HEAT EXCHANGING SYSTEM

摘要

A heat exchanging system (1) exchanging heat between refrigerant and a battery (61) includes: a compressor (12) circulating refrigerant; a heat exchanger (14) exchanging heat between the refrigerant and outside air; an expansion valve (16) decompressing the refrigerant; a heat exchanger (18) exchanging heat between the refrigerant and air-conditioning air; a heat exchanging portion (60) connected in parallel with the heat exchanger (18) and exchanging heat between the refrigerant and the battery (61); a bypass passage (71) providing fluid communication between a path of the refrigerant between the compressor (12) and the heat exchanger (14) and a path of the refrigerant between the expansion valve (16) and the heat exchanger (18); an expansion valve (76) provided in the bypass passage (71) and decompressing the refrigerant flowing through the bypass passage (71); and a selector valve (72) allowing or interrupting flow of the refrigerant via the bypass passage (71).
