Scope: This standard specifies the terms and definitions, types and basic parameters, technical requirements, test methods, inspection rules, marking, packaging and storage of explosion-proof dehumidifiers and air conditioners. This standard is applicable to integral or split structures that use mechanical refrigeration to dehumidify and use condensation heat as reheating method with a nominal dehumidification capacity greater than 0.16kg/h, and are allowed to be used in Class IIA, IIB, T1~T4 groups of flammable gases, steam Explosion-proof dehumidifiers are used in places with explosion hazards caused by mixing with air, and in environments where explosive gas mixtures occur or may occur. This standard also applies to unit air conditioners with a nominal cooling capacity greater than 7000W (excluding automobile, train and marine air conditioners), and allows explosions caused by mixing flammable gases, steam and air in Class IIA or IIB, T1~T4 groups Explosion-proof air conditioners used in hazardous locations and environments where explosive gas mixtures occur or may occur.
