Next, the processing procedure of the air conditioning method of the present embodiment will be described. FIG. 3 is a flowchart showing an example of the processing procedure of the air conditioning method of the building 2. This processing procedure is carried out based on the control procedure stored in the control device 15 (shown in FIG. 1).

In the air conditioning method of the present embodiment, it is first determined whether or not there is an instruction to start the air conditioning operation by the whole building air conditioning system 1 (process S1). The determination as to whether or not there is an instruction to start the air conditioning operation is performed, for example, based on the instruction information regarding the start of the air conditioning operation (heating operation or cooling operation) input by the resident or the like to the input means (not shown).

As shown in FIG. 3, when it is determined in step S1 that there is an instruction to start air conditioning operation (“Y” in step S1), the next air conditioning step S2 is carried out. On the other hand, when it is determined in step S1 that there is no instruction to start air conditioning operation (for example, there is an instruction to stop air conditioning operation) (“N” in step S1), an instruction to end air conditioning control by the entire building air conditioning system 1 Step S3 for determining whether or not there is is carried out.

Next, in the air conditioning step S2 of the present embodiment, as shown in FIG. 1, a plurality of living rooms 7 (in this example, 1) are used by using at least one of the first indoor air conditioner 11 and the second indoor air conditioner 12. The living rooms 7a and 7b) on the floor are air-conditioned. In the air-conditioning step S2 of the present embodiment, each living room 7 (living rooms 7a, 7b on the first floor) is air-conditioned based on a predetermined target temperature.

The target temperature can be set as appropriate. In the present embodiment, a preset temperature set in each living room 7 (in this example, living rooms 7a and 7b on the first floor) is set as a target temperature. When the set temperature is set for each living room 7 (living rooms 7a and 7b on the first floor) as in the present embodiment, the highest set temperature among those set temperatures is the target temperature during the heating operation. It is desirable to be defined as. On the other hand, during the cooling operation, it is desirable that the lowest set temperature among those set temperatures is set as the target temperature. As a result, in the air conditioning step S2, air effective for air conditioning of all the living rooms 7 (living rooms 7a and 7b on the first floor) can be supplied from the first heat source 9A and / or the second heat source 9B.

In the present specification, the air effective for air conditioning is air having a temperature higher than the target temperature during the heating operation. On the other hand, in the cooling operation, the air effective for air conditioning is air having a temperature lower than the target temperature.

In the air conditioning step S2 of the present embodiment, first, a first operation step of operating only one of the first indoor air conditioner 11 and the second indoor air conditioner 12 is carried out (first operation mode). FIG. 4 is a conceptual diagram showing an example of the first operation mode.

In the first operation process of the present embodiment, only the first indoor air conditioner 11 is operated (first operation mode). In the first operation step, first, the control device 15 (shown in FIG. 1) causes the first indoor air conditioner 11 to perform a heating operation or a cooling operation based on the instruction information regarding the start of the air conditioning operation (heating operation or cooling operation). Transmits a signal to initiate. As a result, in the air conditioning step S2, the first indoor air conditioner 11 starts the instructed air conditioning operation (heating operation or cooling operation).

When the first indoor air conditioner 11 has already executed the instructed air conditioning operation (heating operation or cooling operation), the transmission of the signal for starting the air conditioning operation is omitted. Further, the set temperature of the first indoor air conditioner 11 is appropriately set based on, for example, a target temperature in order to supply air effective for air conditioning of a plurality of living rooms 7 (in this example, living rooms 7a and 7b on the first floor). Set.

In the first operation step of the present embodiment, information for operating the control device 15 (shown in FIG. 1) to the first fan 14 and the second fan 27 with a predetermined air volume is transmitted, respectively. If the first fan 14 and the second fan 27 are stopped in the first operation step, these operations are started. As a result, in the first operation step (first operation mode), the underfloor air A4 (outside air A3) is supplied into the chamber 10 while the air A5 in the building 2 is circulated, and the air A6 (air conditioning) in the chamber 10 is supplied. (Including air A1) can be supplied to each living room 7 (living rooms 7a and 7b on the first floor). Therefore, in the first operation step (first operation mode), the plurality of living rooms 7 in the building 2 can be ventilated and air-conditioned.

