Filter-drier, in particular large scale filter-drier, for stationary refrigeration installations as well as filter-drier cartridge for use in such a filter-drier

摘要

A particular for stationary refrigeration systems filter dryer comprises a housing (1) having an inlet (6) and an outlet (7) for the refrigerant. In the housing (1) comprises two substantially identical filter-drier cartridge (8, 8 ') are arranged. Each of these filter drier cartridge (8, 8 ') comprises a hollow cylindrical cartridge housing (9, 9') which is bounded by an inner and an outer cylinder wall as well as a lower and an upper annular end face. One of these end faces (11, 11 ') is designed as a removable lid. In the interior of the cartridge housing (9, 9 ') is a loose fill (18, 18') housed of filter drying agent. The cartridge housing (9, 9 ') in the cylinder walls through holes have (15, 15', 17, 17 ') in such a way that the inside of the filter drier cartridge (8, 8') located beds (18, 18 ')) in the can be substantially radial flow. The paths that must traverse the refrigerant passes through the lifting devices (18, 18 '), thus remain short and the restriction experienced by the refrigerant on the passage through the filter dryer, remains small.
