Bi-flow receiver/dehydrator for refrigeration system

摘要

A receiver dehydrator for a refrigeration system for heating and cooling accommodates flow in either direction. It comprises a canister with openings near the top for coupling to refrigerant lines, and tubes inside the canister extending from the openings to tube mouths at the bottom of the canister for either intake or withdrawal of liquid. A baffle between the mouths allows liquid passage from either mouth to the other but inhibits flow of gas bubbles. The baffle has many perforations for liquid flow and an inclined vane outside each opening directs rising bubbles away from the perforations to encourage migration to the top of the canister. Alternate perforations have vanes on opposite sides of the baffle for gas-liquid separation in either flow direction. A desiccant bag between each tube mouth and the baffle further aids in such migration.
