Heating, ventilating, and air conditioning (HVAC) is the science of vehicular and indoor environmental comfort. This science strives to offer suitable indoor air quality and thermal comfort to the occupants of the building in which he resides. HVAC systems are comprised of a combination of mechanical equipment and energy sources such as electricity, gas, oil, and coal. These energy sources transform the stored mechanical energy into usable electrical energy for heating, ventilating, and cooling purposes. The ventilation system removes particles from the air and directs them outside through a ventilation system. The air is then returned to the living space via an air duct system.
The Lazy Way To Heating, Ventilation, And Air Conditioning
One of the most commonly installed HVAC units are the air conditioners. Air conditioners cool a room by dehumidifying the air and transferring the moisture to the air circulating fan. Some HVAC units use water for this purpose, while others employ Freon. Air conditioners are available in different types such as window types and central air conditioners. Window types use Freon to lower the humidity, while central air conditioning units utilize chilled water for the same purpose. Heating and ventilation units are used for warming, ventilating, and conditioning rooms and spaces.
An HVAC unit requires regular maintenance for it to operate efficiently, so hiring a qualified HVAC technician may be a good idea for owners.
