Explosion-proof air conditioning is a general air-conditioning modification. Generally, the air conditioners will be selected from several major domestic brands. Some brands have advantages. Some of them will not be modified afterwards. Air-conditioning is an IIC-class split-type explosion-proof air-conditioning system that uses integrated explosion-proof skills and is manufactured according to industrial environment requirements. It can be used for temperature adjustment, humidity conditioning, dehumidification, humidification and fresh air conditioning in closed or non-closed risk areas. The products must conform to the mandatory specifications GB3836.14 and GB3836.15. They can be used in Zone 1 or Zone 2. They can be widely used in petroleum, chemical, mine, pharmaceutical, aerospace, military and other parts with the IIC level. The temperature group is Zone 1 (or Zone 2) risk location for explosive gas mixtures in Group T4. The main features of explosion-proof air-conditioning products are as follows: 1. Explosion-proof air conditioners should use integrated explosion-proof skills, use special micro-electronic skills, large-scale integration and simplify explosion-proof structure, and the product explosion-proof grade is IIB T4. The product is small in size, light in weight, and the same size as the non-explosion-proof air conditioner of the same type. There is no external explosion-proof junction box.
General explosion-proof air conditioners are divided into: indoor unit with ceiling type, wall type, cabinet type, combined type, which can supply users with constant temperature and humidity, duct type, with fresh air equipment and brand new air conditioner and modular combined central air conditioner (per Each module can supply 5~10 cooling capacity); together, it can supply users with high temperature type, low temperature type, corrosion resistance and marine use. In the meantime, the wind curtain type indoor model has the function of blocking the risk gas to build a safe air curtain safety space, which can solve various industrial use problems. Users can choose indoor and outdoor machines according to the requirements of practical use to form various explosion-proof air conditioning systems;
Second, the control circuit should use micro-watt level all-optical isolation substantial safety circuit, its safety factor is more than three orders of magnitude higher than the world-recognized safety energy coefficient.
Third, the use of imported compressors with low surface temperature to meet the requirements of T4 temperature group <135>135>
Fourth, the use of high surface temperature limit maintenance skills and a variety of safety maintenance skills.
5. The airtight enclosure of the refrigeration system is selected for leak detection and maintenance of positive pressure type composite explosion-proof structure, so that the explosion-proof function meets the new mandatory safety regulations and can be used in Zone 1.
Sixth, choose a comprehensive anti-static skills. General explosion-proof air conditioners cannot be used in the above environment, and can only be used in households or in an environment without explosive gas!
