Mini-Split Ductless Air Conditioning
Mini-split ductless air conditioning (AC) systems are a great solution to your space additions that need cooling and running duct-work is just not a feasible solution in some Chicago homes.
Mini split ductless air conditioning or also known as heat pumps (mini splits), make good retrofit add-ons to houses with “non-ducted” heating systems, such as hydronic (hot water heat), radiant panels, and space heaters (wood, kerosene, propane). They can also be a good choice for room additions, where extending or installing distribution ductwork is not feasible.
Like standard air-source heat pumps, mini splits have two main components: an outdoor compressor/condenser, and an indoor air-handling unit. A conduit, which houses the power cable, refrigerant tubing, suction tubing, and a condensate drain, links the outdoor and indoor units.
The main advantages of mini splits are their small size and flexibility for zoning or heating and cooling individual rooms. Many models can have as many as four indoor air handling units (for four zones or rooms) connected to one outdoor unit. The number depends on how much heating or cooling is required for the building or each zone (which in turn is affected by how well the building is insulated). Since each of the zones will have its own thermostat, you only need to condition that place when someone is there. This will save energy and money.
Ductless mini-split systems are also often easier to install than other types of space conditioning systems. For example, the hook-up between the outdoor and indoor units generally requires only a three-inch hole through a wall for the conduit. Also, most manufacturers of this type of system can provide a variety of lengths of connecting conduits. If necessary, you can locate the outdoor unit as far away as 50 feet from the indoor evaporator. This makes it possible to cool rooms on the front side of a building house with the compressor in a more advantageous or inconspicuous place on the outside of the building.
Since mini splits have no ducts, they avoid the energy losses associated with ductwork of central forced air systems. Duct losses can account for more than 30% of energy consumption for space conditioning, especially if the ducts are in an unconditioned space such as an attic.
In comparison to other add-on systems, mini splits offer more flexibility in interior design options. The indoor air handlers can be suspended from a ceiling, mounted flush into a drop ceiling, or hung on a wall. Floor-standing models are also available. Most indoor units have profiles of about seven inches deep and usually come with sleek, high tech-looking jackets. Many also offer a remote control to make it easier to turn the system on and off when it’s positioned high on a wall or suspended from a ceiling.
Mini-split ductless systems can also help to keep your home safer since there is only a small hole in the wall. Through-the-wall and window mounted room air-conditioners can provide an easy entrance for intruders.
Ductless mini-splits are the ideal air conditioning solution for installations where adding ductwork is impractical or too expensive. The matched combination of indoor unit and outdoor condenser is efficient and easy to install without the extra cost of construction to run ducts.
Mini split Air Conditioners or Heat Pumps have two main components: an outdoor unit containing compressor and condenser, and an indoor air-handling unit, containing evaporator and blower. A conduit, which houses the power cable, refrigerant tubing and condensate drain, links the outdoor and indoor units. Ductless mini split air conditioners have numerous potential applications and advantages. They are perfect for those home/business owners that do not have central air conditioning, and do not want to settle for the noise, insecurity and inefficiency of window AC units.
