How is Ductless different than central air-conditioning?
The amount of cold air entering the room can he controlled by a thermostat or it can be regulated by an infra-red remote control, like a TV remote. One room or one area of a building can maintain a different temperature from another room or area in the same building. In a central air-conditioning system, refrigerant is pumped from the outdoor condenser coil indoors to a single indoor coil from which cooled air is distributed to each room through a system of ducts. In many houses and businesses, the amount of cold air in one room cannot be regulated without changing the temperature of every room in the building. What is “zone control”? Ductless Split Air-Conditioning Systems offer room-by-room or “zone” control, which minimizes over-cooling typical of central air-conditioning systems. As in the example at the beginning of this brochure, many school systems now use ductless systems to conserve energy during the summer when only staff members may be present.
