Vehicle heat management system

Abstract

A vehicular heat management system is disclosed and is configured to minimize high-pressure/high-temperature movement path sections in a refrigerant movement path extending from a compressor to a chiller and a refrigerant movement path extending from the compressor to a vehicle interior cooling heat exchanger. The system includes: a heat pump type refrigerant circulation line including a compressor, a high-pressure side heat exchanger, an outdoor heat exchanger, a chiller connected in series or in parallel to the outdoor heat exchanger, and a vehicle interior cooling heat exchanger connected in series or in parallel to the outdoor heat exchanger; and a refrigerant control part configured to, in a heat pump mode, depressurize and expand a refrigerant on the compressor side and selectively allow the refrigerant to flow toward at least one of the outdoor heat exchanger, the chiller and the vehicle interior cooling heat exchanger depending on an air conditioning condition.
