A vehicular heat management system includes a refrigerant circulation line including a compressor, a high pressure side heat exchanger, a heat pump mode expansion valve, an outdoor heat exchanger, and a plurality of low pressure side heat exchangers installed parallel to each other. The refrigerant circulation line further includes a refrigerant pipe having an increased diameter portion formed by increasing the diameter of a specific refrigerant pipe portion among a plurality of refrigerant pipe portions affecting a refrigerant pressure in the refrigerant pipe portions on the intake and discharge sides of the compressor so that the specific refrigerant pipe portion has a larger diameter than other refrigerant pipe portions.
