Cabinet air conditioners are widely used in various fields such as data processing, communications, finance, metallurgy, petrochemicals, building materials, automobiles, military industry, etc., and are also called industrial air conditioners. This often appears in industrial design. At present, our cabinet air conditioners are also widely used in some large data processing centers and CNC machining centers. The excellent effects and excellent performance of cabinet air conditioners are recognized and used by more and more people.

The internal components of the control cabinet are dense and have a large heat output. There are more and more system failures, equipment shutdowns, and high-temperature alarm phenomena caused by poor heat dissipation and excessive temperature rise. The traditional cooling method is to use cooling fans for cooling, which not only has poor heat dissipation effect, but also allows dust and corrosive gases to enter the cabinet. Cabinet air conditioners can effectively reduce the internal temperature of the control cabinet and prevent dust, moisture and corrosive gases from entering the internal of the control cabinet. It is suitable for the temperature and humidity control of electrical control cabinets and computer (server) cabinets with high reliability requirements and is a powerful guarantee for the reliable operation of the electronic control system.

Cabinet air conditioners are devices that can adjust the temperature, relative humidity and flow speed of the air inside the electrical control cabinet. Cabinet air conditioners are different from household air conditioners, and the two have different uses. The objects served by cabinet air conditioners are mainly electrical and mechanical equipment. Electrical equipment usually generates heat due to the action of current during operation, and excessive temperature will affect the service life and reliability of electrical components, and will prematurely age insulation devices or reduce insulation values, making the resistance of some conductors increase, generate heat and then burn out. Usually electrical components will indicate the maximum operating temperature or different performances corresponding to different temperatures. Household air conditioners serve people and are usually installed in rooms, indoors, restaurants, etc., to cool large spaces. The objects served by cabinet air conditioners are electrical, electronic or mechanical components, not people. Therefore, their set temperature can be set very high, between 30°C and 45°C. The default temperature is generally 35 °C, and electrical components have no requirements for wind speed and noise. In fact, larger air circulation in the cabinet can reduce the local heat island phenomenon of electrical components and contribute to the heat dissipation of electrical components.
