Car air conditioner

Abstract

Abstract PURPOSE:To blow out the cool air and warm air through the vent and foot blowout ports respectively by turning a compressor on when the compressor is off and an air mix door is near the full cold position at a high level mode. CONSTITUTION:The intake air temperature TIN detected by an intake air temperature sensor 26 is compared with the necessary blowout temperature T0 calculated; if the difference (T0-TIN) is greater than alpha, a compressor 4 is turned off; if T0<TIN or T0-TIN<=alpha, the compressor 4 is turned on. Thereby, the compressor 4 is turned on without fail under a condition that the opening of an air mix door 8 is near the full cold position, thus the air mix door 8 is moved to the hot side. Accordingly, the cool air is blown out through a vent blowout port 13 and the warm air is blown out through a foot blowout port 14 at a high level mode, and a comfortable car room condition can be obtained.
