Abstract

This air-conditioning device comprises: a heat source unit which has a compressor, a first flow path switching device, and a heat-source-side heat exchanger; indoor units which each have a throttle device and a use-side heat exchanger; a liquid pipe and a gas pipe which connect the heat source unit and the indoor units; a refrigerant circuit which is configured from the compressor, the first flow path switching device, the heat-source side heat exchanger, the throttle device, and the use-side heat exchanger connected by pipes through which a refrigerant is circulated; a first bypass pipe which connects the liquid pipe and the gas pipe; a second bypass pipe which branches off from the first bypass pipe and discharges the refrigerant to the exterior; a second flow rate switching device which opens and closes the heat-source-unit-side of the liquid pipe, the indoor-unit-side of the liquid pipe, and the first bypass pipe side; a first opening-closing device which is provided in the gas pipe; a second opening-closing device which is provided in the second bypass pipe; a refrigerant leakage detector which detects the leakage of the refrigerant from the refrigerant circuit; and a control device which, upon detecting leakage of the refrigerant during a cooling operation, closes the second opening-closing device and starts a pump down operation. After the completion of the pump down operation, the control device closes the first opening-closing device, and, upon detecting leakage of the refrigerant, opens the second opening-closing device.
