Central Air Conditioning Units

Providing comfort during either warm or cold weather, central air conditioning units have been commonly used in residential homes and businesses or offices. This type of climate control system uses either ducts or pipes in distributing cooled or dehumidified air (or chilled water to heat exchangers) to several rooms in a certain building. Each duct or pipe ends in a vent installed in the ceiling or wall, or underneath the floor, such that the position of the duct or pipe should be somewhere that makes cooling efficient. Most commonly, ducts are crafted out of aluminium, a very light and thin metal.

As it can deliver ‘conditioned air’ to several rooms at the same time, central air conditioning units are also termed lately as split systems. The term also refers to describe the split components of the system. The first component, which incorporates the condenser and compressor, is situated outdoors. On the other hand, the second component which houses the evaporator is mounted in an air handler inside the building. Another term for the central system is the package system. This entails that all of the air-con components are sited in a single unit outside the building, usually on the roof or ground. However, this kind of central air-con system is now rarely used because of some impracticality it poses.

Central air conditioning units operate like any other regular air conditioner but with the following additional benefits:

Special state-of-the-art filter – When the air handling unit is turned on, the return-air ducts of the system draw in room air from different parts of the building. The drawn in air passes through a sophisticated filter that removes airborne particles like lint, dust, and other microscopic pollutants. After the filtering process, the ‘cleansed’ air is delivered back to the air supply ductwork and is distributed and circulated to the rooms.

Whisper quiet noise feature – Since the unit component that houses the condenser, fan, and the compressor is situated outside the home or office, there is lower to zero noise level heard indoors.

Before central air conditioning units are installed, heat-gain calculation is first performed to assess the heat the home or building is subject to. The calculation will reveal what size of unit is needed. Factors such as the amount of attic and wall insulation, the orientation of your home to the sun, and types and placement of windows and doors are also considered. The size of the unit is also important. The principle behind this is that an undersized unit cannot cool rooms down completely during the hottest days; and an oversized compressor costs more to operate as it consumes more electricity to run a bigger unit and does not lower humidity effectively. This is due to the rapid cooling of the air and then quickly shutting off, just before the cycle circulates. The proper air volume passes the coils to extract the necessary moisture. Thus, the result is a room that feels clammy and damp.

To ensure energy efficiency, environmentally friendly and cost cutting central air conditioning, proper consultation with proper people is essential before installation.
