Document Type and Number:
WIPO Patent Application WO/2023/281646
Kind Code:
A1
Abstract:
An air-conditioning device according to the present invention comprises: a refrigerant circuit through which a refrigerant flows and in which a compressor, a heat source-side heat exchanger, a throttle device, a load-side heat exchanger, and a shutoff valve are connected in this order by pipes; a heat source-side fan which blows air to the heat source-side heat exchanger; a leak detection means for detecting refrigerant leaks; and a control device which carries out a cooling operation. The control device, when the leak detection means has detected a refrigerant leak during the cooling operation, reduces the operating frequency of the compressor, raises the RPM of the heat source-side fan, and then closes the shutoff valve.
