Accumulator-dehydrator assembly for an air conditioning system.

摘要

An accumulator-dehydrator assembly (15) for an air con- ditioning system comprising an accumulator housing (16) defining an enclosed chamber (17) including an inlet (18) and an outlet (19) in the upper end and a refrigerant and oil accumulator in the lower end, and a vapor drier canister assembly (20) comprising a one-piece plastic body (23) defining a closed top wall (25), a closed side wall (26) and an open bottom. The body (23) includes an integral outlet (22) projecting into and sealingly engaging the outlet (19) of the housing (16). A filter (35) is associated with the outlet (22) of the body (23) such that vapor or gaseous refrigerant flows through the filter (35) before passing through the outlet (22). A perforated plate (28) is provided in the bottom of the body (23) for holding desiccant (D) within the body (23). A refrigerant and oil tube (21) is mounted externally of the body (23) and has a lower end extending to the bottom of the chamber (17) of the accumulator housing (16) and has an upper end extending into the outlet (22) of the body (23). A filter (24) is associated with the lower end of the tube (21).
