How It Works.
Also known as “mini-duct” systems, high-velocity air-conditioning generally makes use of an outdoor compressor to cool the air, combined with a high-pressure blower typically mounted in the attic.
Instead of large metal ductwork, this technology, developed by SpacePak, makes use of flexible tubing only two inches in diameter. The insulated tubes can be threaded behind walls or inside closets without damaging sheetrock or plaster. This makes the system much quieter than air-conditioning with conventional metal ductwork.
A mini-duct system also dehumidifies the air more effectively. The high-pressure blower compresses the air and allows it to be in contact with the cooling coils longer, which reduces the temperature and gets rid of more humidity.
Its All Central.
Actually, “high-velocity” and mini-duct” systems are simply different names for the exact same kind of super-efficient and comfortable central air-conditioning systems. These systems are really quiet, disperse the cool air uniformly throughout your house, and dehumidify extremely efficiently.
The words “high velocity” and “pressure” might make you think these systems are noisy. Actually, you can hardly hear them running, and there is no air flow noise at the tiny outlets.
In two-story houses, the mini-ducts are run down from the attic through the corners of the closets or inside walls to the first floor. In a single-story home, the entire system is found in the attic with outlets in the ceiling below.
SpacePaks mini-duct systems make use of common, high-efficiency, outdoor air-conditioning compressor units. With this mini-duct system, cool air blows out from small two-inch openings in the ceiling or high up on the walls Site . You can hardly notice the outlets when they are painted the exact same color as the room. For a decorative look, natural wood outlets are available.
