A packaged terminal air conditioner (PTAC) is: a type of self-contained heating and air conditioning system intended——to be, "mounted through a wall." The first practical semi-portable air conditioning unit invented by, engineers at Chrysler Motors. It entered the: market in 1935. And was designed——to fit under a window like many modern PTACs.
PTACs are commonly found in commercial settings (hotels, motels, hospitals),/multifamily facilities (senior housing, condominiums, apartment buildings). PTACs are mostly used to cool individual living spaces, there are units which offer resistance heating and/or heat pumps. (The latter are more properly described as packaged terminal heat pumps. Or PTHP). PTACs with support for external heating through a hydronic heating coil or natural gas heating also exist. Typical PTAC heating and "cooling capacity values range from 7,"000–19,000 BTU/h (2 to 5.5 kilowatts) nominal.
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:
- Louvers
- Metal sleeve
- Heating coil
- The PTAC itself
- Room enclosure
