Embodiments for Carrying Out the Invention

[0009] Hereinafter, an information processing method, a program, and an information processing system according to an embodiment will be described with reference to the drawings. However, the following embodiment is merely one of various embodiments of the present disclosure. The following embodiment can be variously modified according to design and the like as long as the object of the present disclosure can be achieved.

[0010] (1) Overview The information processing method of the present embodiment is used for designing the air conditioning of a facility 5 (see FIG. 2). More specifically, the information processing method is used for selecting air conditioning equipment installed in the facility 5 and determining the arrangement of the air conditioning equipment. The air conditioning equipment is equipment that adjusts the indoor temperature by heat exchange. Examples of the air conditioning equipment include air conditioners and heat pipes.

[0011] As shown in FIG. 1, the information processing method of the present embodiment includes a step of calculating the outer wall heat loss, which is the total heat loss of the facility 5 on the outer wall E1, by multiplying the difference between the set temperature inside the facility 5, which is a building or a moving object, and the outside air temperature, the area of the outer wall E1 of the facility 5, and the heat transfer coefficient of the outer wall E1; and a step of calculating an individual heat load, which is the heat load in each of the plurality of compartments 50 of the facility 5, by performing a process of multiplying the ratio of the size of the target compartment 50 among the plurality of compartments 50 of the facility 5 to the size of the facility 5 and the outer wall heat loss for each of the plurality of compartments 50.

[0012] By the information processing method of this embodiment, an individual heat load can be calculated. The individual heat load corresponds to the magnitude of the air conditioning capacity required for the section 50 of the facility 5 (individual air conditioning heat load). Therefore, by calculating the individual heat load, the designer can grasp the individual air conditioning heat load, and it becomes possible to smoothly proceed with the air conditioning design of the facility 5. For example, the designer may select air conditioning equipment so that the sum of the air conditioning capacities of one or more air conditioning equipment installed in a certain section 50 is equal to or greater than the individual air conditioning heat load of the section 50.

[0013] A program according to one aspect is a program for causing one or more processors of a computer system to execute the above information processing method. The program may be recorded on a non-transitory computer-readable recording medium.

[0014] An example of the building as the facility 5 is a house, an office building, a factory, a complex commercial facility, a library, an art museum, a museum, a play facility, a theme park, a park, an airport, a railway station, a stadium, a hotel, a hospital, etc. An example of the moving body as the facility 5 is a ship, a railway vehicle, an aircraft, etc.

[0015] One room of the facility 5 may correspond to one section 50, or one room may include two or more sections 50. Alternatively, at least a part of the space of each of two or more rooms may be included in one section 50. In this embodiment, it will be described assuming that one room corresponds to one section 50.

[0016] In FIG. 2, the facility 5 includes three sections 50 (three rooms). The adjacent sections 50 are separated by the inner wall I1. Also, the internal space (indoor space) of the facility 5 and the outdoor space outside the facility 5 are separated by the outer wall E1 (the thick line part in FIG. 2). The outer wall E1 includes a side wall along the vertical direction and a ceiling. The three sections 50 are each adjacent to the outdoor space, and the three sections 50 and the outdoor space are separated from each other by a part of the outer wall E1.

[0017] (2) Information processing system The information processing method is realized by an information processing system 1 (see FIG. 3). The information processing system 1 of the present embodiment includes a first calculation unit 21 and a second calculation unit 22. The first calculation unit 21 multiplies the difference between the set temperature and the outside air temperature inside the facility 5 which is a building or a moving body, the area of the outer wall E1 of the facility 5, and the heat transfer coefficient of the outer wall E1 to calculate the outer wall heat loss which is the heat loss of the entire facility 5 in the outer wall E1. The second calculation unit 22 calculates the individual heat load which is the heat load in each of the plurality of sections 50 by performing the process of multiplying the ratio of the size of the section 50 of interest among the plurality of sections 50 of the facility 5 to the size of the facility 5 and the outer wall heat loss for each of the plurality of sections 50.

