Indoor Air Quality has been an issue for enclosed spaces, homes, office buildings, medical facilities and industrial buildings since the early 70’s. The issues of people suffering from a wide range of health issues, mostly respiratory in nature, became more acute once the building industry started to build tighter buildings that offered little or no outside air intrusion. This process reduced the energy costs, but increased the amount of stale air and concentrations of gaseous pollutants and airborne particulate that are generated from most materials, chemicals, plants, animals and manufacturing processes.
Using only recirculating air through the air handlers and HVAC units and not allowing any outside, fresh air increased the IAQ issues. Adding outside air only added to the amount of particulate already present in the occupied space.
Pure Air Systems, based in Indiana, had developed a variety of commercial grade, fan powered, HEPA filter systems that could be used to both filter the air in the space as well as add small amounts of filtered outside air. By only adding 50 CMF to 100 CFM of outside air through the PAS units, one air handler could introduce up to 6,000 CFM of fresh, filtered outside air every hour and adding that to the recirculated air also being filtered, created a much healthier environment and reduced the amount of headaches, and respiratory issues in most residential and commercial operations.
Adding the small amounts of outside air, even on hot and very cold days, had a minimal affect on the amount of energy required to heat and cool the indoor environment. By adding an actuator to the inlet damper, it is possible to modulate the amount of outside air so that more or less air could be introduced depending upon weather or the conditions in the occupied space.
