Description

The present disclosure relates to an air conditioning design specification proposal method, an air conditioning design specification proposal system, and an air conditioning design specification proposal program.

Conventionally, in a residential air conditioning system, one air conditioner is provided, the heat load of each room (each zone) is measured, and hot air or hot air sent from the air conditioner is sent according to the order of the magnitude of the heat load. A system for controlling the opening degree of a damper installed in each branch of a duct that guides cold air to each room is known (see, for example, Patent Document 1). Further, since the maximum air-conditioning load in each zone of the house and the air-conditioning load for each hour cannot be grasped, an air-conditioning system having a margin in the maximum air-conditioning capacity is known.

However, in the air conditioning system described in Patent Document 1, control for adjusting the opening degree of the damper provided in each room is required, the system tends to be complicated, and the cost required for the equipment tends to be high. Further, in an air-conditioning system having a margin in the maximum air-conditioning capacity, the cost required for the equipment tends to be high because the air-conditioning capacity is increased. By the way, in the air-conditioning system of one dwelling unit of a house, the air-conditioning load of each zone is, for example, temperature / humidity conditions due to season / time zone, housing specification conditions, usage of each zone, orientation conditions of each zone, thermal conditions and housing. Performance etc. will affect. Therefore, in consideration of these influences, it is preferable to set the air conditioning design specifications of the house to the air conditioning design specifications that can reduce the air conditioning load in each zone.

Therefore, it is required to effectively propose the air-conditioning design specifications of the air-conditioning system of one dwelling unit of a house without making the air-conditioning system a complicated system.

The air conditioning load in each zone is calculated based on at least one of the temperature / humidity conditions, housing specification conditions, usage of each zone, orientation conditions of each zone, thermal conditions, and housing performance due to the season / time zone. .. The details of the air conditioning load will be described later. These air-conditioning loads can be obtained by, for example, various calculation formulas, various weightings, various tables, etc. by the user inputting each condition from the input unit 551 of the input / output device 55. The user can calculate the value of the air conditioning load by inputting the air conditioning load condition to the input unit 551 of the input / output device 55.

The air conditioning capacity in each zone is calculated based on the number of air supply ports arranged in each zone and the air supply capacity of the air supply port per location. The details of the air conditioning capacity will be described later.

The proposal item output unit 524 outputs the proposal items of the air conditioning design specifications based on the determination results determined by the first determination unit 522 and the second determination unit 523. Specifically, when the proposal matter output unit 524 determines that the number of air supply ports is larger than the number of air supply ports calculated from the floor area based on the maximum load of each zone by the first determination unit 522, or When the first determination unit 522 determines that the total number of air supply ports is larger than the predetermined number of air supply ports, the proposal items of the air conditioning design specifications are output. Proposal matter When the second determination unit 523 determines that the air conditioning load factor of each zone is larger than the predetermined air conditioning load factor, the second determination unit 523 determines that the time of each zone of the air conditioning load factor is larger than the predetermined air conditioning load factor. When it is determined that the variation for each band is not within the predetermined range, or when the second determination unit 523 determines that the variation between the zones of the air conditioning load factor is not within the predetermined range, the proposal items of the air conditioning design specifications are set.

Changes in the solar shading specifications include, for example, the installation of eaves and shades. Changes in the opening specifications include, for example, changing the dimensions of the opening. Changes in the floor plan of the zones and the partition specifications of the adjacent zones include, for example, widening the zone or narrowing the zone by providing a partition in the adjacent zone or removing the partition.

For example, when it is connected vertically due to a stairwell or the like, it can be determined as an integrated space.

In this embodiment, each verification is performed by finding the maximum air conditioning load having the largest air conditioning load from the input contents. As the maximum air-conditioning load in the heating period, for example, the heating air-conditioning load at 6 o'clock in the early morning of the heating period is obtained, and as the maximum air-conditioning load in the cooling period, for example, the cooling air-conditioning at 9:00 am, 13:00 noon, and 16:00 in the cooling period. Find the load. In the heating period, heating is turned on at 6 o'clock in the early morning when the room temperature is low, so it is assumed that 6 o'clock in the early morning is the time when the air conditioning load is the highest. In addition, in the cooling period, in order to make the cooling effective in any time zone of morning, noon, and evening, it is assumed that the time zone where the air conditioning load is the highest is 6:00 am, 13:00 noon, and 16:00 pm.

