As an indispensable part of the refrigeration system, the filter dryer plays a vital role in ensuring the stable operation of equipment. It cleverly integrates the two core functions of drying and filtering, as if a double protective net is installed for the refrigeration system. In terms of drying, the internal is filled with molecular sieve or activated alumina, and another efficient desiccant can accurately capture and absorb the residual water in the refrigerant circulation process, effectively prevent the phenomenon of ice blockage caused by excessive water, and avoid equipment failure caused by ice blocking pipes. In the filtration process, the precision design of the multi-layer filter structure can layer on the refrigerant metal debris, dust, oxide,s and other impurities, to ensure the pure flow of refrigerant, to protect the compressor, capillary, and other core components from wear and corrosion. With the dual advantages of high efficiency moisture absorption and precision filtration, the filter dryer significantly extends the service life of refrigeration equipment, and provides stable and reliable operation guarantee for various refrigeration scenarios such as air conditioning, refrigerators, and cold storage.
During the operation of the refrigeration system, harsh working conditions are often an important factor leading to equipment failure. As a key component to ensure the stable operation of the system, the durability and corrosion resistance of the refrigeration filter drier in harsh environments are crucial. To ensure that the refrigeration filter drier maintains good performance under such conditions, comprehensive considerations need to be made from multiple aspects.
Material selection is the basis
Under harsh working conditions, the refrigerant filter drier faces the test of various complex factors, and the choice of materials is directly related to its durability and corrosion resistance. For the shell material, stainless steel materials such as 304 or 316 stainless steel can be selected. 304 stainless steel has good corrosion resistance and can work stably in general humid and slightly corrosive environments; 316 stainless steel has stronger corrosion resistance due to the addition of molybdenum, especially in harsh environments such as chloride ions.
The choice of internal filling materials is also critical. Desiccant can be made of high-performance molecular sieves or activated alumina, which not only have strong moisture absorption capacity, but also can resist the influence of corrosive substances to a certain extent. The filter material can be multi-layer metal mesh or high-precision filter material. These materials should have good strength and corrosion resistance, can effectively block impurities, and are not easily damaged in harsh environments.
Structural design is the key
Reasonable structural design can effectively improve the performance of the dry filter under harsh conditions. The structural design of the shell should take into account the pressure resistance and impact resistance, and maintain the integrity of the structure when facing pressure changes or possible mechanical shocks in harsh environments. For example, a thickened shell wall or a reinforced structural design can be used to increase the strength and rigidity of the shell.
The internal filter structure design should not be ignored. The reasonable layout of the multi-layer filter structure can make the impurities in the refrigerant more fully filtered. At the same time, it is necessary to consider the situation that impurities may increase under harsh conditions, design a reasonable filter area and flow rate, and avoid affecting the filtration effect and the durability of the equipment due to excessive filtration burden. Zhejiang Jinhao Refrigeration Equipment Co. Ltd has a strong technical team that can provide solutions according to customer needs, and can combine the actual use of the structural design to provide users with better solutions.
Surface treatment to enhance protection
Special treatment of the surface of the dry filter is an effective means to enhance its corrosion resistance. Common surface treatment methods include electroplating and spraying. Electroplating can form a uniform coating on the metal surface, such as zinc plating, chrome plating, etc. These coatings can effectively isolate the metal from the contact with the external corrosive medium and improve the corrosion resistance. For spraying, you can choose corrosion-resistant coatings, such as epoxy resin coatings, fluorocarbon coatings, etc., and spray them evenly on the surface of the shell to form a solid protective layer.
When performing surface treatment, it is necessary to ensure the quality of the treatment process to avoid problems such as uneven coating and bubbles, otherwise it will affect the protection effect. Zhejiang Jinhao Refrigeration Equipment Co. Ltd follows the principle of continuous technological updating and can apply the latest surface treatment technology to products to provide better protection for dry filters.
Strict manufacturing process control
The quality of the manufacturing process directly affects the durability and corrosion resistance of the dry filter. In the production process, the process parameters of each link must be strictly controlled. For example, the welding process must ensure that the welding is firm, there is no false welding, and there is no crack, so as to avoid weak points of leakage or corrosion of the shell due to welding problems. For the filling of internal filling materials, it is necessary to ensure that the filling is uniform and tight to avoid gaps that affect the drying and filtering effects.
At the same time, a strict quality inspection system should be established to inspect each process to ensure that the product meets the quality requirements during the manufacturing process. Zhejiang Jinhao Refrigeration Equipment Co. Ltd, as a manufacturer with a full range of products in the domestic refrigeration industry, has strict control over the manufacturing process, which also ensures the performance of its products under harsh conditions.
Reasonable maintenance and care
Even if the dry filter has good durability and corrosion resistance, reasonable maintenance and care are essential under harsh working conditions. Check the dry filter regularly to see if the outer shell is corroded or damaged, and whether the internal filling material needs to be replaced. According to the actual use, formulate a reasonable replacement cycle, replace the aging desiccant and filter material in time, and ensure the performance of the dry filter.
Zhejiang Jinhao Refrigeration Equipment Co. Ltd has a special technical training department, where technical experts and service engineers provide customers with relevant basic knowledge and practical experience, and provide users with detailed design plans, product technical performance parameters, layout plans, budget analysis reports based on the actual use of customers, which also includes maintenance and maintenance guidance to help customers better use and maintain the refrigerant filter drier.
Special design to adapt to harsh environments
Special designs can also be made for different harsh working conditions. For example, in a high humidity environment, the filling amount and moisture absorption capacity of the desiccant are increased; in an environment containing corrosive gases, a higher level of corrosion-resistant materials and more complete surface protection measures are used. For environments with drastic temperature changes, the thermal expansion and contraction properties of the material should be considered to avoid structural damage due to temperature changes.
