Shenhai Explosion-Proof
Many prospective buyers of explosion-proof air conditioners often grapple with the challenge of selecting the most suitable model amidst a plethora of options available in the market. Let’s delve into the nuances of choosing the right explosion-proof air conditioner, aiming to provide some guidance for your decision-making process.
1. Variety of Explosion-Proof Types
An explosion-proof air conditioner, by virtue of its distinct structure and functionality, is inherently a composite of various explosion-proof types rather than a singular form. For instance, the designation Exdibme IIBT3 incorporates multiple types like the flameproof “d”, intrinsic safety “i”, encapsulation “m”, and increased safety “e.
2. Hazardous Location Categories and Ignition Temperatures
The selection of an explosion-proof air conditioner hinges on the principles of choosing suitable explosion-proof electrical apparatuses:
1. The application zone is determined based on the minimal explosion-proof type. For example, an air conditioner marked Exdibme IIBT3 is appropriate only for Zone 1 or 2.
2. In environments with multiple gases, the choice should be based on the highest category of the electrical equipment and the lowest temperature group. If pentane (IIA, T3) and ethylene (IIB, T2) are potential hazards, the air conditioner should conform to the IIBT3 specification.
Cooling and Heating Capacity Parameters
The selection of cooling and heating capacities, along with the type (wall-mounted, cabinet, or built-in), should be determined by considering the size of the area, its insulation properties, any existing heat sources, and the specific installation requirements of the air conditioner.
