A line 1201 indicates the heat load that the air conditioner can handle according to the power consumption. As the power consumption increases as indicated by line 1201, the heat load (air conditioning load) that can be handled also increases. However, as indicated by area 1202, even if the air conditioning load becomes smaller than the predetermined value, power consumption does not decrease. Therefore, in the air-conditioning function power information 112, the heat load at which the power consumption does not decrease even if it is further decreased is set as the minimum settable heat load L2_min. A maximum heat load L2_max that can be set for the air conditioner is also set.

In this embodiment, an example in which the ventilator capacity information 111 and the air conditioning function capacity information 112 are stored in advance will be described. It may be stored in a table format or as an approximate expression.

The control unit 101 acquires the detection result of the temperature detection unit 24 of the air supply unit 20 and the detection result of the temperature detection unit 14 of the exhaust unit 10 via the control unit 52 of the compressor unit 50 . Thereby, the control unit 101 can acquire the temperature in the living room space R11, the outdoor temperature, and the like. Furthermore, the control unit 101 may acquire the temperature or the like detected by a remote controller or the like for operating the air conditioner 2 via the control unit 71 of the outdoor unit 70 .

The control unit 101 calculates a heat load target value (an example of a first heat load) ACL set as a control target in the living room space R11 based on the temperature of the living room space R11. As a calculation method, for example, calculation using Equation (1) is conceivable.

Target heat load value ACL [W] = α(Tout-Tin) + β + (Ve + Vd) x (Hout-Hin) + (CpB x Vb + CpA x V) x (Tin-Tset) (1)

Of the parameters shown in equation (1), the indoor temperature Tin, the outdoor temperature Tout, the indoor air enthalpy Hin, and the indoor air enthalpy Hout are values that can be calculated from the detection results of the temperature detector 14 or the temperature detector 24 . The target temperature Tset is a target temperature set by the user using the remote control of the air conditioner 2 or the like.

Among the parameters shown in formula (1), the building heat capacity CpB, the building capacity Vb, the air heat capacity CpA, the air volume V, the forced ventilation rate Ve, and the draft ventilation rate Vd may be predetermined values or predetermined values. A value obtained as a result of learning may be used.

α is a parameter determined according to the embodiment. β is a parameter determined according to one or more of the amount of heat generated by equipment, the amount of heat generated inside the lighting, the amount of heat generated inside the human body, etc. set in the living room space R11.

Then, the control unit 101 performs settings for sharing the calculated target heat load value ACL between the ventilator 1 and the air conditioner 2 according to the ventilator capacity information 111 and the air conditioner function capacity information 112 .

That is, α(Tout−Tin)+(Ve+Vd)×(Hout−Hin) in equation (1) is the heat load generated by ventilation between the room space R11 and the outdoors, and β+(CpB ×Vb+CpA×V)×(Tin−Tset) is the heat load occurring in the living room space R11. That is, the control unit 101 according to the present embodiment adds the heat load caused by the ventilation between the living room space R11 and the outdoors and the heat load caused in the living room space R11 to obtain the heat load target value ACL is calculated. In this embodiment, power consumption can be reduced by appropriately sharing the total heat load of the living room space R11 and the heat load caused by ventilation.

Further, when setting the ventilator 1 to share part of the heat load target value ACL, the control unit 101 causes the first heat exchanger 22 to function as a condenser or an evaporator, adjust the temperature of the supply air.

For example, the control unit 101 instructs the control unit 52 of the compressor unit 50 so that the measured value of the temperature of the air detected after passing through the first heat exchanger 22 becomes the target temperature Tset. Indicate the number of revolutions. At this time, feedback control may be performed so that the measured value, which changes with time, follows the target temperature Tset.

Then, the control unit 101 subtracts the heat load required for the ventilation device 1 to reach the target temperature Tset from the heat load target value ACL, and the remaining heat load is processed by the air conditioner 2. Identify as a heat load. Then, the control unit 101 calculates operating conditions necessary for the air conditioner 2 to process the identified heat load, and instructs the air conditioner 2 of the specific operating conditions.

Thereby, the heat load target value ACL can be shared between the ventilator 1 and the air conditioner 2 .

In this embodiment, you may use various sharing methods other than the sharing method mentioned above.

The control unit 101 determines that the heat load target value ACL is smaller than the minimum heat load L1_min of the ventilator 1 stored in the ventilator capacity information 111, and the heat load target value ACL is stored in the air conditioning function capacity information 112. If the heat load is smaller than the minimum heat load L2_min of the air conditioner 2 that is present, the operation of the air conditioner 2 is stopped. After that, the control unit 101 performs control to repeatedly operate the ventilator 1 with the ability to cope with the minimum heat load and stop the operation.

Furthermore, the control unit 101 sets the operation time and stop time per unit time so that the average value of the heat load processed per unit time corresponds to the target heat load value ACL. Specifically, the control unit 101 sets the operation time and the stop time so that the thermal load target value ACL=minimum heat load L1_min×(operating time/(operating time+stopping time)). This makes it possible to realize optimum control that satisfies the target heat load value ACL.

That is, in the present embodiment, by alternately repeating operation and shutdown, control can be performed so as to reach the thermal load target value ACL. In addition, the fans 11 and 21 of the ventilation device 1 are always operated to maintain the ventilation of the living room space R11. Since the control described above can prevent the air conditioner 2 from operating at a low load, power consumption can be reduced.

The control unit 101 according to this embodiment may share the heat load according to the operation pattern shown below. In the examples shown in FIGS. 3 to 5, the case where the heat load processing efficiency of the ventilator 1 is higher than the heat load processing efficiency of the air conditioner 2 (the power consumption is small when processing the same load) will be described. .

FIG. 3 is a diagram showing an example of a sharing method by the control unit 101. As shown in FIG. As shown in FIG. 3, the target heat load value ACL (1303) is determined to be greater than or equal to the sum of the minimum heat load L2_min (1301) of the air conditioner 2 and the maximum heat load L1_max (1302) of the ventilator 1. In this case, the maximum heat load L1_max (1302) is assigned to the ventilator 1, and the difference (1304) obtained by subtracting the maximum heat load L1_max of the ventilator 1 from the heat load target value ACL is assigned to the air conditioner 2.

FIG. 4 is a diagram showing an example of a sharing method by the control unit 101. As shown in FIG. As shown in FIG. 4, the heat load target value ACL (1402) was determined to be less than the maximum heat load L1_max (1401) of the ventilation system 1 and equal to or greater than the minimum heat load L1_min (1403) of the ventilation system 1. In this case, all the heat loads 1404 corresponding to the heat load target value ACL (1402) are assigned to the ventilator 1 .

FIG. 5 is a diagram showing an example of a sharing method by the control unit 101. As shown in FIG. As shown in FIG. 5, the heat load target value ACL (1503) is smaller than the sum of the maximum heat load L1_max (1502) of the ventilator 1 and the minimum heat load L2_min (1501) of the air conditioner 2, and the ventilation If it is determined that the maximum heat load L1_max (1504) or more of the device 1 is equal to or greater than the maximum heat load L1_max (1504) of the air conditioner 2, the minimum heat load L2_min is assigned to the air conditioner 2, and the difference ( 1505) is assigned to ventilator 1.

In the examples shown in FIGS. 3 to 5, load efficiency can be improved by allocating the ventilator 1 to handle many loads.

When the heat load is shared with the air conditioner 2 due to reasons such as the heat load target value ACL (1503) being greater than the maximum heat load L1_max of the ventilation device 1, the control unit 101 sets the minimum heat load to the air conditioner 2. The operation corresponding to the heat load L2_min is maintained. As a result, frequent starting and stopping of the thermostat of the air conditioner 2 can be suppressed during interlocking.

In this embodiment, after sharing the heat load target value ACL between the ventilator 1 and the air conditioner 2 and starting operation control, the sharing ratio may be changed according to changes in the situation. For example, when the air-cooling operation is performed by the ventilator 1, the air cooled by the first heat exchanger 22 cools the room in which the first heat exchanger 22 is installed via the first heat exchanger 22. cooling the air of the air supply unit 20, condensation may occur on the surface of the air supply unit 20. In such a case, adjustment is made so that a part of the share of the ventilation device 1 is assigned to the air conditioner 2 .

The control unit 101 receives the temperature of the air measured by the sensor unit provided downstream of the first heat exchanger 22 from the air supply unit 20 via the control unit 52 of the compressor unit 50 .

The control unit 101 receives temperature and humidity data of the living room space R11 from the control unit 71 of the outdoor unit 70 . The temperature and humidity data of the living room space R11 are, for example, data detected by the remote controller of the air conditioner 2 or the like.

Then, the control unit 101 calculates the dew condensation temperature based on the temperature and humidity data of the living room space R11.

Then, the control unit 101 determines whether or not the temperature of the air downstream from the air supply unit 20 to the first heat exchanger 22 is equal to or higher than the dew condensation temperature (an example of a predetermined standard).

When the control unit 101 determines that the temperature of the air downstream of the first heat exchanger 22 is lower than the dew condensation temperature (an example of a predetermined criterion) (if it determines that the predetermined criterion is not satisfied), the controller 101 determines The sharing is reassigned so that the heat load processing capacity of the ventilator 1 is suppressed and the heat load processing capacity of the air conditioner 2 is increased compared to before.

In this embodiment, the control unit 101 of the host controller 100 performs the above-described control, so that the heat load can be appropriately shared between the ventilator and the air conditioner, thereby improving the energy consumption efficiency. can be done.

(Modification 1 of the first embodiment)
In the embodiment described above, an example in which each of the air supply unit 20 and the exhaust unit 10 is provided with one air supply port and one exhaust port has been described. However, this embodiment is not limited to the configuration described above. Therefore, in Modification 1 of the first embodiment, an example in which a plurality of exhaust ports are provided for each of the air supply unit 20 and the exhaust unit 10 will be described.

FIG. 6 is a diagram showing an arrangement example of a ventilation device, an air conditioner, and a host controller according to this modification. In the example shown in FIG. 6, the same reference numerals are assigned to the same configurations as in the above-described embodiment, and the description thereof is omitted.