(B) Items related to air conditioning capacity include the number of air supply ports and the air supply capacity of each air supply port. This is because the air conditioning capacity in each zone is calculated based on the number of air supply ports arranged in each zone and the air supply capacity of the air supply ports per location. Specifically, regarding the number of air supply ports, if the number of air supply ports is large, the air supply capacity is high, and if the number of air supply ports is small, the air supply capacity is low. Regarding the air supply capacity of the air supply port per location, if the size of the opening diameter of the air supply port is large, the air supply capacity is high, and if the size of the opening diameter is small, the air supply capacity is low. In the present embodiment, for example, a duct having a diameter of 75 mm or 100 mm is prepared and installed at an appropriate place. An air supply port arranged in each zone is provided at the end of the duct, and in the present embodiment, the opening diameter of the air supply port and the diameter of the duct are the same.

It is preferable that the number of air supply ports and the air supply capacity are set according to the floor area of each zone and the air conditioning load. However, it may be difficult to install the duct when the space for installing the duct is limited or the cost of installing the duct is high. When the house is newly built, the air-conditioning load factor of each zone can be set to a preferable value by designing the house in advance considering the number of air supply ports as the air-conditioning capacity and the air-conditioning capacity. It is possible to propose proposals for air conditioning design specifications that are relatively small. Further, in the case of a remodeled house, it is often difficult to newly install a duct, so it is possible to propose proposals for air conditioning design specifications based on the current number of air supply ports and air supply capacity.

For example, the first determination unit 522 determines whether or not the number of air supply ports is less than or equal to the number of air supply ports calculated from the floor area based on the maximum load of each zone, and the total number of air supply ports is less than or equal to the predetermined number of air supply ports. It can be determined whether or not.

When determining whether or not the number of air supply ports is less than or equal to the number of air supply ports calculated from the floor area based on the maximum load of each zone, the first determination unit 522 obtains the maximum heating / cooling load of each zone and processes the load. Calculate the number of air-conditioning air supply ports that can be used, and compare the calculated number of air-conditioning air supply ports with the number of air-conditioning air supply ports calculated from the floor area. If the calculated number of air-conditioning air supply ports is less than or equal to the number of air-conditioning air supply ports calculated from the floor area, the number of ducts is also suppressed to a certain number. Therefore, it is determined that the condition is satisfied. For example, when the first determination unit 522 determines that the conditions are not satisfied, the proposal item output unit 524 can display the proposal items of the air conditioning design specifications on the display unit 552 of the input / output device 55.

Further, when the first determination unit 522 determines whether or not the total number of air supply ports is equal to or less than the predetermined number of air supply ports, the first determination unit 522 determines that the condition is satisfied if the total number of air supply ports is equal to or less than the upper limit number of air supply ports. do. For example, when it is determined by the first determination unit 522 that the conditions are not satisfied, the proposal items of the air conditioning design specifications can be displayed on the display unit 552 of the input / output device 55.

For example, when it is determined by the first determination unit 522 that the number of air supply ports is larger than the number of air supply ports calculated from the floor area in the heating period, or when the total number of air supply ports is determined to be larger than the predetermined number of air supply ports. There are proposals to improve the performance of exterior wall, ceiling / roof insulation, floor / foundation insulation, proposals to improve the thermal transmission rate of the opening of a room with a high heat loss value, and other than the south side. The opening can display the proposal of reducing the size of the opening on the display unit 552 of the input / output device 55.

Further, when it is determined by the first determination unit 522 that the number of air supply ports is larger than the number of air supply ports calculated from the floor area in the cooling period, or when the total number of air supply ports is determined to be larger than the predetermined number of air supply ports. There are proposals to improve the solar shielding performance of openings with high solar heat gains, proposals to reduce the size of openings other than the south surface, and exterior wall, ceiling / roof insulation. The proposal for improving the heat insulating performance of the floor / basic heat insulation can be displayed on the display unit 552 of the input / output device 55.

Using the above conditions of air conditioning load and air conditioning capacity, the air conditioning load factor calculation unit 521 calculates the air conditioning load factor by dividing the air conditioning load by the air conditioning capacity for each zone. The air-conditioning load factor of each zone calculated by the air-conditioning load factor calculation unit 521 is calculated for each zone at 9:00 in the cooling period, 13:00 in the cooling period, 16:00 in the cooling period, and 6:00 in the heating period. , Shown in the graph shown in FIG.

