Heating, ventilation, and air conditioning (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. ""Refrigeration" is sometimes added to the field's abbreviation as HVAC&R or HVACR, or "ventilating" is dropped, as in HACR (as in the designation of HACR-rated circuit breakers).
