Abstract

The present disclosure addresses the problem of setting driving conditions for an air conditioner such that a specific space becomes a desired PMV space. This setting method has a space analysis step, an environment calculation step, a determination step, and a change step. In the space analysis step, a space analysis is carried out. In the environment calculation step, the average temperature and average air speed in a specific space (15) are determined on the basis of the space analysis result. In the determination step, a determination regarding whether to change the driving conditions of an air conditioner (19) is made on the basis of the space analysis result. When the determination in the determination step is made that the driving conditions should be changed, the driving conditions of the air conditioner (19) are changed in the change step on the basis of a relation between a target temperature+target air speed and the average temperature+average air speed determined in the environment calculation step. This setting method repeats the space analysis step and the determination step, on the basis of the changed driving conditions.

Summary of the Invention

[0004] In a system as described in Patent Document 1, in order to realize a comfortable indoor space (specific space), it is desired that the specific space becomes a desired PMV space.

[0005] In view of the above reasons, the present disclosure is made, and an object thereof is to provide a setting method, a program, and a setting system capable of setting driving conditions of air-conditioning equipment so that a specific space becomes a desired PMV space.

[0006] A setting method according to one aspect of the present disclosure comprises a spatial analysis step, an environmental calculation step, a determination step, and a modification step. In the spatial analysis step, a spatial analysis is performed based on the driving conditions of an air conditioning unit installed in an indoor space and information on the installation location of the air conditioning unit. In the environmental calculation step, the average temperature and average wind speed of a specific space in the indoor space are determined based on the results of the spatial analysis. In the determination step, a determination is made based on the results of the spatial analysis whether or not to change the driving conditions of the air conditioning unit. In the modification step, if it is determined in the determination step that the driving conditions should be changed, the driving conditions of the air conditioning unit are changed based on a predetermined relationship between a target temperature and target wind speed, which are set in advance so that the specific space becomes a desired PMV space, and the average temperature and average wind speed obtained in the environmental calculation step. After changing the driving conditions of the air conditioning unit in the modification step, the setting method repeats the spatial analysis step and the determination step based on the modified driving conditions. A setting method according to one aspect of the present disclosure comprises a spatial analysis step, an environmental calculation step, a determination step, and a modification step. In the spatial analysis step, a spatial analysis is performed based on the operating conditions, including the set temperature, of an air conditioning unit installed in an indoor space, and information on the installation location of the air conditioning unit. In the environmental calculation step, the average temperature and average wind speed of a specific space in the indoor space are determined based on the results of the spatial analysis. In the determination step, a determination is made based on the results of the spatial analysis whether or not to change the operating conditions of the air conditioning unit. In the modification step, if it is determined in the determination step to change the operating conditions, a target temperature is determined so that the specific space becomes a desired PMV space, and based on a predetermined relationship between the average temperature and the average wind speed determined in the environmental calculation step, only the set temperature among the operating conditions of the air conditioning unit is changed so that the average temperature becomes the target temperature. After changing the operating conditions of the air conditioning unit in the modification step, the setting method repeats the spatial analysis step and the determination step based on the modified operating conditions.

The determination unit determines whether or not to change the driving conditions of the air conditioning equipment based on the results of the spatial analysis performed by the spatial analysis unit. If the determination unit determines that the driving conditions should be changed, the modification unit changes the driving conditions of the air conditioning equipment based on a predetermined relationship between a target temperature and target wind speed that have been set in advance so that the specific space becomes a desired PMV space, and the average temperature and average wind speed determined by the environmental calculation unit. A setting system according to one aspect of this disclosure comprises a spatial analysis unit, an environmental calculation unit, a determination unit, and a modification unit.

[0010] Preferred embodiments of this disclosure will be described in detail below with reference to the drawings. In the embodiments described below, elements common to each other are denoted by the same reference numerals, and redundant descriptions of common elements may be omitted. The embodiments described below are merely one of many embodiments of this disclosure. Embodiments can be modified in various ways depending on the design, etc., as long as the objectives of this disclosure are achieved. The figures described in this disclosure are schematic diagrams, and the ratios of the size and thickness of each component in each figure do not necessarily reflect the actual dimensional ratios. The arrows indicating directions in the drawings are examples only and are not intended to define the direction in which the setting system 1 is used. Furthermore, the arrows indicating directions in the drawings are for illustrative purposes only and do not represent actual objects.

[0011] In this disclosure, "perpendicular" means not only a state where the angle between two objects is exactly 90 degrees, but also a state where the two objects are approximately orthogonal within a certain margin of error. In other words, the angle between two orthogonal objects falls within a certain margin of error (for example, 10 degrees or less) relative to 90 degrees.

[0012] In the embodiment, where "less than or equal to" is used in the comparison of two values ​​such as measurement data, it may also be used as "less than". In other words, whether or not the case where the two values ​​are equal is included in the comparison of two values ​​can be arbitrarily changed depending on the setting of the reference value, etc., so there is no technical difference between "less than or equal to" and "less than". Similarly, where "greater than or equal to" is used, it may also be used as "greater than".

[0013] (1) Overview First, an overview of the setting system 1 and setting method according to this embodiment will be described with reference to Figures 1 and 2. The setting system 1 is a system that executes the setting method.

[0014] In the setting method of the present embodiment, for example, the driving conditions of the air-conditioning equipment 19 (see FIG. 2) provided in the indoor space 10 are set so that a specific space 15 (see FIG. 2) in the internal space of a facility such as the indoor space 10 (see FIG. 2) becomes a desired PMV space. The air-conditioning equipment 19 is, for example, an air conditioner that performs cooling operation or heating operation. The setting method is performed, for example, at the time of designing the facility or the like.

[0015] Note that the "specific space" referred to in the present disclosure is a space in the indoor space 10 that is, for example, 0.1 m or more and 1.7 m or less above the floor and is 1 m or more away from each of a plurality of wall surfaces 11 (see FIG. 2) provided in the indoor space 10.

[0016] "PMV" referred to in the present disclosure is an index indicating the degree quantitatively representing the warm and cold feeling felt by a human. The specific value of PMV (PMV value) is calculated from four physical quantities of temperature (room temperature), radiant temperature (radiation temperature), humidity (relative humidity), and wind speed, and two human factor quantities of the clothing amount and activity amount (work amount) of the occupants in the room. The PMV value takes a value in the range of -3 to +3. The larger the PMV value on the negative side, the colder the environment a human feels. On the other hand, the larger the PMV value on the positive side, the hotter the environment a human feels. Generally, the closer the PMV value is to zero, the more comfortable the user can feel. PMV, including the calculation method, conforms to, for example, the standard of ISO7730 (Third edition 2005-11-15).

