HEAT MANAGEMENT SYSTEM FOR VEHICLE

WIPO Patent Application WO/2024/101672

A1

The present invention relates to a heat management system for a vehicle, configured such that, during a heat pump mode, refrigerant distribution amounts for an outdoor heat exchanger and a chiller may be regulated according to a condition, thereby restricting refrigerant flow distribution to the unnecessary part among the outdoor heat exchanger and the chiller according to the condition, and thus reducing unnecessary flow path resistance and pressure drop of the refrigerant resulting from refrigerant flow distribution to the unnecessary part, and reducing heat pump performance degradation resulting therefrom, the heat management system for a vehicle comprising a heat pump-type refrigerant circulation line having: a compressor; a high-pressure-side heat exchanger; and an outdoor heat exchanger and a chiller connected in parallel to each other, wherein the heat management system for a vehicle has a refrigerant distribution amount control unit capable of regulating refrigerant distribution amounts for the outdoor heat exchanger and the chiller according to an air conditioning condition during a heat pump mode.