The second determination unit 523 can determine whether or not the air conditioning load factor calculated by the air conditioning load factor calculation unit 521 satisfies a predetermined condition.

Specifically, (i) the second determination unit 523 determines whether or not the air conditioning load factor of each zone calculated by the air conditioning load factor calculation unit 521 is larger than the predetermined air conditioning load factor. (Ii) The second determination unit 523 determines whether or not the variation of the air conditioning load factor calculated by the air conditioning load factor calculation unit for each time zone is within a predetermined range. (Iii) The second determination unit 523 determines whether or not the variation of the air conditioning load factor calculated by the air conditioning load factor calculation unit 521 between the zones is within a predetermined range.

(I) In the case of determining whether or not the air conditioning load factor of each zone calculated by the air conditioning load factor calculation unit 521 by the second determination unit 523 is larger than the predetermined air conditioning load factor, for example, the air conditioning load factor is 100. If it exceeds%, the air conditioning load is larger than the air conditioning capacity, and the air conditioning capacity is insufficient, so that the zone cannot be efficiently cooled or heated. Therefore, for example, assuming that the predetermined air conditioning load factor is 100%, the second determination unit 523 determines whether or not the air conditioning load factor of each zone is larger than the predetermined air conditioning load factor. As a result, when it is determined that the air conditioning load factor of each zone is larger than the predetermined air conditioning load factor, the proposal item output unit 524 transmits the proposal items of the air conditioning design specifications to the display unit 552 of the input / output device 55. It can be displayed.

In the present embodiment, referring to the graph shown in FIG. 4, the air conditioning load factor does not exceed 100% in each zone and each time zone. Therefore, the proposal item output unit 524 does not display the proposal item of the air conditioning design specification on the display unit 552 of the input / output device 55. If there is a zone in which the air conditioning load factor exceeds 100%, the proposal item output unit 524 can display the proposal items of the air conditioning design specifications on the display unit 552 of the input / output device 55. Based on these proposals, the user can improve the matters related to the air conditioning of the house.

(Ii) When determining whether or not the variation of the air conditioning load factor for each zone calculated by the air conditioning load factor calculation unit by the second determination unit 523 is within the predetermined range, the time zones are different. The air conditioning load may increase or decrease due to the infiltration of sunlight. Therefore, the second determination unit 523 determines whether or not the variation of the air conditioning load factor for each time zone in each zone is within a predetermined range. As a result, if it is determined that the variation of the air conditioning load factor calculated by the air conditioning load factor calculation unit 521 for each time zone is not within the predetermined range, the proposal item output unit 524 proposes the air conditioning design specifications. The matter can be displayed on the display unit 552 of the input / output device 55. Based on these proposals, the user can improve the matters related to the air conditioning of the house.

In the present embodiment, referring to the graph shown in FIG. 4, in the LDK / washroom (1st floor, 1st zone 11), the air conditioning load factor at 9 o'clock in the cooling period and the air conditioning load factor at 13:00 in the cooling period. The difference is 3 pt (points) as shown in Table 1. In the skip floor / 2nd floor corridor (2nd floor, 3rd zone 23), the difference between the air conditioning load factor at 9 o'clock in the cooling period and the air conditioning load factor at 16:00 in the cooling period is as shown in Table 1. It is 21.9 pt. In the present embodiment, the range within the predetermined range, which is the determination threshold value, is, for example, within 30 pt, so that the determination criteria are satisfied (determination OK). Therefore, the proposal item output unit 524 does not display the proposal item of the air conditioning design specification on the display unit 552 of the input / output device 55. In the present embodiment, the value within the predetermined range, which is the determination threshold value, is set to 30 pt or less, but the present invention is not limited to this. The predetermined range, which is the determination threshold value, can be obtained from the results of trial tests using houses based on various housing specifications.

As shown in FIG. 4, in the skip floor / second floor corridor (second floor third zone 223), the difference between the air conditioning load factor at 9 o'clock in the cooling period and the air conditioning load factor at 16:00 in the cooling period is 21. It is 9pt. Although it is within the predetermined range of 30 pt, which is the determination threshold, there is room for countermeasures. For example, in the cooling period, measures may be taken to improve the solar radiation shielding performance in the zone where the difference in the air conditioning load factor is the largest. As measures to improve the solar radiation shielding performance, for example, there are measures such as installing eaves, shades, etc., installing eaves on the south side, and changing to glass with a low solar heat acquisition rate other than the south side. The content of the measures is not limited to this, and is appropriately selected depending on the housing situation and the like.

