Abstract: The present invention relates to a vehicular air conditioning system and provides a vehicular air conditioning system capable of preventing overheating of an inverter that controls the rotation speed of an electric compressor without cutting off the inverter, and consequently preventing the stoppage of an air conditioner due to the cut-off of the inverter and the resultant stoppage of cooling of a passenger room. The vehicular air conditioning system includes an electric compressor, an inverter configured to control a rotation speed of the electric compressor, and a control part configured to execute control so that a refrigerant flow rate on an inlet side of the electric compressor increases when a temperature of the inverter is equal to or higher than a preset overheating warning temperature.

Abstract: The present invention relates to a heat pump system for a vehicle. The heat pump system includes a refrigerant-coolant heat exchanger for exchanging heat between refrigerant circulating through a refrigerant circulation line and coolant circulating through electronic units of the vehicle. The heat pump system can operate the heat pump mode even though outdoor air temperature is zero or lower or frosting is formed on the external heat exchanger because waste heat of the electronic units is retrieved through the refrigerant-coolant heat exchanger, thereby further enhancing heating performance and efficiency.
