摘要： A car air conditioner is free from the problem of insufficient and frustrating defrosting effect of a conventional air conditioner that becomes apparent when wet air is blown onto the misted front window pane of the car in a rainy season by selecting a defroster position on the outlet vent selection switch of the air conditioner. In the control circuit of the air conditioner, the defroster contact 2a of the outlet vent selection switch 2 is connected to a pulse shaping circuit 9 for generating a pulse whenever selected and the pulse shaping circuit 9 is by turn connected to the reset terminal PR of a D flip-flop circuit 8, while the inverted output terminal Q2 of the D flip-flop circuit 8 is connected to an AC relay 5 by way of a NOR-gate 10 that calculates the logical sum of the logical value "L" generated when the compressor contact 3a of flow rate control switch 3 is closed. Thus, when the flow rate control switch 3 is closed and the defroster contact 2a of the outlet vent selection switch 2 is selected, the circuit automatically drive the compressor to solve the problem.
