Description

  The present invention relates to an air conditioning system, an air conditioning control device, and an air conditioning control method, and in particular, an air conditioning system and air conditioning control for air conditioning for an indoor space having a spatially continuous interior zone and a perimeter zone. The present invention relates to an apparatus and an air conditioning control method.

  In an air conditioning system installed in a building or the like, unlike a pair-type air conditioner used in a home, an air conditioner in which a plurality of indoor units are deployed in one target space such as an office is provided. Often used. These indoor units are used as a common air conditioning environment providing means, operate in cooperation with a central large air conditioner, and are collectively controlled by an air conditioning system called a central air conditioning system. By adopting this central air-conditioning system, it is possible to provide a substantially uniform air-conditioning environment for a target space with a relatively uniform load configuration.

  However, when the space to be air-conditioned is a building or the like, areas with different load forms such as an interior zone and a perimeter zone may be included in the target. In other words, in the interior zone where OA equipment is located, the fluctuation of the thermal load due to air conditioning tends to be relatively small because it is less susceptible to outdoor weather conditions throughout the year, whereas in the perimeter zone, Due to the influence of radiant heat, the fluctuation of heat load tends to be relatively large depending on the season and time. For this reason, in the interior zone, substantially uniform cooling is performed with respect to heat generated from the OA equipment or the like, and in the perimeter zone, air conditioning is performed in which air conditioning is adjusted according to the radiant heat from the windows.

  When areas with different load forms are included in the air conditioning target, an air conditioning system that employs a central air conditioning system may be used in combination with another air conditioning system. For example, with the recent trend toward intelligent building functions, multiple grouped indoor units are connected to outdoor units to meet the demands for comfort in the office environment, enabling individual operation control for each group. A multi-type air conditioning system and a central air conditioning system air conditioning system may be used in combination. In the combined use of such systems, the central air conditioning system air conditioning system is adopted as the interior system, the multi-type air conditioning system is adopted as the perimeter system, and the air conditioning system using these in combination makes it possible to Even when air conditioning is performed on a space including different areas, comprehensive air conditioning management corresponding to those partial load modes is possible.

  However, when air-conditioning is performed on areas with different air-conditioning loads as described above, for example, in the winter season, the perimeter zone requires heating against radiant heat from the window (cold air in the winter season, etc.), and in the interior zone, OA equipment is used. In some cases, it is necessary to cool the heat generated from the heat. Normally, the interior zone and the perimeter zone are spatially continuous. Therefore, when the air conditioning control mode varies depending on the area, the conditioned air for cooling the interior zone and the harmony for heating the perimeter zone are used. Mix with air. In this way, when a reverse load occurs in the conditioned air, each air conditioning unit for the interior zone and the perimeter zone needs more energy to adjust to the set temperature. Will occur.

On the other hand, as shown in the following Patent Document 1 and Patent Document 2, for example, by reducing the heating set temperature of the perimeter zone, the difference in the supply air temperature between the interior zone and the perimeter zone is reduced, A system designed to reduce mixing loss has been devised. Also, the cooling air of the perimeter zone is taken into the air conditioning return side of the interior zone to increase the cooling efficiency of the interior zone, and the air warmed in the interior zone is taken into the air conditioning return side of the perimeter zone to heat the perimeter zone. A system has been devised to reduce the mixing loss by increasing the efficiency of the system.

  On the other hand, in the air conditioning system of the first aspect, the preparation device prepares the first target air used as the return air of the first air conditioner, and the first air and the second area are at least the air in the first area. It is possible to adjust the ratio of the first air and the second air by combining the second air, which is the second air. For this reason, even if the air conditioning load is different between the first area and the second area, it can be combined while adjusting the ratio of the air in both spaces, and the first air conditioner suitable for the return air of the first air conditioner One target air can be prepared.

Adjust.

