Claim 0:
1. A vehicular heat management system provided with a heat pump type refrigerant circulation line that cools and heats specific air conditioning regions by generating hot air or cold air depending on a flow direction of a refrigerant, comprising:
a compressor configured to suck, compress and discharge the refrigerant;
a high-pressure side heat exchanger configured to dissipate heat of the refrigerant discharged from the compressor;
an outdoor heat exchanger configured to allow the refrigerant to exchange heat with an air outside the vehicle;
an expansion valve configured to depressurize the refrigerant flowing out of the high-pressure side heat exchanger or the outdoor heat exchanger; and
one or more low-pressure side heat exchangers configured to evaporate the depressurized refrigerant,
wherein the outdoor heat exchanger and the low-pressure side heat exchangers are connected in series or in parallel depending on an air conditioning mode.
