Refrigerant Filter Drier Function

A filter drier in a refrigeration or air conditioning system has two essential functions.

Refrigerant filter drier function. At the heart of the drier is the desiccant held in its cylindrical metal container. Filter drier perforated plate how filter driers work the refrigerant then leaves the filter driver and heads to the expansion valve. Filter driers are devices used in a hvac system that are a combination of filter and dryer or drier. A filter is used to remove any particle such as dirt metal or chips from entering the refrigerant flow control.

The refrigerant flow control device could be thermostatic expansion valve or simply a capillary tube. Heat pump liquid line filter driers sporlan hpc series. In relatively small systems where the cost of a receiver is difficult to justify a combined filter drier receiver type dmc can be used it basically consists of a large housing that combines the functions of a receiver and a drier core the world s most commonly used type of drier thanks to kitchen appliances is the pencil drier. One to adsorb system contaminants such as water which can create acids and two to provide physical filtration.

Evaluation of each factor is necessary to ensure proper and economical drier design. 6 issue of the news we covered the internal construction filtering and drying materials within a refrigerant filter drier. This kind of filter drier is physically sized to minimize pressure and provide adequate volume for filtration and drying. In last month s article inside filter driers which appeared on page 18 of the feb.

So the refrigerant enters through the inlet it passes across the spring then surrounds the outside of the solid core. Filter driers play a very important role in the operation of air conditioning and refrigeration systems. Absorbing moisture preventing acids. Face seal driers and pencil driers.

The hpc series sealed model filter driers provide excellent solid particle removal moisture scavenging as well as acid capture capability to ensure the full life capacity and efficiency of heat pump air conditioning systems up to 20 tons. Here are some details. This month we ll deal with troubleshooting service and replacement of the filter drier. The range of physical size desiccant type and amount allows them to be applied to virtually any refrigeration and air conditioning system.

Ge refrigerator was not cooling we replace filter dryer and copper line.
