According to the United States Environmental Protection Agency (EPA), "Americans, on average, spend approximately 90 percent of their time indoors, where the concentrations of some pollutants are often 2 to 5 times higher than typical outdoor concentrations." In some instances, individuals can spend even more time in their home and have above average indoor air quality concerns.
Indoor air quality issues can come from an array of sources such as a lack of fresh air, chemical usage and dirty air filters to name a few. With Venthalpy technology, the sources that are both visible and invisible to the naked eye can now be identified for proper air quality optimization.
Volatile Organic Compounds (VOC's) are chemicals that are emitted into the air from various sources such as cook-tops, candles, household cleaners, etc. They contain compounds such as benzene, butanal, formaldehyde and acetone that are harmful to the human body and can destroy some types of indoor HVAC coils. Venthalpy measures the levels in the space so an assessment can be made on the source and how to remedy the issue.
A topic often not discussed in the HVAC industry is the blower speed's influence on the indoor air quality. Blower speed directly affects the relative humidity of the conditioned space. When the speed is too low, body irritations and the building's structural integrity can be compromised. When too high, mold and bacterial growth can quickly lead to a poor breathing environment. Venthalpy outputs to the HVAC technician real-time a recommended blower speed setting based on the outdoor and indoor environment conditions to optimize humidity control.
If the inside of any duct work sweats just one time, there can be enormous health concerns. Venthalpy identifies if the duct work is at risk of sweating on every use and gives recommendations on why the duct work is sweating or approaching the range of sweating. This feature should drastically reduce the number of duct runs that have been compromised with various types of organic growth.
