Disclosed is a heater using a heat pump cycle. The heater using a heat pump cycle according to the present invention comprises: a heat exchanger; a supercooling adjusting part for introducing refrigerant at a first side, which has been recovered by the heat exchanger, to one side, and introducing supercooled refrigerant at a second side, which has been cooled by an evaporation/condensation outdoor air conditioner unit, to the other side to exchange heat; a compressor for compressing the refrigerant at the second side heated by the supercooling adjusting part; an evaporation/condensation outdoor air conditioner unit for supercooling the refrigerant at the first side cooled after passing the supercooling adjusting part; and a gas/liquid separator for separating the refrigerant, which has been supercooled by the evaporation/condensation outdoor air conditioner unit, into gas and liquid, supplying the gasified refrigerant as the refrigerant at the second side to the supercooling adjusting part, and supplying the liquid refrigerant to the evaporation/condensation outdoor air conditioner unit. Accordingly, the flow of the refrigerant in liquid state can be facilitated by separating the refrigerant in gaseous state from the refrigerant in liquid state in a pipeline via the gas/liquid separator installed on a pipeline at the refrigerant outflow side of the evaporation/condensation outdoor air conditioner unit, and heat-conducting performance can be improved by facilitating the flow of refrigerant in liquid state via a refrigerant-circulating pump as the slowly flowing refrigerant in liquid state flows more slowly at low temperature. |
