Since this world has come into existence, people have struggled to make their lives comfortable. HVAC stands for heating, ventilation or ventilating and air conditioning. HVAC technology is used indoor for vehicular, domestic, official or environmental comfort. It is mainly aimed at thermal comfort which is the state of mind in which people feel satisfaction with the thermal environment. Subjective evaluation mostly assesses it. In simple words, HVAC technology provides peace of mind or mental satisfaction.
Heating, ventilation, and air conditioning technology (HVAC technology) are used to make indoor quality acceptable for the people inside the building or their rooms. HVAC technology is linked to the mechanical engineering field. Fluid mechanics, heat transfer and thermodynamic are its fundamental principles. Sometimes, scientists add refrigeration to abbreviations as HVAR or HVAC&R, which stands for heating, ventilation, air conditioning and refrigeration.
HVAC technology is playing a significant role in all official and industrial buildings whether they are small, medium or large. It is very useful where healthy and safe conditions are to be regulated in accord with temperature and humidity such as skyscrapers, aquariums, onboard vessels, etc. You can also use both words as synonyms to each other either ‘ventilation’ or ‘ventilating’.