In this modified example, an air conditioner 2A is provided with three air conditioner indoor units 81, 82, and 83 in an outdoor unit . The control of the air conditioner 2A is the same as that of the air conditioner 2 of the embodiment described above. The air conditioner 2A and the three air conditioner indoor units 81, 82, 83 are connected by a connecting pipe F101.

The ventilator 1A is provided with a compressor unit 50, an exhaust unit 10, and an air supply unit 20. As shown in FIG. The compressor unit 50, the exhaust unit 10, and the air supply unit 20 are connected by a connecting pipe F102.

The exhaust unit 10 is connected to a plurality of exhaust ports 93A-93D via an exhaust duct P102 (an example of a second air flow path).

The air supply unit 20 is connected to a plurality of air supply ports 92A-92D via an air supply duct P101 (an example of a first air flow path).

As a result, since a plurality of air supply ports 92A to 92D and exhaust ports 93A to 93D are arranged in the living room space R51, air can be circulated in the living room space R51, and ventilation efficiency can be improved.

Also, inside the air supply duct P101, an opening/closing damper (an example of a first air volume adjustment mechanism) (not shown) may be provided for each branch flow path divided into each of the air supply ports 92A to 92D. The opening/closing damper adjusts the amount of air supplied to each of the air supply ports 92A to 92D, for example, according to control from the control section 23 of the air supply unit 20. FIG.

Similarly, inside the exhaust duct P102, an opening/closing damper (an example of a first air volume adjustment mechanism) (not shown) may be provided for each of the branch flow paths that are divided for each of the exhaust ports 93A to 93D. The opening/closing damper adjusts the amount of air to be returned to each of the exhaust ports 93A to 93D, for example, according to control from the control section 13 of the exhaust unit 10. FIG.

For example, the host controller 100 controls the control unit 23 of the air supply unit 20 and the control unit 13 of the exhaust unit 10 according to the temperature distribution, humidity distribution, or ventilation situation in the living room space R51. By outputting a control signal indicating the opening/closing of the open/close dampers provided in 92D or each of the air outlets 93A to 93D, the amount of blowing air can be finely adjusted, thereby improving the comfort of the living room space R51 and suppressing power consumption. can be realized.

Also, in this modified example, an example in which an open/close damper is provided for each of the air supply ports 92A to 92D and the exhaust ports 93A to 93D has been described, but an air volume adjustment mechanism other than the open/close dampers may be provided. For example, a blower fan capable of adjusting the air volume may be attached to each of the air supply ports 92A to 92D and the air exhaust ports 93A to 93D.

In the first embodiment, an example in which one ventilation device 1 and one air conditioner 2 are provided has been described. However, the embodiment described above is not limited to an example in which one ventilation device 1 and one air conditioner 2 are provided. Therefore, in the second embodiment, an example in which a plurality of ventilation devices 1 and air conditioners 2 are provided will be described. In addition, description is abbreviate|omitted as it is the same as that of embodiment mentioned above other than that.

In this embodiment, the number of ventilators 1 provided is plural (for example, two). Also, the number of air conditioners 2 provided is plural (for example, two).

The control unit 101 calculates the total power consumption Wtotal using Equation (2) shown below.

Of the variables shown in equation (2), n1 is the number of ventilators 1 and n2 is the number of air conditioners 2 . Power consumption Wo _i of ventilator 1 (power consumption of i-th ventilator 1) = Function1 (Vs, Vr, Tset, Ts, Tr, Lfo _i ), power consumption Wa _i of air conditioner 2 (i-th air conditioner power consumption of machine 2)=Function2(Tset, Ts, Tr, Lfa _i ). Note that Function1 and Function2 are defined according to the embodiment as functions for calculating power consumption.

The parameters expressed by Equation (2) are the air volume Vs supplied by the ventilator 1, the air volume Vr exhausted by the ventilator 1, the outdoor temperature Ts, the temperature Tr of the living room space R11, and the target temperature Tset. The ventilation system load factor Lfo _i =Cfo _i /Comax[W] and the air conditioner load factor Lfa _i =Cfa _i /Carmax[W].

Note that the ventilator capacity Cfo _i indicates the share of the heat load assigned to the i-th ventilator 1 , and the air-conditioning functional power Cfa _i indicates the share of the heat load assigned to the i-th air conditioner 2 .

The maximum capacity (settable maximum heat load) of the ventilator 1 is Comax [W], and the maximum capacity (settable maximum heat load) of the air conditioner 2 is Carmax [W].

Also, ventilator capacity Cfo _i > ventilator minimum capacity (settable minimum heat load) Comin [W], and air conditioning function power Cfa _i > air conditioner minimum capacity (settable minimum heat load) Comin [W]. must be fulfilled.

The maximum capacity of the ventilation system 1 (settable maximum heat load) Comax [W], the maximum capacity of the air conditioner 2 (settable maximum heat load) Carmax [W], the minimum capacity of the ventilation system (settable minimum The heat load) Comin [W] and the minimum capacity (settable minimum heat load) Comin [W] of the air conditioner may be stored in advance in the storage unit as the ventilator capacity information 111 and the air conditioning function capacity information 112. , may be calculated based on the learning result.

The control unit 101 calculates the ventilator load factor Lfo and the air conditioner load factor Lfa that minimize the total power consumption Wtotal. At that time, the condition of formula (3) shown below is satisfied. Thereby, the sharing of the ventilator 1 and the air conditioner 2 is specified.

The heat load target value ACL, the ventilator capacity Cfo _i of the ventilator 1 (the ventilator capacity of the i-th ventilator 1) and the air-conditioning functional power Cfa _i of the air conditioner (the i-th air-conditioning functional power of the air conditioner 2), and , can be expressed by Equation (3). By the calculation described above, the heat load target value ACL is shared between the ventilator 1 and the air conditioner 2 according to the ventilator load factor Lfo _i and the air conditioner load factor Lfa _i .

In addition, the control unit 101 sets the heat load target value ACL (an example of the first heat load) [W] calculated by the above-described formula (1) to the ventilation of a plurality (for example, two units) installed in the present embodiment. If it is smaller than the total value of the minimum capacity Comin [W] of the device 1 and the total value of the minimum capacity Comin [W] of the plurality (for example, two) air conditioners 2 installed in this embodiment, the plurality of air conditioners Stop the operation of 2.

After that, the control unit 101 stops a part (for example, one unit) of the plurality of ventilators 1 and operates the other ventilators 1 (for example, one unit). If the target heat load value ACL>the minimum capacity Comin [W] per unit, the control unit 101 instructs only one ventilator 1 to operate with the heat load corresponding to the target heat load value ACL. , you can achieve your goals.

Note that the fans 11 and 21 of the ventilator 1 are kept in operation at all times.

Further, in the case of target heat load value ACL<minimum capacity Comin [W] per unit, the control unit 101 controls one unit to correspond to the target heat load value ACL, as in the first embodiment. The ventilation system 1 is instructed to repeat operation and stop at the minimum capacity. As a result, low-load operation of the air conditioner 2 can be avoided.

Moreover, when the living room space is large, the heat load may differ depending on the area. FIG. 7 shows the heat load detected for each area. In the example shown in FIG. 7, two ventilators 1A and 1B and two air conditioners 2A and 2B are provided. The host controller 100 controls the two ventilators 1A and 1B and the two air conditioners 2A and 2B.

The ventilator 1A is composed of a compressor unit 50A, an air supply unit 20A, and an exhaust unit 10A. Also, the ventilator 1B is composed of a compressor unit 50B, an air supply unit 20B, and an exhaust unit 10B.

The air conditioner 2A is composed of an outdoor unit 70A and an air conditioner indoor unit 81A. The air conditioner 2B is composed of an outdoor unit 70B and an air conditioner indoor unit 81B.

In the example shown in FIG. 7, a cooling load (a heat load that needs to be removed by controlling the temperature to reach the target temperature) is generated in region R101A of living room space R101, and a heating load is generated in region R101B. (the heat load that must be given by the control that raises the temperature to reach the target temperature).

In such a case, if cooling is performed by the ventilator 1A and the air conditioner 2A that exist in the region R101A, and heating is performed by the ventilator 1B and the air conditioner 2B that exist in the region R101B, power consumption increases. .

Therefore, the control unit 101 according to the present embodiment adds all of the heat load target values (for example, the cooling load of the region R101A and the heating load of the region R101B) occurring in each region of the living room space R101, and the total value is A certain heat load target value is shared by two ventilators 1A and 1B and two air conditioners 2A and 2B.

As a result, even when the cooling load and the heating load are mixed in the same air conditioning zone (for example, the living room space R101), the heat load can be shared based on the total of the cooling load and the heating load. Improve power efficiency.

Also, the control of the ventilators 1A and 1B is made different depending on whether the total heat load target value is the cooling load or the heating load.

That is, when the total heat load target value is the cooling load, the control unit 101 according to the present embodiment evaporates the first heat exchangers 22 of the air supply units 20A and 20B of the plurality of ventilators 1A and 1B. and the second heat exchangers 12 of the exhaust units 10A and 10B function as condensers.

On the other hand, when the total heat load target value is the heating load, the control unit 101 according to the present embodiment condenses the first heat exchangers 22 of the air supply units 20A and 20B of the plurality of ventilators 1A and 1B. and the second heat exchangers 12 of the exhaust units 10A and 10B function as evaporators.

Further, the control unit 101 changes the sharing of the heat load according to the positions where the ventilators 1A and 1B are installed.

When the control unit 101 determines that the total heat load target value (an example of the first heat load) is the cooling load, the control unit 101 takes in air from the lower temperature region of the plurality of ventilators 1A and 1B. 2. Set the load sharing of the ventilator containing heat exchanger 2 to be greater than the load sharing of the other ventilators.

In the example shown in FIG. 7, the ventilator 1B provided in the heating load region R101B (the region requiring heating, in other words, the region where the temperature is low) shares a larger heat load than the ventilator 1A. That is, since the temperature of the exhausted air is low, the heat dissipation efficiency can be increased.

When the control unit 101 determines that the total heat load target value (an example of the first heat load) is the heating load, the control unit 101 takes in air from the high temperature region of the plurality of ventilators 1A and 1B. The load sharing of the ventilator 1A including two heat exchangers is set to be greater than the load sharing of the other ventilator 1B.