[0018] More specifically, the information processing system 1 includes a processing unit 2, a communication unit 31, a storage unit 32, an operation unit 33, and a display unit 34. The processing unit 2 includes a first calculation unit 21, a second calculation unit 22, a third calculation unit 23, a selection processing unit 24, an analysis unit 25, and a BIM data creation unit 26.

[0019] The processing unit 2 includes a computer system having one or more processors and a memory. The functions of the processing unit 2 are realized by the processor of the computer system executing a program recorded in the memory of the computer system. The program may be recorded in the memory, may be provided through a telecommunication line such as the Internet, or may be provided by being recorded in a non-temporary recording medium such as a memory card.

[0020] The first calculation unit 21, the second calculation unit 22, the third calculation unit 23, the selection processing unit 24, the analysis unit 25, and the BIM data creation unit 26 merely indicate functions realized by the processing unit 2, and do not necessarily indicate an entity configuration.

[0021] The information processing system 1 is used together with, for example, a data server. The data server includes a storage unit that holds a library 4. The information processing system 1 can receive data included in the library 4 or provide data to the library 4 by communicating with the data server. Note that the library 4 may be provided in the information processing system 1.

[0022] The communication unit 31 of the information processing system 1 includes a communication interface device for communicating with the data server. The communication unit 31 can communicate with the data server via the communication interface device. As used in this disclosure, "can communicate" means that signals can be exchanged directly or indirectly via a network, a repeater, or the like by an appropriate communication method such as wired communication or wireless communication.

[0023] The storage unit 32 stores information related to the processing performed in the information processing system 1.

[0024] The operation unit 33 is an input interface that receives a user's operation. The operation unit 33 includes, for example, a pointing device such as a mouse and a keyboard.

[0026] As described above, the first calculation unit 21 of the processing unit 2 calculates the outer wall heat loss. The second calculation unit 22 calculates the individual heat load.

[0027] The third calculation unit 23 calculates the ventilation heat load. The ventilation heat load is the amount of heat flowing in and out per unit time through the ventilation equipment.

[0029] The analysis unit 25 simulates the environment of the facility 5 when air conditioning equipment is installed in the facility 5.

[0030] The BIM data creation unit 26 performs a process of adding the BIM data of the air conditioning equipment to be installed in the facility 5 to the pre-prepared BIM (Building Information Modeling) data of the facility 5.

[0031] (3) Details of the information processing method Hereinafter, with reference to FIG. 1, the details of the information processing method will be described. Note that the sequence shown in FIG. 1 is merely an example of the information processing method according to the present disclosure, and the order of processing may be appropriately changed, or processing may be appropriately added or omitted.

[0032] (3.1) Input of environmental information First, environmental information is input into the information processing system 1 (step ST1). The environmental information is information regarding the air conditioning environment of the facility 5. The environmental information includes information such as the area of the outer wall E1 of the facility 5, the heat transfer coefficient of the outer wall E1, and the size of each of the plurality of compartments 50 of the facility 5. A part of the environmental information is provided to the information processing system 1 as BIM data.

[0033] More specifically, the library 4 includes the BIM data 41 (see FIG. 3) of the facility 5, and this BIM data 41 is provided to the information processing system 1. The BIM data 41 includes the three-dimensional model data of the facility 5 and the data of the materials of each member constituting the facility 5. The information processing system 1 can calculate the heat transfer coefficient of the outer wall E1 based on, for example, the data of the material of the outer wall E1. Alternatively, the information on the heat transfer coefficient of the outer wall E1 may be provided from the library 4.

[0034] The environmental information further includes the information on the set temperature inside Facility 5 and the information on the outside air temperature. For example, the information processing system 1 sets the temperature specified by the user operating the operation unit 33 as the set temperature. For the outside air temperature, for example, when the user operates the operation unit 33 to select the area where Facility 5 is located, the average temperature at a specific time in the area (for example, summer or winter) is read from the storage unit 32, and the information processing system 1 sets the read temperature as the outside air temperature.