[0017] The "desired PMV space" referred to in the present disclosure is a space in which the ratio (hereinafter, PMV space volume ratio) occupied by a region (space) where the PMV value is within a predetermined range is equal to or more than a predetermined ratio. For example, in the present embodiment, the target PMV space volume ratio is 90%. The predetermined range of the PMV value is -0.5 to 0.5 (the range of -0.5 or more and 0.5 or less). Note that the predetermined ratio and the predetermined range can be changed as appropriate.

[0018] As used in this disclosure, the "facility" includes residential facilities used for residential purposes, as well as non-residential facilities such as stores (tenants), offices, welfare facilities, educational facilities, hospitals, and factories. Non-residential facilities also include restaurants, amusement arcades, hotels, inns, kindergartens, nurseries, community centers, etc. That is, the facility may be a residential facility such as an apartment, or a non-residential facility such as an office building. Furthermore, the facility also includes a facility in a mixed state of a residential facility and a non-residential facility, for example, a facility where the lower floors are stores and the upper floors are residential units. In this embodiment, it is assumed that the facility is an office building and the indoor space 10 is one room of an office such as a conference room.

[0019] The setting terminal 2 is an example of the setting system 1. As shown in FIG. 1, the setting terminal 2 of this embodiment includes a space analysis unit 63, an environment calculation unit 64, a determination unit 65, and a change unit 66.

[0020] The space analysis unit 63 performs a space analysis process (space analysis step). In the space analysis step, a space analysis is performed based on the driving conditions of the air conditioning equipment 19 provided in the indoor space 10 and the information on the installation position of the air conditioning equipment 19.

[0021] The environment calculation unit 64 performs an environment calculation process (environment calculation step). In the environment calculation step, based on the result of the space analysis by the space analysis unit 63 (in the space analysis step), the average temperature and average wind speed of the specific space 15 (see FIG. 2) in the indoor space 10 are obtained.

[0022] The determination unit 65 performs a determination process (determination step). In the determination step, based on the result of the space analysis by the space analysis unit 63 (in the space analysis step), it is determined whether or not to change the driving conditions of the air conditioning equipment 19.

[0023] The modification unit 66 performs a modification process (modification step) when the determination unit 65 determines (in the determination step) that the driving conditions of the air conditioning equipment 19 should be changed. In the modification step, the driving conditions of the air conditioning equipment 19 are changed based on a predetermined relationship between the target temperature and target wind speed, which are set in advance so that the specific space 15 becomes a desired PMV space, and the average temperature and average wind speed, which are determined (in the environmental calculation step) by the environmental calculation unit 64.

[0024] After the modification unit 66 changes the driving conditions of the air conditioning equipment 19 (in the modification step), the spatial analysis unit 63 and the determination unit 65 repeat the spatial analysis step and the determination step based on the modified driving conditions.

[0025] The setting system 1 and setting method of this embodiment change the driving conditions of the air conditioning equipment 19 based on a predetermined relationship between the target temperature and target wind speed and the average temperature and average wind speed obtained in the environmental calculation step, for example, when the specific space 15 is not a desired PMV space. Therefore, according to the setting system 1 and setting method of this embodiment, the driving conditions of the air conditioning equipment 19 can be set so that the specific space 15 becomes a desired PMV space.

[0026] Furthermore, the specific space 15 in this embodiment is a space within the indoor space 10 that is highly likely to be occupied by people. In other words, according to the setting system 1 and setting method of this embodiment, a space within the indoor space 10 that is highly likely to be occupied by people can be designated as the desired PMV space, thereby providing a comfortable space for people using the indoor space 10.

[0027] (2) Details The detailed configuration of the configuration system 1 (configuration terminal 2) according to this embodiment will be described below with reference to Figures 1 to 6. The configuration terminal 2 is an information terminal such as a desktop or laptop personal computer, a server computer, or a tablet terminal. The configuration terminal 2 is a terminal operated by a user, such as an employee of a design (management) company that designs (manages) a facility.

[0028] As shown in Figure 1, the setting terminal 2 comprises a storage unit 3, a display unit 4, an operation unit 5, and a control unit 6.

[0029] The configuration terminal 2 includes, for example, a microcomputer having a processor and memory. The computer system functions as the control unit 6 by the processor executing one or more appropriate programs. In other words, the control unit 6 is realized in a computer system having a processor and memory. Each of the one or more programs may be pre-recorded in memory, or may be provided via a telecommunication line such as the Internet, or recorded on a non-temporary recording medium such as a memory card.

[0030] The storage unit 3 is a semiconductor memory such as ROM (Read Only Memory), RAM (Random Access Memory), or EEPROM (Electrically Erasable Programmable Read Only Memory). Note that the storage unit 3 is not limited to semiconductor memory; it may also be a hard disk drive or the like. In this embodiment, the storage unit 3 stores target value information.

[0031] The target value information includes information on the target temperature and target wind speed, which are set in advance so that the specific space 15 (see Figure 2) becomes the desired PMV space. The target temperature and target wind speed are values ​​such that the specific space 15 becomes the desired PMV space when the average temperature of the specific space 15 is the target temperature and the average wind speed of the specific space 15 is the target wind speed. In this embodiment, the target temperature and target wind speed are values ​​such that the PMV value of the specific space 15 becomes zero when the average temperature of the specific space 15 is the target temperature and the average wind speed of the specific space 15 is the target wind speed.

[0032] In this disclosure, the independent environmental variables involved in calculating the PMV value are temperature and wind speed. Humidity is assumed to be a fixed value (e.g., 30%RH, 50%RH). In this embodiment, it is assumed that the humidity in the specific space 15 is uniform. In this embodiment, it is also assumed that the radiant temperature of the specific space 15 is equal to the temperature of the specific space 15. In general, in highly insulated houses, the difference between radiant temperature and temperature is small, and approximating radiation with temperature has little effect on the PMV value. Clothing amount and activity level are also fixed. For example, fixed values ​​are used for both cooling and heating. For example, the humidity of the specific space 15, clothing amount, and activity level are preset by the user before the determination step. The fixed value information regarding humidity, clothing amount, and activity level preset by the user is stored, for example, in the storage unit 3. Humidity, clothing amount, and activity level may be preset by the user before the spatial analysis step.

