A vapor compression refrigeration cycle device includes a main refrigerant circuit formed by sequentially connecting a compressor, a use-side heat exchanger, an intermediate heat exchanger, a first expansion device, and a heat source-side heat exchanger to one another through a refrigerant pipe; a bypass refrigerant circuit which branches off from the refrigerant pipe located between the use-side heat exchanger and the first expansion device, and which is formed by sequentially connecting a second expansion device, the intermediate heat exchanger, and a compression midstream of the compressor; and a controller. When a pressure ratio of discharge pressure of refrigerant discharged from the compressor and suction pressure of refrigerant sucked into the compressor is equal to or smaller than a reference pressure ratio, the controller is configured to control the compressor such that the number of rotations of the compressor is increased.
