A Packaged Air Conditioner Terminal (often abbreviated PTAC ) is a complete type of heating and air conditioning system commonly found in hotels, motels, senior housing facilities, hospitals, condominiums, apartment building, space add-ons & amp; sunroom. Many are designed to pass through walls, have ventilation and heat sink inside and outside. Different standard dimensions found on the market include 42ÃÆ'-16Ã, inch (1067Ã, xÃ, 406Ã, mm), 36x15 inches, and 40x15 inches.
Although PTAC is mostly used to heat or cool a living space using only electricity (with resistive and/or heat pump heaters), there is a PTAC cooling-only with external heating via hydraulic heating coils or natural gas heating. Typical PTAC heating and cooling capacity ranges from 2 to 5.5 kilowatts (7,000-19,000 BTU/h) nominal. One feature of PTAC is that the condensate discharge pipe is not necessary because the condensate water extracted from the air by the evaporator coil is pulled by the condenser fan onto the surface of the condensate coil in which it evaporates. Conventional PTAC still needs condensate drainage to be installed. The first practical semi-portable air-conditioning unit was created by engineers at Chrysler Motors and offered for sale starting in 1935.
PTAC is generally installed on the walls of windows and masonry walls. Their installation usually requires the following:
- Louvers
- Metal coating
- Heating coil
- PTAC itself
- Room cover
