The main components of the Heating Ventilation and Air Conditioning systems are furnace, heat exchanger, evaporator coil, condensing unit, refrigerant lines, thermostat, ducts, and vents. HVAC technology is used to create a comfortable and luxurious environment indoor or in vehicles. Its main aim is to provide proper ventilation, thermal comfort, and to remove unpleasant smell and unnecessary moisture within reasonable installation, operational, and maintenance costs.
It is also very important in the design of medium to large industrial and office building. Some of the main examples of the use of this technology are: Business Offices, Restaurants, Shopping Malls, Colleges, Hotels, Vehicles, and Schools etc.