  Here, the preparation device adjusts the ratio of the first air and the second air so that the temperature of the first target air becomes equal to the temperature of the first conditioned air. For this reason, heat exchange in the first air conditioner is unnecessary, and air conditioning in the first area by the air blowing operation is possible. For this reason, an air conditioning load can be eliminated and more effective energy saving can be achieved.

  The air conditioning system which concerns on the 6th aspect relevant to this invention is an air conditioning system in any one of a 2nd aspect to a 5th aspect, Comprising: The 2nd air conditioner is 2nd which can detect the temperature of 2nd air. It has a temperature detector. When the temperature detected by the first temperature detection unit is higher than the set temperature of the second area and the temperature detected by the second temperature detection unit is lower than the set temperature of the first area, the first air conditioner Stops the first air conditioning function and performs the blowing operation, or the second air conditioner stops the second air conditioning function and performs the blowing operation, and performs at least one of the operations. Here, the set temperature in the first area and the set temperature in the second area may be the same temperature or different. Moreover, it is good also considering both a 1st air conditioner and a 2nd air conditioner as ventilation operation.

  Here, the temperature detected by the first temperature detector is higher than the set temperature of the second area, and at least one of the temperature detected by the second temperature detector and the temperature of the outside air is set in the first area. When it is lower than the temperature, at least one of the first air conditioner and the second air conditioner is blown. For this reason, in the situation where the air-conditioning function of any of the air-conditioning apparatuses is not required to operate, the air-blowing operation can be performed while actively stopping the air-conditioning function. For this reason, the energy required to operate the air conditioning function can be positively eliminated, and further energy saving can be achieved. Here, as a situation where the air conditioning function of the first air conditioner becomes unnecessary, a situation where the temperature detected by the second temperature detection unit is lower than the set temperature of the first area can be considered.

  Here, when the temperature of the first target air prepared by the preparation device is equal to or lower than the set temperature of the first area, the first air conditioning function is stopped and the first target air is used as the first conditioned air in the first area. On the other hand, a blowing operation for supplying air is performed. Therefore, the first air conditioner can prevent the temperature of the first area from rising excessively by blowing the first target air thus prepared to the first area. It is possible to make it difficult to impair comfort. Thereby, the comfort of the first area can be maintained without losing the air conditioning load in the first air conditioner.

  For example, when the temperature detected by the first temperature detection unit is less than the set temperature of the second area, the second air conditioner operates the second air conditioning function and uses the first air as return air. By performing the heating operation in which the second conditioned air is prepared and supplied to the second area, the temperature of the second area can be prevented from dropping too much, and the comfort of the second area is also impaired. It can be difficult.

A blowing operation for supplying air to the two areas is performed. That is, when the temperature of the first area is higher than the set temperature of the second area, the first air containing a larger amount of heat can be supplied to the second area. Thereby, it becomes possible to relieve the state where the temperature of the second air is lower than the set temperature of the second area, and it is possible to make it difficult to impair the comfort of the second area. Thereby, the comfort of the second area can be prevented from being impaired while eliminating the air conditioning load in the second air conditioner.

  Further, for example, when the temperature detected by the first temperature detection unit is equal to or higher than the set temperature of the second area, the first air conditioner operates the first air conditioning function to perform the cooling operation of the first area. Thus, it is possible to prevent the temperature of the first area from rising excessively and to reduce the comfort of the first area. Thereby, it is possible to prevent the comfort of the first area from being impaired.

  Here, even when the air-conditioning target area includes areas with different air-conditioning loads in the interior zone and the perimeter zone, the mixing loss can be effectively reduced.

  An air conditioning system according to a twelfth aspect related to the present invention is an air conditioning system for performing air conditioning for a space having a first area and a second area spatially continuous with the first area. And the 3rd air conditioner and the 2nd air conditioner are provided. The third air conditioner can supply the third conditioned air to the first area.

