Abstract
An air-conditioning apparatus according to the present invention includes: a heat-source-side unit including a heat-source-side heat exchanger and a compressor; a plurality of load-side units including respective load-side heat exchangers and respective load-side expansion devices; and a relay unit connected between the heat-source-side unit and the plurality of load-side units by a first gas pipe and a first liquid pipe. The relay unit includes a gas/liquid separator which separates refrigerant supplied from the heat-source-side unit into gas refrigerant and liquid refrigerant, a gas-refrigerant supply pipe and a liquid-refrigerant supply pipe which are connected to the gas/liquid separator and each of the plurality of load-side units, a drain pan which is provided in a housing of the relay unit and which receives dew-condensation water, and a heat transfer body which is provided in the drain pan and which is in contact with the liquid-refrigerant supply pipe.
