Heat management system for vehicle

Abstract

A vehicular heat management system configured to adjust the amount of refrigerant distributed to an outdoor heat exchanger and a chiller depending an air conditioning conditions in a heat pump mode is disclosed, which allows reduction of unnecessary refrigerant flow path resistance and pressure loss due to distribution of refrigerant to an unnecessary part and resultant decrease in heat pump performance by limiting the distribution of the refrigerant to an unnecessary part among the outdoor heat exchanger and the chiller depending on the conditions. The system includes: a heat pump type refrigerant circulation line including a compressor, a high pressure side heat exchanger, and an outdoor heat exchanger and a chiller connected in parallel to each other; and a refrigerant distribution amount control part configured to control an amount of refrigerant distributed to the outdoor heat exchanger and the chiller according to air conditioning conditions in a heat pump mode.
