Its goal is to provide thermalcomfort and acceptable indoor air quality. HVAC system design is a subdisciplineof mechanical engineering, based on the principles of thermodynamics, fluidmechanics, and heat transfer. Refrigeration is sometimes added to the field'sabbreviation as HVAC&R or HVACR, or ventilating is dropped as in HACR (suchas the designation of HACR-rated circuit breakers).   HVAC is important in the design ofresidential structures such as single family homes, apartment buildings, hotelsand senior living facilities, medium to large industrial and office buildingssuch as skyscrapers and hospitals, onboard vessels, and in marine environmentssuch as aquariums, where safe and healthy building conditions are regulatedwith respect to temperature and humidity, using fresh air from outdoors.   Ventilating or ventilation (the V in HVAC)is the process of "exchanging" or replacing air in any space toprovide high indoor air quality which involves temperature control, oxygenreplenishment
