Car air conditioner dryer

(1) Liquid storage function: Liquid storage is used to store and supply the liquid refrigerant in the refrigeration system, so that it can compensate and adjust the profit and loss of the liquid refrigerant when the working conditions change. Generally speaking, when the air conditioning system starts to work, the load is large, and the circulating amount of refrigerant is also required. After a period of time, the load will be reduced, and the required amount of refrigerant will be reduced accordingly. Therefore, when the load is large, the liquid refrigerant in the accumulator is replenished, and when the load is small, the liquid refrigerant can be stored. At the same time, due to the open-type compressor and the rubber connecting hose, there is always a certain amount of refrigerant leakage, and the liquid reservoir can also make up for the small amount of refrigerant leakage in the system.

(2) Filtration: All components in the refrigeration system should be strictly cleaned and dried before leaving the factory. However, when installing the pipeline, it is possible to inadvertently bring in dirt, and the pipeline may also produce dirt, such as oxidation. The refrigerant itself is not so clean, the powder wear debris when the compressor is running, and so on. These mechanical impurities and dirt are removed by filtration. Ensure that the refrigerant circulates smoothly, and will not affect normal operation due to blockage.

(3) Drying effect: used to absorb water in freon. Moisture comes from the lack of strict drying of the refrigeration system, or the ingress of air, or the water dissolved in the refrigerant. The presence of moisture may cause "water blockage". On the other hand, Freon is very easy to dissolve in water to form an acidic substance, which will further corrode the air-conditioning pipes, so the water in the pipes must be removed.
In the air-conditioning refrigeration system, the function of the filter drier is to absorb the moisture in the refrigeration system, block the impurities in the system so that it cannot pass, and prevent the ice block and dirty blockage of the refrigeration system pipeline. Since the most easily blocked part of the system is the capillary tube (or expansion valve), the filter drier is usually installed between the condenser and the capillary tube (or expansion valve). The filter drier used in the air conditioner is thicker and shorter than the filter drier used in the refrigerator. Dry filter is abbreviated as dryer, there are two kinds of dry filter and filter.
