Refrigerant Filter Drier Function

Here are some details.

Refrigerant filter drier function.

6 issue of the news we covered the internal construction filtering and drying materials within a refrigerant filter drier. Steel liquid line filter driers are intended for use in all sizes and types of systems. This kind of filter drier is physically sized to minimize pressure and provide adequate volume for filtration and drying. One to adsorb system contaminants such as water which can create acids and two to provide physical filtration.

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. The refrigerant flow control device could be thermostatic expansion valve or simply a capillary tube. A filter drier in a refrigeration or air conditioning system has two essential functions. As important as the filter drier is many actually do not understand how it works.

At the heart of the drier is the desiccant held in its cylindrical metal container. Face seal driers and pencil driers. The word desiccate means to dry out. Filter drier perforated plate how filter driers work the refrigerant then leaves the filter driver and heads to the expansion valve.

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. So the refrigerant enters through the inlet it passes across the spring then surrounds the outside of the solid core. A filter is used to remove any particle such as dirt metal or chips from entering the refrigerant flow control. Evaluation of each factor is necessary to ensure proper and economical drier design.

The range of physical size desiccant type and amount allows them to be applied to virtually any refrigeration and air conditioning system. This month we ll deal with troubleshooting service and replacement of the filter drier. Filter driers play a very important role in the operation of air conditioning and refrigeration systems. Ge refrigerator was not cooling we replace filter dryer and copper line.

In last month s article inside filter driers which appeared on page 18 of the feb.
