<p>PROBLEM TO BE SOLVED: To quickly establish a refrigerating cycle by quickening the rise of a compressor, and improve heating performance (immediately heating property) by arranging warming means to warm the compressor in an air conditioner for an automobile called a dual air conditioner. SOLUTION: In an air conditioner for an automobile having a front unit 10 and a rear unit 20, when a rear seat is heated when an outside air temperature is low at heating operation starting time, first of all, a solenoid valve 14 is closed, and a solenoid valve 26 is opened, and a water valve 31 is opened, and a four-way valve 4 is set in an illustrated condition. When a compressor 2 is turned on in this condition, a low temperature-low pressure refrigerant flowing in a sub-evaporator 30 is heated by engine cooling water, and becomes a higher temperature, and is sucked in the compressor 2. In this case, warm water of a heater core 12 is flowed in a compressor warmer 50, and a surface of the compressor 2 is warmed, and the rise of the compressor 2 is quickened, and a refrigerating cycle is quickly established.</p> |
