Generally speaking, the load when the air conditioning system begins to work is large, and the circulation quantity of refrigerant is also large. After working for a period of time,
the load will be reduced, and the refrigeration dose required at this time will be reduced accordingly.
2, filtration: each part of the refrigeration system should be strictly cleaned and dried before leaving the factory, but when installing the pipeline, it may not pay attention to the dirt into the pipeline, the pipeline may also produce dirt,
such as oxide scale, refrigerant itself is not so clean, the compressor running powder and so on.
3, drying effect: used to absorb the water in Freon. Principle of automobile drier: automobile air drier is generally appeared in large buses or trucks, because the brake of these cars are required to use high pressure air brake.
The main role of the dryer is to be used to dry water in the high-pressure air, to avoid water in the air and corrosion of brake parts. There is a heating rod in the drying tank, which is automatically controlled. Generally,
when the temperature is lower than 5 degrees, the heating rod of the dryer works to dry the moisture in the high-pressure air