The air volume of the first fan 14 and the air volume of the second fan 27 are appropriately set. It is desirable that the air volume of the first fan 14 is set based on, for example, the air volume of the first indoor air conditioner 11 (air-conditioned air A1). On the other hand, it is desirable that the air volume of the second fan 27 is set based on, for example, the ventilation frequency required for the building 2. In the present specification, when the "air volume of the first fan 14" is composed of a plurality of first fans 14, it is specified as the total air volume of those first fans 14. Further, the air volume of the second fan 27 is specified in the same manner as that of the first fan 14.

Next, in the air conditioning process S2 of the present embodiment, as shown in FIG. 2, the operation of the second indoor air conditioner 12 is started, so that both the first indoor air conditioner 11 and the second indoor air conditioner 12 are used. The second operation step to operate is carried out (second operation mode).

In the present embodiment, the operation of the second indoor air conditioner 12 is started by the operation of a resident or the like. Therefore, in the air conditioning process S2 of the present embodiment, the first operation process (first operation mode) and the second operation process (second operation mode) are switched at the discretion of the resident or the like. Further, the set temperature of the second indoor air conditioner 12 is appropriately selected by a resident or the like.

In the second operation step (second operation mode), the air conditioned by the second indoor air conditioner 12 (air-conditioned air A2) is supplied to the first indoor air conditioner 11 via the air introduction port 20. The temperature of the air-conditioned air A2 of the second indoor air conditioner 12 is closer to the target temperature than the temperature of the air A5 (air before being air-conditioned) in the building 2. As a result, in the present embodiment, the air-conditioned air A2 of the second indoor air conditioner 12 is sucked by the first indoor air conditioner 11 to exchange heat, so that the plurality of living rooms 7 (living rooms 7a and 7b on the first floor) are connected. Air effective for air conditioning (air conditioning air A1) can be discharged from the first indoor air conditioner 11 in a short time. By supplying such air-conditioned air A1 to the plurality of living rooms 7, the temperature of each living room 7 can be achieved at an early stage to the temperature set in each living room 7. Therefore, the whole building air conditioning system 1 of the present embodiment can improve the comfort of each living room 7.

The second operation step (second operation mode) of the present embodiment is carried out, for example, at the start of the air conditioning operation by the whole building air conditioning system 1 or when the temperature of at least one living room 7 is negative with respect to the target temperature. Is desirable. In the present specification, the negative means that the temperature of each living room 7 (shown in FIG. 1) deviates in a disadvantageous direction with respect to the target temperature. For example, when the temperature of each living room 7 is lower than the target temperature during the heating operation (room temperature <target temperature), it is determined to be negative. On the other hand, when the temperature of each room 7 is higher than the target temperature during the cooling operation (room temperature> target temperature), it is determined to be negative. Such a determination as to whether or not it is negative may be made by the control device 15, or may be made by a resident or the like. The temperature of each living room 7 can be obtained from, for example, a measurement result of a temperature sensor (not shown) installed in each living room 7. Further, when the above determination is made by the control device 15, it is desirable that a message or the like indicating negative is displayed on the output means (not shown).

In the second operation step (second operation mode), it is desirable that the wind direction adjusting means 21 is adjusted so that the wind direction of the conditioned air A2 of the second indoor air conditioner 12 is directed to the air introduction port 20. As a result, in the second operation step, the distance until the conditioned air A2 reaches the air introduction port 20 can be shortened, so that the temperature change of the conditioned air A2 supplied to the first indoor air conditioner 11 is reduced. be able to. Therefore, in the second operation step, it is possible to achieve the temperature of each living room 7 at an early stage to the temperature set in each living room 7 (in this example, the living rooms 7a and 7b on the first floor).

In the second operation step (second operation mode), the non-living room 8 (hall 8a) to which the air A5 circulating in the living room 7 (in this example, the living rooms 7a and 7b on the first floor) is supplied can be air-conditioned. Therefore, the air conditioning method of the present embodiment (whole building air conditioning system 1) can effectively prevent heat shock in the non-living room 8 (hall 8a).

In the second operation step (second operation mode), for example, when the temperatures of all the living rooms 7 (in this example, the living rooms 7a and 7b on the first floor) are no longer negative with respect to the target temperature (when they become positive). ), It is switched to the first operation process (first operation mode) shown in FIG.
