Ultraviolet (UV) light has been growing as part of the HVAC landscape for years, specifically within the IAQ arena. ASHRAE's validation is certainly a huge step forward for UV, but many manufacturers believe this technology has already proven its value, as its growth and expansion began years ago.

Whether it’s through the use of UV light, whole-home IAQ solutions, or commercial-grade air-filtration equipment, the following case studies showcase ways contractors have solved IAQ problems at both the residential and commercial levels.

Nearly 61,000 HVAC industry representatives enjoyed sun and reasonable temperatures as the 2016 AHR Expo rolled into Orlando, Florida. Preliminary numbers show that more than 18,254 exhibitor personnel welcomed 42,672 visitors.

HVAC contractors are constantly seeking accurate, energy-efficient, year-round solutions to their customers’ humidification and dehumidification needs. A number of those solutions were on display at the 2016 AHR Expo in Orlando, Florida. 

Manufacturers are addressing this demand head-on by creating and adapting products that are accessible to both contractors and consumers with an eye toward digital displays and functions that can be updated and expanded in the years to come.

Ultraviolet germicidal irradiation (UVGI), according to the U.S. National Library of Medicine, National Institutes of Health, is an established means of disinfection and can be used to prevent the spread of certain infectious diseases. UV-C radiation kills or inactivates microbes by damaging their DNA.

The RecoverAire product provides energy recovery for indoor pool room exhaust applications. 

The product delivers ultraviolet energy to destroy coil/drain pan microbial infestations and disinfect moving airstreams in hard-to-service fan coil units, package terminal air conditioner (PTAC) units, and heat pump systems. 

This IAQ monitor has an auto-zero function and takes measurements with accuracy in a simple design.
