HEAT MANAGEMENT SYSTEM FOR VEHICLE

WIPO Patent Application WO/2023/003269

A1

The present invention relates to a heat management system for a vehicle. The purpose of the present invention is to respond to the occurrence of icing in an outdoor heat exchanger without restricting the refrigerant flow to the outdoor heat exchanger when the icing occurs in the outdoor heat exchanger under a heat pump mode condition, and to prevent instability of the refrigerant flow in a refrigerant circulation line due to the refrigerant flow restriction to the outdoor heat exchanger and a heating performance degradation phenomenon inside the vehicle due to the refrigerant flow instability. In order to achieve the purpose, a heat management system for a vehicle includes a heat pump type refrigerant circulation line having a compressor, a high-pressure side heat exchanger, an outdoor heat exchanger, a plurality of expansion valves, and a low-pressure side heat exchanger, the heat management system comprising: a first expansion valve installed on an upstream side of the outdoor heat exchanger; a second expansion valve installed on a downstream side thereof; and a control unit controlling the opening degrees of the first and second expansion valves on the upstream and downstream sides of the outdoor heat exchanger according to whether icing occurs in the outdoor heat exchanger under a heat pump mode condition.
