APPARATUS FOR PREVENTING THE OPERATION OF AIRCONDITIONER IN A CAR DURING OVER-HEATING OF ENGINE

摘要

The present invention relates to a device for preventing an air conditioner operation when the engine is overheated, and the conventional air conditioner has a problem of causing an overheating of the engine by using excessive output of the engine when it is used for a long time with the operation of the engine. The apparatus of the present invention installs a coolant temperature sensor 14 for measuring the temperature of the coolant in a radiator in which the coolant of the engine circulates, and transmits the measured signal and the set temperature (115 ° C.) to the temperature rise sensitive switch unit 10. The overheat state of the engine is determined by inputting, and the temperature rise sensitive switch unit 10 is connected to the earth terminal of the air conditioner relay 40 for supplying power to the compressor 70 to a signal for determining the overheat state of the engine. Therefore, the ground is cut off, and at the same time, the switch of the air conditioner relay 40 is turned off so that the power of the compressor 70 is cut off.;Therefore, the vehicle using the apparatus of the present invention has the effect of prolonging the life of the vehicle and improving the power by preventing the overload and overheating of the engine from being promoted by limiting the operation of the air conditioner in the overheating state of the engine.
