초록 ▼

A heat pump type air conditioner for an automotive vehicle includes a vapor-compression refrigeration system which is provided with a compressor. An outer condenser and an inner condenser are serially connected to the compressor through a three-way valve. A bypass passage of the outer condenser communicates the compressor and the inner condenser through the three-way valve. The inner condenser is connected to an inner evaporator through an expansion valve. A refrigerant heater for heating refrigerant of the system is disposed upstream and/or downstream of the inner evaporator. The refrigerant heater is controllably operated by a control unit according to a refrigerant condition indicative signal from a refrigerant condition detector. Therefore, the air conditioner generates a sufficient heating performance even just after the start of an engine of the automotive vehicle while realizing a dehumidifying heating.