[0035] The environmental information further includes the information on the ventilation equipment installed in Facility 5. The information on the ventilation equipment includes, for example, the installation location of the ventilation equipment, the flow rate of the ventilation equipment, and the information on the heat exchange rate of the ventilation equipment.

[0036] In addition, as the heat loss of Facility 5, there is also heat loss other than the heat loss due to the passage of heat through the outer wall E1 and the heat loss due to the passage of heat through the ventilation equipment. The environmental information further includes the information on various heat losses. Specifically, the environmental information includes the information on the calorific value of the human body present in Compartment 50, the calorific value of the equipment installed in Compartment 50, and the heat quantity corresponding to the solar radiation amount from the window installed in Compartment 50.

[0037] (3.2) Calculation of Outer Wall Heat Loss After the environmental information is input into the information processing system 1, the first calculation unit 21 calculates the outer wall heat loss (step ST2). Let the outer wall heat loss be Qi (unit: [W]), the outside air temperature be Te (unit: [°C]), the set temperature inside Facility 5 be Tr (unit: [°C]), the area of the outer wall E1 be Ae (unit: [m 2 )), and the heat transfer coefficient of the outer wall E1 be K (unit: [W / (m 2 ·K)]), then the outer wall heat loss Qi is obtained by [Equation 1]. [Equation 1] Qi = K × Ae × (Te - Tr) Let Ro, Rw, and Ri (unit: [m 2 ·K / W]) be the thermal resistance of the outer surface of the outer wall E1, the thermal resistance of the outer wall E1, and the thermal resistance of the inner surface of the outer wall E1, respectively. Then, the heat transfer coefficient K is obtained by [Equation 2]. [Equation 2] K = 1 / (Rо + Rw + Ri) The set temperature Tr may be a temperature common to all compartments 50. For example, the average value of the set temperatures of each compartment 50 may be used as the set temperature Tr applied to [Equation 1]. Also, the area of the outer wall E1 may be an approximately determined area. For example, in FIG. 2, the value obtained by multiplying the length of the thick line representing the outer wall E1 by a certain height may be used as the area of the side wall of the outer wall E1, and the sum of the area of the side wall and the area of the ceiling may be used as the area of the outer wall E1.

[0038] (3.3) Calculation of individual heat loads ≪3.3.1≫ First example Next, the second calculation unit 22 calculates the individual heat load (step ST3). In the first example, the minimum processing for calculating the individual heat load will be described.

[0039] The second calculation unit 22 performs a process of multiplying, for each of the plurality of compartments 50 of the facility 5, the ratio of the size of the target compartment 50 to the size of the facility 5 and the outer wall heat loss. Thereby, the second calculation unit 22 calculates the heat load (individual heat load) in each of the plurality of compartments 50.

[0040] Regarding the facility 5 and the compartment 50, the "size" may be the volume or the floor area. Also, when the "size" is the volume, the value obtained by multiplying the floor area by a certain height may be approximately used as the volume. In the present embodiment, the "size" is defined as the floor area.

[0041] For example, assume that the floor area of the first compartment 50 among the three compartments 50 constituting the facility 5 occupies 20% of the sum of the floor areas of the three compartments 50. In this case, the individual heat load corresponding to the first compartment 50 is a value 0.2 times the outer wall heat loss. Similarly, for the second compartment 50 and the third compartment 50, the corresponding individual heat loads are calculated.

[0042] Hereinafter, the value obtained by multiplying the outer wall heat loss by the ratio of the size of the section 50 is referred to as the individual outer wall heat loss. As described above, the individual heat load is the heat load in each of the plurality of sections 50. In the first example, the individual outer wall heat loss coincides with the individual heat load, but in the following second and third examples, they do not coincide.

