Filter dryers, in particular large - filter dryers, for stationary refrigeration plants as well as filter dryer cartridge for use in the case of such a filter dryers

摘要

For stationary refrigeration plants a certain filter dryers comprises a housing (1) with an inlet (6) and an outlet (7) for the refrigerant. In the housing (1) are two substantially identical filter dryer cartridges (8, 8 ') arranged. Each of these filter dryer cartridges (8, 8 ') comprises a hollow cylindrical housing cover (9, 9') from an inner and an outer cylinder wall as well as a lower and an upper annular end face is limited. One of these end faces (11, 11 ') is designed as a removable cover. In the interior of the housing cover (9, 9 ') is a loose bed (18, 18') of filter means is accommodated in a dry state. The housing cover (9, 9 ') have in the cylinder walls openings (15, 15', 17, 17 '), in such a way that the dryer in the interior of the filter cartridges (8, 8') of the beds (18, 18 ') can be substantially radially flows through. The paths traveled by the refrigerant flows through the beds (18, 18 ') must travel thus remain short and the throttling, which the refrigerant to the passage through the filter dryers, remains small.