(Iii) When the second determination unit 523 determines whether or not the variation of the air conditioning load factor for each zone calculated by the air conditioning load factor calculation unit 521 is within a predetermined range, the same is applied for each zone. If there is a variation in the air-conditioning load factor depending on the time of day, the air-conditioning may become less effective or more effective. Therefore, the second determination unit 523 determines whether or not the variation for each time zone in each zone is within a predetermined range.

As a result, if it is determined that the variation of the air conditioning load factor calculated by the air conditioning load factor calculation unit 521 for each time zone is not within the predetermined range, the proposal item output unit 524 proposes the air conditioning design specifications. The matter can be displayed on the display unit 552 of the input / output device 55. Based on these proposals, the user can improve the matters related to the air conditioning of the house.

In the present embodiment, referring to the graph shown in FIG. 4, as shown in Table 2, the maximum difference in the air conditioning load factor is 17 pt at 9 o'clock in the cooling period, and air conditioning at 13:00 in the cooling period. The maximum difference in load factor is 22 pt, and the maximum difference in air conditioning load factor is 33 pt at 16:00 in the cooling period. At 9 o'clock in the heating period, the maximum difference in the air conditioning load factor is 28p.

Since the predetermined range, which is the determination threshold value, is within 45 pt, for example, the determination criteria are satisfied at 9:00, 13:00, 16:00 in the cooling period and 6:00 in the heating period (determination OK). Therefore, the proposal item output unit 524 does not display the proposal item of the air conditioning design specification on the display unit 552 of the input / output device 55. In the present embodiment, the predetermined range, which is the determination threshold value, is set to 45 pt, but the present invention is not limited to this. The predetermined range, which is the determination threshold value, can be obtained from the results of trial tests using houses based on various housing specifications.

Here, at 16:00 in the cooling period, the maximum difference in the air conditioning load factor is 33 pt. Since the range within the predetermined range, which is the determination threshold value, is, for example, 45 pt or less, the determination criteria are satisfied. However, at 16:00 in the cooling period, the variation is the largest in each time zone, so a solar shading device (shade) is placed in the opening on the south side of the 1st floor 1st zone 11 on the 1st floor 10 and the heat insulation is strengthened. You may take measures such as doing so.

Next, an example of the operation of the air conditioning design specification proposal system 50 will be described with reference to the flowchart shown in FIG. First, as a preliminary preparation, the house 1 is divided into each zone.

As shown in FIG. 5, each input item is input in step S1. As input items, for example, as shown in the input contents of FIG. 3, (1) site items, (2) air conditioning / ventilation items, (3) whole house items, (4) zone items, etc. Can be mentioned.

In step S2, the control unit 52 calculates the air conditioning load for each zone. The air conditioning load in each zone is calculated based on at least one of the temperature / humidity conditions, housing specification conditions, usage of each zone, orientation conditions of each zone, thermal conditions, and housing performance due to the season / time zone. ..

In step S3, the user calculates the number of air supply ports to be installed in each zone. Look at the calculated number of air supply ports and change manually only when changing the number of air supply ports. The air conditioning capacity in each zone is calculated based on the number of air supply ports arranged in each zone and the air supply capacity of the air supply port per location. This makes it possible to calculate the air conditioning capacity in each zone. The number of air supply ports installed in each zone may be determined and obtained from the first determination unit 522.

In step S4, the air conditioning load factor calculation unit 521 calculates the air conditioning load factor for each zone by dividing the air conditioning load by the air conditioning capacity. As a result, as shown in FIG. 4, the air conditioning load factor for each zone can be calculated.

In step S5, the second determination unit 523 determines whether or not the air conditioning load factor of any of the zones is 100% or less. When the second determination unit 523 determines that the air conditioning load factor of each zone is 100% or less (determination OK), the process proceeds to step S7. When the second determination unit 523 determines that the air conditioning load factor of each zone is not 100% or less (determination NG), the process proceeds to step S6.

In step S6, since it was determined in step S5 that the air conditioning load factor of each zone was not 100% or less, the proposal item output unit 524 causes the display unit 552 of the input / output device 55 to display the proposal items of the air conditioning design specifications. By applying the proposals of the air conditioning design specifications to the zone where the air conditioning load factor exceeds 100%, the user can improve the matters related to the air conditioning of the house. After displaying the proposal in step S6, the process returns to step S5.

