INTEGRATED THERMAL MANAGEMENT SYSTEM AND VEHICLE

WIPO Patent Application WO/2023/185268

A1

An integrated thermal management system (1000) and a vehicle. The system (1000) comprises: a heat pump subsystem (100) for exchanging heat with a passenger compartment (60) and a battery (70) of a vehicle; a high-pressure cooling subsystem (200) for exchanging heat with a high-pressure system (11) and a heat pump subsystem (100) of the vehicle; a battery self-heating subsystem (300) for performing heating for the charging and discharging of the battery (70); an air heating subsystem (400) for exchanging heat with the passenger compartment (60), the heat pump subsystem (100) comprising a compressor (1) and a control valve (33), one end of the control valve (33) communicating with a gas-discharge port of the compressor (1), and the other end of the control valve (33) communicating with a gas-return port of the compressor (1), or communicating with a gas-return port of the compressor (1) by means of a gas-liquid separator (27); and a control subsystem (500) for controlling the control valve (33) to bring the gas-discharge port of the compressor (1) into communication with the gas-return port of the compressor (1), so as to achieve gas supplementation and enthalpy increase.
