An added benefit of working economizers is that they bring “Free” Cooling into the building during Spring & Fall, when outdoor air conditions allow. By utilizing cool ouside air, the system does not need to mechanically cool the air before circulating in the indoor space (provided temperature and humidity is within desired system range). While “Free” Cooling is an added benefit during Spring and Fall, economizers are useful 365 days per year. They can always be used year round to bring in a desired, predetermined percentage of fresh outside air into the building’s occupied indoor space. And fresh outside air is not only a critical component for combating COVID19, it also provides general benefits to building occupants overall health and productivity.
Enhancing Indoor Air Quality within buildings has been recommended by ASHRAE and government agencies as an effective method to combat COVID19 within occupied indoor spaces. The two easiest ways to accomplish this are through Filtration & Dilution:
. In this email, we will focus on Building Ventilation / Dilution and its associated benefits. Building Ventilation utilizes the Economizers in an HVAC system to introduce more fresh air to be pulled into the building.
This new introduction of fresh air dilutes the existing indoor air in the building space, thereby reducing the concentration of any existing airborne contaminants.
In order to take advantage of these Ventilation benefits, we must first verify the following:
If your equipment has economizers, now is the time to make sure they are fully operational so that you can take advantage of the benefits listed above.