For example, a damper or the like for taking in a predetermined amount of the first air and an amount corresponding to the amount of the first air 2 A case where a damper or the like for taking in air is separately provided and the ratio is adjusted is also included.

  In the conventional air conditioning system, when a space having areas with different air conditioning loads is air-conditioned by two air conditioners, reduction of mixing loss is attempted by mutually switching the return air system. However, in the conventional air conditioning system, a part of the air-conditioning target area may affect other air-conditioning target areas, and depending on the part of the state, the air-conditioning load on the other air-conditioning target areas may be reduced. There is a risk that it may not be sufficient.

The first air that is and the second air that is the air in the second area can be combined to adjust the ratio of the first air and the second air. For this reason, even if the air-conditioning load is different between the first area and the second area, they can be combined while adjusting the ratio of the air in both spaces. 3 target air can be prepared. For this reason, in the preparation of the third target air by the preparation unit, by adjusting the combination ratio, the third air conditioner can be brought close to the target conditioned air state provided to the first area. The air conditioning load of the air conditioner can be reduced. For this reason, even if it is a situation where the environment of a 1st area and a 2nd area differs, it becomes possible to reduce a mixing loss effectively.

However, in the air conditioning control by the conventional air conditioning control device, a part of the air conditioning target area may affect another air conditioning target area, and depending on the part of the state, the air conditioning load on the other air conditioning target area may be affected. There is a possibility that the reduction of the amount cannot be made sufficient.

  On the other hand, in the air conditioning control device of the thirteenth aspect, in the control of the first target air used as the return air of the first air conditioning device, the control unit is based on the temperature data acquired by the first temperature acquisition unit. The ratio of the first air and the second air can be controlled by combining at least the first air that is the air in the first area and the second air that is the air in the second area. For this reason, even if the air-conditioning load is different between the first area and the second area, they can be combined while controlling the ratio of the air in both spaces. One target air can be prepared.

  In the conventional air-conditioning control method, when a space having areas with different air-conditioning loads is air-conditioned by two air-conditioning devices, the mixing loss is reduced by a method of switching the return air system to each other. However, in the air conditioning control by the conventional air conditioning control method, part of the air conditioning target area may affect other air conditioning target areas, and depending on the part of the state, the air conditioning load on the other air conditioning target area may be affected.

Specifically, the interior return air RA1 is passed through the duct 1 and the perimeter return air RA2 is passed through the duct 8 and the duct 2, whereby the air is mixed into the return air mixed air RA3. The temperature of the return air mixed air RA3 is adjusted by controlling the mixing ratio of the mixing ratio adjusting damper 73, controlling the outside air introduction amount of the outside air introducing damper 77, and the like. Here, the mixing ratio adjustment damper 73 and the outside air introduction damper 77 are the values detected by the interior temperature / humidity sensor 18, the set temperature of the indoor unit 203 or the temperature of the built-in supply air SB, the outside air to be introduced, by the above-described preparation device controller 32. The opening degree of the damper 72 and the damper 76 is controlled based on the temperature of OA and the air supply amount of the air hanger supply air SA in the air hanger 14. Here, the preparation apparatus controller 32 transmits a control signal to the mixing ratio control unit 71 and the outside air introduction amount control unit 75, so that the mixing ratio control unit 71 adjusts the opening degree of the damper 72 and controls the outside air introduction amount control. The part 75 adjusts the opening degree of the damper 76, and the increase / decrease control of the air volume is performed, whereby the temperature of the return air mixed air RA3 is adjusted (see FIG. 2). Thereby, the air han return air RA is prepared and supplied to the return air side of the air han 14.

The amount is adjusted to maintain a constant amount. Here, the amount of outside air OA introduced is a predetermined amount exceeding the minimum outside air compensation amount. The air han return air RA is harmonized by the cooling unit 41, the heating unit 42, the humidification unit 43, and the like of the air han 14, and becomes the air hun air supply SA. The harmonized air han supply air SA is supplied to each VAV unit 16 through the duct 5 by the air supply fan 47, and is supplied to the interior zone IZ by adjusting the air volume in each VAV unit 16. .

