A ductless air-conditioning system is an air-conditioning unit mounted on the inside of a wall to deliver cool air into the room or on the outside of the house to add permanent air conditioning to homes that do not have ductwork installed.
Ductless air-conditioning systems, also referred to as mini-splits, are alternatives to window-mounted or central air-conditioning systems. They work in a way that compresses low-pressure refrigerant to transform it into high-pressure gas by use of force. The condenser and fan in the system work jointly to drive away accumulated heat, thus causing the refrigerant to come out as a high-pressure liquid.
Similar to a conventional split system, ductless air conditioners are composed of outdoor condensing units that help in reducing interior noise. Mini split systems house all three components together in separate indoor units that are strategically placed throughout the building, unlike the central air conditioners that employ a single air handler, blower and evaporator coil. Ductless air conditioners are extremely inconspicuous and have numerous applications including residential, commercial and institutional buildings. Ductless air-conditioning systems are worth considering because they are energy-efficient, cost-saving over the life of the equipment and provide a quite low noise with enhanced comfortable cooling effects.
