What is Indoor IAQ?
IAQ stands for Indoor Air Quality and refers to the quality of air of our surroundings. It is related to health and comfort of occupants. Understanding and controlling common pollutants in our surrounding air can reduce risk of indoor health issues.
UVC for IAQ
Ultraviolet (UV) is a spectrum of light just below the visible range and is classified into four spectral areas: UV (100 to 200 nm), UVC (200 to 280 nm) UVB (280 to 315 nm) and UVA (315 to 400 nm)
The spectral range of UVC finds its application mainly to inactivate microorganisms, such as bacteria and viruses, by altering the structure and the molecular bonds of their DNA which these organism use to develop, function and reproduce thus rendering them harmless.
For this purpose, UVC lamps provide a concentrated effect of the UV energy and ultimately a highly effective method of destroying microorganisms.
Health Impact Studies have shown that HVAC systems provide conditions that are ideal for growth of bacteria and molds, especially in evaporator coils, drain pans and ducts.
These contaminants have negative health and development effects on your family at home and employees at work. The biological contaminants typically found on HVAC coils and drain pans have also been linked to Sick Building
Syndrome (SBS), hospital acquired infections, headaches, severe allergy and
Mold build-up over 10 years old in AHU insulation & coil
In addition to health impacts, the formation of molds and bacteria on coils leads to significantly excessive energy consumption in the following ways:
1. The mold and bacteria formation on coils acts as a barrier to air flow in the air handling units, leading to higher consumption of fan motor current to achieve the required amount of air-flow.
2. The mold and bacteria also serve as an insulating bio film that decreases heat transfer between the flowing air and the coil in an air handling unit. This leads to the fan running longer to maintain the required space condition. As a chain effect, the chillers and pumps also work in excess to achieve the required space temperature set points.
