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.

Vehicular heat management system

The present invention relates to an air conditioner for a vehicle and a control method thereof, which can calculate the range of discharge temperature to the interior of the vehicle, set the upper limit of the discharge temperature, and control the degree of opening of a temp door such that the discharge temperature to the interior of the vehicle gets lower than the upper limit, thereby preventing air of discharge temperature above the upper limit from being discharged to the interior of the vehicle and preventing displeasure or personal injury that may be caused when air of high temperature is discharged.

Air conditioner for vehicle and control method thereof

An air conditioning system for motor vehicles includes a compressor, a condenser, a plurality of air conditioning units connected in parallel with each other with respect to the compressor and the condenser, and a flow rate control unit configured to, when a specific one of the air conditioning units is additionally turned on or is turned off, prevent occurrence of a sudden change in refrigerant amount in the remaining air conditioning units.
