Alfaa UVGI Solutions For HVAC Industry – A powerful step to fight COVID-19 in air-conditioned spaces

Posted on August 25, 2020 Alfaa UVGI Solutions For HVAC Industry – A powerful step to fight COVID-19 in air-conditioned spaces

As communities and businesses across the country begin to reopen, more people are weighing whether—and how—they should head into work and, perhaps, visit malls and schools. This global pandemic has changed the way humans live, and hence the adoption of new technologies is obvious. There is growing evidence today that COVID 19 viruses hang as microscopic droplets in the air and infect the person breathing in that air. As a result, various guidelines and research papers related to systems that can help in diminishing the spread of Coronaviruses have been released, and HVAC systems are one of them. There are three main ways to get rid of airborne pathogens in building interiors. Pathogens can be expelled from the building with exhaust fans, they can be captured with high-performance air filters, or they can be killed with air purification methods. ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers.) strongly recommends the use of Ultraviolet Germicidal Irradiation or UVGI, which is effective against viruses, bacteria, and mould spores.

Research has shown that places like shopping malls, hospitals, commercial spaces, IT Parks, and schools are exposed to similar unhealthy environments, and that can heighten health issues including congestion, headaches, upper respiratory tract ailments, flu and the novel coronavirus which is responsible for the COVID -19 pandemic.

The use of UVC Rays

UVC rays of 254nm wavelength kill germs effectively without chemical cleaning, steam injections, or other harsh methods. UVC rays disrupt the reproduction cycle of germs by attacking their DNA. It is a completely safe, environment-friendly, and efficient way to remove mould, viruses,  bacteria, and fungi from coils and drain pan surfaces of air handling units.

Advantages

  1. Eliminates up to 99.9% of mould spores and kills up to 87% of certain airborne pathogens passing through the air system
  2. Maintains system efficiency and airflow, which saves money by not having to have your system coils cleaned as often
  3. Increases productivity and helps reduce absenteeism due to illness
  4. Highly recommended by many credible organizations like the US Government and the Air Institute of Respiratory Education, for killing microbes and improving Indoor Air Quality.

Some businesses are planning to bring back only a portion of workers to the office or are instituting shifts to allow for social distancing. However, this may not mitigate the spread of the novel coronavirus in airconditioned spaces. Installation of germicidal UV light for HVAC will definitely curb the spread of the Coronaviruses. Airborne contamination comes from a variety of sources and circulates majorly through the HVAC system. In-duct ultraviolet germicidal irradiation (UVGI) systems treat moving airstreams in heating, ventilation, and air-conditioning(HVAC) systems by inactivating airborne microorganisms found within. Airborne transmission of diseases through HVAC systems is much more prevalent nowadays than previously encountered.

Introducing UltraCOIL by ALFAA UV

Alfaa UV’s ULTRACOIL ensures deep cleaning of coils in the safest and most eco-friendly way. There is no worry about the damaging of coils, which is highly likely with conventional chemical and scrubbing methods. The Ultracoil with its unique Parabolic Reflector System proactively removes the bio-films (layer of slimy, sticky substance that houses the bacteria, viruses, mould, spores, etc.), thus ensuring that the air does not get contaminated through the coil and drain pans.

Installing a proper UVGI air disinfection system in front of the coil kills such microorganisms and viruses (Coronaviruses as well), hence disallowing the formation of a biofilm. A clean coil decreases the pressure drop across itself, which results in the following;

  1. Increase in the thermal efficiency (sensible loads) of the cooling coil.
  2. Decrease in the load on the chiller – hence saving energy on chiller by 10-15%.
  3. Reduction in microbial counts >15 %.
  4. Increasing the life of a coil by avoiding manual cleaning.
  5. Earning IGBC (Indian Green Building Council) points.

UltraDUCT by ALFAA UV

Airborne contamination comes from a variety of sources and circulates majorly through the HVAC system. In-duct ultraviolet germicidal irradiation (UVGI) systems treat moving airstreams in heating, ventilation, and air-conditioning (HVAC) systems by inactivating airborne microorganisms found within. Airborne transmission of diseases through HVAC systems is much more prevalent nowadays than previously encountered.

Alfaa UV’s ULTRADUCT solution provides assured single pass disinfection of airborne bacteria and viruses. It is installed in supply or return ducts. The Ultraduct also increases the life of HEPA (High-Efficiency Particulate Air) by reducing the load of live organisms. There are various benefits of installing ULTRADUCT in HVAC systems, some of which are listed below:

  • Improves air quality.
  • Helps in eliminating Sick Building Syndrome. Read this blog to know why working professionals should care about indoor air quality.
  • Increases the life of HEPA.
  • Helps in eliminating cross-contamination.
  • Scientifically designed systems are sized using our proprietary sizing tools based on extensive research.
  • Computational flow dynamics (CFD) and UV radiation profile modeling details used to make the system highly efficient and effective.
  • Scientifically engineered positioning of UV lamps for air disinfection ensures delivery of optimum UV dosage and maximum efficiency in killing microorganisms.
  • Can target specific bacteria as per requirement.
