2012
A three-way valve (switching device) (42) is provided between an intake tube of a compressor (6) and a four-way valve (8), making possible a switch between a tube (25) draining refrigerant directly from the four-way valve (8) into the intake tube of the compressor (6) and a tube (38) draining refrigerant from the four-way valve (8) into the intake tube of the compressor (6) through an alternate heat exchanger (heat storage tank (32), heat storage exchanger (34), heat storage material (36)) for refrigerant heating; and by controlling the three-way valve (switching device) (42) during defrosting operation, refrigerant flowing to an indoor heat exchanger (first heat exchanger) (16) and an outdoor heat exchanger (second heat exchanger) (14) flows to the alternate heat exchanger (heat storage tank (32), heat storage exchanger (34), heat storage material (36)) via the four-way valve (8), and is guided to the intake tube of the compressor (6).
