Title:
AIR CONDITIONING DEVICE
Document Type and Number:
Japanese Patent JP2022115492
Kind Code:
A
Abstract:
To provide an air conditioning device capable of suppressing impact shock by a refrigerant transmitted to an opening/closing device for opening and closing refrigerant piping.SOLUTION: An air conditioning device includes: an outdoor unit 20 provided with a compressor 21; an indoor unit in which a utilization-side heat exchanger is housed; a refrigeration circuit formed by connecting the compressor 21 and the utilization-side heat exchanger by refrigerant piping so that a refrigerant is circulated therein; a refrigerant sensor 37 detecting a refrigerant leaking from the refrigeration circuit; an opening/closing device for opening and closing the refrigerant piping; a bypass pipe 42 branched from the refrigerant piping; a bypass pipe throttle device adjusting a flow rate of the refrigerant flowing through the bypass pipe 42; and a control portion 50. The control portion 50 makes the opening/closing device close the refrigerant piping after increasing an opening of the bypass pipe throttle device, when the refrigerant sensor 37 detects the refrigerant.SELECTED DRAWING: Figure 1