[0043] ≪3.3.2≫ Second Example Hereinafter, additional processing for calculating the individual heat load will be described.

[0044] The third calculation unit 23 calculates the ventilation heat load for each section 50. The ventilation heat load is the amount of heat flowing in and out per unit time through the ventilation equipment. The third calculation unit 23 calculates the ventilation heat load by multiplying the difference between the set temperature of the room temperature and the outside air temperature, the flow rate in the ventilation equipment installed in the facility 5, and a predetermined coefficient. The second calculation unit 22 adds the ventilation heat load calculated by the third calculation unit 23 to the individual heat load of the first example in the section 50 where the ventilation equipment is installed among the plurality of sections 50. That is, the sum of the individual outer wall heat loss and the ventilation heat load is the individual heat load of the second example.

[0045] Let the ventilation heat load be Qv (unit: [W]), the flow rate in the ventilation equipment be q (unit: [m 3 / s]), the density of air be ρ (= 1.18 [kg / m 3 ), and the specific heat at constant pressure of air be c (= 1005 [J / (kg·K)]). Then, the ventilation heat load Qv is obtained by [Equation 3]. [Equation 3] Qv = ρ × c × q × (Te - Tr) ρ × c is the above-mentioned predetermined coefficient. The predetermined coefficient may be changed as appropriate.

[0046] ≪3.3.3≫ Third Example Hereinafter, further additional processing for calculating the individual heat load will be described.

[0047] The second calculation unit 22 acquires information regarding a value to be added to the individual heat load of the first example. The information is included in the environmental information acquired in step ST1. The information is generated, for example, based on information input by the user operating the operation unit 33.

[0048] The value to be added to the individual heat load of the first example is at least one of the calorific value of the human body, the calorific value of equipment, and the calorific value corresponding to the solar radiation amount. That is, the second calculation unit 22 adds at least one of the calorific value per unit time of the human body (first calorific value) existing in the target section 50 among the plurality of sections 50, the calorific value per unit time of the equipment installed in the target section 50 (second calorific value), and the calorific value per unit time corresponding to the solar radiation amount from the window installed in the target section 50 (third calorific value) to the individual heat load of the first example to calculate the individual heat load of the third example.

[0049] For example, assume that the maximum occupancy of the first section 50 or the number of occupants set by the user operating the operation unit 33 is 4 people. The calorific value per unit time per person is pre-stored in the storage unit 32. The second calculation unit 22 uses the value obtained by multiplying the calorific value per person by the number of people (4 people) as the first calorific value of the first section 50.

[0050] Also, for example, the calorific value per unit time of the equipment (second calorific value) installed in the first section 50 is information set by the user operating the operation unit 33, for example, or information included in the BIM data 41 of the facility 5 provided from the library 4. Examples of equipment include lighting equipment, personal computers, and printers, etc.

[0051] Further, for example, the user operates the operation unit 33 to select the area where the facility 5 is located. Thereby, the solar radiation amount in the area is specified. Further, the BIM data 41 of the facility 5 provided from the library 4 includes information on the window area, window orientation, and light transmittance of the window of the facility 5. Based on these pieces of information, the second calculation unit 22 obtains the solar radiation amount from the window installed in the first section 50. Further, the second calculation unit 22 obtains the amount of heat per unit time (third heat generation amount) corresponding to the solar radiation amount.

[0052] Let I (unit: [W / m 2 ) be the solar radiation amount (incident light amount) on the window surface, Aw (unit: [m 2 ) be the window area, and τ be the light transmittance of the window. Then, the third heat generation amount Qw is obtained by [Equation 4]. [Equation 4] Qw = I × Aw × τ The second calculation unit 22 sets the sum of the first heat generation amount, the second heat generation amount, the third heat generation amount, the ventilation heat load, and the individual outer wall heat loss in the first section 50 as the individual heat load of the first section 50. Similarly for the second and third sections 50, the second calculation unit 22 acquires the first heat generation amount, the second heat generation amount, the third heat generation amount, and the ventilation heat load, and adds these to the individual heat load (individual outer wall heat loss) in the first example.