  In the building multi-air conditioning system 200, as shown in FIG. 5, the Bilmar return RB, which is the return air from the interior zone IZ, is harmonized by, for example, exchanging heat with the indoor heat exchanger 223 of the indoor unit 203. Qi SB is prepared. The building air supply SB performs air conditioning for the perimeter zone PZ by being supplied to the perimeter zone PZ. Specifically, the Birmal return air RB is taken into the indoor unit 203 through the duct 6 and harmonized by exchanging heat with the indoor heat exchanger 223 to become the Birmal supply air SB. The flow rate of the Bilmar supply air SB is controlled by the blower 243 based on the temperature of the Bilmal supply SB, the value detected by the perimeter temperature / humidity sensor 253, and the like.

<Mixed loss reduction control by cooperative air conditioning system>
As described above, when air conditioning is performed for the interior zone IZ and the perimeter zone PZ of the room 80, the central air conditioning system 100 is caused by the difference in air conditioning load between the interior zone IZ and the perimeter zone PZ. There may be a mixing loss between the conditioned air due to the air and the conditioned air due to the building multi-air conditioning system 200.

  That is, there is heat transfer between the conditioned air prepared by the central air conditioning system 100 for the interior zone IZ and the conditioned air prepared by the building multi-air conditioning system 200 for the perimeter zone PZ. Thus, when the temperature of the interior zone IZ is higher than the set temperature, the temperature of the conditioned air supplied to the perimeter zone PZ on the building multi-air conditioning system 200 side becomes higher, or the temperature of the perimeter zone PZ In a state where the temperature is lower than the set temperature, the situation can be considered where the temperature of the conditioned air supplied to the interior zone IZ on the central air conditioning system 100 side becomes a lower temperature. In the former situation, the output of the central heat source device 110 or the cooling unit 41, which is an air conditioning function in the central air conditioning system 100, is increased, resulting in a mixing loss. In the latter situation, the output of the outdoor heat exchanger (not shown) and the indoor heat exchanger 223, which are air conditioning functions in the building multi-air conditioning system 200, is increased, resulting in a mixing loss.

  Hereinafter, in order to simplify the description, a case where the set temperature of the interior zone IZ and the set temperature of the perimeter zone PZ are set to the same temperature will be described. However, as described above, the set temperatures in both zones are not necessarily the same. There is no need to set it to a value.

  In the present cooperative air conditioning system, in order to cope with the situation in which the mixing loss occurs in this way, as shown in FIG. 4, the mixing loss reduction control that transitions in four states according to the situation of the room 80 is performed. This mixing loss reduction control is mainly applied as air conditioning control in winter when air conditioning is performed on a space having the interior zone IZ and the perimeter zone PZ. However, various types of mixing loss occur as described above. It also applies in the situation. For example, as shown in FIG. 5, an interior in which a perimeter zone PZ that receives a radiant cool air from the window 11 and is subjected to a heating load and an OA device and the like are installed in the winter and a cooling load is applied even in the winter due to heat generation. When air conditioning is performed for the zone IZ, the above-described reverse load is likely to occur, and mixing loss reduction control is performed.

  The four operating states in the mixing loss reduction control are a state in which both the indoor unit 203 and the air hanger 14 are in a heating operation, and a state in which the indoor unit 203 is in a heating operation and the air hung 14 is in a blowing operation (FIG. 4). 2), a state in which the indoor unit 203 is in a blowing operation and the air hanger 14 is in a cooling operation (“cooling self-injection operation” shown in FIG. 4), and both the indoor unit 203 and the air hanger 14 are in cooling. There are four driving states in the driving state. It should be noted that at the start of the mixing loss reduction control, which one of the four operating states is to be controlled is determined based on the set temperature of the interior zone IZ and the temperature of the interior zone IZ at the start. The determination is made by a combination of the operation state and the cooling / heating operation state of the indoor unit 203 based on the set temperature of the perimeter zone PZ and the temperature of the perimeter zone PZ at the start.

