Abstract
A heat pump type air conditioner for an automotive vehicle is provided with a compressor to which an outer condenser and a inner condenser are connected through a three-way valve. The inner condenser is connected to an inner evaporator through an expansion valve. The air conditioner further includes a control unit which defines a relationship among a heating property, a physical amount according to which workload of the compressor is varied, and thermal operating condition of at least one of the inner evaporator and the inner condenser. The control unit determines the physical amount at a value from the relationship for the heating property and the detected thermal operation condition by sensors, and controls the compressor according to the determined physical amount.
