Abstract

PURPOSE:To ascertain the normal operation of an air conditioner constructed to check the blowing off of air until a fixed temperature is obtained by providing an indication lamp to be lit between the switching on of the air conditioner and the blowing off of air. CONSTITUTION:When an air conditioner operation switch or a fan switch 2 is on and both of engine water temperature and outside temperature are under a fixed value, switches 6 and 7 are off not to excite a relay 9, and the operation of air conditioning is carried on without controlling the amount of air. At this stage, a transistor 10 is connected to light an indication lamp 11a. Then, when the water temperature is risen to the fixed value, the switch 6 is on to excite the relay 9, and a transistor 8 is connected to apply a voltage from an electric source 4 to a blower fan motor 1. Accordingly, the control of the amount of air is carried on. Meanwhile, the transistor 10 is disconnected, and the indication lamp 11a is put out. The control of the blowing off of cool air is similarly carried on.