[0033] The target value information in this embodiment is, for example, a comparison table that associates the temperature and wind speed values ​​of a specific space 15 with the PMV value of the specific space 15, when humidity, clothing amount, and activity level are fixed.

[0034] The display unit 4 is, for example, a liquid crystal display or an organic EL (Electro-Luminescence) display. The display content of the display unit 4 is controlled by the control unit 6.

[0035] The operation unit 5 is a pointing device (mouse, touch panel, touchpad, etc.), a keyboard, etc. The operation unit 5 generates operation signals in response to user operations and outputs the operation signals to the control unit 6.

[0036] The display unit 4 and the operation unit 5 may be a touch panel display in which the display unit 4 and the operation unit 5 are integrally formed.

[0037] As shown in Figure 1, the control unit 6 includes an initial setting unit 61, a position setting unit 62, a spatial analysis unit 63, an environmental calculation unit 64, a determination unit 65, and a modification unit 66.

[0038] The initial setting unit 61 performs an initial condition setting process (initial condition setting step). In the initial condition setting step, the initial conditions for the operation of the air conditioning equipment 19 are set based on the heat load calculation of the indoor space 10. The operation conditions for the air conditioning equipment 19 include at least one of a set temperature and a set wind speed. In this embodiment, an example is given where the set temperature and set wind speed are included in the operation conditions of the air conditioning equipment 19. The set temperature is, for example, the temperature of the air blown out from the air conditioning equipment 19 (outlet temperature). The set wind speed is, for example, the wind speed of the air blown out from the air conditioning equipment 19 (outlet wind speed). According to the setting system 1 and setting method of this embodiment, the initial conditions for the operation of the air conditioning equipment 19 are set based on the heat load calculation of the indoor space 10, making it easier to set appropriate initial conditions.

[0039] Furthermore, the heat load calculation in this embodiment is performed for both cooling and heating (cooling and heating load). In other words, according to the setting system 1 and setting method of this embodiment, the driving conditions of the air conditioning equipment 19 can be set so that the specific space 15 becomes the desired PMV space, regardless of whether the air conditioning equipment 19 is performing cooling or heating operation.

[0040] In the initial condition setting step, for example, a heat load calculation is performed using 3D model data such as BIM (Building Information Modeling) data of the facility, and information on the outside air.

[0041] In addition, during the initial condition setting step, conditions such as the outside temperature, the set temperature of the air conditioning unit 19, and the set airflow rate of the air conditioning unit 19 are set based on user operations.

[0042] The position setting unit 62 performs a position setting process (position setting step). In the position setting step, the installation position of the air conditioning equipment 19 is set based on the position of one or more openings present in the indoor space 10. Here, the installation position means the set position of the air conditioning equipment. In this disclosure, "opening" refers to an opening that connects the indoor space 10 to the outside space. As shown in Figure 2, one or more openings include an entrance / exit 16 of the indoor space 10, an air supply unit 17 (ventilation equipment), an exhaust unit 18 (ventilation equipment), and windows, etc. The indoor space 10 in this embodiment is also provided with four wall surfaces 11. The four wall surfaces 11 include the north wall surface 11, the east wall surface 11, the south wall surface 11, and the west wall surface 11. The east wall surface 11 is provided with an entrance / exit 16 of the indoor space 10. In the following description, when the four wall surfaces 11 are not distinguished, each of the four wall surfaces 11 may be referred to as "wall surface 11".

[0043] According to the setting system 1 and setting method of this embodiment, the installation position of the air conditioning equipment 19 is set based on the position of one or more openings, making it easier to install the air conditioning equipment 19 in an appropriate position.

[0044] In the position setting step of this embodiment, the installation position of the air conditioning equipment 19 is set based on a first vector V1 and a second vector V2. The first vector V1 is a vector indicating the direction of airflow into or out of one or more openings. The second vector V2 is a vector indicating the direction of airflow out of the air conditioning equipment 19. In this embodiment, the second vector V2 is a vector along the normal of each of the multiple wall surfaces 11 on which the air conditioning equipment 19 is installed. In other words, the second vector V2 is a perpendicular vector on each of the multiple wall surfaces 11. Note that the first vector V1 and the second vector V2 in this embodiment are unit vectors. In this disclosure, "wall surface" refers to the interior wall surface of the facility. The multiple wall surfaces 11 may include window surfaces.

[0045] In the position setting step of this embodiment, a first vector V1 and a second vector V2 are set. In the position setting step, the first vector V1 is set according to the combination of one or more openings. In addition, in the position setting step, a plurality of second vectors V2 corresponding to a plurality of wall surfaces 11 provided in the interior space 10 are set.

[0046] As shown in Figure 2, the position setting step for the case where one or more openings include an air supply section 17 and an exhaust section 18 will be described. In the position setting step, when one or more openings include an air supply section 17 and an exhaust section 18, a first vector V1 is set that points from the air supply section 17 to the exhaust section 18. In the position setting step, multiple second vectors V2 are set, which are multiple vertical vectors corresponding to multiple wall surfaces 11 provided in the indoor space 10. Then, in the position setting step, the dot product of the first vector V1 and each of the multiple second vectors V2 is calculated, and the wall surface 11 corresponding to the second vector whose dot product with the first vector V1 is the largest is set as the installation position for the air conditioning equipment 19. In the example in Figure 2, the north wall surface 11 is set as the installation position for the air conditioning equipment 19 in the position setting step.

[0047] According to the setting system 1 and setting method of this embodiment, the efficiency of cooling or heating can be improved by aligning the direction of airflow out of the air conditioner 19 with the direction of airflow entering into one or more openings or the direction of airflow out of one or more openings. The direction of airflow out of the air conditioner 19 is not necessarily parallel to the ceiling surface (horizontal direction). That is, the airflow out of the air conditioner 19 may also have a vertical component. Even if the airflow out of the air conditioner 19 has a vertical component, the efficiency of cooling or heating can be improved by aligning the direction of airflow parallel to the ceiling surface included in the airflow out of the air conditioner 19 with the direction of airflow entering into one or more openings or the direction of airflow out of one or more openings.

