“In many cases, an HVAC system must be specially built and use a combination of explosion proof, intrinsically safe and non-incindive equipment to address flammable or ignitable substances, and it may also require integrated chemical filtration systems to prevent corrosive and toxic substances from being recirculated or introduced to a room or building from what would otherwise be considered as a fresh air or make-up air source,” said Baucom, who wrote the recently released ASHRAE Guide for HVAC in Hazardous Spaces.
Explosion-proof HVAC/ Pressurized Air Conditioning Units are mainly composed of explosion-proof integral air-conditioning units, air ducts, explosion-proof dampers and explosion-proof control boxes. The unit introduces the air in the cabin into the air conditioning system through the air duct for circulation, and supplements fresh air from the safe area to ensure the normal positive pressure value in the analysis room. The unit mixes the return air with the fresh air and processes it into comfortable air and sends it into the analysis room, and ensures that the positive pressure range in the room is between 25-75Pa (adjustable).
