Heating Ventallation Air Conditioning
The term heating AIr conditioning repair www.myairtoday.com/ ventilation means the process of drawing warm or cooling air through a system of ducts and vents to provide comfort. These systems are often built with one large duct and individual ones for each part of the house, with separate ducts for bathrooms and kitchens. The main purpose of this kind of air conditioning is to pull in warm air from outside and pull out cold air from indoors, thereby providing home comfort. The units used for heating air in domestic areas generally have a fan that blows the warmed air into the room, while the unit that circulates the cool air across the room has a closed end and is similar to the exhaust fan. A difference between ventilation and an exhaust fan lies in the way the heated air and the cool air are pulled in and released.
Since a heating system circulates air through ductwork, it is called by the names furnace, blower, and vent. The air that goes through these ducts and vents is called the “outside air” or “outside air conditioning” or “conditioning air”. This air is not heated or cooled, but merely moved, by a means other than natural convection. The reason behind heating vents that pull air in is to draw in and push out the hot air that results from heating a room. Since the air is drawn in and pushed out by the heating unit itself, the air inside the room remains constant temperature.
In contrast, air that is pulled in and released through the ductwork is heated by the heating unit, and the air stays constant temperature unless ductwork is cleaned. The vents and ductwork are cleaning to remove dust, debris, pollen, and mold. Since the “room” is heated and cooled, the air inside is kept at a constant temperature unless the room is cooled off. The most common application for heating and conditioning air conditioning units is in the mechanical shop, automotive shop, heavy industry, and manufacturing plant offices. For home use, most of these air conditioning and heating units are installed in the garage, kitchen, or utility room instead of the living areas.
