Abstract: The present invention relates to a vehicular heat management system capable of inducing an increase in refrigerant superheat degree without unconditionally turning off a compressor when the refrigerant superheat degree on the discharge side of a chiller is less than or equal to a lower limit value.
The vehicular heat management system includes: a compressor; a condensing heat exchanger; an expansion valve; an evaporation heat exchanger; and a control part configured to, when a refrigerant superheat degree on a discharge side of the evaporation heat exchanger is lowered to a predetermined lower limit value or less, control, step by step, at least two devices directly involved in the increase and decrease of the refrigerant superheat degree to increase the refrigerant superheat degree until the refrigerant superheat degree exceeds the lower limit value.
