Description

Technical Field

[0001] The utility model relates to the technical field of drying filters, in particular to an air-conditioning refrigeration drying filter. Background Technique

[0002] In modern refrigeration systems, especially in air-conditioning systems, drying filters play a crucial role. Their main function is to filter impurities in the refrigeration cycle, such as metal chips, oxides, dust, etc., and absorb moisture in the refrigerant and lubricating oil to prevent these impurities and moisture from damaging key components of the system, such as compressors, capillary tubes, expansion valves, etc. However, the traditional design of drying filters often has the problem of inconvenient replacement of desiccants, which brings many challenges in actual application and maintenance processes.

[0003] Traditional drying filters usually adopt an integrated design. Once the desiccant (such as molecular sieve or activated alumina) filled inside absorbs moisture to saturation, the entire filter needs to be replaced as a whole. This not only increases the maintenance cost but also may lead to a relatively long system downtime, affecting the normal use of users. In addition, since the replacement of the desiccant requires professional technicians to operate and the operation process is complex, this also increases the difficulty and risk of maintenance. Therefore, we provide an air-conditioning refrigeration drying filter for use. Content of the Utility Model
