When it comes to COVID-19 and HVAC systems, there are a lot of unknowns. Businesses hope to avoid the spread of the coronavirus among employees as much as possible. But how?
There are various ways that HVAC systems play a part in curbing the current global pandemic. Consider these COVID-19 HVAC questions and answers to help you make the right decisions for your business.
Can HVAC Systems Help Prevent the Spread of COVID-19?
Proper ventilation is pivotal in slowing the spread of viruses, including COVID-19. HVAC systems circulate air and reduce humidity, which prevents the virus from being able to live in the air. Heavy, moist air will hold more pathogens as the moisture gives them something to cling to. HVAC systems bring fresh outdoor air into the building and push stale indoor air out. Viruses can’t live in the open air long enough to be passed through the HVAC and infect anyone.
How Does UV Light Kill Viruses?
UV lights have the capability to destroy viruses. This is not new information, as scientists have been aware of this for decades. Wavelengths between 200 and 400 nanometers are the most effective. The way it works is that the ultraviolet light breaks apart the virus by destroying the bonds that hold it together (mostly hydrogen). The virus can’t survive and cannot infect anyone once it is dead.
While it can help to kill viruses, a UV light alone is not capable of completely eliminating COVID-19 from a building. The EPA (Environmental Protection Agency) recommends the use of UV light in conjunction with best practices recommended by the CDC (Center for Disease Control).
Is UV Light Safe for People?
UV light is radiation. This is why UV rays from the sun can cause skin cancer. Which begs the question, can UV light be harmful to people? And if so, should it be used in businesses around many people?
UV lights are installed deep in the HVAC system where the light itself, the radiation, will not come in contact with people. It is out of sight and only shines on the air as it passes through the HVAC ducts, meaning it cannot harm people. Professional HVAC technicians know how to carefully handle these UV lights to avoid exposure to radiation themselves.
How Can I Get a UV Light Installed in My Commercial HVAC System?
A commercial HVAC company can install UV lights at various points in your HVAC system to ensure the optimal amount of virus control. The size of your building and other factors will affect the placement and number of UV lights you’ll need to get the most virus protection possible.
