Packaged terminal air conditioner
Encyclopedia
A packaged terminal air conditioner (often abbreviated PTAC) is a type of self-contained heating and air conditioning
system commonly found in hotels and apartment buildings. Many are designed to go through a wall, having vents and heat sink
s both inside and outside. Different standard dimensions are found in the market including 42×16 inches (1067 x 406 mm), 36x15 inches, and 40x15 inches.
Although PTACs are used mostly to heat or cool a single living space using only electricity (with resistive and/or heat pump heating), you can find cooling only PTACs with external heating through a hydronic heating coil or natural gas
heating.. Typical PTAC heating and cooling capacity values range from 2 kilowatts (7000 BTU/Hr) to 5.5 kilowatts (19000 BTU/Hr) nominal. One characteristic of PTACs is that condensate drain piping is not required because the condensate water extracted from the air by the evaporator coil is drawn by the condenser fan onto the condenser coil surface where it evaporates. Conventional PTACs still require condensate drain piping to be installed.
PTACs are commonly installed in window walls and masonry walls. Their installation typically requires the following:
1) Louvers
2) Metal sleeve
3) Heating Coil
4) The PTAC
5) Room Enclosure

Heat sink
A heat sink is a term for a component or assembly that transfers heat generated within a solid material to a fluid medium, such as air or a liquid. Examples of heat sinks are the heat exchangers used in refrigeration and air conditioning systems and the radiator in a car...

Natural gas
Natural gas is a naturally occurring gas mixture consisting primarily of methane, typically with 0–20% higher hydrocarbons . It is found associated with other hydrocarbon fuel, in coal beds, as methane clathrates, and is an important fuel source and a major feedstock for fertilizers.Most natural...
