How Much Space Does a SpacePak Air Conditioning System Require?

General Size

• Spacepak systems come in several types, based on how large buildings are and how much space the ducts need to cover. This can make it difficult to determine the exact space requirements of the Spacepak unit because different buildings have different needs. But in most cases, the Spacepak can be installed in confined spaces such as closets as long as you have enough room for the unit and you have vents that open the closet into larger air spaces. In wider areas, the unit can fit in conditioned or non-conditioned spaces.

Clearance

• The Spacepak needs a certain amount of clearance wherever it is installed. For the primary return air opening, 38 inches of minimum vertical clearance is needed from the top to the bottom of the unit. Three to four feet of clearance are needed between the fan coil unit and the wall where the return duct goes back into the house. These clearance spaces prevent a buildup of heat or debris.

Outlets

• The outlets are the vents that the Spacepak uses to channel air into the living space being cooled. Conventional grilles are typically in the floors and are at least 8 inches wide. The Spacepak outlets can be in ceilings, walls or floors and are only 5 inches in diameter. They are small squares designed to be unobtrusive.

Ducts

• Duct sizes can vary based on the size of the system. Inlets can range between 15 and 24 inches. Suction lines, however, are only around 7/8 of an inch. Supply tubes are a notable 2 inches in diameter, much smaller than traditional supply ducts. This makes it easier to install in areas where traditional duct work is not present or would not fit.