  Hereinafter, the state transition of the mixed loss reduction control illustrated in FIG. 4 will be described by taking a winter day as an example.

(Heating operation)
In winter, for example, around 7 o'clock in the morning, in a state where both the interior zone IZ and the perimeter zone PZ are less than the set temperature, as shown in FIG. 6, the indoor unit 203 (“in the figure,“ Both “Bilmar” and the air han 14 of the central air conditioning system 100 perform the heating operation. Specifically, as shown in FIG. 6, the air han 14 has a perimeter return air RA 2 of 15 ° C., an interior return air RA 1 of 22 ° C., and an outside air OA of 5 ° C. by mixing ratio control in the air han return air preparation device 70. The air-han return air RA mixed and adjusted to 20 ° C. is taken in. Then, the air han return air RA, the temperature of which has been adjusted by the mixing ratio control, is heated by the heating unit 42 to prepare the air han supply air SA at 28 ° C. The interior zone IZ is heated by taking care. The adjustment of the mixing ratio in the air han return air preparation device 70 is adjusted to a temperature close to the set temperature value of the air han supply air SA, thereby reducing the air conditioning load. The indoor unit 203 heats the 22 ° C. bilmar return air RB by heating it with the indoor heat exchanger 223 and supplying it to the perimeter zone PZ with the blower 243 as the 36 ° C. bilmar supply SB.

(Heating operation)
Further, at around 10:00 in the morning, the temperature of the interior zone IZ rises due to heat generated from the OA equipment or the like installed in the interior zone IZ, and the interior zone IZ reaches the set temperature. Here, in a state where the perimeter zone PZ has not yet reached the set temperature, as shown in FIG. 7, the air han 14 of the central air conditioning system 100 is in a blowing operation, and the indoor unit 203 of the multi air conditioning system for buildings 200 continues the heating operation. It becomes heating selfish operation. Specifically, as shown in FIG. 7, the air han 14 has a perimeter return air RA2 at 15 ° C., an interior return air RA1 at 26 ° C., and an outside air OA at 5 ° C. by mixing ratio control in the air han return air preparation device 70. The air-han return air RA mixed and adjusted to 22 ° C. is taken in. Then, the air-han return air RA, the temperature of which has been adjusted by the mixing ratio control, is blown as it is as the air-han air supply SA without heat exchange, and is supplied to each area of the interior zone IZ by the air volume adjusting unit 17. The adjustment of the mixing ratio in the air han return air preparation device 70 here is adjusted so that the temperature of the prepared air han return air RA becomes equal to the set temperature of the air han supply air SA, thereby eliminating the air conditioning load on the air han 14. Adjust as follows. Further, the indoor unit 203 heats the 26 ° C. bilmar return air RB by heating it with the indoor heat exchanger 223 and supplying it to the perimeter zone PZ with the blower 243 as the 36 ° C. bilmar supply SB.

(Cooling operation)
Further, at around noon, the amount of heat generated from the OA equipment in the interior zone IZ increases and the temperature further rises, and even if the heating operation is performed, the set temperature of the interior zone IZ is exceeded. Here, in a state where the perimeter zone PZ is still below the set temperature, as shown in FIG. 8, the air hung 14 of the central air conditioning system 100 is in a cooling operation, and the indoor unit 203 of the multi air conditioning system for buildings 200 is in a blowing operation, It becomes air-conditioning selfish operation. Specifically, as shown in FIG. 8, the air han 14 mixes 20 ° C. perimeter return air RA 2, 28 ° C. interior return air RA 1, and 10 ° C. outside air OA by mixing ratio control in the air han return air preparation device 70. The air hand return air RA adjusted to 26 ° C. is taken in. Then, the air han return air RA, the temperature of which has been adjusted by the mixing ratio control, is cooled by the cooling unit 41 and supplied to each area of the interior zone IZ as the air han supply air SA of 22 ° C. by the air volume adjusting unit 17. To cool. The adjustment of the mixing ratio in the air han return air preparation device 70 here is adjusted so that the temperature of the air han return air RA to be prepared approaches the set temperature value of the air han supply air SA and the air conditioning load can be reduced. Further, the indoor unit 203 performs a blowing operation on the return air RB at 28 ° C. without performing heat exchange by the indoor heat exchanger 223, and supplies air to the perimeter zone PZ by the blower 243 as it is as a built-up air supply SB. To do.

