Many owners of their own car's air conditioning maintenance is not particularly aware, under normal circumstances, there is not cooling or heating is not the case, many people think is fluorine less. The fact is, under normal circumstances, the car is not often fluoridation.
Automotive air conditioning is not cooling or air conditioner is the lack of common failures, common in the cooling system for leaks problem because modern cars R134a refrigerant used strong penetration sake. Summed up in three main areas: air-conditioning system mechanical failure, air-conditioning system electrical circuit fault, refrigerant and refrigerant oil failure.
According to the Throttle Body Kero understand the main car air conditioning refrigerant injected frequently check the amount of the storage tank is equipped with a peephole (sight glass) of the car, as long as the peephole observed from the flow of the refrigerant can judge refrigeration dose.
Maintenance of air-conditioning system must be carried out by professional and technical personnel, and the use of equipment, work environment, there are stringent requirements. Work environment more clean, repair air conditioning systems normally use the more durable, less maintenance times, the possibility of refrigerant leakage lower. Generally the system to escape 0.1kg each refrigerant leak detector with a new generation of electronic check R12, R134a slight leakage.
Mechanical failure include air-conditioning system compressor failure, condenser and fan failure, blower failure, Drier, expansion valve and evaporator fault fault. Determine whether the compressor drive belt failure depends on whether the aging, cracks, loose or too tight, affecting power transmission. Internal parts damaged or worn, the impact compression performance, the performance of the compressor abnormal noise. Channeling gas compressor cylinder head gasket, intake and exhaust valve damage, the impact compression performance.
Air quality of the cooling effect of the condenser fins clean the condenser surface of the dust cover debris will reduce cooling efficiency. Upon reboot, the air conditioning system pressure, overheating of the compressor and related parts are severely affected. North wind large, high speed, large numbers of insects are often adsorbed on the condenser, and therefore often condenser fins for professional cleaning. It is understood that clean air inside the fan switch on the oil, dust, insect stains and other debris, can prolong life of air conditioning, and effectively out of the car everyday except breeding mold, bacteria and smoke, etc., long-term fresh and fragrant air.
Evaporator is directly facing the compartment hair, its intake is directly related to the cleanliness of the occupant's health. Pay attention to timely replace the air filter, air filter is air inlet filter is usually installed in the engine compartment near the windshield down position. If you do not replace the air filter for a long time, above the dust absorption will be more and more, and there will be air conditioning fan intake compartment, affecting the health of the crew.
According to theThrottle Body Kero noted, R12, R134a air conditioning systems high and low pressure service valve chuck do not GM. High-end models of air-conditioning systems are proprietary technology, maintenance, have the original model and year of production corresponding maintenance manual provides a variety of data indicators; also want to check the nameplate on the system components, as required using a different compressor lubricants . Not required to supplement or replace the oil may cause damage to the compressor. Known by the maintenance manual to find out what type of refrigerant charge volume, oil type, and then follow stringent technical requirements on air-conditioning air-conditioning system can guarantee the normal work and life extension. |
