Title:
HEAT PUMP
Document Type and Number:
WIPO Patent Application WO/2016/148080
Kind Code:
A1
Abstract:
This heat pump has: an accumulator that separates a liquid refrigerant from a gaseous refrigerant that returns to a compressor; a refrigerant intake channel that connects the compressor and the accumulator; a refrigerant return channel that returns the liquid refrigerant of the accumulator to the refrigerant intake channel; a first valve that is provided in the refrigerant return channel; a temperature sensor that detects the temperature of the refrigerant further to the compressor side than a point of merging between the refrigerant intake channel and the refrigerant return channel; a second valve that decompresses a portion of the liquid refrigerant that flows through a refrigerant channel between first and second heat exchangers; a refrigerant evaporator that gasifies the decompressed liquid refrigerant using waste heat from an engine; a gaseous refrigerant supply channel that supplies the gasified refrigerant to the accumulator; and a control device that, when the first valve is open, controls the aperture of the second valve on the basis of the temperature detected by the temperature sensor.