In the example shown in FIG. 7, the ventilation device 1A provided in the cooling load region R101A (the region requiring cooling, in other words, the region having a high temperature) shares a larger heat load than the ventilation device 1B. That is, since the temperature of the exhausted air is high, heat radiation efficiency can be increased.

(Third Embodiment)
In addition to the embodiments described above, there are other arrangements of ventilation devices and air conditioners. Therefore, in the third embodiment, various arrangements of ventilation devices and air conditioners will be described. In the third embodiment, an example in which a host controller 100, a ventilator 1B, and an air conditioner 2B are installed. The internal configurations of the host controller 100, the ventilator, and the air conditioner are the same as in the above-described embodiment, and the description thereof is omitted.

FIG. 8 is a diagram showing an example of a region to be processed of the ventilator 1B and a region to be processed of the air conditioner 2B according to the third embodiment. In the example shown in FIG. 8, the living room space R201 is divided into 4×4=16 regions.

The ventilator 1B treats a region R211 corresponding to the living room space R201 as a region to be processed, and the air conditioner 2B treats 16 regions R211A to R211P corresponding to the living room space R201 as regions to be processed.

FIG. 9 is a diagram showing an example of a region to be processed of the ventilator 1B and a region to be processed of the two air conditioners 2B. The ventilator 1B uses a region R211 corresponding to the living room space R201 as a region to be processed. One of the two air conditioners 2B has eight regions R211A to R211H as processing target regions, and the other has eight regions R211I to R211P as processing target regions.

FIG. 10 is a diagram showing an example of a region to be processed of two ventilators 1B and a region to be processed of an air conditioner 2B.

One of the two ventilators 1B has a region R211Q to be processed, and the other has a region R211R to be processed. The air conditioner 2B has 16 regions R211A to R211P as regions to be processed.

The host controller 100 performs interlocking control when the user performs interlocking setting to the host controller 100 for the correspondence relationship between the target regions of the ventilation device 1B and the air conditioner 2B shown in FIGS. 8 to 10 . be able to.

As for interlocking settings, the user can use a controller (not shown) or the like to select heat sources for air conditioners and ventilators for which interlocking control is to be performed for each region to be processed, based on input position information of the region to be processed. Associate. As a result, interlocking control of the ventilator 1B and the air conditioner 2B by the host controller 100 can be realized.

In this embodiment, interlocking control is enabled when the same zone such as the living room space R201 is entirely covered with the treated area of the air conditioner 2B or the treated area of the ventilator 1A of the same heat source. This embodiment is an example in which the lesser of the ventilator 1B and the air conditioner 2B is one, and the greater one is up to two, but it is not limited to this aspect.

Next, a processing procedure performed by the host controller 100 according to this embodiment will be described. FIG. 11 is a flow chart showing a processing procedure performed by the host controller 100 according to this embodiment.

First, the host controller 100 calculates the load target value in the living room space R201 (S2101). The calculation method of the load target value is the same as in the above-described embodiment, and the description thereof is omitted.

Next, the host controller 100 calculates the ventilator load factor and the air conditioner load factor (S2102). A specific calculation method for the ventilation device load factor and the air conditioner load factor will be described later.

Next, based on the ventilator load factor and the air conditioner load factor, the host controller 100 transmits the target processing load, in which the load target value is shared by each device, to the ventilator 1B and the air conditioner 2B (S2103). .

Then, the ventilator 1B performs control with a processing capacity corresponding to the target processing load (S2104).

The air conditioner 2B controls with the processing capacity corresponding to the target processing load when temperature control is being performed, and maintains the temperature control stop state when temperature control is stopped (S2105).

Then, the host controller 100 determines whether or not a predetermined condition is satisfied (S2106).

As the predetermined condition, the average value of two or more indoor units connected to the outdoor unit whose temperature control is stopped for a predetermined period (for example, 5 minutes) is "the temperature of the air being sucked in < Assume that "target temperature - A (eg, 1.0 degrees)" or "temperature of sucked air>target temperature - B (eg, 1.0 degrees)" is satisfied.

In addition, as another predetermined condition, as an integrated value for a certain period of time (for example, 5 minutes) of the indoor units connected to the outdoor unit operating the temperature control, the "integrated value of processing capacity for a certain period of time - Assume that the integrated value of the target processing load for a certain period of time)>C (for example, 0.2)×(the integrated value of the target processing load for a certain period of time) is satisfied.

In other words, when the host controller 100 determines that the predetermined condition indicating that there is a large deviation from the current situation is satisfied (S2106: Yes), the process is repeated from S2101.

On the other hand, if the upper control device 100 determines that the predetermined condition is not satisfied (S2106: No), it continues the current process and performs the determination of S2106 again after 5 minutes.

Next, a method for calculating the sharing ratio according to the present embodiment will be described. In this embodiment, instead of the method shown in the second embodiment, the ventilator 1B is simply fixed to the target capacity, and the air conditioner 2B calculates the sharing ratio by the method shown below. good too.

First, if the suction temperature of the air conditioner 2B < target temperature - A (eg, 1.0 degrees), it is defined as a heating load, and if the suction temperature of the air conditioner 2B > target temperature + B (eg, 1.0 degrees) , is defined as the cooling load. It should be noted that the target temperature is assumed to be the temperature set by a remote controller or the like.

In the modified example, the lesser of the heat sources of the ventilator 1B or the air conditioner 2B is one system or less, and the greater one is also limited to two systems, the following combinations are conceivable.

That is, in this modified example, there are 1) a combination of two ventilators/one air conditioner and 2) a combination of one ventilator and two air conditioners.

1) In the case of two ventilators/one air conditioner, the load factor of the two ventilators is assumed to be the same. In this case, calculation can be performed by the same calculation as in the first embodiment, so the calculation load can be reduced.

2) In the case of a combination of a ventilator (one unit) and air conditioners (two units), the following three situations are conceivable as operations.

Situation 1 includes the case of the first air conditioner 2B_1 (operating), the second air conditioner 2B_2 (operating), and the ventilator 1B (operating). In such a case, the load factors of the first air conditioner 2B_1 and the second air conditioner 2B_2 are matched. Then, the ventilator load factor and the air conditioner load factor are calculated. The calculation load can be reduced by matching the load factors.

Situation 2 includes the case of the first air conditioner 2B_1 (operation), the second air conditioner 2B_2 (stop), and the ventilator 1B (operation). In this case, the load is shared between the first air conditioner 2B_1 (operation) and the ventilator 1B (operation). In this case, the load can be shared in the same procedure as in the first embodiment.

Situation 3 includes the case of the first air conditioner 2B_1 (stopped), the second air conditioner 2B_2 (operating), and the ventilator 1B (operating). In this case, the load is shared between the second air conditioner 2B_2 (operation) and the ventilator 1B (operation). In this case, the load can be shared in the same procedure as in the first embodiment.

If the load factors of the first air conditioner 2B_1 and the second air conditioner 2B_2 cannot be set to 0 (due to the state of the indoor units), the processes of the situations 2 and 3 are not performed. For example, when there are N (for example, two) or more indoor units connected to the same outdoor unit, the load factor of the air conditioner cannot be set to "0".

The load factor calculated last time is "0" and the load factor is set to "0" as long as the heat source (for example, outdoor air conditioner) which can be set to "0" is not insufficient in capacity. That is, in the present embodiment, control is performed to lengthen the thermostat OFF time.

By setting the load factor and the load sharing according to the above-described definitions for each situation, it is possible to reduce the calculation load when calculating the load factor according to the procedure shown in the above-described embodiment.

(Fourth embodiment)
In the embodiment described above, the case where the temperature is adjusted by cooperative control by the host controller 100 has been described. However, the embodiments described above are not limited to temperature control. Therefore, in the fourth embodiment, adjustment of humidity will be described.

For example, the host controller 100 acquires the necessary amount of humidification or dehumidification in a region R101A (an example of a first region) in the living room space R101 shown in FIG. Similarly, the host controller 100 acquires the necessary amount of humidification or dehumidification in the area R101B (an example of the second area).

Then, the host controller 100 adds the required humidification or dehumidification amount in the region R101A (an example of the first region) and the required humidification or dehumidification amount in the region R101B (an example of the second region), Based on the humidification amount or dehumidification amount, the temperature using the first heat exchanger 22 of the ventilation device 1B and the heat exchanger (an example of the third heat exchanger) of the air conditioner 2B (e.g., the evaporation temperature of the refrigerant) control. Further, when humidification is required, water supply control may be performed on the air supply unit 20 or the air conditioner 2B.

In this embodiment, power consumption efficiency is improved by performing temperature control based on the sum of the dehumidification amount and the humidification amount calculated for each region.

(Modification 1 of the fourth embodiment)
The host controller 100 may also perform humidity control in consideration of the humidity distribution in the living room space R101. In this embodiment, input of the target humidity is received from the remote controller or the like of the air conditioner 2B. The air conditioner 2B transmits the inputted target humidity to the host controller 100 .

In this embodiment, it is assumed that the humidity for each position is obtained from a combination of the absolute humidity and the relative humidity distribution.

In the same air conditioning zone as shown in FIG. 7, moisture and air circulate and diffuse, and moisture diffuses due to the difference in concentration of absolute humidity. Although the absolute humidity is almost uniform, if there is a temperature distribution in the air conditioning zone, a distribution of relative humidity occurs according to the temperature distribution. Especially in winter, the room temperature near the window drops, so the relative humidity rises and dew condensation occurs on the window surface.

Therefore, the host controller 100 calculates the relative humidity distribution within the living room space R101 based on the temperature distribution. In this embodiment, any method may be used to calculate the relative humidity distribution. For example, from the detection results of temperature detection units (not shown) provided in each of the exhaust units 10A and 10B, the air supply units 20A and 20B, and the air conditioning indoor units 81A and 81B in the living room space R101, the relative temperature in the living room space R101 A typical humidity distribution may be calculated.

A case in which the user controls the temperature and humidity in the living room space R101 having such a temperature distribution using one remote controller will be described.

When the remote controller of the air conditioner 2B receives input of the indoor target temperature and target humidity from the user, the air conditioner 2B transmits the input target temperature and target humidity in the reference room to the host controller 100 .

Then, the host controller 100 calculates the average humidity from the temperature measured by the remote controller and each device and the relative humidity distribution. The average humidity is the humidity when it is assumed to be uniform within the living room space R101.

