Air-conditioning units required in the chemical industry are refrigeration equipment designed to provide cooling and temperature control for the reliable operation of industrial production processes or industrial process equipment. In the chemical industry, it is often necessary to cool acid-alkali tanks or chemical reactors. However, chemical tanks and their surrounding air environments contain large amounts of chemical liquids and gases. If these chillers are not properly treated, they can corrode the chiller’s components. Due to the special operating conditions of products in the chemical industry, product design faces numerous challenges, thus requiring consideration of many factors. Specifically, these units can be applied as explosion-proof special-purpose refrigeration units.

Pharmaceutical industry

Ultra-low temperatures ranging from -50℃ to -100℃ are primarily used in fields such as food processing, petrochemicals, biopharmaceuticals, and scientific research. In recent years, the applications of ultra-low temperatures have become increasingly widespread, making ultra-low-temperature refrigeration cycles, auxiliary refrigeration equipment, and refrigeration system design for ultra-low-temperature applications particularly important. Medical refrigerators are one such example. Medical refrigerators are widely used in hospitals, and some households also keep them on hand for storing medications and other pharmaceutical products. Medical refrigerators are mainly used to preserve special drugs, vaccines, enzymes, hormones, stem cells, and other critical biological and chemical reagents—these specialized pharmaceuticals are not only used in major hospitals but also in numerous medical research settings. Specifically, they can be applied to equipment such as ultra-low-temperature freezers and refrigerators.

Laser processing technology is a manufacturing technique that leverages the interaction between laser beams and materials—including both metals and nonmetals—to perform operations such as cutting, welding, surface treatment, hole drilling, and microfabrication. As an advanced manufacturing technology, laser processing has been widely adopted in key sectors of the national economy, including automotive, electronics, electrical appliances, aerospace, metallurgy, and mechanical engineering. It plays an increasingly important role in enhancing product quality, boosting labor productivity, promoting automation, minimizing pollution, and reducing material consumption. Laser cutting produces edges free of burrs and wrinkles, with high precision—qualities that outperform plasma cutting. For many electromechanical manufacturing industries, modern laser cutting systems equipped with computerized programs offer the convenience of cutting workpieces of various shapes and sizes, making them often the preferred choice over traditional methods such as punching or die-casting. Although laser cutting is slower than die-cutting, it eliminates the need for costly tooling, avoids the expense of mold repairs, and saves time on mold changes, thereby lowering overall production costs. Specific applications include integrated laser cutting machines.

Currently, a common issue plaguing both residential and commercial central air-conditioning systems is their relatively high energy consumption. According to relevant studies, although large public buildings account for less than 4% of the total floor area of urban buildings, they consume over 20% of the total electricity used in urban areas nationwide, indicating significant potential for energy savings. Today, major refrigeration equipment manufacturers offer customers multi-level solutions, including electronic expansion valves, variable-frequency drives, and CO2-based systems. They also provide customized solutions tailored to various business formats, suitable for hypermarkets, standard supermarkets, and convenience stores. Specifically, these solutions can be applied to commercial variable-frequency air-conditioning units and mini-condensing units for supermarkets and retail outlets.

What should I do if the high-temperature fault occurs in screw air compressor parts?

Compared to piston-type air compressors, screw-type air compressors have more components—such as sensors, temperature control valves, filters, main controllers, and more. This also contributes to the characteristics of screw-type air compressors.