In step S7, the second determination unit 523 determines whether or not the variation in the air conditioning load factor for each time between the zones is within a predetermined range. When the second determination unit 523 determines that the variation in the air conditioning load factor for each time between the zones is within a predetermined range (determination OK), the process proceeds to step S9. When the second determination unit 523 determines that the variation in the air conditioning load factor for each time between the zones is not within the predetermined range (determination NG), the process proceeds to step S8.

In step S8, since it was determined in step S7 that the variation in the air conditioning load factor for each time between the zones was not within the predetermined range, the proposal item output unit 524 transfers the proposal items of the air conditioning design specifications to the input / output device 55. It is displayed on the display unit 552. By applying the proposals for air-conditioning design specifications to zones with large variations in each time zone, users can improve matters related to air-conditioning in houses. After displaying the proposal in step S8, the process returns to step S7.

In step S9, the second determination unit 523 determines whether or not the variation in the air conditioning load factor between the zones is within a predetermined range. When the second determination unit 523 determines that the variation in the air conditioning load factor between the zones is within a predetermined range (determination OK), the process ends. When the second determination unit 523 determines that the variation in the air conditioning load factor between the zones is not within the predetermined range (determination NG), the process proceeds to step S10.

In step S10, since it was determined in step S9 that the variation in the air conditioning load factor between the zones was not within the predetermined range, the proposal item output unit 524 displays the proposal items of the air conditioning design specifications on the display unit 552 of the input / output device 55. To display. By applying the proposals of the air-conditioning design specifications to the zones where the variation of the air-conditioning load factor for each time zone is large, the user can improve the matters related to the air-conditioning of the house. After displaying the proposal in step S10, the process returns to step S9.

In the control of this flowchart, the second determination unit 523 controls whether or not the air conditioning load factor of any of the zones executed in step S5 is 100% or less, and is executed in step S7. Control to determine whether or not the variation of the air conditioning load factor between zones for each time is within the predetermined range, and whether or not the variation of the air conditioning load factor between the zones executed in step S9 is within the predetermined range. The control for determining whether or not the control is executed in this order, but the order of the three determination controls is not limited to this. Further, the second determination unit 523 may execute one or two determination controls without executing all three determination controls.

The third zone 73 on the second floor is composed of, for example, a study. In this embodiment, the second floor third zone 73 is the space on the south side of the second floor 70. The second floor fourth zone 74 is composed of the second floor hall. The 4th zone 74 on the 2nd floor is located on the south side of the 1st zone 71 on the 2nd floor and on the north side of the 3rd zone 73 on the 2nd floor. The 4th zone 74 on the 2nd floor and the 1st zone 61 on the 1st floor are connected by a stairwell.

As shown in FIG. 6, an opening in which a window is arranged is provided at an appropriate position in each zone 61, 62, 63, 71, 72, 73, 74 of the above housing 1A, and an opening specification is set. , Predetermined heat insulation specifications are set.

Specifically, as shown in FIG. 6, on the 1st floor 60, the 1st floor 1st zone 61 and the 1st floor 2nd zone 62 are separated by the door 614 by being closed by the door 614. The 1st floor 1st zone 61 and the 1st floor 2nd zone 62 are configured as separate zones. Further, a plurality of openings are provided in the first zone 61 on the first floor, and windows are housed in the openings.

Of the two openings 611c and 611d on the south side of the LDK 611 in the first zone 61 on the first floor, the screen 82 having heat shielding performance is installed in the opening 611d on the east side.

On the second floor 70, a screen 82 having heat shielding performance is installed in the opening 711 on the north side and the opening 712 on the east side of the first zone 71 on the second floor. A screen 82 having heat shielding performance is installed in the opening 721 on the south side and the opening 722 on the west side of the second zone 72 on the second floor.

The air conditioning system 30A includes one air conditioner (not shown), ducts piped toward each zone 61, 62, 63, 71, 72, 73, 74 (not shown), and each zone 61, It has an air supply port 33 arranged at 62, 63, 71, 72, 73, 74.

Three air supply ports 33 are arranged in the LDK 611 (Living Dining Kitchen) of the first zone 61 on the first floor. 1st floor 2nd zone 62, 1st floor 3rd zone 63, 2nd floor 1st zone 71, 2nd floor 2nd zone 72, 2nd floor 3rd zone 73 and 2nd floor 4th zone 74, respectively, one air supply The mouth 33 is arranged. In the house 1, one air conditioner (not shown) is operated by the air conditioning system 30 with a predetermined air conditioning capacity.

