Definition of Lingdu Cabinet Air Conditioning

The definition of cabinet air conditioning is a device that can regulate the temperature, relative humidity, and flow velocity of the air inside the electrical control cabinet. The difference between cabinet air conditioning and ordinary air conditioning lies in their structure, the objects they serve, and the usage environment.

The service objects of cabinet air conditioners are mainly electrical and mechanical equipment.

Electrical equipment usually generates heat due to the action of current during operation, and high temperature can affect the service life and reliability of electrical components, and cause premature aging of insulation devices or a decrease in insulation value, resulting in increased resistance and heat generation of some conductors, and ultimately burning out. Usually, electrical components are labeled with the highest operating temperature or different performance corresponding to different temperatures.

The objects served by cabinet air conditioners are electrical, electronic, or mechanical components, not humans. Therefore, their set temperature can be set very high, between 30 ℃ and 45 ℃, with a default temperature of 35 ℃. In addition, electrical components have no requirements for wind speed or noise. In fact, larger air circulation inside the cabinet can reduce the local heat island phenomenon of electrical components and help with their heat dissipation. In addition, except for outdoor cabinets, the vast majority of other cabinets are installed indoors, and some production environments are relatively complex, with harsh conditions such as high temperature, high humidity, high dust, and even oil or corrosive gases. Especially high temperature and high dust phenomena are relatively common. The working environment temperature of cabinet air conditioners is usually above 42 ℃, with a maximum of 70-80 ℃, and they must meet the following level requirements: such as being able to work continuously for 24 hours, being more robust than civilian products, and having a wider range of voltage requirements. This also requires cabinet air conditioners to meet the reliability requirements for use in this complex environment.

There are usually two cooling methods for cabinet air conditioners: vapor compression and semiconductor cooling, as well as a compressed air vortex tube cooling method.
