Structure of the car air-conditioning system
Automobile air conditioning consists of compressors, condensers, air conditioning pipes, evapotors and electrical circuits. It uses the constantly changing frequency cycles of refrigerants to achieve refrigeration effects. Liquid refrigerants are characterized by the ability to vaporize at constant temperatures, to become vapour absorbers of the surrounding heat at heat and, at cold, to release the fluid itself. An air-conditioning system uses the refrigerant characteristic to remove the heat from the area inside the car and move it outside the car。
Vehicle air-conditioning system inspection maintenance
Compressors: the installation of a support frame for the compressor shall not be relaxed. Passive tripple belts are suitable and too loose can cause slippage, resulting in reduced compressor speed and insufficient cooling; too tight and increased wear of the belt, resulting in premature damage to arc bearings. Compressor refrigerator oil surfaces should be at a specified level, normally at very low consumption levels, and if refrigerated oil is not visible from the compressor's oil lens, it should be maintained in a timely manner。
Condensers: in order to ensure that the entire air conditioning system is working properly, the cooling process is good and it is essential to keep the surface clean. To this end, condensers are often washed to prevent oil pollution, soil and other impurities from being attached to the condensers. Be careful not to knock down the condensers, let alone damage the pipes。
Evaporationers: air filters are generally installed at vents of evaporation, which should be cleaned once a week so as not to hinder air flow by adsorbing dust and impurities into air filters。
Air-conditioning pipelines: the wear and age of the air-conditioning system's hoses is regularly checked. A large number of rubber hoses are used in air-conditioning systems and if they are worn, they explode when the ambient temperature increases and the refrigeration system works, resulting in refrigerants, refrigerated oils and complete failure of the air-conditioning system. If the hose is broken and the air conditioner continues to function, this will result in large quantities of soil and water entering components such as compressors, rendering the entire cooling system obsolete. Therefore, it is important that rubber hoses be regularly checked and that wear and tear be processed in a timely manner, that broken parts be covered with cloth and that air conditioning be discontinued and sent for repair as soon as possible。
Electrical circuits: frequent inspection of air conditioning circuits to prevent thermal insulation of wires. When the air-conditioning system is burned, it is necessary to check the problem, to replace it with an electrical tube, and not short-link it, otherwise there is a risk that the entire circuit will be burned or that other circuits on the vehicle will be adversely affected。
The cleaning of air-conditioning systems consisted mainly of cleaning of air-conditioning vents, conducting pressure tests and cleaning of evaporation boxes. The first is the cleaning and debacterization of air-conditioning vents, which are essential routes for air-conditioning venting, and the dusting and bulk of bacteria on the venting walls will blow into the car as air-conditioning vents. Second, the test of the pressure system is primarily to check whether the refrigerant is sufficient or whether it is leaking. Finally, cleaning the dust from the evaporation box。
