Most of the reasons for the poor cooling effect of automobile air conditioners are caused by the lack of Freon, but there are also some cases of compressor or heat dissipation problems.
The function of the condenser of the automobile air conditioner is to dissipate heat and cool down the high-temperature and high-pressure refrigerant vapor discharged from the compressor, so that it condenses into a liquid high-pressure refrigerant.
The washing product of the condensing net is alkaline and is slightly corrosive to the condenser, so it is very important to add water to reduce the concentration, because if the concentration is too high, the tube will be washed very cleanly, but the corrosiveness cannot be ignored.