[0048] Next, as shown in Figure 3, the position setting step will be described for the case where one or more openings are an air supply unit 17 and an inlet / outlet 16. In the position setting step, when one or more openings are an air supply unit 17 and an inlet / outlet 16, a first vector V1 is set that goes from the air supply unit 17 to the inlet / outlet 16. Specifically, a first vector V1 is set that goes from the air supply unit 17 to the central part 161 of the inlet / outlet 16. In addition, in the position setting step, multiple second vectors V2 are set, which are multiple vertical vectors corresponding to multiple wall surfaces 11 provided in the indoor space 10. Then, in the position setting step, the dot product of the first vector V1 and each of the multiple second vectors V2 is calculated, and the wall surface 11 corresponding to the second vector whose dot product with the first vector V1 is the largest is set as the installation position for the air conditioning equipment 19. In the example in Figure 3, in the position setting step, the north wall surface 11 is set as the installation position for the air conditioning equipment 19.

[0049] Next, as shown in Figure 4, the position setting step will be described for the case where one or more openings are an exhaust section 18 and an inlet / outlet 16. In the position setting step, when one or more openings are an exhaust section 18 and an inlet / outlet 16, a first vector V1 is set that points from the inlet / outlet 16 towards the exhaust section 18. Specifically, the first vector V1 is set that points from the central part 161 of the inlet / outlet 16 towards the exhaust section 18. In the position setting step, multiple second vectors V2 are set, which are multiple vertical vectors corresponding to multiple wall surfaces 11 provided in the indoor space 10. Then, in the position setting step, the dot product of the first vector V1 and each of the multiple second vectors V2 is calculated, and the wall surface 11 corresponding to the second vector whose dot product with the first vector V1 is the largest is set as the installation position for the air conditioning equipment 19. In the example in Figure 4, in the position setting step, the eastern wall surface 11 is set as the installation position for the air conditioning equipment 19.

[0050] Next, as shown in Figure 5, the position setting step for the case where there is one or more openings that form an entrance / exit 16 will be described. In the position setting step, if there is one or more openings that form an entrance / exit 16, a first vector V1 is set that points from the entrance / exit 16 to the outside (the external space of the indoor space 10). Specifically, the first vector V1 is set that points from the central part 161 of the entrance / exit 16 to the outside. In addition, in the position setting step, multiple second vectors V2 are set, which are multiple vertical vectors corresponding to multiple wall surfaces 11 provided in the indoor space 10. Then, in the position setting step, the dot product of the first vector V1 and each of the multiple second vectors V2 is calculated, and the wall surface 11 corresponding to the second vector whose dot product with the first vector V1 is the largest is set as the installation position for the air conditioning equipment 19. In the example in Figure 5, in the position setting step, the west wall surface 11 is set as the installation position for the air conditioning equipment 19.

[0051] The spatial analysis unit 63 performs spatial analysis processing (spatial analysis step). In the spatial analysis step, spatial analysis is performed based on the operating conditions of the air conditioning equipment 19 installed in the indoor space 10 and information on the installation location of the air conditioning equipment 19. The spatial analysis is a thermal simulation using, for example, the finite element method. In the spatial analysis step, environmental information including the distribution of room temperature (temperature) in the indoor space 10 and the distribution of wind speed in the indoor space 10 is generated as a result of the spatial analysis. If the modification step is performed by the modification unit 66, the spatial analysis unit 63 performs spatial analysis processing again based on the modified operating conditions. In other words, the spatial analysis unit 63 performs spatial analysis processing each time the modification step is performed by the modification unit 66.

[0052] The environmental calculation unit 64 shown in Figure 1 performs environmental calculation processing (environmental calculation step). In the environmental calculation step, the average temperature and average wind speed of a specific space 15 in the indoor space 10 are determined based on the results of the spatial analysis. In other words, the environmental calculation unit 64 determines the average temperature and average wind speed of a specific space 15 based on environmental information. In this embodiment, the environmental calculation unit 64 performs the environmental calculation step each time spatial analysis processing is performed by the spatial analysis unit 63. In other words, in this embodiment, the environmental calculation unit 64 performs the environmental calculation step each time a modification step is performed by the modification unit 66.

[0053] The determination unit 65 performs a determination process (determination step). In the determination step, it is determined whether or not to change the driving conditions of the air conditioning equipment 19 based on the results of the spatial analysis. In the determination step of this embodiment, the PMV value and PMV spatial volume ratio of the specific space 15 are determined (PMV calculation process) based on environmental information (results of spatial analysis) and preset clothing amount, activity level, and humidity (fixed value information). In this embodiment, it is assumed that the humidity of the specific space 15 is uniform and the radiant temperature of the specific space 15 is the same as the temperature of the specific space 15. That is, in the determination step of this embodiment, the PMV value and PMV spatial volume ratio of the specific space 15 are determined by assuming that the humidity of the specific space 15 is uniform and the radiant temperature of the specific space 15 is the same as the temperature of the specific space 15. By simplifying some of the multiple parameters used to determine the PMV value of the specific space 15, it is possible to make it easier to determine the PMV value and PMV spatial volume ratio of the specific space 15.

[0054] Then, in the determination step, it is determined whether or not to change the driving conditions of the air conditioning equipment 19 based on the PMV spatial volume ratio of the specific space 15 obtained. The determination unit 65 performs the determination step each time the spatial analysis processing is performed by the spatial analysis unit 63. In other words, the determination unit 65 performs the determination step each time the modification step is performed by the modification unit 66.

[0055] In the determination step, if the specific space 15 is not the desired PMV space, it is determined that the driving conditions of the air conditioning equipment 19 should be changed. That is, in the determination step, if the proportion of space where the PMV value is in the range of -0.5 or more and 0.5 or less (=PMV space volume ratio) is less than 90% of the specific space 15, it is determined that the driving conditions of the air conditioning equipment 19 should be changed. Also, in the determination step, if the specific space 15 is the desired PMV space, it is determined that the driving conditions of the air conditioning equipment 19 should not be changed. That is, in the determination step, if the space where the PMV value is in the range of -0.5 or more and 0.5 or less accounts for 90% or more of the specific space 15, it is determined that the driving conditions of the air conditioning equipment 19 should not be changed.

[0056] According to the setting system 1 and setting method of this embodiment, in order to determine whether or not to change the driving conditions of the air conditioning equipment 19 based on the PMV spatial volume ratio of the specific space 15, the driving conditions of the air conditioning equipment 19 can be changed, for example, if the specific space 15 is not a desired PMV space.

