Receiver Desiccant Dryer with Filter

摘要

A receiver drier 12 for the refrigeration system of a vehicle air conditioning system has a lower condenser section 31 and an upper sub-cooling section 22 within an elongate housing 26 having an inlet 42 positioned in a first section 31 and an outlet 46 in a second section 36; in use, the inlet receiving condensed refrigerant from the condenser section of a condenser unit (10 fig 1). The drier has a first chamber 56 in the first section containing a desiccant for drying refrigerant from the inlet and a second chamber in the second section containing a filter 80 for filtering the dried condensed refrigerant. The condensed refrigerant is conveyed to the outlet via the filter by a conduit 58 defined between an internal wall 50 and an external wall 28 of the elongate housing, the internal wall separating the desiccant chamber from the conduit.
