INSTRUCTIONS (1) [Technical Field] The present invention relates to a method of protecting an air conditioner, and more particularly, to a main power supply connection using a bus air conditioner • A processing circuit that protects certain air conditioning units from damage due to insufficient power supply. - [Prior Art] Press, the main power supply of the general bus, mainly from the battery installed on the car body, when the engine is started, it also drives the generator to generate electricity, l replenish the battery power, the main power of the battery, It can be used to provide the power required for many equipment or parts in the vehicle. A large part of it is used to provide power for each unit of the air conditioning system, such as an electromagnetic clutch for connecting the engine and the compressor, a heat dissipation motor, and an evaporator. The internal air drum motor, etc., enables the bus air conditioning system to operate normally. [Summary of the Invention] However, when the battery or generator failure of the bus is damaged, causing the battery main power supply normal voltage value of 24V to decrease to a certain low voltage value (usually 22.7V), the magnetic force generated by the electromagnetic clutch electromagnetic coil will be generated. The suction force is reduced, so that the drive disc and the clutch pressure plate on the clutch plate cannot be tightly engaged, and then the slip produces relative rotational friction, which causes the drive disc to generate high heat and is transmitted to the electromagnetic coil on the drive disc, so that the electromagnetic coil is burned and damaged. At the same time, the compressor can not be operated; similarly, when the main power supply voltage of the cooling motor is insufficient, the speed of the heat-dissipating motor is also slowed, and the heat dissipation effect is deteriorated.
