commercial HVAC (heating, ventilation and air conditioning) System has the same objective as a residential HVAC system – to keep the building occupants cozy with high quality air in a 72-degree environment, the humidity ranging from 40 to 60 percent.
The heating of air is often achieved through burning fuel (gas, oil, electricity). Cooling the air is the opposite (naturally), with a process that extracts hot indoor air and cools it through refrigerant or water-cooled systems, eliminating the extra humidity at the same time.
Ventilation systems use fans to introduce the necessary outside air, pass both the outdoor and re-used indoor air through filtration, and expel the building’s contaminated air. This keeps the CO2 at under 1000 molecules per million.
An effective ventilation system reduces odors, dilutes gases (like carbon dioxide) and prevents respiratory diseases from spreading.Without it, unwanted particles would render the air stale and increase mold and mildew growth.