[0057] Furthermore, in the determination step of this embodiment, if the change step has already been performed more than a predetermined number of times, it is determined that the driving conditions of the air conditioning equipment 19 will not be changed. In this embodiment, the case where the predetermined number of times is two is given as an example, but the predetermined number of times may be one or three or more times. According to the setting system 1 and setting method of this embodiment, by determining that the driving conditions of the air conditioning equipment 19 will not be changed if the change step has already been performed more than a predetermined number of times, the time required to set the driving conditions of the air conditioning equipment 19 for a specific space 15 (indoor space 10) that is difficult to make into a desired PMV space can be reduced.

[0058] The modification unit 66 performs a modification process (modification step). In the modification step, if it is determined in the determination step that the driving conditions should be changed, the modification unit modifies the driving conditions of the air conditioning equipment 19 based on a predetermined relationship between the target temperature and target wind speed and the average temperature and average wind speed of the specific space 15 obtained in the environmental calculation step. Specifically, in the modification step, at least one of the driving conditions of the air conditioning equipment 19, namely the set temperature and the set wind speed, is changed. By changing at least one of the set temperature and set wind speed of the air conditioning equipment 19 in the modification step, the specific space 15 can be made to become a desired PMV space. At this time, either the temperature or the wind speed, or both, may be changed, but it is preferable to change only the temperature. This is because, generally, the wind speed in a room should be 0.5 m / s or less so that strong winds do not cause discomfort to people, and there is an upper limit to the wind speed. Also, changing the wind speed significantly changes the airflow distribution in the room. Such changes in airflow affect the temperature distribution in the room and are therefore undesirable for adjusting the PMV value. Therefore, it is desirable to set the wind speed to a small value, such as 0.3 m / s or less, and adjust the temperature to keep the PMV value within a specified range.

[0059] A specific example of changing the set temperature in the change step will be explained with reference to Figure 6. An example will be given where the air conditioning unit 19 is operating in cooling mode.

[0060] Assume that the target temperature for specific space 15 is 25°C and the target wind speed for specific space 15 is 0.1 m / s. Also, assume that in the initial condition setting step, the set temperature of the air conditioning unit 19 is set to 15°C, which is 10°C less than the target temperature, and the set wind speed of the air conditioning unit 19 is set to 0.1 m / s. Furthermore, assume that the average temperature of specific space 15, as determined in the environmental calculation step, was 22°C (see point P1).

[0061] In the modification step, the operating conditions of the air conditioning unit 19 are changed so that the set temperature of the air conditioning unit 19 is equal to the target temperature (25°C) of the specific space 15. The first modification step ends here.

[0062] Assume that in the judgment step performed after the first modification step, it is determined that another modification step is necessary. Furthermore, assume that the average temperature of the specific space 15, as determined in the environmental calculation step performed after the first modification step, was 28°C (see point P2).

[0063] In the second modification step, an approximation formula based on a straight line passing through points P1 and P2 is used to determine the set temperature of the air conditioner 19 so that the average temperature of the specific space 15 reaches the target temperature (25°C) (see point P3). Then, in the second modification step, the driving conditions of the air conditioner 19 are changed so that the set temperature of the air conditioner 19 is the determined set temperature (set temperature at point P3). In the case of Figure 6, in the modification step, the driving conditions of the air conditioner 19 are changed so that the set temperature of the air conditioner 19 is 20°C. Note that the fact that the relationship between the set temperature of the air conditioner 19 and the average temperature of the specific space 15 (relationship between points P1 and P3) can be approximated by a linear equation, as shown in Figure 6, was achieved by utilizing the knowledge gained from thermal simulations.

[0064] According to the setting system 1 and setting method of this embodiment, the average temperature can be made to roughly match the target temperature by performing the change step twice.

[0065] Furthermore, if all of the above processes were to be performed using thermal simulation, for example, the outlet temperature of the air conditioning unit 19 would need to be changed in 0.2°C increments, requiring a total of more than ten calculations. Therefore, the calculation time would be enormous and inefficient.

[0066] In the example above, humidity was kept constant, and the target temperature and wind speed at which the PMV value is nearly zero were extracted from the table. If humidity changes are to be considered when calculating the PMV value, a new table including humidity may be used in addition to the above table.

[0067] (3) Operation of the configuration system Next, the operation of the setting system 1 will be explained with reference to Figures 7 to 9.

[0068] Figure 7 is a flowchart showing the overall operation of the setting system 1 in this embodiment. First, the setting system 1 performs an initial setup process (initial setup step) (S1). In the initial setup step, the initial conditions for the operation of the air conditioning equipment 19 are set based on the heat load calculation of the indoor space 10.

[0069] Next, the setting system 1 performs a position setting process (position setting step) (S2). In the position setting step, the installation position of the air conditioning equipment 19 is set based on the position of one or more openings present in the indoor space 10.

[0070] Next, the setting system 1 performs a spatial analysis process (spatial analysis step) (S3). In the spatial analysis step, a spatial analysis is performed using thermal simulation based on the operating conditions of the air conditioning equipment 19 installed in the indoor space 10 and information on the installation location of the air conditioning equipment 19. In the first spatial analysis process, the spatial analysis is performed based on the initial operating conditions of the air conditioning equipment 19 and information on the installation location. In the second and subsequent spatial analysis processes, the spatial analysis is performed based on the operating conditions set (changed) in the change step and information on the installation location.

[0071] Next, the configuration system 1 performs environmental calculation processing (environmental calculation step) (S4). Based on the results of the spatial analysis, the average temperature and average wind speed of the specific space 15 in the indoor space 10 are determined.

[0072] Next, the setting system 1 performs a PMV calculation process (PMV calculation step) (S5). In the PMV calculation step, the PMV value and PMV spatial volume ratio of the specific space 15 are determined based on environmental information (results of spatial analysis) and pre-set clothing amount, activity level, and humidity (fixed value information).

[0073] Next, the setting system 1 determines whether the specific space 15 is the desired PMV space (S6). If the specific space 15 is the desired PMV space (S6: Yes), the setting system 1 terminates the process. On the other hand, if the specific space 15 is not the desired PMV space (S6: No), the setting system 1 determines whether the driving conditions have already been changed two or more times (S7).

[0074] If the driving conditions have already been changed two or more times (S7:Yes), the setting system 1 determines that it will not perform the change process (S8) and terminates the process. On the other hand, if the driving conditions have not been changed two or more times (S7:No), the setting system 1 performs the change process (S8). In the change process, the driving conditions of the air conditioning equipment 19 are changed using the method described above, based on the target temperature and target wind speed, and the average temperature and average wind speed of the specific space 15 obtained in the environmental calculation step.

