A duct-free system, also known as a “split” air conditioner system, is made up of or includes two units: an indoor unit to deliver conditioned air to the room, and an outdoor unit to remove heat collected from the space. The compact refrigerant lines run between the two units. The system eliminates the need for ductwork. Duct-free systems are not just ideal for older homes that have no ductwork and room additions, but also in rooms that just never seem to be the right temperature and are never comfortable.
Whether you’re creating a quiet, comfort controlled room, or simply want to heat or cool an area without expensive ductwork, Daikin, Mitsubishi and Carrier’s duct-free systems set a new standard for efficiency, great looks and comfort.
Duct-free systems are much simpler and economical to install because they only have three basic parts: an outdoor condensing unit, an indoor unit, and the components that connect the two.
Duct-free systems are ideal for home or office additions to replace unsightly window units, and for renovations or retro-fits where it’s important to preserve the building’s original appearance.
The vapor then passes through a compressor where it is compressed into a high pressure, high temperature vapor. The hot vapor then circulates into the indoor coil. As indoor air passes over the indoor coil, it absorbs heat from the coil. The warmed air is then redistributed through the duct system.
