Filter Dryer

Filter Dryer Function

There are three main functions of the filter dryer for car air conditioners. The three functions are:

1. Filtering Freon Car

The main function of the dryer filter is to filter the dirt carried by the freon. If the dirt circulates in the AC system, it will contribute to the channels in the AC.

Such as the expansion valve channel will be easily clogged because this channel is very small in size. If the channel is clogged, then the air conditioner will not work optimally. With the filter dryer, it can filter dirt properly.

2. Absorbes Water in Freon

Another function of the dryer filter is to absorb the water in the freon or refrigerant. Because the water that circulates into the AC system can also cause damage and its performance will not be optimal.

When water enters the expansion valve line, it can freeze because the temperature in the line is very cold. When it becomes ice, it will clog the expansion valve channel. So it is better if the water contained in the freon must be removed using silica gel or a desiccant.

3. Temporarily Save Freon

Dryer Filter also serves to temporarily store freon before it is flowed into the expansion valve. This valve will channel according to the needs of the driver. You can adjust it with a heat sensitizing tube.

If the heat sensitiving tube requires freon, then the valve will spray it into the evaporator line. If it is not needed, the expansion valve will not spray it and the freon will be temporarily stored in the dryer filter.
