Application Of Explosion-proof Precision Air Conditioner In African Computer Room

Application of explosion-proof precision air conditioner in African computer room

Explosion-proof air conditioners are a kind of explosion-proof electrical appliances, mainly used for refrigeration and heating in flammable and explosive environments such as petroleum, chemical industry, military, oil depots, offshore oil platforms, etc. The appearance and usage of explosion-proof air conditioners are the same as ordinary air conditioners. Explosion-proof air conditioners are divided into high temperature, low temperature, extra high temperature, and extra low temperature according to the working environment.

Explosion-proof air-conditioning products must meet the relevant national explosion-proof standards before they are allowed to enter the market. The current nationally announced implementation standards for explosion-proof products are:

GB3836.1-2000 Electrical Equipment for Explosive Gas Atmosphere Part 1: General Requirements

GB3836.2 -2000 Electrical equipment for explosive gas atmosphere Part 2: Flameproof type "d"

GB3836.4 -2000 Electrical equipment for explosive gas atmospheres Part 2: Intrinsically safe type "ib"

GB3836.9-2006 Electrical Equipment for Explosive Gas Atmosphere Part 9: Encapsulated Type "m"

GB3836.15-2000 Electrical Equipment for Explosive Gas Atmosphere Part 15: Electrical Installation in Hazardous Locations (Except Coal Mines)

Overview of JB/10538-2005 "Explosion-proof Dehumidifier and Air Conditioner"

Explosion-proof air conditioner has cooling and heating and automatic defrosting functions. Compressors, fans, etc. have undergone special explosion-proof treatment. The explosion-proof type is explosion-proof for the whole machine. It can be used in flammable and explosive mixed gas environments such as petroleum, chemical industry, medicine, scientific research, military, and dangerous warehouses. In the structure, it adopts explosion-proof, intrinsically safe, encapsulated and other composite explosion-proof technologies, and the control end is all controlled by intrinsically safe, which does not generate any sparks, and is convenient and safe to use.

Explosion-proof air conditioners maintain the basis of ordinary air conditioners and perform explosion-proof treatment on electrical systems, including compressors, fans, and electrical circuits. The control circuit adopts an electrical system with optocoupler solid-state relays as the core for overall explosion-proof. The original basic functions of the original air conditioner are kept, the structure is simplified, and the operation is simplified, so that the equipment can be used safely in a mixed gas environment.
