ABSTRACT:
An automotive air conditioning apparatus 10 is provided which includes a forced water supply system 9 and a heat pump system 14. A controller 16 controls the temperature of a second heat exchanger 38 of the heat pump system 14 to a desired temperature based on a preset temperature. The controller 16 also controls the temperature of the water circulating through the heat exchanger 20 of the forced water supply system 9 to a temperature at which the quantity of heat exchange between the air heated by the second heat exchanger 38 to the desired temperature and the heat exchanger 20 of the forced water supply system is minimized. According to this air conditioning arrangement, the temperature of the vehicle interior can be promptly raised without any capability drop being caused and thus, the heating efficiency of the apparatus being well enhanced.
