HVAC is the technology of indoor and vehicular environmental comfort. 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. "Refrigeration" is sometimes added to the field's abbreviation, as HVAC&R or HVACR or "ventilation" is dropped, as in HACR (as in the designation of HACR-rated circuit breakers).
Smoke and heat exhaust ventilation systems, also known as "SHEVS" are natural or powered systems to remove smoke from a building allowing low level escape routes to be kept clear of smoke and reducing damage to the building. In order to design the most effective smoke and heat ventilation solution, it is important to consider a wide range of specific factors. We’ve outlined these below.
