Industrial air conditioning refers to air conditioning equipment that provides environmental temperature, humidity, and cleanliness for the reliable operation of industrial products or industrial process equipment. For example, the constant temperature and humidity control air conditioner used to ensure the normal operation of the electrical control indoor equipment, the high temperature environment special air conditioner used in the mobile bridge crane of the steel making workshop, the low temperature unit air conditioner used in the meat processing workshop, etc. It belongs to industrial air conditioning.
Industrial air conditioners differ from home air conditioners or civil air conditioners in many aspects. Industrial air conditioning belongs to the category of technological air conditioners. Household air conditioners or civil air conditioners belong to the category of comfort air conditioners. Industrial air-conditioning is designed with the main purpose of ensuring process requirements, and the comfort of the indoor staff is secondary.
The power consumption of industrial air conditioners is generally relatively large, ranging from several tens of kW to several thousand kW, and generally uses a 3N~380V 50Hz power supply. Industrial air conditioners are generally designed to operate 24 hours a day, throughout the year, and have a life expectancy of more than 15 years. Therefore, the main components of industrial air conditioners such as compressors, condensers, throttling devices, evaporators, fans, motors, electrical components, etc., all use well-known brands with high performance and reliability.
In terms of manufacturing process, industrial air conditioners generally use all-steel sheet metal structures and panel electrostatic spray paint treatment. Has a high anti-corrosion durability. Industrial air conditioners must perform performance tests before leaving the factory to ensure that they meet design requirements. Shipped to the user, but also through the installation, commissioning and other processes, after successful debugging, the unit was officially put into operation.