[0075] When the operating conditions of the air conditioning equipment 19 are changed, the setting system 1 performs spatial analysis processing (S3) again. Specifically, spatial analysis processing is thermal simulation.

[0076] The flowchart shown in Figure 7 is merely an example; the order of processes may be changed as appropriate, and processes may be added or deleted as needed.

[0077] Figures 8 and 9 are flowcharts showing the processing procedure for the position setting process (S2). First, the position setting unit 62 of the setting system 1 determines whether or not an air supply unit 17 is provided in the indoor space 10 (S11). Here, the air supply unit refers to the part that supplies outside air to the indoor space 10. For example, the position setting unit 62 determines whether or not an air supply unit 17 is provided in the indoor space 10 by referring to BIM model data.

[0078] If the indoor space 10 does not have an air supply unit 17 (S11: No), the process proceeds to step S22 in Figure 9. On the other hand, if the indoor space 10 does have an air supply unit 17 (S11: Yes), the position setting unit 62 determines whether or not the indoor space 10 has an exhaust unit 18 (S12). For example, the position setting unit 62 determines whether or not the indoor space 10 has an exhaust unit 18 by referring to 3D model data. Here, the exhaust unit refers to the part that exhausts air from the indoor space 10 to the outside air.

[0079] If an exhaust unit 18 is provided in the indoor space 10 (S12: Yes), that is, if an air supply unit 17 and an exhaust unit 18 are provided in the indoor space 10 (see Figure 2), the position setting unit 62 sets a first vector V1 that goes from the air supply unit 17 to the exhaust unit 18 (S13).

[0080] Next, the position setting unit 62 sets a second vector V2, which is the perpendicular vector of one of the multiple wall surfaces 11 (S14). The position setting unit 62 calculates the dot product of the first vector V1 and the second vector V2 (S15).

[0081] Next, the position setting unit 62 determines whether or not the vertical vectors of all of the multiple wall surfaces 11 have been set as the second vector V2 (S16). In other words, the position setting unit 62 determines whether or not all of the second vector V2s have been set. If the vertical vectors of all of the wall surfaces 11 have not been set as the second vector V2 (S16: No), the process returns to step S14.

[0082] On the other hand, if the vertical vectors of all wall surfaces 11 are set as the second vector V2 (S16: Yes), the position setting unit 62 sets the wall surface 11 corresponding to the second vector whose dot product with the first vector V1 is the largest among the multiple second vectors as the installation position for the air conditioning equipment 19 (S17). Then, the position setting unit 62 terminates the position setting process (S2). The dot product is proportional to cos(θ), where θ is the angle between the two vectors. Therefore, the closer the orientations of the two vectors are to each other (closer to θ=0), the larger the dot product becomes.

[0083] In the process of step S12, if there is no exhaust section 18 in the indoor space 10 (S12: No), that is, if there is one or more openings, such as an air supply section 17 and an inlet / outlet 16 (see Figure 3), the position setting unit 62 sets a first vector V1 that extends from the air supply section 17 to the central part 161 of the inlet / outlet 16 (S18).

[0084] Next, the position setting unit 62 sets a second vector V2, which is the perpendicular vector of one of the multiple wall surfaces 11 (S19). The position setting unit 62 calculates the dot product of the first vector V1 and the second vector V2 (S20).

[0085] Next, the position setting unit 62 determines whether or not the vertical vectors of all of the multiple wall surfaces 11 have been set as the second vector V2 (S21). If the vertical vectors of all of the wall surfaces 11 have not been set as the second vector V2 (S21: No), the process returns to step S19.

[0086] On the other hand, if the vertical vectors of all wall surfaces 11 are set as the second vector V2 (S21: Yes), the position setting unit 62 sets the wall surface 11 corresponding to the second vector whose dot product with the first vector V1 is the largest among the multiple second vectors as the installation position for the air conditioning equipment 19 (S17). Then, the position setting unit 62 terminates the position setting process (S2).

[0087] In the process of step S22 shown in Figure 9, the position setting unit 62 determines whether or not an exhaust unit 18 is provided in the indoor space 10 (S22).

[0088] If an exhaust unit 18 is provided in the indoor space 10 (S22: Yes), that is, if one or more openings are the exhaust unit 18 and the inlet / outlet 16 (see Figure 4), the position setting unit 62 sets a first vector V1 that extends from the central part 161 of the inlet / outlet 16 toward the exhaust unit 18 (S23).

[0089] Next, the position setting unit 62 sets a second vector V2, which is the perpendicular vector of one of the multiple wall surfaces 11 (S24). The position setting unit 62 calculates the dot product of the first vector V1 and the second vector V2 (S25).

[0090] Next, the position setting unit 62 determines whether or not the vertical vectors of all of the multiple wall surfaces 11 have been set as the second vector V2 (S26). If the vertical vectors of all of the wall surfaces 11 have not been set as the second vector V2 (S26: No), the process returns to step S24.

[0091] On the other hand, if the vertical vectors of all wall surfaces 11 are set as the second vector V2 (S26: Yes), the position setting unit 62 sets the wall surface 11 corresponding to the second vector whose dot product with the first vector V1 is the largest among the multiple second vectors as the installation position for the air conditioning equipment 19 (S17 in Figure 8). Then, the position setting unit 62 terminates the position setting process (S2).

[0092] In step S22, if there is no exhaust unit 18 in the indoor space 10 (S22: No), that is, if one or more openings are only the entrance / exit 16 (see Figure 5), the position setting unit 62 sets a first vector V1 that points from the central part 161 of the entrance / exit 16 toward the outside (S27).

[0093] Next, the position setting unit 62 sets a second vector V2, which is the perpendicular vector of one of the multiple wall surfaces 11 (S28). The position setting unit 62 calculates the dot product of the first vector V1 and the second vector V2 (S29).

[0094] Next, the position setting unit 62 determines whether or not the vertical vectors of all of the multiple wall surfaces 11 have been set as the second vector V2 (S30). If the vertical vectors of all of the wall surfaces 11 have not been set as the second vector V2 (S30: No), the process returns to step S28.

[0095] On the other hand, if the vertical vectors of all wall surfaces 11 are set as the second vector V2 (S30: Yes), the position setting unit 62 sets the wall surface 11 corresponding to the second vector whose dot product with the first vector V1 is the largest among the multiple second vectors as the installation position for the air conditioning equipment 19 (S17 in Figure 8). Then, the position setting unit 62 terminates the position setting process (S2).