(Cooling operation)
In addition, after noon, the amount of heat generated from the OA equipment or the like in the interior zone IZ is remarkably increased, and the set temperature in the interior zone IZ is exceeded even if the cooling operation is performed. Here, in the state where the temperature of the perimeter zone PZ approaches the set temperature and the cooling load becomes large, both the air hanger 14 of the central air conditioning system 100 and the indoor unit 203 of the multi air conditioning system for buildings 200 perform the cooling operation. . The specific air flow is substantially the same as described above, and is omitted.

[Features of the air conditioning system of the present embodiment]
(1)
The conventional air conditioning system aims to reduce the mixing loss caused by the relationship between the conditioned air supplied to the interior zone and the conditioned air supplied to the perimeter zone. However, in the conventional air conditioning system, a part of the air-conditioning target area may affect other air-conditioning target areas, and depending on the part of the state, the air-conditioning load on the other air-conditioning target areas may be reduced. There is a risk of not being able to do enough.

  On the other hand, in the cooperative air conditioning system, the air han return air preparation device 70 mixes the air in the interior zone IZ and the air in the perimeter zone PZ in the preparation of the air han return air RA, and adjusts the ratio of the mixed air. can do. For this reason, even when the air conditioning load is different between the interior zone IZ and the perimeter zone PZ, it can be combined while adjusting the mixing ratio of the air in both spaces, and the air-han return air RA is required in the air conditioning of the interior zone IZ. Can be brought close to the air condition. Thereby, the air-conditioning load of the air hanger 14 can be reduced effectively, and even if the environment of the interior zone IZ and the perimeter zone PZ is different, the mixing loss can be reduced effectively.

  Moreover, in the conventional air conditioning system, when the heating load of the perimeter zone is large, the interior zone may be overcooled. As described above, in the conventional air conditioning system, even if the mixing loss can be reduced to some extent, the comfort of the air-conditioning target area may be impaired.

  On the other hand, in the cooperative air conditioning system, the air han return air preparation device 70 mixes the air in the interior zone IZ and the air in the perimeter zone PZ in the preparation of the air han return air RA, and adjusts the ratio of the mixed air. Thus, the air-han return air RA can be brought close to the target air state for supplying air to the interior zone IZ. Thereby, even if the environment of the interior zone IZ and the perimeter zone PZ is different, effective air conditioning for the interior zone IZ becomes possible.

(2)
In the cooperative air conditioning system, the air supply amount of the VAV unit 16 is adjusted based on the relationship between the temperature of the air-han supply air SA and the value detected by the interior temperature / humidity sensor 18. The mixing ratio is adjusted by the air han return air preparation device 70 so that the temperature of the air han return air RA approaches the temperature of the air han supply air SA. For this reason, it is possible to adjust the flow rate of the air-han supply air SA required to make the interior zone IZ comfortable. Furthermore, the temperature of the air-han return air RA is brought close to the temperature of the air-han supply air SA, thereby reducing the air-conditioning load on the air-conditioning means (the cooling unit 41, the heating unit 42, the humidifying unit 43, and the central heat source device 110). be able to. For this reason, it is possible to simultaneously improve the comfort of the interior zone IZ and the energy saving operation of the central air conditioning system.

