Description

Technical Field

[0001] The utility model relates to the technical field of drying filters, in particular to a bidirectional energy-saving refrigeration system drying filter. Background Art

[0002] Filter driers are installed in the piping of air conditioning and refrigeration systems, typically between the condenser and the expansion valve. They effectively prevent the accumulation of contaminants flowing in one direction while also absorbing moisture from the refrigerant. The filter drier's internal structure combines drying and filtering, effectively preventing filtered and soluble matter from entering the system's key components, thereby ensuring optimal system operation.

[0003] The Chinese utility model patent with the authorization announcement number "CN217383389U" is specifically "a bidirectional energy-saving refrigeration system drying filter". Its beneficial effects record that "the bidirectional energy-saving refrigeration system drying filter, by providing a tightening component, will slowly shrink the movable card tube into the inside of the fixed sleeve tube under the drive of the spring when a gap is generated in the desiccant inside the desiccant storage cylinder, or the movable card tube and the fixed sleeve tube will move toward each other, thereby re-clamping the desiccant in the gap generated inside the desiccant storage cylinder, and at the same time, the gap is re-filled, thereby achieving the purpose of automatically filling the gap with the remaining desiccant in the desiccant storage cylinder when the desiccant inside the desiccant storage cylinder is used for a long time, thereby avoiding the problem of poor filtration of humid air caused by the gap generated by the desiccant inside the desiccant storage cylinder due to long-term use."

[0004] However, in the above-mentioned device, the inlet and outlet of the drying filter and the shell are integrated into one, and the interior of the drying filter cannot be inspected after disassembly. Moreover, after long-term use, dust, dirt and impurities will accumulate on the surface of the filter, causing the filter to be clogged, affecting the filtering effect and flow handling capacity. Moreover, the filter is fixed to the inner wall of the dryer and cannot be replaced or disassembled separately, which increases maintenance costs and time. Utility Model Content