Then, the host controller 100 calculates the necessary amount of humidification or dehumidification as an overall average from the difference between the calculated average humidity and the input target humidity.

Then, the host controller 100 supplies air to the ventilation device 1B so that the average humidity of the indoor space becomes the input target humidity, and humidification or dehumidification is performed according to the calculated humidification amount or dehumidification amount. Perform humidity control using at least one of the unit 20 and the heat exchanger (an example of the third heat exchanger) of the air conditioner 2B. When humidification is required, the host controller 100 controls the ventilation device 1B The water supply control may be performed for the air supply unit 20 of .

Further, when a plurality of ventilators are provided and the host controller 100 recognizes the arrangement information of the air supply units 20 of the ventilators, control may be performed based on the arrangement. For example, when performing dehumidification or humidification by the above-described processing, the host controller 100 blows off low-humidity air from the air supply unit near the window, and blows off high-humidity air from the air supply unit 20 far from the window. may be controlled. As a result, it is possible to suppress the occurrence of dew condensation on the window surface, and to suppress the moisture loss due to the dew condensation. It should be noted that the same control is performed when the air conditioner 2B is used, and a description thereof will be omitted.

(Fifth embodiment)
FIG. 12 is a diagram exemplifying the arrangement of a device group including the upper control device 300 according to the fifth embodiment. The example shown in FIG. 12 includes at least living room spaces R301, R302, R303, restrooms R304, R305, and a pipe shaft R306.

Ventilation fans 395 and 396 are provided in restrooms R304 and R305, respectively. When the ventilation fans 395 and 396 are operating, the air in the restrooms R304 and R305 is discharged to the outside. This control is performed by the host controller 300 .

Living room spaces R301 and R302 are provided with ventilation devices and air conditioners (not shown).

A ventilation device 1C and an air conditioner 2C are provided in the living room space R303.

In addition, the air conditioner 2C includes one outdoor unit 370 and three air conditioner indoor units 381, 382, and 383. One outdoor unit 370 and three air conditioning indoor units 381 to 383 are connected by connecting pipes.

Also, the outdoor unit 370 is connected to the host controller 300 via a signal line. Thereby, one outdoor unit 370 can perform air conditioning control according to the control of the host controller 300 .

The ventilation device 1</b>C is a ventilation device provided in the living room space R<b>303 and includes a compressor unit 350 , an air supply unit 320 and an exhaust unit 310 .

The air supply unit 320 supplies air (SA) from four air supply ports 392A to 392D. The exhaust unit 310 returns air (RA) from four exhaust ports 391A to 391D.

Compressor unit 350, air supply unit 320, and exhaust unit 310 are connected by a connecting pipe. The communication pipe includes a plurality of refrigerant communication pipes. Thereby, the refrigerant can be circulated among the compressor unit 350 , the air supply unit 320 and the exhaust unit 310 .

Further, the compressor unit 350, the air supply unit 320, and the exhaust unit 310 are connected by signal lines (not shown). This enables information to be transmitted and received between units. Further, the configurations inside the compressor unit 350, the air supply unit 320, and the exhaust unit 310 are the same as those of the compressor unit 50, the air supply unit 20, and the exhaust unit 10 shown in FIG. 1, and the description thereof is omitted.

Compressor unit 350 is arranged on pipe shaft R306.

The host controller 300 is connected to the compressor unit 350 by signal lines. As a result, the host controller 300 can recognize the state of each device of the ventilator 1C and control each device.

FIG. 13 is a diagram exemplifying the arrangement of the device group in the living room space R303 according to the fifth embodiment. In the example shown in FIG. 13, an air conditioner 2C and a ventilator 1C are arranged.

The air conditioner indoor units 381, 382, and 383 included in the air conditioner 2C are arranged in a line near the center of the living room space R303.

Four air supply ports 392A to 392D, which are the air supply destinations of the air supply unit 320, are provided on the lower side (for example, south side) of the air conditioning indoor units 381, 382, and 383 in FIG.

The four air supply ports 392A to 392D incorporate a fan (an example of a first air volume adjustment mechanism) that adjusts the amount of air supplied to each air supply port. The fan is controlled by the host controller 300 .

Four exhaust ports 391A to 391D, which are air intake ports of the exhaust unit 310, are provided above (for example, the north side) of the air conditioning indoor units 381, 382, and 383 in FIG.

Each of the four exhaust ports 391A to 391D incorporates an open/close damper (an example of a second air volume adjustment mechanism) that adjusts the amount of air taken in by each exhaust port. The opening/closing damper is controlled by the host controller 300 .

That is, the host controller 300 according to the present embodiment controls the corresponding fan for each of the four air supply ports 392A to 392D according to the detection result from the living room space R303, and controls the four air outlets 391A to 392D. Each 391D controls the corresponding open/close damper.

In the present embodiment, the amount of blown air can be finely adjusted in the living room space R303, so it is possible to improve comfort and reduce the amount of energy used.

In this embodiment, the upper control device 300 uses the same method as in the above-described embodiment,
A heat load target value ACL is calculated. Then, the host controller 300 shares the heat load target value ACL between the air conditioner 2C and the ventilator 1C.

Then, the host controller 300 causes the air conditioner 2C and the ventilator 1C to perform processing corresponding to the shared heat load, and controls the four air supply units so that the ventilation airflow in the living room space R303 is in an ideal state. The air supply volume of the air ports 392A to 392D and the exhaust air volume of the four air outlets 391A to 391D are calculated and set. The air supply air volume and exhaust air volume that make the ventilation airflow ideal are determined according to the embodiment such as the arrangement relationship of the four air supply ports 392A to 392D and the four air exhaust ports 391A to 391D. Description is omitted.

For example, the air volume (air volume) blown out from the four air supply ports 392A to 392D is controlled so that the total volume is constant regardless of the distribution, or the air volume taken in from the four air exhaust ports 391A to 391D. (Air volume) is similarly controlled so that the total volume is constant.

Furthermore, the host controller 300 keeps the ratio between the total amount of air blown out from the four air supply ports 392A to 392D and the total amount of air taken in from the four air outlets 391A to 391D constant. Control.

The host controller 300 according to the present embodiment provides first position information indicating the position of each of the four air supply ports 392A to 392D and second position information indicating the position of each of the four air outlets 391A to 391D. and are stored in the storage unit 102 . Furthermore, the host controller 300 may store the shape of the living room space R300 in the storage unit 102. FIG.

As a result, the host controller 300 controls the air supply port 392A based on the positions of the air supply ports 392A to 392D indicated by the first positional information and the positions of the air outlets 391A to 391D indicated by the second positional information. 392D and the opening/closing dampers of the air outlets 391A to 391D are controlled. A specific control method will be described later.

Thereby, the host controller 300 can implement ventilation control considering the positions of the four air supply ports 392A to 392D and the four air outlets 391A to 391D.

For example, the host controller 300 can adjust the amount of air blown out from the four air supply ports 392A to 392D and the amount of air taken in from the four air outlets 391A to 391D according to time. good. That is, since the airflow in the living room space R303 changes with time in a complicated manner, it is possible to make the temperature in the living room space R303 uniform by adjusting according to time.

The host controller 300 adjusts the amount of air blown out from the four air supply ports 392A to 392D and the amount of air taken in from the four air outlets 391A to 391D, and adjusts the air volume in the living room space R303. Ventilation airflow may be controlled according to heat load distribution.

For example, when the heat load target value ACL is a cooling load, the host controller 300 increases the amount of air taken in by one of the exhaust ports 391A to 391D, which are arranged near a region where internal heat generation is large. The heat in the room can be effectively discharged.

The host controller 300 may increase the amount of air to be supplied to one of the air supply ports 392A to 392D that is remote from the one of the exhaust ports 391A to 391D that has increased the amount of air to be taken in. Similarly, host controller 300 may increase the amount of air taken in by exhaust ports 391A-391D remote from one of intake ports 392A-392D that increases the amount of air supplied. As a result, short cuts in ventilation can be prevented, and efficient ventilation can be achieved.

As another example, when the heat load target value ACL is the heating load, the host controller 300 increases the amount of air supplied to one of the air supply ports 392A to 392D near the area where internal heat generation is large. .

Also, the host controller 300 may perform ventilation control based on the temperature distribution.

In this embodiment, a temperature sensor is installed at each of the air supply ports 392A-392D and the air exhaust ports 391A-391D.

Then, the host controller 300 can acquire the temperature near each of the air supply ports 392A to 392D and the exhaust ports 391A to 391D from the detection results from the installed temperature sensors. In addition, it is desirable that the mounting position of the temperature sensor is away from the air path of the blown air. As long as it blows out a mixture of the indoor air and the outside air, it may be on the air path of the blown air.

An example in which the host controller 300 is provided with a temperature sensor for each of the air supply ports 392A to 392D and the exhaust ports 391A to 391D will be described. It may be placement.

Then, the host controller 300 is provided near a region where there is a large difference between the temperature of each region indicated by the temperature distribution of the living room space R303 based on the detection results of the plurality of temperature sensors and the input target temperature. A fan (an example of a first air volume adjustment mechanism) corresponding to one of the air supply ports (for example, one of the air supply ports 392A to 392D) is operated so that the amount of air supplied from the fan of the other air supply port is Control to grow.

Alternatively, the host controller 300 is provided in the vicinity of a region where there is a large difference between the temperature of each region indicated by the temperature distribution of the living room space R303 based on the detection results of the plurality of temperature sensors and the input target temperature. The open/close damper (an example of the second air volume adjustment mechanism) corresponding to the exhaust port (for example, one of the exhaust ports 391A to 391D) is set so that the amount of air taken in is larger than that of the open/close damper for the other exhaust ports. Open control.

In this embodiment, by finely adjusting the amount of blown air or the amount of air taken in, it is possible to prevent localized heating, improve comfort, and reduce energy consumption.

The host controller 300 of the present embodiment may perform control according to a user's request in addition to the above-described control for uniforming the temperature of the air in the living room space R303.

For example, the host controller 300 may display the shape of the living room space R303 and the positions of the air supply ports 392A to 392D and the air exhaust ports 391A to 391D on the touch panel of the user's portable terminal.

