What is a ductless Mini-Split Air Conditioner? (Back
to Top)
Ductless air conditioners are called "mini-split" systems
because they are similar to a regular ducted split central air conditioner, only
on a smaller scale. A split system means that the compressor/condenser unit is
located outdoors and "split" from the indoor cooling coils/blower. Just a small
three-inch diameter hole is cut in the wall to run the tiny refrigerant lines
and electric wires to the indoor cooling units.
With the compressor outdoors and an indoor cooling unit
mounted high on a wall or ceiling, they are super-quiet (sounds like a
"whoosh"). These units are typically even quieter than many ducted central air
conditioners. In a central unit, huge amounts of air must wind through complex
ducts with many bends and shape changes, all of which contribute to noise.
Mini-split ductless air-conditioners are a preferred option
to trying to use several room air conditioners to cool an entire house. Window
units may block the window.
Although the efficiency ratings of ductless systems (SEER
from 10 to 12) are not as high as the top-of-the-line central air conditioner
(SEER up to 16), they can still be more efficient than window, wall and even
central units. 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 a unconditioned space such as an attic.
Heat pump models are also available for keeping warm. If
you hate that first shot of chilly air in the winter each time the furnace or
heat pump blower starts, select a ductless model with a soft, slow start and a
pre-heater for the air. For colder climates, some of the heat pump models also
have backup electric resistance heat.
Ductless, mini split-system air-conditioners and heat pumps
(mini splits) have numerous potential applications in residential, commercial,
and institutional buildings. The most common applications are in multifamily
housing or as 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 and small
apartments, where extending or installing distribution ductwork (for a central
air-conditioner or heating systems) is not feasible. Applications in other types
of buildings include: recording studios, school classrooms; perimeter cooling
for office buildings; additional cooling for restaurant kitchens; and cooling
for small offices within larger spaces, such as arenas, warehouses, and
auditoriums.
The primary disadvantage of mini splits is their cost. Such
systems cost about $1,500-$2,000 per ton (12,000 Btu per hour) of cooling
capacity. This is about 30% more than central systems (not including ductwork)
and may cost twice as much as window units of similar capacity.
The installer must also correctly size each indoor unit and
judge the best location for its installation. Oversized or incorrectly located
air-handlers often result in short-cycling, which wastes energy and does not
provide proper temperature or humidity control. Too large a system is also more
expensive to buy and operate.