In the air-conditioning design specification proposal system 50 (see FIG. 2) of the embodiment, the air-conditioning load factor calculation unit 521 calculates the air-conditioning load factor obtained by dividing the air-conditioning load by the air-conditioning capacity for each zone. The air conditioning load is calculated, for example, by inputting the input contents shown in FIG. 3 into the input unit 551 of the input / output device 55. The air conditioning capacity is calculated, for example, by inputting the number of air supply ports and the opening diameter into the input unit 551 of the input / output device 55. The air conditioning load factor calculation unit 521 calculates the air conditioning load factor for each zone by dividing the air conditioning load by the air conditioning capacity based on the calculated air conditioning load and air conditioning capacity. As a result, as shown in the graph shown in FIG. 7, the air conditioning load factor for each zone can be calculated before the countermeasure is taken.

In the air-conditioning load factor of each zone shown in FIG. 7, as zones in which the air-conditioning load factor exceeds 100%, there are 1st floor 1st zone 61 and 2nd floor 4th zone 74 connected by a stairwell and integrated. Further, as shown in Table 3 below, the zones determined by the second determination unit 523 for each time zone are not within a predetermined range (for example, the determination threshold value is within 30 pt), and are connected and integrated. There are 1st floor 1st zone 61 and 2nd floor 4th zone 74 (maximum difference in air conditioning load factor is 36pt).

Further, as shown in Table 4 below, as a zone in which the variation between the zones determined by the second determination unit 523 is not within a predetermined range (for example, the determination threshold value is within 45 pt), cooling at 9 o'clock (76 pt), cooling 13 There are hours (65 pt), cooling 16:00 (59 pt), and heating 6 o'clock (75 pt). In this embodiment, when the second determination unit 523 determines whether or not the variation between the zones is within a predetermined range, the second zone 62 (utility) on the first floor is not a living room in the house 1A. Therefore, the variation between the zones is determined without including the second zone 62 (utility) on the first floor.

Since there is a zone in which the air conditioning load factor does not satisfy a predetermined condition, the proposal items of the air conditioning design specifications are displayed on the display unit 552 of the input / output device 55. In the present embodiment, for example, in the display unit 552 of the input / output device 55, as a proposal of the air conditioning design specifications, as shown in FIG. 8, the first floor first zone 61 and the first floor second zone of the first floor 60 In addition to connecting the 1st floor 1st zone 61 and the 2nd floor 4th zone 74 with a stairwell, the door 614 is opened to connect the 1st floor 2nd zone 62 to the 1st floor first floor. The 1st zone 61, the 4th zone 74 on the 2nd floor, and the 2nd zone 62 on the 1st floor can be changed into one space, and the honeycomb screen provided in the opening 611c on the south side of the 1st floor 1st zone 61 on the 1st floor 60. The thickness of the rising portion of the basic heat insulation of the wall portion 84 on the east side of the 1st floor 1st zone 61 of the 1st floor 60 is changed from 50 mm to 100 mm by changing the 81A to one having heat insulation performance and high heat insulation performance. It was displayed to change to. Based on these proposals, the user can improve the matters related to the air conditioning of the house.

After the measures changed in this way, the air conditioning load factor calculation unit 521 again calculates the air conditioning load factor obtained by dividing the air conditioning load by the air conditioning capacity for each zone. After the measures are taken, the air conditioning load factor for each zone can be calculated as shown in the graph shown in FIG.

In the air conditioning load factor of each zone at each time shown in FIG. 9, there is no zone in which the air conditioning load factor exceeds 100%. Further, as shown in Table 5 below, there are no zones in which the time-dependent variation of the air conditioning load factor between each zone is not within a predetermined range (for example, the determination threshold value is within 30 pt).

Further, as shown in Table 6 below, after the improvement, the zones in which the variation between the zones is within the predetermined range are cooling 9 o'clock (45 pt) and cooling 16 o'clock (45 pt), and the variation between the zones is Zones that are not within the predetermined range include cooling at 13:00 (47 pt) and heating at 6:00 (58 pt). Therefore, the number of zones in which the variation in the air conditioning load factor between the zones is not within the predetermined range (for example, within the determination threshold value of 45 pt) is smaller than that before the improvement, and the variation between the zones is reduced.