Then, when receiving the input information to the touch panel of the mobile terminal, the host controller 300, according to the input information, the amount of air supplied to each of the air supply ports 392A to 392D and the air exhaust ports 391A to 391D and You can freely adjust the amount of air to be exhausted.

When the user feels that the supplied air is cold in a specific place while the ventilation device 1C is performing cooling operation, the user operates the touch panel of the mobile terminal to open the surrounding air supply port (for example, the air supply port 392A 392D) can be reduced to improve comfort.

If you feel that the temperature is cold in a specific place while performing heating operation with the ventilation device 1C, increase the amount of air supplied from the surrounding air supply ports (air supply ports 392A to 392D). can improve comfort.

The host controller 300 automatically controls the amount of air taken in through the exhaust ports 391A to 391D, thereby preventing short-circuiting of air supply and exhaust. For example, when the amount of air supplied from a predetermined air supply port increases, the exhaust air volume of an exhaust port far from the predetermined air supply port is increased.

For example, the host controller 300 may increase the ventilation air volume in areas where there are many people in the room and decrease the ventilation air volume in areas where there are few people in the room. Thereby, ventilation can be performed efficiently.

(Modification 1 of the fifth embodiment)
Also, the configuration for ventilation is not limited to the configuration described above, and may include additional configurations.

FIG. 14 is a diagram exemplifying the arrangement of the device group in the living room space R303 according to Modification 1 of the fifth embodiment. In the example shown in FIG. 14, an air exchange duct is provided in addition to the configuration described in the fifth embodiment.

In the example shown in FIG. 14, a heating load region R303A and a cooling load region R303B exist in a living room space R303.

In the present embodiment, from the ventilation port (an example of the first opening) provided near the air supply port 392D in the cooling load region R303B of the living room space R303, to the heating load region R303A of the living room space R303. A duct (an example of a third air flow path) P401 for conveying air to a ventilation opening (an example of a second opening) is provided.

A blower fan 495 is provided on the path of the duct (an example of the third air flow path) P401.

The host controller 400 can adjust the amount of air flowing through the duct P401 using the blower fan 495 in addition to the control shown in the above-described embodiments. By controlling the blower fan 495, the host controller 400 shifts the air from the cooling load region R303B to the heating load region R303A (in other words, the heating load region R303A). The air can be conveyed to the area below the target temperature as needed.

As a result, in this embodiment, the air in the living room space R303 can be agitated, the temperature and humidity can be made uniform, and localized heating can be suppressed.

Furthermore, in the living room space R303, a device capable of agitating air (such as a circulator) may be installed instead of the duct. The host controller 400 may interlock and control the ventilator 1C and a device capable of agitating air.

The circulator has an elongated cylindrical shape extending from near the ceiling to near the floor, and contains one or more blowers inside the cylinder. As a result, the air can be agitated between the vicinity of the ceiling and the vicinity of the floor.

During cooling, the host controller 400 sucks in the vicinity of the underfloor and blows out the vicinity of the ceiling by means of the circulator. During heating, the host controller 400 draws air from the vicinity of the ceiling and blows it out from the vicinity of the floor by means of the circulator.

As a result, the temperature distribution in the room can be resolved three-dimensionally by forming a vertical airflow with the circulator. Furthermore, the blower fans (not shown) in the air conditioner indoor units 381 to 383 of the air conditioner 2C may also be interlocked to control the air volume.

(Modification 2 of the fifth embodiment)
In the modification 1 of the fifth embodiment, an example of performing heat exchange between regions by stirring air has been described. However, heat exchange between zones is not limited to air agitation. Therefore, in this modified example, a case in which heat is exchanged using a refrigerant will be described.

FIG. 15 is a diagram illustrating the arrangement of device groups in living room spaces R301 and R303 according to modification 2 of the fifth embodiment. In the example shown in FIG. 15 , an exhaust unit 521 including a heat exchanger (an example of a fourth heat exchanger) functioning as a condenser or an evaporator in a living room space R302 (an example of a seventh region of an indoor space), A device (heat transfer device example) is provided.

In the example shown in FIG. 15, the exhaust unit 521 and the air supply unit 511 are connected by a connecting pipe, and a compressor unit 551 is provided between the connecting pipes. Furthermore, an outdoor unit 571 is connected to the air supply unit 511 .

The host controller 500 controls the exhaust unit 521, the air supply unit 511, and the compressor unit 551 in addition to the processing of the above-described embodiment.

The host controller 500 causes the heat exchanger (an example of a fourth heat exchanger) in the exhaust unit 521 to function as either a condenser or an evaporator, and the heat exchanger (fifth heat exchanger) in the air supply unit 511. An example of an exchanger) functions as either one of a condenser and an evaporator. Thus, heat can be transferred between the cooling load region R303C of the living room space R303 and the heating load region R3032A of the living room space R302.

That is, by moving the excess heat in the heating load region R303C of the living room space R303 and the cooling load region R303C of the living room space R302 to the heating load region R302A that requires heat, the air conditioning efficiency in the building is increased. can be improved.

Further, the heat exchange is not limited to using a refrigerant, and the host controller 500 may control air to be blown from the living room space R303 to the living room space R302 using a duct containing a blower fan.

(Modification 3 of the fifth embodiment)
In the above-described embodiment, the air supply amount and exhaust amount are adjusted for each living room space. However, the adjustment method is not limited to this method, and the air supply amount and exhaust amount may be adjusted in consideration of the living room space inside the building. This modified example will be described with reference to FIG. 12 .

In the example shown in FIG. 12, the amount of air that is taken in from the outdoors into the air supply unit 320 and flows from the first heat exchanger 22 to the living room space R303 through the duct (an example of the first air flow path) is calculated as follows: A fan 21 to be adjusted (an example of a third air volume adjustment mechanism) is provided, and in the exhaust unit 310, air flows from the living room space R303 through a duct (an example of a second air flow path) to the outside from the second heat exchanger 12. A fan 11 (an example of a fourth air volume adjustment mechanism) for adjusting the air volume is provided.

Then, the host controller 300 is supplied with air by the fan 21 (third air volume adjustment mechanism) based on the amount of air supplied or exhausted by devices other than the ventilator 1C (for example, ventilation fans 395 and 396). The amount of air and the amount of air taken in by the fan 11 (fourth air volume adjustment mechanism) are set to be different.

For example, the restrooms R304 and R305 are provided with ventilation fans (an example of a ventilation mechanism) 395 and 396 for exhausting air from the restrooms R304 and R305 to the outside. A predetermined amount of air is discharged from the ventilation fan.

Therefore, the host controller 300 adjusts the amount of air exhausted by the ventilator 1B and the amount of air supplied by the ventilator 1B based on the amount of air exhausted by the ventilation fans (an example of the ventilation mechanism) 395, 396. FIG.

Specifically, the host controller 300 adjusts the amount of air supplied by the air supply unit 320 = the amount of air exhausted by the exhaust unit 310 + the amount of air exhausted by the ventilation fans 395 and 396 .

Further, when the amount of air exhausted by the ventilation fans 395 and 396 changes, the host controller 300 adjusts the amount of air exhausted and the amount of air taken in by the ventilation device 1B in accordance with the change. As a result, the air supply and exhaust air in the building can be balanced.

(Modification 4 of the fifth embodiment)
In this modified example, a case will be described in which the host controller 300 controls a plurality of (for example, three) ventilators 1C.

An exhaust unit 310 and an air supply unit 320 are provided in each of the plurality of (for example, three) ventilators 1C.

Then, the host controller 300, in a building (an example of an indoor space),
The amount of air supplied by the fan 21 of the air supply unit 320 provided for each of the plurality of ventilation devices 1C and the amount of air taken in by the fan 11 of the exhaust unit 310 provided for each of the plurality of ventilation devices 1C are Adjust so that they are approximately the same.

As a specific method, the host controller 300 makes adjustments such that the total amount of supplied air≈the total amount of exhausted air in the plurality of ventilators 1C.

Then, when increasing the amount of air supplied by one of the air supply units 320, the host controller 300 reduces the air amount of the other air supply unit 320 by the amount of the increase in one.

Moreover, in order to stabilize the heat balance between the supply air and the exhaust air, the host controller 300 increases the amount of air exhausted from the exhaust unit 310 paired with the supply unit 320 having the increased amount of air. Similarly, the amount of air exhausted from the exhaust unit 310 paired with the air supply unit 320 having the reduced air amount is reduced.

As another method, when the amount of air supplied by the air supply unit 320 is increased in the plurality of ventilators 1C, the host controller 300 increases the amount of air supplied by the air supply unit 320, and the exhaust unit 310 Increases the amount of air exhausted by Such control allows a balance to be maintained between the total amount of air supplied and the amount of air exhausted.

(Sixth embodiment)
In the above-described embodiment, an example has been described in which an air conditioner and a ventilator are provided in one living room space and coordinated control is performed by a host controller. In contrast, in the sixth embodiment, an example in which two air conditioners are provided will be described.

FIG. 17 is a diagram showing an arrangement example of a host controller 700 and two air conditioners 2E_1 and 2E_2 according to the sixth embodiment. In the example shown in FIG. 17, a living room space R700 is provided with multiple systems of air conditioners. In the example shown in FIG. 17, an air conditioner 2E_1 is provided in a region (referred to as a perimeter zone) that is easily affected by the environment from the outside in the living room space R700, and a region that is less affected by the environment from the outside (interior zone) is provided with an air conditioner 2E_2. Since the heat load differs depending on the installation area, the air conditioning capacity of the air conditioner 2E_1 and the air conditioner 2E_2 is different.

The air conditioner 2</b>E_<b>1 includes an outdoor unit 771 and an air conditioner indoor unit 781 . The air conditioner indoor unit 781 takes in air in the perimeter zone of the living room space R700 and exhausts the air, which has undergone heat exchange with the refrigerant flowing through the heat exchanger, to the perimeter zone of the living room space R700.

The air conditioner 2</b>E_<b>2 includes an outdoor unit 772 and an air conditioner indoor unit 782 . The air conditioning indoor unit 782 takes in air in the interior zone of the living room space R700 and exhausts the air, which has undergone heat exchange with the refrigerant flowing through the heat exchanger, into the interior zone of the living room space R700.

