The design of HVAC systems is applied to thermodynamics, fluid mechanics and fluid machinery, and is an important sub-discipline in the field of mechanical engineering.
Sometimes R is also added to the abbreviation HVAC, which means refrigeration, the abbreviation becomes HVAC&R or HVACR, or R is added to the abbreviation, minus V, which represents ventilation, and the abbreviation becomes HACR.
