Air Economizers Impact Indoor Air Quality Amid Pollution Events, Study Finds
SALT LAKE CITY — A recent study by The University of Utah has shed light on the effects of air economizers in HVAC systems on indoor air quality, particularly under specific pollution conditions like wildfire smoke and seasonal inversions. Kerry Kelly, Associate Professor of Chemical Engineering, noted that residents of Salt Lake City often encounter various pollution events that significantly affect air quality indoors.
Air economizers, commonly found in commercial buildings, are designed to enhance energy efficiency by drawing in outdoor air during favorable weather conditions. However, Kelly emphasized that while these systems save energy, they can also inadvertently introduce pollutants into indoor environments, especially during events like wildfires.
To monitor indoor air quality, Kelly recommends using particulate matter sensors, which provide a relative measure of pollution. She also advocates for portable air filters, noting that simple filtration devices can be remarkably effective in mitigating indoor air pollution.
With the ongoing challenges posed by environmental pollutants, understanding HVAC systems’ roles is crucial for maintaining a healthier indoor atmosphere.
