Abstract

PURPOSE:To improve capacity of an air conditioner, by a method wherein a radiator cooling fan which is capable of cooling a part of a radiator and a condenser is turned on or off automatically according to variation of water temperature, and full force running of a cooling fan is enabled at low speed travelling. CONSTITUTION:If an air conditioner switch 16 is turned on when a temperature of a cab is high and a thermoswitch 17 has been turned on, an air conditioner relay 15 and a fan motor relay 21 are turned on, and a fan motor 9 of a cooling fan 7 of a condenser 3 and a fan motor 10 of a cooling fan 8 of a radiator 2 become operative simultaneously. On the other hand, when the thermoswitch 17 is turned off both the fan motors 9 and 10 are suspended. In this instance, when a thermoswitch 22 is turned on due to an increase of cooling water temperature, the fan motor 10 is actuated and the radiator 2 is cooled as the thermoswitch 22 is connected with the fan motor 10 in series with the relay 21. With this device, the maximum operation of the air conditioner at low speed travelling can be carried out.
