All You Need To Know About HVAC

HVAC (Heating Ventilating and Air Conditioning) is the technology of indoor environmental quality and comfort, based on the subjects of fluid mechanics, thermodynamics, and heat transfer. HVAC is very important in the design of large and medium-sized buildings and skyscrapers. Their purpose is to keep inhabitants comfortable, healthy, and safe by regulating temperature and humidity, and channeling ‘fresh air’ from outdoors. The method of removing and delivering air into a particular space is termed ‘room air distribution’. Essentially there are three types for heating and cooling the space you require; Forced Air systems, Gravity systems, and Radiant systems. Forced air uses a blower (a fan operated by electricity) to push either furnace-generated heat or cool air from a central air conditioner through a series of ducts to the rooms you need climate-controlled. As the warm air fills the room, it pushes the cold air into another set of ducts that flow back into the furnace. The same process is used to cool your place down in the heat. This is an adjustable system; you can increase or decrease the amount of air flowing through your home.

Gravity systems also have a similar process where the heated air rises, forcing the cold air into ducts that return it to the furnace, and redistributing it back into your space. The heat registers this system uses are usually placed high on the wall, as they must be higher than the placement of the furnace to operate properly. It will not, however, keep your space cool, as it’s not designed to function that way. Radiant systems can be installed in walls, floors, or ceilings. The heat they generate warms the air of the room in question. Radiators are the most common form of this system. Radiant systems cannot distribute cool air. Radiators and convectors use heated water to warm their spaces. They may depend on gravity, or a circular pump to move the heated water from the boilers to the radiators. This is known as a hydronic system. Regardless of what type of structure you wish to climate-control, you should be able to find a system that’s just right for you. Make sure to do your homework on your contractor; remember that the quality of your installation is a huge factor, even more so than Heating and Cooling Prices.