[0096] The flowcharts shown in Figures 8 and 9 are merely examples; the order of processing may be changed as appropriate, and processes may be added or deleted as appropriate.

[0097] (4) Variations The following lists some modifications of the above embodiment. The modifications described below can be combined and applied as appropriate.

[0098] Functions equivalent to the setting system 1 (setting terminal 2) or setting method according to the above embodiment may be embodied in a (computer) program or a non-temporary recording medium on which the program is stored. A program according to one embodiment is a program that causes one or more processors to execute the setting method described in the above embodiment.

[0099] The entity executing the configuration system 1 (configuration terminal 2) or configuration method in this disclosure includes a computer system. The computer system mainly consists of a processor and memory as hardware. The processor executes a program recorded in the computer system's memory to realize the function of the entity executing the configuration system 1 or configuration method in this disclosure. The program may be pre-recorded in the computer system's memory, provided via a telecommunications line, or provided on a non-temporary recording medium such as a memory card, optical disk, or hard disk drive that is readable by the computer system. The processor of the computer system consists of one or more electronic circuits including semiconductor integrated circuits (ICs) or large-scale integrated circuits (LSIs). The integrated circuits referred to here, such as ICs or LSIs, are named differently depending on the degree of integration and include integrated circuits called system LSIs, VLSIs (Very Large Scale Integration), or ULSIs (Ultra Large Scale Integration). Furthermore, FPGAs (Field-Programmable Gate Arrays) that are programmed after the manufacture of LSIs, or logic devices that allow for the reconfiguration of junction relationships or circuit compartments within LSIs, can also be used as processors. Multiple electronic circuits may be integrated onto a single chip or distributed across multiple chips. Multiple chips may be integrated onto a single device or distributed across multiple devices. The computer system referred to here includes a microcontroller having one or more processors and one or more memories. Therefore, the microcontroller also consists of one or more electronic circuits, including semiconductor integrated circuits or large-scale integrated circuits.

[0100] Furthermore, it is not essential for the configuration system 1 to have multiple functions integrated into a single enclosure (configuration terminal 2); the components of the configuration system 1 may be distributed across multiple enclosures. Moreover, at least some of the functions of the configuration system 1, for example, some of the functions of the configuration terminal 2, may be implemented by the cloud (cloud computing), etc.

[0101] The setting system 1 (setting terminal 2) only needs to include at least a spatial analysis unit 63, an environmental calculation unit 64, a determination unit 65, and a modification unit 66.

[0102] In the above embodiment, an example was given in which the environmental calculation unit 64 performs the environmental calculation step and the determination unit 65 performs the PMV calculation step. However, the spatial analysis unit 63 may perform at least one of the environmental calculation step and the PMV calculation step. In other words, the spatial analysis unit 63 may have at least one of the functions of the environmental calculation unit 64 and some of the functions of the determination unit 65.

[0103] (summary) As described above, the setting method according to the first embodiment includes a spatial analysis step, an environmental calculation step, a determination step, and a modification step. In the spatial analysis step, a spatial analysis is performed based on the driving conditions of the air conditioning equipment (19) installed in the indoor space (10) and information on the installation location of the air conditioning equipment (19). In the environmental calculation step, the average temperature and average wind speed of a specific space (15) in the indoor space (10) are determined based on the results of the spatial analysis. In the determination step, a decision is made based on the results of the spatial analysis whether or not to change the driving conditions of the air conditioning equipment (19). In the modification step, if it is determined in the determination step that the driving conditions should be changed, the driving conditions of the air conditioning equipment (19) are changed based on a predetermined relationship between the target temperature and target wind speed, which are set in advance so that the specific space (15) becomes a desired PMV space, and the average temperature and average wind speed obtained in the environmental calculation step. In the setting method, after changing the driving conditions of the air conditioning equipment (19) in the modification step, the spatial analysis step and the determination step are performed again based on the modified driving conditions.

[0104] According to this embodiment, for example, if the specific space (15) is not the desired PMV space, the driving conditions of the air conditioning equipment (19) are changed based on a predetermined relationship between the target temperature and target wind speed and the average temperature and average wind speed obtained in the environmental calculation step. Therefore, according to the setting method, the driving conditions of the air conditioning equipment (19) can be set so that the specific space (15) becomes the desired PMV space.

[0105] In the setting method relating to the second embodiment, in the determination step, based on the results of spatial analysis, the PMV value, which is a quantitative representation of the degree to which a person present in a specific space (15) feels the temperature, and the PMV spatial volume ratio of the specific space (15) are determined. In the determination step, a decision is made as to whether or not to change the driving conditions of the air conditioning equipment (19) based on the determined PMV spatial volume ratio of the specific space (15).

[0106] According to this embodiment, in order to determine whether or not to change the driving conditions of the air conditioning equipment (19) based on the PMV spatial volume ratio of the specific space (15), the driving conditions of the air conditioning equipment (19) can be changed, for example, if the specific space (15) is not the desired PMV space.

[0107] In the setting method relating to the third embodiment, in the determination step, the PMV value and PMV spatial volume ratio of the specific space (15) are determined based on the results of the spatial analysis and the predetermined amount of clothing, activity level, and humidity.

[0108] According to this embodiment, since the PMV of a specific space (15) is determined using pre-set clothing amount, activity level, and humidity (fixed value information), the PMV value and PMV spatial volume ratio of the specific space (15) can be easily determined.

[0109] In the setting method relating to the fourth embodiment, in the second or third embodiment, in the determination step, the PMV value and PMV spatial volume fraction of the specific space (15) are determined by assuming that the humidity of the specific space (15) is uniform and the radiant temperature of the specific space (15) is the same as the temperature of the specific space (15).

[0110] According to this embodiment, by simplifying some of the multiple parameters used to determine the PMV value of the specific space (15), it becomes easier to determine the PMV value and the PMV space volume ratio of the specific space (15).

[0111] In the setting method relating to the fifth embodiment, in any of the first to fourth embodiments, the driving conditions for the air conditioning equipment (19) include at least one of the set temperature and the set air velocity.

[0112] According to this embodiment, for example, by changing at least one of the set temperature and set air velocity of the air conditioning equipment (19) in the modification step, the specific space (15) can be made to become the desired PMV space.

[0113] In the setting method relating to the sixth embodiment, in any of the first to fifth embodiments, the specific space (15) is a space that is 0.1m or more above the floor and 1.7m or less above the floor, and is at least 1m away from the wall surface (11) provided in the interior space (10).

