Applied/Engineered HVAC

Heating, Ventilation, & AirConditioning (HVAC) is the use of various technologies to control the temperature, humidity, and purity of the air in an enclosed space. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer.

HVAC is an important part of medium to large industrial and office buildings such as skyscrapers and hospitals, where safe and healthy building conditions are regulated with respect to temperature and humidity, using fresh air from outdoors.
