The Heating, Ventilation, and Air Conditioning (HVAC) system filters indoor air for dust, allergens, dirt, and other pollutants. It cleans the air and maintains the temperature at a comfortable level, thereby improving Indoor Air Quality (IAQ). That’s why it has a widespread application in commercial buildings, IT parks, shopping malls, hospitals, schools, and other commercial and industrial spaces. According to a report by Expert Market Research, the global HVAC market is projected to reach USD 301 billion market size at a CAGR of 4% by 2027.
However, the COVID-19 pandemic has put a question mark on the usage of HVAC. Centers for Disease Control and Prevention (CDC) states that SARS-CoV-2 (the virus that causes COVID-19) spreads faster indoors than outdoors. Various studies show that the HVAC system can be an origin of airborne infections in an indoor environment. It can be a breeding ground for pathogenic microorganisms. It can trap airborne particles inside the ductwork and air system. Hence, the HVAC system could be responsible for droplet, aerosol, and airborne transmission which are considered the most common methods of COVID-19 spread.
It becomes imperative that the HVAC system addresses these challenges by not only purifying the indoor air but also decontaminating or inactivating the harmful pathogens which grow within the HVAC system, thereby reducing the pathogen load circulating within indoor spaces.
Ultraviolet Germicidal Irradiation (UVGI) is an electromagnetic radiation technique. According to the American Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE), UVGI uses short-wave ultraviolet energy to inactivate viral, fungal, and bacterial organisms so that they are unable to replicate and cause disease potentially.
UVGI is now considered an effective technique for air disinfection. Hence, it has also found its application in the HVAC system. Unfortunately, the conventional HVAC system is not equipped with UVGI.
1. Improves IAQ and Air Flow
UVGI reduces the buildup of pathogens and contaminants in HVAC. As a result, both heat exchange and airflow improve. It also disinfects and purifies the air, thereby improving IAQ and providing cleaner, healthier air.
2. Gives Higher Energy Efficiency
UVGI lowers the energy consumption of HVAC by restoring its performance to peak level without exhausting itself. This in turn gives higher energy efficiency and you can save money on utility bills.
3. Reduces Disease Transmission
UVGI destroys or inactivates microorganisms such as viruses, bacteria, yeast, mold, and other airborne pathogens which often cause respiratory and other health issues. Several studies have also found that UVGI can kill more than 99.9% of COVID-19 viruses present in airborne droplets and surfaces. Moreover, it is a chemical-free technique and doesn’t leave any residues. Overall, UVGI can be instrumental in reducing diseases transmission through HVAC.
4. Reduces Maintenance
Cleaning of HVAC is a manual process through the use of harsh chemicals. These chemicals are a den of microbial growth and release VOCs (volatile organic compounds) which may cause health issues. UVGI keeps HVAC coils clean year-round. It eliminates the need for routine cleaning and maintenance. Thereby, it also reduces your maintenance cost and is a damage free method where coils are concerned.
5. Improves Well-Being of Staff and Customers
Cleaner and healthier air means that your staff and customers are at a lesser risk of contracting airborne diseases. They will also experience less fatigue. The productivity of your staff will increase and respiratory illness-related absenteeism will decrease.
UVGI is a specialized technology requiring expertise in designing, manufacturing, application and installation. You need a reliable and experienced partner such as Alfaa UV to upgrade your HVAC with UVGI.
Alfaa UV’s Ultra Coil and Ultra Duct UVGI systems use world-class UVC lamps and unmatched Reflector Technology with UL Certification to ensure that all air passing through the system is disinfected as it re-circulates in indoor spaces. The design ensures 100% exposure of the air to the UVC system. The UltraCoil UVGI system not only fights viruses to create safer spaces, but it also ensures cleaner cooling coils, resulting in greater efficiency and lower running and maintenance costs.