[0114] According to this embodiment, the specific space (15) is the space within the indoor space (10) where there is a high probability that people are actually present. In other words, according to this embodiment, the space within the indoor space (10) where there is a high probability that people are actually present can be designated as the desired PMV space, thereby providing a comfortable space for people using the indoor space (10).

[0115] The setting method according to the seventh embodiment further includes an initial condition setting step in any of the first to sixth embodiments. In the initial condition setting step, initial conditions for the operation conditions of the air conditioning equipment (19) are set based on the heat load calculation of the indoor space (10). In the spatial analysis step, a spatial analysis is performed based on the initial conditions of the air conditioning equipment (19) and information on the installation location of the air conditioning equipment (19).

[0116] According to this embodiment, the initial conditions for the operation of the air conditioning equipment (19) are set based on the heat load calculation of the indoor space (10), making it easier to set appropriate initial conditions.

[0117] In the setting method relating to the eighth aspect, the heat load calculation is performed for both cooling and heating in the seventh aspect.

[0118] According to this embodiment, regardless of whether the air conditioning equipment (19) is operating in cooling mode or heating mode, the driving conditions of the air conditioning equipment (19) can be set so that the specific space (15) becomes the desired PMV space.

[0119] In the setting method relating to the ninth embodiment, in any of the first to eighth embodiments, if the change step has already been performed a predetermined number of times or more, it is determined in the determination step that the driving conditions of the air conditioning equipment (19) will not be changed.

[0120] According to this embodiment, by determining that the driving conditions of the air conditioning equipment (19) should not be changed when the change step has already been performed more than a predetermined number of times, the time required to set the driving conditions of the air conditioning equipment (19) for specific spaces (15) that are difficult to make into a desired PMV space can be reduced.

[0121] The setting method according to the tenth embodiment further comprises a position setting step in any of the first to ninth embodiments. In the position setting step, the installation position of the air conditioning equipment (19) is set based on the position of one or more openings present in the indoor space (10). In the spatial analysis step, spatial analysis is performed based on the driving conditions of the air conditioning equipment (19) and the information on the installation position of the air conditioning equipment (19) set in the position setting step.

[0122] According to this embodiment, the installation position of the air conditioning equipment (19) is determined based on the position of one or more openings, making it easier to install the air conditioning equipment (19) in an appropriate position.

[0123] In the setting method according to the 11th embodiment, in the case where one or more openings include an air supply section (17) and an exhaust section (18) in the 10th embodiment, in the position setting step, the dot product of a first vector (V1) moving from the air supply section (17) to the exhaust section (18) and each of a plurality of second vectors (V2) which are a plurality of vertical vectors corresponding to a plurality of wall surfaces (11) provided in the indoor space (10) is calculated, and the wall surface (11) corresponding to the second vector (V2) with the largest dot product among the plurality of second vectors (V2) is set as the installation position of the air conditioning equipment (19).

[0124] According to this embodiment, the efficiency of cooling or heating can be improved by aligning the direction of the airflow out of the air conditioning equipment (19) with the direction of the airflow entering into one or more openings or the direction of the airflow out of one or more openings.

[0125] In the setting method according to the 12th embodiment, in the 10th embodiment, when one or more openings are an air supply unit (17) and an inlet / outlet (16), in the position setting step, the dot product of a first vector (V1) moving from the air supply unit (17) to the inlet / outlet (16) and each of a plurality of second vectors (V2) which are a plurality of vertical vectors corresponding to a plurality of wall surfaces (11) provided in the indoor space (10) is calculated, and the wall surface (11) corresponding to the second vector (V2) with the largest dot product among the plurality of second vectors (V2) is set as the installation position of the air conditioning equipment (19).

[0126] According to this embodiment, the efficiency of cooling or heating can be improved by aligning the direction of the airflow out of the air conditioning equipment (19) with the direction of the airflow entering into one or more openings or the direction of the airflow out of one or more openings.

[0127] In the setting method relating to the 13th embodiment, in the 10th embodiment, when one or more openings are an exhaust section (18) and an inlet / outlet (16), in the position setting step, the dot product of a first vector (V1) moving from the inlet / outlet (16) to the exhaust section (18) and each of a plurality of second vectors (V2) which are a plurality of vertical vectors corresponding to a plurality of wall surfaces (11) provided in the indoor space (10) is calculated, and the wall surface (11) corresponding to the second vector (V2) with the largest dot product among the plurality of second vectors (V2) is set as the installation position for the air conditioning equipment (19).

[0128] According to this embodiment, the efficiency of cooling or heating can be improved by aligning the direction of the airflow out of the air conditioning equipment (19) with the direction of the airflow entering into one or more openings or the direction of the airflow out of one or more openings.

[0129] In the setting method relating to the 14th embodiment, in the 10th embodiment, when one or more openings are entrances (16), in the position setting step, the dot product of a first vector (V1) extending from the entrance (16) to the outside and each of a plurality of second vectors (V2) which are a plurality of vertical vectors corresponding to a plurality of wall surfaces (11) provided in the indoor space (10) is calculated, and the wall surface (11) corresponding to the second vector (V2) with the largest dot product among the plurality of second vectors (V2) is set as the installation position for the air conditioning equipment (19).

[0130] According to this embodiment, the efficiency of cooling or heating can be improved by aligning the direction of the airflow out of the air conditioning equipment (19) with the direction of the airflow entering into one or more openings or the direction of the airflow out of one or more openings.

[0131] Configurations other than those in the first embodiment are not essential to the setup method and can be omitted as appropriate.

[0132] The program relating to the 15th aspect is a program that causes one or more processors to execute a setting method relating to any of the first to 14 aspects.

[0133] According to this embodiment, for example, if the specific space (15) is not the desired PMV space, the driving conditions of the air conditioning equipment (19) are changed based on a predetermined relationship between the target temperature and target wind speed and the average temperature and average wind speed obtained in the environmental calculation step. Therefore, according to the setting method, the driving conditions of the air conditioning equipment (19) can be set so that the specific space (15) becomes the desired PMV space.

[0134] The setting system (1) according to the 16th embodiment comprises a spatial analysis unit (63), an environmental calculation unit (64), a determination unit (65), and a modification unit (66). The spatial analysis unit (63) performs spatial analysis based on the driving conditions of the air conditioning equipment (19) installed in the indoor space (10) and information on the installation location of the air conditioning equipment (19).
