Filter-driers

Filter driers

With halocarbons, significantly reduce the moisture content of the refrigerant circuit is minimized by careful drying of components and installation of drying agents in the system. In General the form of land capsule charged with a solid desiccant, such as activated alumina or zeolite (a molecular sieve), located in the liquid line ahead of the expansion valve. These capsules, must have filters to prevent the loss of drying agent in the chain, and therefore form an effective filter-dehydrator also protect the valve with a bore diameter from damage to the small trash, Fig. 9.10.

Large dryers are made so they can be opened, and waste drying agent is removed and replaced with new ones. Small size, disposable. Dryers can also be used in the suction line. Suction line filter-driers are temporary installation for cleaning of the system after repair, and must be destroyed in case, if the pressure drop is becoming 1K more than when new.