  In addition, when the air-han return air preparation device 70 adjusts the mixing ratio so that the temperature of the air-hand return air RA is equal to the temperature of the air-han supply air SA, the air-conditioning means (cooling unit 41, heating unit) of the air-han 14 is used. 42, the humidification unit 43, and the central heat source device 110) can eliminate air-conditioning loads such as heat exchange, and more effective energy saving can be achieved.

(3)
In the cooperative air conditioning system, when the temperature of the air-han return air RA is adjusted to a predetermined temperature by the air-hand return air preparation device 70, the air supply amount by the air volume adjusting unit 17 is adjusted, whereby the air-conditioning of the interior zone IZ is performed. Air conditioning corresponding to load fluctuations can be performed.

(4)
In the cooperative air conditioning system, when the temperature detected by the interior temperature / humidity sensor 18 is less than the set temperature of the perimeter zone PZ, the indoor unit 203 operates the heat exchanger and is harmonized from the Bilmar return air RB. In addition, a heating operation is performed in which the air supply SB is prepared and supplied to the perimeter zone PZ. For this reason, it is possible to make the perimeter zone PZ less likely to lose comfort by the energy saving operation.

  Further, the air han 14 stops the central heat source device 110 and performs a blowing operation for supplying air to the interior zone IZ as the air han supply air SA in harmony with the air han return air RA. That is, the air-hand return air preparation device 70 adjusts the mixing ratio between the interior return air RA1 in a state higher than the set temperature in the interior zone IZ and the perimeter return air RA2 in a state lower than the set temperature in the perimeter zone PZ. Airhan return air RA can be prepared. Therefore, if the temperature detected by the perimeter temperature / humidity sensor 253 is lower than the set temperature of the interior zone IZ, it is possible to prepare the air han return air RA in a state required as the air hun air supply SA. Therefore, the air han 14 can blow the air han supply air SA thus prepared to the interior zone IZ, and can improve the comfort of the interior zone IZ.

(5)
In the above cooperative air conditioning system, when the temperature of the perimeter return air RA2 is lower than the set temperature of the perimeter zone PZ and the temperature of the interior return air RA1 is equal to or higher than the set temperature of the perimeter zone PZ, the indoor unit 203 uses a heat exchanger. The air hunting operation is performed to supply air to the perimeter zone PZ using the interior return air RA1 as the building air supply SB, and the air han 14 operates the central heat source device 110 to supply the air han with the air han return air RA as the return air. A cooling operation is performed in which the air SA is prepared and supplied to the interior zone IZ. That is, when the temperature of the interior return air RA1 is higher than the set temperature of the perimeter zone PZ, the interior return air RA1 containing a larger amount of heat can be supplied to the perimeter zone PZ. Thereby, the state where the temperature of the perimeter return air RA2 is lower than the set temperature of the perimeter zone PZ is relaxed, and the comfort of the perimeter zone PZ can be improved.

[Other Embodiments]
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of invention.

(A)
In the cooperative air conditioning system, the air conditioning control in which the amount of outside air taken in the central air conditioning system 100 is fixed to a predetermined value has been described as an example.

  However, the present invention is not limited to this. For example, when the enthalpy of the outside air OA is smaller than the enthalpy of the air in the interior zone IZ, or when the temperature of the outside air OA is lower than the temperature of the air in the interior zone IZ. In addition, the outside air OA may be actively taken in, and an amount exceeding the predetermined outside air amount may be taken in. In this case, the air han controller 31 determines whether outdoor air cooling is possible or not by comparing values obtained from the sensors. In this case, it is preferable to adjust the amount of outside air to be taken in based on the relationship between the enthalpy of the outside air OA and the enthalpy of the interior zone IZ and the relationship between the temperature of the outside air OA and the temperature of the air in the interior zone IZ. Thereby, it becomes possible to reduce the air conditioning load of the central air conditioning system and save energy.

