Filtration, dehumidification, humidification, special considerations for special environments … anything and everything that pertains Indoor Air Quality, breathing easier, working better, or protecting contents.
All outside air isn’t created equal, neither is the available engineering guidance, and there isn’t enough preliminary owner/consultant discussion about the pros and cons. Welcome to the air filtration design process.
A Tennessee district faced an old school HVAC challenge: aging ventilators and space constraints. So this team tried a new-school variation on common VRF retrofits to deliver improved efficiency and critical IAQ: they decentralized the outdoor air, combining enthalpy wheel and VRF components within a single classroom enclosure.
Revitalizing turn-of-the-century infrastructure means finding a way to dehumidify interiors successfully. Before you move on to weighing DOAS and other techniques, understand the built-in relationship between these structures and water.
