unit price, air-conditioning equipment efficiency, and electricity unit price, for each room in the logistics warehouse. The setting unit 202 creates a logistics warehouse design WD and generates logistics warehouse design data by setting user setting information, including the area and layout of the rooms, and the air-conditioning method, air-conditioning time, and set temperature for each room. The heat load calculation unit 203 calculates the heat load for each room based on the logistics warehouse design data generated by the setting unit 202, the insulation performance, ventilation conditions, and indoor heat generation amount for each room included in the preset information, as well as weather conditions, and the set temperature for each room set by the setting unit. The air conditioning operation cost calculation unit 204 calculates the air conditioning operation cost based on the heat load for each room calculated by the heat load calculation unit 203, the air conditioning method and air conditioning time for each room set by the setting unit 202, and the air conditioning equipment efficiency and electricity unit price included in the preset information. The air conditioning installation cost calculation unit 205 calculates the air conditioning installation cost based on the heat load for each room calculated by the heat load calculation unit 203 and the air conditioning equipment unit price included in the preset information. The display unit 206 then displays total cost data in which the air conditioning operation cost and air conditioning installation cost are superimposed for each room in the logistics warehouse design WD.

[0057] With this configuration, a user of the air-conditioning cost calculation device 2 of this embodiment can register preset information in advance in the storage unit 201, as shown in FIGS. 4 and 5, and then use the setting unit 202 to determine the area and layout of the rooms in the logistics warehouse. As a result, the user can simply change the air-conditioning method, air-conditioning time, and set temperature for each room in the logistics warehouse using the setting unit 202, as shown in FIGS. 6 and 7, and then compare various total cost data displayed on the display device using the display unit 206, as shown in FIG. 8. Furthermore, once the preset information is registered, the user can subsequently change the air-conditioning method, air-conditioning time, and set temperature for each room in the logistics warehouse using the setting unit 202 without having to input the preset information. Therefore, the air-conditioning cost calculation device 2 of this embodiment makes it easy to compare air-conditioning operating costs and air-conditioning installation costs when the conditions of the logistics warehouse are changed.

[0058] Furthermore, in the air conditioning cost calculation device 2 of this embodiment, the storage unit 201 stores a plurality of pieces of user setting information, each of which differs in at least one of the air conditioning method, air conditioning time, and set temperature for each room, set by the setting unit 202. Furthermore, the display unit 206 simultaneously displays a plurality of pieces of total cost data corresponding to each piece of user setting information stored by the storage unit 201, as shown in Fig. 8 .

[0059] With this configuration, the air conditioning expense calculation device 2 of this embodiment can display a list of multiple total cost data items on the display screen DS by the display unit 206 when the air conditioning method, air conditioning time, and set temperature are changed for each room in a logistics warehouse, as in Proposal 1 to Proposal 3 in Fig. 8.
