摘要： A heat pump unit (200) includes: a circulation passageway (210) through which a heat medium circulates; a compressor (230) which includes an accommodation space (R) accommodating lubricating oil to be supplied to a compression mechanism (232, 234) and which increases the temperature of the heat medium by adiabatically compressing the heat medium; a condenser (240) which condenses the heat medium; an expansion valve (260) which decompresses and expands the heat medium; an evaporator (220) which evaporates the heat medium; and a controller (280) which controls drive of the compressor and the opening degree of the expansion valve. The controller is adapted to decrease the opening degree of the expansion valve so that the height of the liquid surface of the lubricating oil accommodated in the accommodation space is maintained to be greater than or equal to a preset threshold, and to stop operation of the compressor after completely closing the expansion valve, when receiving instructions to stop compression operation of the compressor.
