A basic ducted unit is installed with duct and outlets to all spaces requiring heating or cooling. The temperature will be regulated by the single temperature guage in one spot in the building, usually the Kitchen or Hall.
However, any house, office or other space consisting of various rooms can, for the sake of Air Conditioning Efficiency, be divided into sections or zones each controlled by a damper/s to regulate air flow to better manage the temperature level. The air conditioned space can then be selectively regulated via the dampers so that only the spaces in use have airflow.
By confining air flow to the spaces being occupied the A/C unit is allowed to work more efficiently and, because the whole volume of air is going into a smaller area, desired temperatures are reached quicker and maintained more easily. |
