Apackaged terminal air conditioner (PTAC) is a type of self-containedheating and air conditioning system intended to be mounted through a wall.[1] The first practical semi-portable air conditioning unit was invented by engineers atChrysler Motors. It entered the market in 1935, and was designed to fit under a window like many modern PTACs.[2]
PTACs are commonly found in commercial settings (hotels, motels, hospitals), or multifamily facilities (senior housing, condominiums, apartment buildings). PTACs are mostly used to cool individual living spaces, there are units which offerresistance heating and/orheat pumps.[3] (The latter are more properly described as packaged terminal heat pumps or PTHP). PTACs with support for external heating through ahydronic heating coil ornatural gas heating also exist. Typical PTAC heating and cooling capacity values range from 7,000–19,000BTU/h (2 to 5.5kilowatts) nominal.[4]
PTACs are commonly installed in window walls and masonry walls, with multiple standard dimensions available including 42×16 inches (1067x406 mm), 36x15 inches, and 40x15 inches. Their installation typically requires the following:
