Abstract
A heat pump cycle device includes a compressor, a branch part, a heating unit, a heating-unit side decompression unit, a bypass passage, a bypass flow rate adjustment unit, a mixing part, a target temperature determination part configured to determine a target temperature that is a target value of an object temperature of the heating object heated by the heating unit, and a target low-pressure determination part configured to determine a target low pressure that is a target value of a sucked refrigerant pressure of the refrigerant to be sucked into the compressor. When the object temperature is lower than the target temperature during execution of a hot gas mode, a high-pressure rise control is performed to raise a discharged refrigerant pressure of the refrigerant flowing into the heating unit.
