Nitin Sreedhar During a recent webinar on the importance of indoor air quality in the times of covid-19, Liam Bates, founder of air quality monitoring and solutions company Kaiterra, summed up the current conundrum when it comes to air-conditioning systems. “HVAC (heating, ventilation and air conditioning) is like a double-edged sword.
It can be your best friend or it can be your worst enemy,” Bates said. “The key here is ventilation.”If your building’s HVAC unit takes the air from a room, cools it down or heats it up, and then mixes it with a little amount of outside air before redistributing it, that is not great news.