  In addition, when air conditioning control that actively takes outside air OA is performed in this way, the mixing ratio of the three airs of the interior return air RA1, the perimeter return air RA2, and the outside air OA is adjusted, and the central air conditioning system Air conditioning control may be performed so that the air conditioning load can be reduced or the comfort of the interior zone IZ can be further improved. Thus, by actively taking in the outside air OA, it is possible to improve the freshness of the air in the interior zone IZ, the freshness of the air, and the like.

(B)
In the cooperative air conditioning system, the configuration in which the mixing ratio adjustment damper 73 and the outside air introduction damper 77 provided in the air han return air preparation device 70 of the central air conditioning system 100 are separately provided has been described as an example.

  On the other hand, as shown in FIG. 9, the outside air introduction damper and the mixing ratio adjustment damper are composed of one damper 376, and the interior return air RA1, the perimeter return air RA2, and the outside air OA are simultaneously mixed in one place. You may do it.

(C)
In the cooperative air conditioning system, the case where the air han return air preparation device 70 in the central air conditioning system 100 is provided separately from the air han 14 and controls the mixing ratio adjustment damper 73 and the outside air introduction damper 77 has been described as an example.

  On the other hand, the air han return air preparation device 70 may be configured to be incorporated in the ratio adjustment built-in air han 314, like the mixing ratio adjustment unit 370 shown in FIG. Even in this case, it is possible to achieve the same operations and effects as in the case of the separate configuration.

(D)
In the cooperative air conditioning system, the air han return air preparation device 70 prepares the air han return air RA whose temperature is adjusted.

  On the other hand, the adjustment of the mixing ratio of the interior return air RA1, the perimeter return air RA2, and the outside air OA does not have to be performed at one place. For example, a damper or the like for taking in a predetermined amount of interior return air RA1, a damper or the like for taking in the perimeter return air RA2, and a damper or the like for taking in outside air OA are provided separately, resulting in a confusion ratio. The configuration may be such that is adjusted.

(E)
In the cooperative air conditioning system, the interior zone IZ is mainly air-conditioned by the central air conditioning system 100, the perimeter zone PZ is air-conditioned mainly by the building multi-air conditioning system 200, and both systems are operated under coordinated control by the higher-level equipment management device 12. An example of the system is described.

  On the other hand, the present invention is not limited to the above embodiment. For example, the central air conditioning system 100 is applied to the perimeter zone PZ instead of the building multi air conditioning system 200 shown in the above embodiment. In addition, both the interior zone IZ and the perimeter zone PZ may be air conditioning systems that are cooperatively controlled by the respective central air conditioning systems 100.

  Further, for example, the building multi-air conditioning system 200 is applied to the interior zone IZ instead of the central air conditioning system 100 shown in the above embodiment, and both the interior zone IZ and the perimeter zone PZ are for each building. An air conditioning system that is cooperatively controlled by the multi air conditioning system 200 may be used.

  Furthermore, the central air conditioning system 100 shown in the above embodiment is applied to the interior zone IZ by applying the central air conditioning system 100 instead of the building multi air conditioning system 200 shown in the above embodiment to the perimeter zone PZ. Instead of the above, the building multi-air conditioning system 200 may be applied, and the interior zone IZ and the perimeter zone PZ may be an air conditioning system in which the two air conditioning systems 100 and 200 perform coordinated control.

  As described above, if the two air conditioning systems are controlled in a coordinated manner, the same effects as those of the present invention can be obtained.

  According to the air conditioning system, the air conditioning control device, and the air conditioning control method according to the present invention, it is possible to effectively suppress mixing loss even when different types of conditioned air are supplied to a continuous space. Therefore, application to an air conditioning system, an air conditioning control device, and an air conditioning control method for performing air conditioning for a space having an interior zone and a perimeter zone is particularly useful.
