Introduction of the light air-conditioning system of wuling
Wuling light is equipped with domestic 465 q - 1 perature of 35 °C or so, if the refrigerant directly to the heat from the exhaust to the atmosphere, it is impossible to achieve, because although refrigerant absorbs heat, but the actual temperature is lower than the air temperature, low temperature material can't transfer heat to the high temperature material, this is an obvious truth. At this time, use the vaporized refrigerant compressor pressure, the refrigerant in the case of no additional heat, temperature, up to 70 °C or so, with outside air is formed around 30 °C (_zuo3 you4) temperature difference, the condenser and the fan again, can easily achieve the goal of interior heat into the atmosphere. Simply put, the automobile air conditioning refrigeration is the compression process, the heat transfer process to the throttling process, the endothermic process. Then move on to the next cycle.
Wuling5 s computer system: Siemens, MOTOROLA, Delphi, united electronics, bosh. The air-conditioning circuit diagram is similar, the method of elimination method is the same.

The reason of the failure of the air-conditioning system and the maintenance of the system
There are two kinds of problems in air-conditioning system not refrigeration, which is the f
