DOAS air handling unit with heat recovery wheel and passive dehumidification. A dedicated outdoor air system (DOAS) is a type of heating, ventilation and air-conditioning system that consists of two parallel systems: a dedicated system for delivering outdoor air ventilation that handles both the latent and sensible loads of conditioning the ventilation air, and a parallel system to handle the ...
Open-air treatment is the therapeutic use of fresh air and sunshine. In a hospital or sanitorium , this may be done by ensuring good ventilation in an airy, sunny room or by housing patients outdoors in tents or other open forms of accommodation.
Unlike air purifiers, which filter or otherwise trap particles within an air circulator, air sanitizers act on airborne microorganisms in open interior air space. A sneeze - or cough -generated pathogenic aerosol will take significant time to be treated by a circulating air purifier simply because air circulators are unable to treat all air in ...
The result (in theory, anyway) is a fire pit that promotes better air flow and a much hotter burn to reduce the amount of smoke given off. Solo Stove fire pits are also known for their durability ...
Underfloor air distribution (UFAD) is an air distribution strategy for providing ventilation and space conditioning in buildings as part of the design of a HVAC system. UFAD systems use an underfloor supply plenum located between the structural concrete slab and a raised floor system to supply conditioned air to supply outlets (usually floor ...
Cross ventilation is a natural phenomenon where wind enters an opening, such as a window, flows directly through the space, and exits through an opening on the opposite side of the building (where the air pressure is lower). This produces a cool stream of air and a current across the room from the exposed area to the sheltered area. [1]
The Nash "All-Weather Eye" was the first automobile air conditioning system for the mass market. [2] The use of the Weather Eye name for automobile passenger heating and air conditioning systems continued in American Motors Corporation (AMC) vehicles. The design principles of the Nash Weather Eye system are now in use by nearly every motor ...
Free cooling is an economical method of using low external air temperatures to assist in chilling water, which can then be used for industrial processes, or air conditioning systems. The chilled water can either be used immediately or be stored for the short- or long-term. When outdoor temperatures are lower relative to indoor temperatures ...
