HVAC stands for Heating Ventilation and Air Conditioning. It is a set of technologies mainly used to regulate room temperature, humidity and Air flow within a specified area. It is designed to provide thermal comfort and acceptable indoor air quality. The HVAC system design is the subject of mechanical engineering. It is based on the principle of thermodynamics, fluid mechanics, and heat transfer. HVAC systems can be used for both domestic and commercial buildings. It is comprised of central air conditioning, heating, and ventilation system.
HVAC technology is used to create a comfortable and luxurious environment indoor or in vehicles. It is very important in the design of medium to large industrial and office building. The main example of the use of this technology is: Shopping Malls, Business Offices, Hotels, Restaurants, Schools and Colleges, Vehicles etc.
Its main goal is to provide thermal comfort, proper ventilation to remove unpleasant smell and unnecessarily moisture within reasonable installation, operational and maintenance costs.
HVAC is bunch of technologies. It is based on the inventions of some famous scientists like Nikolay Lvov, Michael Faraday, Willis Carrier, Reuben Trane, James Joule, William Rankine, Sadi Carnot, and many others.
