What is a Ductless Mini Split System? Mini-splits have two main components: an outdoor compressor/condenser and an indoor air handling unit. Like central systems, a conduit, which houses the power cable, refrigerant tubing, and a condensate drain, links the indoor and outdoor units.
What Are the Best Applications? Mini splits can be effectively used in both residential and commercial buildings. They are currently most commonly used in multi-family housing or retrofit as add-ons to homes with "non-ducted" heating systems. They can also be a good choice for room additions and small apartments, where installing ductwork (for a central air-conditioner or heating systems) is not feasible or practical. Other opportunities for effective use include school classrooms, perimeter cooling for office buildings, additional cooling for office buildings, additional cooling for restaurant kitchens and cooling for small offices. They can also effectively cool smaller areas within larger spaces, such as arenas, warehouses or auditoriums.
What Are the Main Advantages? Mini-splits are small in size and very flexible for zoning because no ductwork is needed for heating and cooling individual rooms or areas. Each unit has its own thermostat, so you can adjust it to the requirements of the room or area.
Are They Energy Efficient? Since mini-splits have no ducts, they avoid the energy losses associated with the ductwork of central forced air systems. Duct losses can account for more than 30% of energy consumption, especially if the ducts are in a non-air conditioned space, such as an attic.
Can they Heat and Cool? Yes. Ductless mini split-systems are available in both air conditioner and air conditioner / heat pump models.
There's a mini split system to fit just about any installation, from single rooms to expansive spaces.
Our single, dual, tri and quad zone models offer an impressive array of capacities in both A/C and heat pump models. If you are familiar with a central system, you have the basic idea of what a split system is, an outdoor condensing unit and an indoor evaporator unit. The basic difference between the two is that with the central system the evaporator unit is typically found in the basement or attic and has ductwork branched off to the different rooms in your house.
With Mini Split Systems the evaporator is actually in the room being air-conditioned. The indoor unit has a quiet fan that blows across a cold aluminum coil while in the air conditioning mode. The indoor unit is usually a wall mounted type and this unit is connected directly to the outdoor unit by copper tubing and control and power wiring.
In the outdoor unit, a compressor cycles refrigerant to and from the indoor and outdoor unit and the room air is cooled or heated based on the direction the refrigerant flows between the two.
