<p>A refrigeration cycle device characterized by being constructed such that it is equipped with a refrigerant circuit (6), wherein a compressor (1), a radiator (2), a cooler (3), an expansion means (4), and an evaporator (5) are connected in this order in a loop, with a refrigerant circulating therein, and with a heat medium circuit (9), wherein a heat medium circulation means (7), the cooler (3), the evaporator (5), and a heat exchanger (8) that is used for an external heat source are connected with heat medium piping (9a), with a heat medium circulating therein, with at least a portion of the heat medium transported from the external heat source-use heat exchanger (8) to the evaporator (5) by the heat medium circulation means (7) in the heat medium circuit (9) being transported to the cooler (3). When this refrigeration cycle device is operated with a fixed heating capacity, the amount of refrigerant that is circulated can be decreased by decreasing the power of the compressor (1), so the efficiency of the refrigeration cycle can be improved.</p> |