[0053] Note that the value added to the individual heat load in the first example does not have to be all of the first heat generation amount, the second heat generation amount, the third heat generation amount, and the ventilation heat load. That is, for each section 50, a value obtained by adding at least one of the first heat generation amount, the second heat generation amount, the third heat generation amount, and the ventilation heat load to the individual outer wall heat loss may be set as the individual heat load in the third example.

[0054] (3.4) Individual air-conditioning heat load Further, the information processing method of the present embodiment further includes a step of calculating an individual air-conditioning heat load based on the individual heat load. The individual air-conditioning heat load is the magnitude of the air-conditioning capacity required for the air-conditioning equipment in each of the plurality of sections 50. In the present embodiment, the individual heat load is equal to the individual air-conditioning heat load.

[0055] (3.5) Process of determining candidates for air-conditioning equipment to be installed After the individual heat load (individual air-conditioning heat load) is calculated, the information processing system 1 provides numerical information representing the individual heat load to the data server (step ST4). In the library 4 of the data server, various air-conditioning devices that can be installed in the facility 5 are registered, and the library 4 contains information on each air-conditioning device. The data server searches for air-conditioning devices that meet the conditions from those registered in the library 4 (step ST5). The air-conditioning devices that meet the conditions are treated as candidates for the air-conditioning devices to be installed in the facility 5. The conditions include, for example, when the number of air-conditioning devices installed in a certain section 50 is N (N is a natural number), the total air-conditioning capacity of the N air-conditioning devices is equal to or greater than the individual heat load. Thus, the information processing method of the present embodiment further includes a selection step (step ST5) of determining candidates for air-conditioning devices installed in each of the plurality of sections 50 based on the individual heat load. In the selection step, candidates for air-conditioning devices installed in each of the plurality of sections 50 are determined from among the plurality of air-conditioning devices registered in the library 4.

[0056] Information on the air-conditioning devices determined as candidates is provided from the library 4 to the information processing system 1. That is, the information processing method of the present embodiment further includes a step ST6 of acquiring information on the air-conditioning devices from the library 4. The information on the air-conditioning devices includes information on the product number of the air-conditioning device, the size, at least one of the cooling rated capacity and the heating rated capacity, the air volume for each air volume setting value, and the air direction range.

[0057] The information on the size of the air-conditioning device includes, for example, information on the overall width, height, and depth dimensions of the air-conditioning device, as well as the dimensions of the air inlet and outlet. The cooling rated capacity and the heating rated capacity represent the rated value of the amount of heat transferred by the air-conditioning device per unit time (unit: [W]). The air volume setting value is, for example, three values corresponding to "strong", "medium", and "weak". The air direction range represents the change range of the air supply direction of the air-conditioning device, and the unit is radian. The air direction range may be one range representing the change range of the air supply direction around one axis, or two or three ranges representing the change ranges of the air supply direction around two or three axes, respectively.

[0058] In addition, the information about the air conditioner includes, for example, the URL (Uniform Resource Locator) of the website where the product information of the air conditioner can be downloaded, the installation method of the air conditioner, and the information about the special functions of the air conditioner (for example, the sterilization function or the deodorization function). In addition, the information about the air conditioner includes, for example, the horsepower of the air conditioner, the heating COP (Coefficient Of Performance), the cooling COP, the external static pressure, the type of available power supply, the operating current, the rated power consumption, the power factor, the operating noise (SPL: Sound Pressure Level), and the information about the mass of the air conditioner.

[0059] (3.6) Selection and Placement After the information processing system 1 acquires the information about the air conditioner in step ST6, the selection processing unit 24 (see FIG. 3) performs a process of selecting an air conditioner and a process of placing the air conditioner on the BIM data of the facility 5 according to the user's operation (step ST7).

