Title:

HEAT PUMP SYSTEM

Document Type and Number:

WIPO Patent Application WO/2019/111621

Kind Code:

A1

Abstract:

This heat pump system has: a heat pump cycle (10); recovery parts (25, 35); and a high-temperature side heat reception part (20) and/or a low-temperature side heat reception part (30). The heat pump cycle has a compressor (11) that compresses and discharges a refrigerant, a radiator (12) that radiates heat of a high-pressure refrigerant compressed by the compressor, pressure reduction parts (15a, 15b) that reduce the pressure of the high-pressure refrigerant flowing out from the radiator, and heat sinks (16, 18) that evaporate a low-pressure refrigerant the pressure of which is reduced by the pressure reduction parts and sink heat. The recovery parts recover exhaust heat discharged from the compressor. The high-temperature side heat reception part causes the high-pressure refrigerant to radiate the heat recovered by the recovery parts. The low-temperature side heat reception part causes the low-pressure refrigerant to sink the heat recovered by the recovery parts.
