Title:
HEAT PUMP CYCLE
Document Type and Number:
Japanese Patent JP2019074250
Kind Code:
A
Abstract:
To provide a heat pump cycle which achieves high heat exchange efficiency.SOLUTION: A heat pump cycle includes a compressor 11, a heat exchanger 12, a gas-liquid separator 17, and an outdoor heat exchanger 15. The heat pump cycle includes: a main circuit 10 which connects the compressor, the heat exchanger, the gas-liquid separator, and the outdoor heat exchanger to cause a refrigerant to flow therein; an exhaust heat recovery heat exchanger 31; and an exhaust heat recovery circuit 30 forming a passage which reaches the compressor via the exhaust heat recovery heat exchanger without going through the outdoor heat exchanger. The heat pump cycle includes an expansion valve 32 which is provided at the upstream side of the exhaust heat recovery heat exchanger in the exhaust heat recovery circuit and expands the refrigerant in the exhaust heat recovery heat exchanger so that the refrigerant changes its phase from a liquid phase to a gas phase.SELECTED DRAWING: Figure 1
