PURPOSE:To facilitate defrosting while maintaining the temp. at a head area comfortably by enlarging the automatic control of blow-out mode to def. heat mode, and continuously changing the def. breed amount according to the head temp. CONSTITUTION:A means 100 operates the aimed opening of an air mix door 16 according to the thermal load within a cabin 21. A means 200 operates a mode control signal which determines the blow-out rates of vents and blow-out ports at foot area, according to the aimed opening and the temp. etc. of an evaporator 8. A means 300 drive/control a plurality of mode doors 22a to 22c based on the mode control signal. In this case, the mode control signal corresponds to a heat mode signal. A means 400 judges whether the temp. outside the cabin is lower than a specified level at which defrosting is required. When defrosting is needed, a means 500 decides the breed rate to the defrost blowout port 18 based on the upper area temp. of the cabin 21. |
