COOLING FAN CONTROL METHOD OF AIR CONDITIONER FOR AUTOMOBILES

摘要

The present invention applies only as to the manufacturing cost of a vehicle increases in accordance with the use of the expensive pressure sensor to regulate the speed of the prior art, cooling fans relates to a cooling fan control method for controlling a condenser, the heating value of the air-conditioning advanced vehicle and, as light vehicles and small cars in the speed of the cooling fan always rotates at a high speed only when there was a lot of energy consumption noisy problems.; Accordingly, the present invention when the temperature of the air more than a predetermined value by using an air temperature sensor 11 installed in the evaporator 10 passes through the evaporator 10, the engine control device 60, the speed of the cooling fan (31) the existing parts, as was a low speed rotation, when the temperature of the air passing through the evaporator 10 is not the predetermined value or less, the engine controller 60 is configured to be capable of rotating speed of the cooling fan 31 at a high speed the hameuroseo control the cooling fan 31 by, it is possible to reduce the manufacturing cost, to one so that it is possible to control the light vehicles and small cars also the speed of the cooling fan 31 without increasing the cost even more competitive product.