The host controller 700 controls two air conditioners 2E_1 and 2E_2.

The host controller 700 includes a control section 701 and a storage section 702 . A control unit 701 performs overall control.

The storage unit 702 stores air conditioning function power information 711 of the air conditioner 2E_1 and air conditioning function power information 712 of the air conditioner 2E_2.

The air-conditioning function capacity information 711 is capacity information (example of first air-conditioning capacity) indicating the correlation of the air conditioning capacity that can be output corresponding to the power consumption of the air conditioner 2E_1.

The air conditioning function capacity information 711 includes the minimum air conditioning capacity Th1min that can be set based on the power consumption of the air conditioner 2E_1 among the air conditioning capacities that can be output by the air conditioner 2E_1. includes the maximum air conditioning capacity Th1max that can be set by the air conditioner 2E_1 among the heat loads that can be output.

The air-conditioning function capacity information 712 is capacity information (example of second air-conditioning capacity) indicating the correlation of the air conditioning capacity that can be output corresponding to the power consumption of the air conditioner 2E_2.

The air conditioning function capacity information 712 includes the minimum air conditioning capacity Th2min that can be set based on the power consumption of the air conditioner 2E_2 among the air conditioning capacities that can be output by the air conditioner 2E_2. includes the maximum air conditioning capacity Th2max that can be set by the air conditioner 2E_2 among the heat loads that can be output.

FIG. 18 is a diagram showing the correspondence relationship between the power consumption and the air conditioning capacity (correspondable heat load) in the air conditioning capacity information 711 and the air conditioning capacity information 712. In FIG. A line 3201 indicates the air conditioning capacity (heat load that can be handled) that the air conditioner 2E_1 can output according to power consumption. As shown by line 3201, as the power consumption increases, the air conditioning capacity that can be output also increases. Even if the air conditioning capacity becomes smaller than the air conditioning capacity Th1min, the power consumption does not decrease. Therefore, the air conditioning capacity Th1min is set as the minimum air conditioning capacity (correspondable heat load). A maximum air conditioning capacity Th1max that can be output to the air conditioner 2E_1 is also set.

A line 3202 indicates the air conditioning capacity (heat load that can be handled) that the air conditioner 2E_2 can output according to power consumption. As the power consumption increases as indicated by line 3202, the air conditioning capacity that can be output also increases. Even if the air conditioning capacity becomes smaller than the air conditioning capacity Th2min, the power consumption does not decrease. Therefore, the air conditioning capacity Th2min is set as the minimum air conditioning capacity (correspondable heat load). A maximum air conditioning capacity Th2max that can be output to the air conditioner 2E_2 is also set.

As shown in FIG. 18, the maximum air conditioning capacity Th1max of the air conditioner 2E_1>the maximum air conditioning capacity Th2max of the air conditioner 2E_2, and the minimum air conditioning capacity Th1min of the air conditioner 2E_1>the minimum air conditioning capacity Th2min of the air conditioner 2E_2. be.

As shown in FIG. 18, the power consumption corresponding to the air conditioning capacity of the air conditioner 2E_2 is smaller than the power consumption corresponding to the air conditioning capacity of the air conditioner 2E_1 up to the maximum air conditioning capacity Th2max of the air conditioner 2E_2.

The control unit 701 acquires temperature detection results from the air conditioner indoor units 781 and 782 of the air conditioners 2E_1 and 2E_2 and the remote controllers via the outdoor units 771 and 772, respectively. The control unit 701 can acquire the temperature and the like in the living room space R700.

The control unit 101 calculates a heat load target value (an example of a first heat load) ACL set as a control target in the living room space R700 based on the temperature of the living room space R700.

Then, the control unit 101 processes the calculated heat load target value (example of the first heat load) ACL using the air conditioning capacities of the air conditioners 2E_1 and 2E_2.

For example, when the calculated heat load target value (example of the first heat load) ACL is lower than the minimum air conditioning capacity Th1min indicated by the air conditioning function capacity information 711, the control unit 101 determines that the power consumption per air conditioning capacity Only the air conditioner 2E_2 smaller than the air conditioner 2E_1 is caused to process the heat load target value (example of the first heat load) ACL. With this control, air conditioning control can be realized in a state of high energy efficiency using a lower capacity than that of the air conditioner 2E_1.

If minimum air conditioning capacity Th1min of air conditioner 2E_1<heat load target value (example of first heat load) ACL<maximum air conditioning capacity Th2max of air conditioner 2E_2, control unit 701 controls air conditioner 2E_1 and air conditioner A control signal is output so that processing is performed using the air conditioning capacity of the air conditioner 2E_2 with the smaller power consumption among the air conditioners 2E_2.

When the maximum air conditioning capacity Th2max of the air conditioner 2E_2<the target heat load value (example of the first heat load) ACL<the maximum air conditioning capacity Th1max of the air conditioner 2E_1, the control unit 701 controls the air conditioning capacity of the air conditioner 2E_1. output a control signal to process using

Then, when the maximum air conditioning capacity Th1max of the air conditioner 2E_1<the heat load target value (example of the first heat load) ACL, the control unit 701 performs processing using the air conditioning capacities of the air conditioners 2E_1 and 2E_2. Output a control signal.

(Seventh embodiment)
In the above-described embodiment, the case where the heat load is shared by the air conditioner and the ventilation device has been described. A latent heat/sensible heat separation operation in which temperature treatment is performed in a machine may be performed.

It is assumed that the configuration of this embodiment has the same configuration as the configuration shown in FIG. However, the control unit 101 differs in the processing it performs in adjusting the temperature and humidity.

The air supply unit 20 according to the present embodiment functions as an evaporator and removes moisture by condensing moisture in the air when exchanging heat with the taken air. In this way, the air supply unit 20 is configured as a device capable of reducing the evaporation temperature of the refrigerant by condensation.

When the air conditioner 2 receives the target temperature and the target humidity of the living room space R11 from a remote controller or the like, it notifies the host controller 100 of the target temperature and the target humidity. Thereby, the target temperature and the target humidity are set in the host controller 100 .

Then, the control unit 101 of the host controller 100 calculates the target heat load value ACL using the same method as in the above-described embodiment. When the target heat load value ACL is the cooling load, a control signal is output to cause the first heat exchanger 22 of the air supply unit 20 of the ventilator 1 to function as an evaporator.

Then, when the first heat exchanger 22 functions as an evaporator, the control unit 101 of the host controller 100 controls the flow of air in a state where the first heat exchanger 22 is condensed (a state in which the evaporation temperature is reduced). The ventilation system 1 is controlled so as to achieve the target humidity by dehumidifying the humidity.

Furthermore, the control unit 101 of the host controller 100 controls the air conditioner 2 to reach the target temperature by performing temperature control on the air conditioner 2 so as to achieve the target temperature.

FIG. 19 is a psychrometric diagram illustrating the transition until the target temperature and target humidity are reached by the control of the ventilator 1 and the air conditioner 2 according to this embodiment.

Point 3501 shown in FIG. 19 is the temperature and humidity of the air taken in from the outdoors, and point 3504 is the target temperature and target humidity.

Control section 101 outputs a control signal to air supply unit 20 . As a result, the air supply unit 20 causes the first heat exchanger 22 to function as an evaporator, thereby lowering the temperature of the taken air as indicated by the line 3511, and then, as indicated by the line 3512, The temperature and humidity are controlled to decrease along the 100% humidity curve. This allows the humidity to reach the target humidity. In other words, the humidity (target humidity) and temperature indicated by point 3503 are reached by the control of the air supply unit 20 .

Therefore, the control unit 101 outputs to the ventilator 1 a control signal that causes the first heat exchanger 22 to function so that the temperature corresponding to the target humidity on the 100% relative humidity curve in the psychrometric diagram is obtained. . That is, in the present embodiment, the control unit 101 controls that the air supplied from the air supply unit 20 after heat is exchanged in the second heat exchanger reaches the target humidity along the curve of 100% relative humidity in the air diagram. The amount of dehumidification can be maintained and controlled by controlling to maintain the corresponding temperature.

After that, the controller 101 outputs a control signal to the air conditioner 2 . As a result, the air conditioner 2 raises the temperature of the air from the humidity (target humidity) and temperature indicated by point 3503 as indicated by line 3513 to the temperature (target temperature) and humidity (target humidity) indicated by point 3504 . humidity).

In this embodiment, the ventilator 1 processes the latent heat load and the air conditioner 2 processes the sensible heat load, so that the temperature and humidity can be controlled with high accuracy. This control can improve power consumption efficiency.

(Eighth embodiment)
In the eighth embodiment, a method for adjusting humidity in the air supply unit will be described. The adjustment of humidity may be combined with, for example, the method of adjusting humidity described in the fourth embodiment.

It is assumed that the configuration of this embodiment has the same configuration as the configuration shown in FIG. However, the control unit 101 differs in the processing it performs in adjusting the temperature and humidity.

The air supply unit 20 according to the present embodiment humidifies the air after heat has been exchanged in the first heat exchanger 22 by supplying water.

When the air conditioner 2 receives the target temperature and the target humidity of the living room space R11 from a remote controller or the like, it notifies the host controller 100 of the target temperature and the target humidity. Thereby, the target temperature and the target humidity are set in the host controller 100 .

Then, the control unit 101 of the host controller 100 calculates the target heat load value ACL using the same method as in the above-described embodiment. When the heat load target value ACL is the heating load, a control signal is output to cause the first heat exchanger 22 of the air supply unit 20 of the ventilator 1 to function as a condenser.

In this embodiment, when the heat load target value ACL is shared between the air conditioner 2 and the ventilation device 1, the ventilation device 1 is in charge of the heat load corresponding to the amount of air supplied at the target temperature and the target humidity. 2 is responsible for the difference between the heat load target value ACL and the heat load corresponding to the supply air.

When the ventilator 1 performs the humidification operation, the control unit 101 of the host controller 100 controls the target temperature and the target humidity when water is supplied to the air that has been heat-exchanged by the first heat exchanger 22. A control signal is output to the air supply unit 20 to set the temperature of the air after heat exchange by the first heat exchanger and perform temperature control based on the setting.

FIG. 20 is a psychrometric diagram illustrating the transition until the target temperature and target humidity are reached by the control of the ventilator 1 and the air conditioner 2 according to this embodiment.