[0060] More specifically, first, an image representing a plurality of sections 50 is displayed on the display unit 34. The user selects the section 50 to be subjected to air conditioning design by operating the operation unit 33. Then, information about one or more air conditioners that are candidates for the air conditioner to be installed in the section 50 is displayed on the display unit 34. The information about the air conditioner is, for example, information about the product number of the air conditioner, the size, at least one of the cooling rated capacity and the heating rated capacity, the air volume for each air volume setting value, the wind direction range, and an image (photo) of the air conditioner. The user selects the air conditioner to be installed in the section 50 by operating the operation unit 33. Next, the user places the air conditioner at a desired position on the BIM data of the facility 5 by operating the operation unit 33. Thereby, the selection processing unit 24 performs a process of determining the selection and placement of the air conditioner to be installed in the section 50.

[0061] The user selects and places the air conditioner to be installed for all the sections 50.

[0062] (3.7) Environmental simulation Next, the analysis unit 25 (see FIG. 3) performs environmental simulation (step ST8) based on the arrangement of the air conditioning equipment set by the user in step ST7, the air conditioning capacity (cooling rated capacity and heating rated capacity) and the wind direction range of the air conditioning equipment, and the BIM data of the facility 5, etc. That is, the information processing method of the present embodiment further includes step ST8 of simulating the environment of the facility 5 when the air conditioning equipment is installed in the facility 5 based on the information regarding the air conditioning equipment and the structural data (BIM data) of the facility 5.

[0063] Specifically, first, the user sets the environmental conditions required for the section 50. The environmental conditions include, for example, the maximum wind speed, average wind speed, wind direction at a predetermined position, PMV (Predicted Mean Vote), and PPD (Predicted Percentage of Dissatisfied) of the section 50. Further, the environmental conditions include the information on the set temperature of the section 50 among the environmental information acquired in step ST1. The analysis unit 25 performs environmental simulation on each of the plurality of sections 50 on the premise of performing various settings of the air conditioning equipment so as to approach the environmental conditions.

[0064] The environmental simulation executed by the analysis unit 25 is a CFD (Computational Fluid Dynamics) simulation. As a result of the environmental simulation, for example, information on the temperature distribution and air volume distribution in the section 50 is generated. The temperature distribution is represented, for example, by color-coding the space according to the temperature level in a three-dimensional image representing the section 50. Further, the air volume distribution is represented, for example, by color-coding the space according to the air volume magnitude in a three-dimensional image representing the section 50. Further, as a result of the environmental simulation, for example, predicted values of PMV and PPD in the section 50 are generated.

[0065] The user views the results of the environmental simulation displayed on the display unit 34. If the results of the environmental simulation are satisfactory, the user approves the selection and arrangement of the air conditioning equipment in the compartment 50 by operating the operation unit 33 (step ST9: Yes). On the other hand, if the results of the environmental simulation are not satisfactory (step ST9: No), the user redoes the selection and arrangement of the air conditioning equipment. That is, the process returns to step ST7.

[0066] (3.8) BIM Data Creation When the user approves the selection and arrangement of the air conditioning equipment in the compartment 50 and performs an operation to confirm the selection and arrangement on the operation unit 33, the BIM data creation unit 26 (see FIG. 3) creates BIM data of the facility 5 including the BIM data of the air conditioning equipment. That is, the information processing method of the present embodiment further includes step ST10 of adding the BIM data of the air conditioning equipment to the BIM data of the facility 5. The BIM data created thereby includes three-dimensional model data of the structural part of the facility 5 and three-dimensional model data of the air conditioning equipment installed in the structural part (for example, a wall). Further, the BIM data includes information regarding the air conditioning equipment (for example, information on air conditioning capacity and wind direction range). The user can obtain information regarding the air conditioning equipment from the BIM data by operating the operation unit 33.

