Title:
AIR-CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/163058
Kind Code:
A1
Abstract:
Provided is an air-conditioning device capable of suppressing the impact of refrigerant transmitted to an opening-closing device that opens and closes refrigerant piping.　The present invention comprises: an outdoor unit 20 that is provided with a compressor 21; an indoor unit that contains a user-side heat exchanger; a refrigeration circuit that is formed by the compressor 21 and the user-side heat exchanger being connected by the refrigerant piping, and circulates the refrigerant; a refrigerant sensor 37 that detects the refrigerant leaking from the refrigeration circuit; an opening-closing device that opens and closes the refrigerant piping; a bypass pipe 42 that is branched from the refrigerant piping; a bypass pipe throttle device that adjusts the flow rate of the refrigerant flowing in the bypass pipe 42; and a control unit 50. When the refrigerant sensor 37 detects the refrigerant, the control unit 50 increases the opening degree of the bypass pipe throttle device and then causes the opening-closing device to close the refrigerant piping.