Point 3401 shown in FIG. 20 is the temperature and humidity of the air taken in from the outdoors, and point 343403 is the target temperature and target humidity.

Control section 101 outputs a control signal to air supply unit 20 . As a result, the air supply unit 20 causes the first heat exchanger 22 to function as a condenser, thereby raising the temperature of the taken air as indicated by line 3411 . This reaches the humidity and temperature indicated by point 3402 .

After that, the air supply unit 20 supplies water to the heat-exchanged air. This reaches the humidity (target humidity) and temperature (target temperature) indicated by point 3403 by isenthalpic change as indicated by line 3412 .

In this way, when the ventilator 1 performs the humidification operation, the control unit 101 controls the preset target The temperature of the air after being heat-exchanged by the first heat exchanger is set so as to achieve the temperature and target humidity, and a control signal is output to the air supply unit 20 to control the temperature based on the setting.

In the present embodiment, considering that the temperature decreases with humidification due to isenthalpy, the first heat exchanger 22 performs heat exchange, thereby realizing efficient humidity control and temperature control.

(Ninth embodiment)
FIG. 21 is a diagram illustrating configurations of a host controller 1200, an air supply unit 1220, an exhaust unit 1210, and a compressor unit 1250 according to this embodiment. In addition, the same code|symbol is assigned about the structure similar to embodiment mentioned above, and description is abbreviate|omitted.

Note that the host controller 1200 also controls an air conditioner (not shown). The coordinated control of the air conditioner and the ventilator including the air supply unit 1220 and the exhaust unit 1210 by the host controller 1200 is used, for example, during the heat recovery ventilation operation, and the explanation is omitted as it is the same as the above-described embodiment.

The air supply unit 1220 forms an air flow path from the outdoors to the living room space, and has at least the fan 21 , the first heat exchanger 22 and the straightening fins 1290 .

The exhaust unit 1210 forms an air flow path from the living room space to the outdoors, and has the fan 11 and the second heat exchanger 12 .

The host controller 1200 performs the same processing as in the above-described embodiment, so that the heat load target value ACL (first heat load example ). When the host controller 1200 determines that the heat load target value ACL is the cooling load, the host controller 1200 performs the following processing.

When the outdoor air temperature detected by the temperature detection unit 24 of the air supply unit 20 is lower than the target temperature set in the living room space R11, the host controller 1200 operates the compressor included in the compressor unit 50. is suppressed, and the ventilation device 1 exchanges the air in the living room space R11 with the outdoor air. set one.

In this embodiment, host controller 1200 adjusts rectifying fins 1290 provided in air supply unit 1220 downward.

Furthermore, the host controller 1200 sets the amount of air supplied from the air supply unit 1220 to the maximum value that can be set (sets the fan 21 to the maximum rotation speed), and takes in and exhausts air from the exhaust unit 1210. is set to the maximum possible value (the fan 11 is set to the maximum rotation speed).

By this control, the host controller 1200 switches the air flow 2611 when the wind direction and air volume are not adjusted to the air flow 2602 when the wind direction and air volume are not adjusted.

For example, early in the morning in summer, the outside air temperature may be lower than the target temperature of the living room space. In this case, the relationship of outside air temperature<indoor target temperature<indoor temperature is established.

In such a case, the host controller 1200 stops the temperature control of the air supply unit 1220 and the exhaust unit 1210 (suppresses the driving of the compressor), actively takes in the outside air, and adjusts the indoor temperature to the target temperature. can be controlled to

In this case, the host controller 1200 adjusts the airflow direction and airflow rate to improve the ventilation efficiency and to quickly reach the target temperature with low power consumption.

(Modification of the ninth embodiment)
The temperature adjustment method using outside air is not limited to the method shown in the ninth embodiment. For example, when there are a plurality of air supply ports and exhaust ports, it is conceivable to adjust the temperature by controlling air circulation in the living room space.

For example, as shown in FIG. 13, the four air supply ports 392A to 392D, which are the air supply destinations of the air supply unit 320, are located below the air conditioning indoor units 381, 382, and 383 in FIG. The four exhaust ports 391A to 391D, which are the air intake ports of the exhaust unit 310, are located above the air conditioning indoor units 381, 382, and 383 in FIG. provided on the second direction side in the room space).

The four air supply ports 392A to 392D incorporate a fan (an example of a first air volume adjustment mechanism) that adjusts the amount of air supplied to each air supply port. The fan is controlled by the host controller 300 .

Each of the four exhaust ports 391A to 391D incorporates an open/close damper (an example of a second air volume adjustment mechanism) that adjusts the amount of air taken in by each exhaust port. The opening/closing damper is controlled by the host controller 300 .

Then, the host controller 300 as shown in FIG. 13 performs the same processing as in the above-described embodiment, so that the heat load target determined as the control target in the living room space R11 based on the temperature of the living room space R11, etc. Calculate the value (example of the first heat load) ACL. When the host controller 300 determines that the heat load target value ACL is the cooling load, the host controller 300 performs the following processing.

When the outdoor air temperature detected by the temperature detection unit 24 of the air supply unit 20 is lower than the target temperature set in the living room space R11, the host controller 300 operates the compressor included in the compressor unit 50. is controlled so that air is supplied from all the air supply ports 392A to 392D arranged on the south side of the living room space and exhausted from all the air outlets 391A to 391D arranged on the north side of the living room space. Also, rectifying fins may be provided in the air supply ports 392A to 392D, and combined with the same control as in the ninth embodiment.

In this embodiment, the ventilation efficiency is improved, and the target temperature can be reached quickly.

(Tenth embodiment)
Another mode of processing in the host controller will be described. It is assumed that the ventilator and the air conditioner have the same configuration as in the embodiment described above.

FIG. 22 is a diagram illustrating the configuration of the host controller 1100 according to this embodiment. As shown in FIG. 22, a host controller 1100 (an example of an air conditioning control device) includes an air conditioning load acquisition unit 1101, an operating instruction plan generation unit 1102, a situation calculation unit 1203, a storage unit 1204, and an operation plan extraction unit. and a part 1205 .

The air-conditioning load acquisition unit 1101 acquires the heat load target value ACL in the same procedure as in the embodiment described above.

Based on the target heat load value ACL, the operating instruction proposal generating unit 1102 generates a plurality of operating instructions for controlling the air conditioner and the ventilation device in order to control the air conditioning of the indoor space in which the air conditioner and the ventilation device are installed. Generate a draft instruction (an example of driving instruction information).

In this embodiment, the host controller 1100 holds in advance a learned model obtained by machine-learning the target heat load value ACL and the operation behavior of the air conditioner and the ventilator.

Then, the host controller 1100 inputs the heat load target value ACL to generate a plurality of operation instruction proposals for the air conditioner and the ventilator.

The situation calculation unit 1203 acquires the amount correlated with the air conditioning load of the indoor space, and considers the amount correlated with the air conditioning load of the indoor space for each generated operating instruction proposal, and issues an operation instruction for the air conditioning load of the indoor space. Calculate the amount of energy when processed according to the plan. Any known technique may be used as the method for calculating the amount of energy.

The amount correlated with the indoor air conditioning load includes the amount related to the amount of air ventilated by the ventilator.

The storage unit 1204 stores the correspondence relationship between the driving instruction plan and the calculated energy amount.

The driving plan extracting unit 1205 outputs to at least one of the air conditioner and the ventilator a driving instruction based on the driving instruction plan associated with the amount of energy that satisfies a predetermined condition. At this time, the driving plan extracting unit 1205 selects the plan with the least energy consumption from among the driving instruction plans associated with the energy amounts that satisfy a predetermined condition.

The predetermined condition is, for example, when the total heat balance of the indoor space is a temperature rise, cold heat is recovered from the exhaust gas (high-temperature refrigerant flows through the exhaust route heat exchanger), and the total heat balance of the indoor space is a temperature drop. In some cases, the conditions are such that thermal heat can be recovered from waste heat.

In other words, when the air conditioner and the ventilation device are linked, if the heat balance in the living room space is rising, the cold heat is recovered in the exhaust unit (high temperature refrigerant is flowed, cooling operation is performed), and the air conditioner But I will run the air conditioner. In addition, when the heat balance in the room space is low, the condition is set so that the heat is recovered in the exhaust unit (heating operation) and the air conditioner also performs the heating operation.

In other words, the energy efficiency can be improved by aligning the heating and cooling of the temperature control of the air conditioner and the ventilator.

(Eleventh embodiment)
In the above-described embodiment, the air supply unit and the exhaust unit are installed in the space above the ceiling in order for the ventilation device to perform ventilation, and the air supply port connected to the air supply unit and the exhaust port connected to the exhaust unit is provided on the ceiling of the living room space. However, the embodiments described above are not limited to this arrangement. Therefore, in the eleventh embodiment, an example in which an air supply unit and an exhaust unit are arranged in a living room space will be described.

FIG. 23 is a diagram showing a configuration example of a ventilation device, an air conditioner, and a host controller according to the eleventh embodiment. In the example shown in FIG. 23, the air conditioning system includes a ventilator 1G, an air conditioner 2, and a host controller 100 for air conditioning the indoor space.

The air supply unit 1320 passes outside air (OA) taken in from the outdoors through the control unit 23, the first heat exchanger 22, and the first heat exchanger 22, and then supplies the air (SA) to the living room space R11. It has a structure (example of a first casing) housing a fan 21 (example of a first air volume adjustment mechanism).

The exhaust unit 1310 is a fan that exhausts (EA) the air that has been returned (RA) from the control unit 13, the second heat exchanger 12, and the living room space R11 to the outdoors after passing it through the second heat exchanger 12. 11 (an example of a second air volume adjustment mechanism) and a structure (an example of a second casing) that accommodates them.

The exhaust unit 1310 and the air supply unit 1320 according to this embodiment are installed in the living room space R11. In this embodiment, the exhaust unit 1310 and the air supply unit 1320 are installed at different heights.

In the example shown in FIG. 23, the control unit 101 causes the first heat exchanger 22 to function as a condenser and the second heat exchanger 12 to function as an evaporator for the ventilator 1G.

