Document Type and Number:
Japanese Patent JP2020186820
Kind Code:
A
Abstract:
To provide an air conditioning system enabling ventilation for a short time when a refrigerant is leaked from an air conditioner.SOLUTION: An air conditioning system 10 includes an air conditioner 11, a refrigerant sensor 26, a ventilation device 12 and a controller. The ventilation device 12 includes: a total heat exchanger 32; a first supply air path 47 and a first exhaust air path 46 that communicate inside and outside of an air-conditioned space via the total heat exchanger 32; a second supply air path 48 that communicates inside and outside of the air-conditioned space without interposing the total heat exchanger 32; an air supply fan 34 supplying air outside the air-conditioned space into the air-conditioned space via the first supply air path 47 and the second supply air path 48; an air exhaust fan 33 discharging the air in the air-conditioned space to outside of the air-conditioned space via the first exhaust air path 46; and an air supply opening/closing mechanism 55 opening/closing the first supply air path 47 and the second supply air path 48 in a switching manner. The controller 36 controls the air supply opening/closing mechanism 55 so as to open the second supply air path 48 when the refrigerant sensor 26 detects leakage of a refrigerant.SELECTED DRAWING: Figure 6
