    • PURPOSE: To obtain sufficient heating capacity even in a cold district, utilize an existing heater unit, combine a combustion type heater with it by simple installing work, and make the most of exhaust heat of a traveling motor of an electric automobile be utilized for heating in a cabin. CONSTITUTION: An air conditioner for a vehicle is composed of a refrigerating cycle 4 in which a refrigerant compressor 20, a refrigerant water heat exchanger 21, a first pressure reducing means 22 and an outdoor heat exchanger 23 are connected in an annular shape to each other and a warm water cycle 5 in which a refrigerant water heat exchanger 21, a warm water heater core 52, an exhaust heat cooler 53 and a water pump 56 are connected in an annular shape to each other and a combustion type heater 55 is connected in parallel to the refrigerant water heat exchanger 21. At warm water heating time of a heat pump, warm water whose temperature is raised by heat of condensation of a refrigerant by the refrigerant water heat exchanger 21 is circulated to the warm water heater core 52, and necessary heating capacity is obtained, and at warm water heating time of a combustion heater, warm water whose temperature is raised by heat of combustion of fuel by the combustion type heater 55 is circulated to the warm water heater core 52, and sufficient heating capacity is obtained even in a cold district.
