As a result, in the first operation step S25, as shown in FIG. 2, the first indoor air conditioner 11 and the second indoor air conditioner 12 start the instructed air conditioning operation (heating operation or cooling operation). In the first operation step S25 of the present embodiment, both the first indoor air conditioner 11 and the second indoor air conditioner 12 are heated during heating. On the other hand, during cooling, both the first indoor air conditioner 11 and the second indoor air conditioner 12 are operated for cooling.

When the first indoor air conditioner 11 and the second indoor air conditioner 12 have 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. NS. Further, the set temperatures of the first indoor air conditioner 11 and the second indoor air conditioner 12 are set, for example, in order to supply effective air for air conditioning of each living room 7 (in this example, the living rooms 7a and 7b on the first floor). It is appropriately set based on the above-mentioned target temperature.

As shown in FIG. 3, in the first operation step S25 of the present embodiment, information for the calculation unit 31 to operate the first fan 14 and the second fan 27 with a predetermined air volume is transmitted, respectively. NS. If the first fan 14 and the second fan 27 are stopped in the first operation step S25, these operations are started. As a result, in the first operation step S25, while circulating the air A5 in the building 2 shown in FIG. 1, the underfloor air A4 (outside air A3) is supplied into the chamber 10, and the air A6 (air conditioning) in the chamber 10 is supplied. Air (including air A1 and A2) can be supplied to each living room 7. Therefore, it is possible to ventilate and air-condition a plurality of living rooms 7 in the building 2.

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 and the air volume of the second fan 27 are 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.

In the first operation step S25 of the present embodiment, as shown in FIG. 2, the calculation unit 31 (shown in FIG. 3) uses the wind direction adjusting means 21 of the second indoor air conditioner 12 to the second indoor air conditioner 12. A signal for adjusting the wind direction of the conditioned air A2 is transmitted so that the conditioned air A2 is supplied to the suction port 11a of the first indoor air conditioner 11.

In the first operation step S25, the conditioned air A2 of the second indoor air conditioner 12 is sucked into the first indoor air conditioner 11. The temperature of the 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 conditioned) in the building 2 taken in from the air introduction port 20. Therefore, in the first operation step S25, the conditioned air A2 of the second indoor air conditioner 12 is sucked by the first indoor air conditioner 11 to exchange heat, so that each living room 7 (in this example, the living room 7a on the first floor) is exchanged. , 7b) The 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 conditioned air A1 to each living room 7, it is possible to achieve the temperature of each living room 7 at an early stage to the set temperature of 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.

In the first operation step S25, the larger the negative degree of the temperature of each room 7 (in this example, the rooms 7a and 7b on the first floor), the higher the set temperature of the first room air conditioner 11 and the second room air conditioner 12. , The temperature may be set to an effective temperature by the air conditioning of each living room 7. In addition, "the negative degree of the temperature of the living room 7 is large" means that the temperature of each living room 7 deviates from the target temperature in a disadvantageous direction to a large extent. Further, "setting a temperature effective for air conditioning of each living room 7" means that the set temperatures of the first indoor air conditioner 11 and the second indoor air conditioner 12 are set to relatively high temperatures during the heating operation. It means that. On the other hand, during the cooling operation, it means that the set temperatures of the first indoor air conditioner 11 and the second indoor air conditioner 12 are set to relatively low temperatures. As a result, the larger the negative degree of the temperature of each living room 7, the more effective air (air-conditioned air A1) for air conditioning of each living room 7 can be discharged from the first indoor air conditioner 11 in a shorter time. Become.
