Filter dryer

The filter elements of the air-conditioning system are referred to as either filter dryers or accumulators, depending on the type of system involved. The job of the filter dryer is to extract foreign matter and moisture from the refrigerant. The liquid refrigerant enters the filter dryer, flows through a hygroscopic filter and leaves the filter-dryer again in a liquid state.

The top part of a filter dryer is used simultaneously as a compensation chamber and the bottom part is used as a refrigerant store to compensate for pressure fluctuations in the system. Depending on its design, the filter dryer can only remove a certain amount of humidity - then the drying medium is saturated and no longer in a position to absorb further humidity. Therefore, the filter dryer must normally be replaced every 2 years or each time the refrigerant circuit is opened. Ageing of the filter dryer can lead to severe defects in the air-conditioning system.