Therefore, in the air supply unit 1320, after the outside air (OA) taken in is warmed, the air (SA) is supplied to the living room space R11. The air supply unit 1320 heats the living room space R11 from the vicinity of the floor with the heated air (SA). Since the supplied air (SA) is warm, it rises in the living room space R11.

The exhaust unit 1310 functions to take in return air (RA) from the room space R11 and exhaust it to the outside (EA). Since the exhaust unit 1310 is provided in the vicinity of the ceiling, the warmed supply air (SA) is used to return (RA) the air that has risen from the vicinity of the floor. can be practically realized. Furthermore, in this embodiment, since an airflow circulating in the height direction can be formed, control can be performed so that the temperature distribution in the living room space R11 is substantially uniform.

This embodiment may be combined with each configuration of the above-described embodiments. For example, a plurality of exhaust units 1310 and air supply units 1320 may be provided.

(Modification of the eleventh embodiment)
In the eleventh embodiment, an example in which the exhaust unit 1310 is installed near the ceiling and the air supply unit 1320 is installed near the floor has been described. However, the eleventh embodiment shows an example of the arrangement, and a different arrangement may be used as long as the heights of the exhaust unit and the air supply unit are different.

FIG. 24 is a diagram showing a configuration example of a ventilation device, an air conditioner, and a host controller according to a modification of the eleventh embodiment. In the example shown in FIG. 24, the air conditioning system includes a ventilator 1H, an air conditioner 2, and a host controller 100 for air conditioning the living room space R11. In this embodiment, the same reference numerals are assigned to the same configurations as in the above-described embodiment, and the description thereof is omitted.

The ventilator 1H includes a compressor unit 50, an exhaust unit 1410, an air supply unit 1420, a compressor unit 50, and refrigerant circuits F1, F2, F3, and F4.

The exhaust unit 1410 and the air supply unit 1420 according to this embodiment are installed in the living room space R11. In this embodiment, as in the eleventh embodiment, the exhaust unit 1410 and the air supply unit 1420 are installed at different heights.

In the example shown in FIG. 24, the exhaust unit 1410 is installed near the floor, and the air supply unit 1420 is installed near the ceiling. Further, the exhaust unit 1410 is provided near the right wall of the living room space R11, and the air supply unit 1420 is provided near the left wall of the living room space R11. This modification shows an example of the arrangement, and the exhaust unit 1410 and the air supply unit 1420 may be provided in the vicinity of opposing walls.

In the example shown in FIG. 24, the control unit 101 causes the first heat exchanger 22 to function as an evaporator and the second heat exchanger 12 to function as a condenser with respect to the ventilator 1H.

Therefore, the air supply unit 1420 cools the taken outside air (OA), and then supplies the air (SA) to the living room space R11. In this modified example, the living room space R11 is cooled from the vicinity of the ceiling by cooled air supply (SA) from the air supply unit 1420 . Since the supplied air (SA) is cold, it descends through the living room space R11.

The exhaust unit 1410 functions to take in return air (RA) from the living room space R11 and exhaust it to the outside (EA). Since the exhaust unit 1410 is provided near the floor, it takes in the return air (RA) that has descended from the vicinity of the ceiling with the cooled supply air (SA), so that the air circulation in the living room space R11 is efficiently performed. can be realized. Furthermore, in this embodiment, since an airflow circulating in the height direction can be formed, control can be performed so that the temperature distribution in the living room space R11 is substantially uniform.

The above-described eleventh embodiment and its modification are examples of the arrangement of the exhaust unit and the air supply unit. good. This embodiment may be combined with each configuration of the above-described embodiments. For example, a plurality of exhaust units and air supply units may be provided.

(Twelfth embodiment)
The above-described embodiment shows an example of the air supply unit and the exhaust unit of the ventilator, and the air supply unit and the exhaust unit may be in other forms. Therefore, in the twelfth embodiment, an example in which the air supply unit and the exhaust unit are different from the above-described embodiments will be described.

FIG. 25 is a diagram showing a configuration example of a ventilation device, an air conditioner, and a host controller according to the twelfth embodiment. In the example shown in FIG. 25, the air conditioning system includes a ventilator 1I, an air conditioner 2, and a host controller 1600 for air conditioning the living room space R11. In this embodiment, the same reference numerals are assigned to the same configurations as in the above-described embodiment, and the description thereof is omitted.

The air conditioner 2 includes an outdoor unit 70 and two air conditioner indoor units 81 and 82, as in the first embodiment.

The host controller 1600 performs the same control (for example, heat load sharing control) as the host controller of the above-described embodiment. and a control unit 1601 for performing the following control.

The ventilator 1I includes a compressor unit 50, an exhaust unit 1610, an air supply unit 1620, a compressor unit 50, and refrigerant circuits F1, F2, F3, and F4.

The air supply unit 1620 has an air supply damper (an example of a first switching mechanism) 1625 capable of switching the intake of air between the outdoors and the living room space R11, the first heat exchanger 22, and the air supply damper 1625. A structure (first casing example).

The exhaust unit 1610 includes an exhaust damper (an example of a second switching mechanism) 1615 capable of switching the air output destination between the outdoors and the living room space R11, the second heat exchanger 12, and the air taken in from the living room space R11.

In the example shown in FIG. 25, the control unit 1601 causes the first heat exchanger 22 to function as a condenser and the second heat exchanger 12 to function as an evaporator for the ventilator 1I.

In the example shown in FIG. 25, the supply air damper 1625 is switched to take in outside air (OA) from the outdoors, and the exhaust damper 1615 exhausts (EA) the taken return air (RA). It is in a switched state.

By the way, when the difference between the temperature of the living room space R11 and the outdoor temperature is large, the outside air is warmed to the same temperature as the air of the living room space R11 when performing ventilation as shown in FIG. requires a lot of energy. On the other hand, when there are not many people in the living room space R11, the CO2 concentration is low, so it can be regarded as a situation where active ventilation is not required. In other words, there are situations in which the ventilation capacity may be reduced.

Therefore, the control unit 1601 of this embodiment performs control to switch between the exhaust damper 1615 and the supply air damper 1625 according to the outdoor environment and the indoor environment of the living room space R11.

FIG. 26 is a diagram showing a switching example of the air supply damper 1625 and the exhaust damper 1615 according to this embodiment. In the example shown in FIG. 26, the supply air damper 1625 switches the air intake destination to the outdoors, and the exhaust damper 1615 controls the air output destination to switch to the living room space R11.

As the first environmental condition, for example, the CO2 concentration detected by a sensor (not shown) is lower than the first concentration, and the difference between the temperature of the living room space R11 and the outdoor temperature is higher than the first temperature difference. And if you meet high things. The first concentration is assumed to be the CO2 concentration determined as a criterion for when there is no person in the living room space R11. The first temperature difference is a temperature difference that serves as a criterion for determining whether or not energy saving measures should be taken, and is determined according to the embodiment.

In the example shown in FIG. 26, the output destination of the air from the exhaust damper 1615 is switched to the living room space R11 while suppressing an increase in the CO2 concentration by referring to the detection result of the sensor unit (not shown). Therefore, the discharge of warm air to the outside is suppressed. Thereby, the air-conditioning system which concerns on this embodiment can implement|achieve energy saving.

FIG. 27 is a diagram showing a switching example of the air supply damper 1625 and the exhaust damper 1615 according to this embodiment. In the example shown in FIG. 27, the supply air damper 1625 switches the air intake destination to the living room space R11, and the exhaust damper 1615 switches the air output destination to the living room space R11.

The control unit 1601 performs switching control as shown in FIG. 26 when the second environmental condition is satisfied. As the predetermined condition, for example, the CO2 concentration is lower than the first concentration, and the difference between the temperature of the living room space R11 and the outdoor temperature is higher than the second temperature difference (second temperature difference>first temperature difference). If you meet the following conditions: The second temperature difference is a temperature difference that serves as a criterion for determining whether or not energy saving measures should be taken, and is a larger value than the first temperature difference, and is determined according to the embodiment.

In the example shown in FIG. 27, by referring to the detection result of the sensor unit (not shown), the air supply damper 1625 can switch the air intake destination to the living room space R11 while suppressing an increase in the CO2 concentration. In addition, since the air output destination of the exhaust damper 1615 is switched to the living room space R11, a decrease in the temperature of the living room space R11 can be suppressed. Compared to the switching situation shown in FIG. 26, the switching situation shown in FIG. 27 does not require the outside air to rise to the temperature of the living room space R11, so further energy saving can be achieved.

25 to 27 are examples of switching each of the supply air damper 1625 and the exhaust air damper 1615 on and off, in other words, switching between ventilation and indoor circulation. In this embodiment, ventilation and indoor circulation may be used in combination.

FIG. 28 is a diagram showing a switching example of the air supply damper 1625 and the exhaust damper 1615 according to this embodiment. In the example shown in FIG. 28, switching control is performed so that the supply air damper 1625 uses both the living room space R11 and the outdoors as the air intake destination, and the exhaust damper 1615 uses both the living room space R11 and the outdoors as the air output destination. is being done.

The control unit 1601 performs switching control as shown in FIG. 26 when the third environmental condition is satisfied. As the third environmental condition, for example, the CO2 concentration is lower than the second concentration (second concentration > first concentration), and the difference between the temperature of the living room space R11 and the outdoor temperature is higher than the second temperature difference. If you meet the following conditions: The second concentration is, for example, the CO2 concentration determined as a criterion for the presence of only a few people in the living room space R11.

(14th embodiment)
In the above-described fourth embodiment, an example of a method for adjusting humidity has been described. However, alternative modes for adjusting humidity may be used. Therefore, in the fourteenth embodiment, an example in which the amount of humidification is distributed to each area will be described.

This embodiment is assumed to have a configuration similar to that of FIG. Then, the host controller 100 acquires the required amount of humidification in the living room space R101. The amount of humidification required in the living room space R101 (hereinafter referred to as the target amount of humidification) may be obtained by a conventional method, and may be calculated according to the target humidity input by the user, for example.

Then, the host controller 100 acquires the temperature of the air in the region R101A (an example of the first region) and acquires the temperature of the air in the region R101B (an example of the second region). A well-known method may be used as a method for acquiring air in the region R101A (an example of the first region) and the region R101B (an example of the second region). (an example of two areas) is obtained from a sensor unit (not shown) provided in each of the two areas.
