Abstract
An air conditioner for an economically running vehicle includes a compressor driven by a vehicle engine, an evaporator, and a cold-storage heat exchanger having a cold storage material. The evaporator and the cold-storage heat exchanger are disposed in series in a refrigerant flow. When the compressor is operated, the cold storage material is cooled by low-pressure refrigerant in a cold storage mode. When the operation of the compressor is stopped, refrigerant circulates between the evaporator and the cold-storage heat exchanger, so that refrigerant evaporated in the evaporator is cooled and liquefied by the cold storage material in a cold release mode. Further, a flow direction of refrigerant flowing through the evaporator in the cold storage mode is the same as that in the cold release mode.