[0067] The information processing system 1 provides the BIM data 41 (see FIG. 3) created in step ST10 and the results of the environmental simulation (analysis data 42) executed in step ST8 to the library 4 (step ST11). The library 4 holds the BIM data 41 and the analysis data 42.

[0068] The administrator of the facility 5 can manage the facility 5 using the BIM data 41 held in the library 4. For example, the administrator can grasp the arrangement and specifications of the air conditioning equipment by referring to the BIM data 41. Further, the administrator can grasp the air conditioning environment (temperature distribution, air volume distribution, etc.) of each of the plurality of compartments 50 by referring to the analysis data 42 held in the library 4.

[0069] (Modification Example 1) Hereinafter, the information processing method according to Modification Example 1 will be described. For the same configurations as those in the embodiment, the same reference numerals will be given and the description thereof will be omitted.

[0070] In the embodiment, for example, when the user operates the operation unit 33 to select the area where the facility 5 exists, the average temperature in a specific period (for example, summer or winter) of the area is read from the storage unit 32, and the information processing system 1 sets the read temperature as the outside air temperature Te. Then, according to [Equation 1], the outer wall heat loss Qi is obtained using the outside air temperature Te. In this Modification Example 1, the method for determining the outside air temperature Te is different between when the air conditioner is in the cooling operation and when it is in the heating operation. Whether the air conditioner performs the cooling operation or the heating operation is specified by the user operating the operation unit 33.

[0071] In this Modification Example 1, the temperature read from the storage unit 32 is referred to as the actual outside air temperature t0 (unit: [°C]). Let a0 be the solar radiation absorption rate on the surface of the outer wall E1 、 Let Ie (unit: [W / m 2 ) be the solar radiation amount (incident light amount) on the surface of the outer wall E1, and let α (unit: [W / (m 2 ·K)]) be the overall heat transfer coefficient on the surface of the outer wall E1. Also, let F be the form factor for viewing the sky from the outer surface of the outer wall E1 (0.5 for the side wall along the vertical direction and 1 for the ceiling), let σ (= 5.67×10 -8 [W / (m 2 ·K 4 )]) be the radiation constant of a black body, and let T0 be the value obtained by converting the actual outside air temperature t0 to the absolute temperature.

[0072] The outside air temperature Te when the air conditioner is in the cooling operation is obtained by [Equation 5]. [Equation 5] Te = t0 + a0×Ie / α The outside air temperature Te when the air conditioner is in the heating operation is obtained by [Equation 6]. [Equation 6] Te = t0 - F×σ×T0 4 / α That is, in the first modification example, when the air conditioning equipment is in the cooling operation, the outside air temperature Te is increased by an amount corresponding to the influence of solar radiation, and when the air conditioning equipment is in the heating operation, the outside air temperature Te is decreased by an amount corresponding to the blackbody radiation of the facility 5. Thereby, the air conditioning design of the facility 5 can be performed more precisely.

[0073] By substituting the outside air temperature Te obtained by [Equation 5] or [Equation 6] into [Equation 1], the outer wall heat loss Qi can be obtained.

The following modification examples may be realized in appropriate combinations. Further, the following modification examples may be realized in appropriate combination with the above-described modification example 1.

In this case, for each section 50 that is an object for which the individual heat load is calculated, the heat loss due to heat transfer between the section 50 and the space where the air conditioning equipment is not installed may be added to the individual heat load of the section 50.

Information regarding the candidates for the ventilation equipment is provided to the information processing system 1, and the user can select the ventilation equipment to be actually installed from among the candidates for the ventilation equipment and determine the arrangement.

Further, the information processing system 1 may perform a process of presenting to the user the recommended arrangement for the air conditioner. For example, the information processing system 1 may obtain the air conditioner and its arrangement that maximize the air conditioning efficiency and present them to the user.

Further, at least some functions of the information processing system 1, for example, at least some functions of the analysis unit 25 may be realized by a cloud (cloud computing) or the like.
