PROBLEM TO BE SOLVED: To provide a refrigeration cycle device which prevents the degradation of defrosting performance by using heat stored in heat storage material and further improves heating performance.SOLUTION: A refrigeration cycle device includes: a four-way valve which switches a circulation direction of coolant flowing through a coolant pipe line; heat storage material which is arranged around a compressor and stores heat from an external part; a first pipe line which is branched on the way between the compressor and an indoor heat exchanger, passes through the heat storage material and is connected between a pressure reducer and an outdoor heat exchanger, of coolant pipe lines; a second pipe line which is branched on the way between the indoor heat exchanger and the pressure reducer of coolant pipe lines, passes through the heat storage material and is connected between the outdoor heat exchanger and an accumulator of the coolant pipe line; and a control device which closes the first bypass pipe line and opens a second bypass pipeline when switching circulation direction of coolant flowing through the coolant pipe line with the four-way valve and performing defrosting operation in the way of heating operation. |
