   Packaged terminal air conditioner installed in a residential apartment. A packaged terminal air conditioner (PTAC) is a type of self-contained heating and air conditioning system intended to be mounted through a wall. [1] The first practical semi-portable air conditioning unit invented by engineers at Chrysler Motors. It entered the market in ...

3. Seasonal energy efficiency ratio - Wikipedia

   en.wikipedia.org/wiki/Seasonal_energy_efficiency...

   Air-conditioner sizes are often given as "tons" of cooling, where 1 ton of cooling equals 12,000 BTU/h (3.5 kW). 1 ton of cooling equals the amount of power that needs to be applied continuously over a 24-hour period to melt 1 ton of ice. The annual cost of electric energy consumed by an air conditioner may be calculated as follows:

4. Air conditioning - Wikipedia

   en.wikipedia.org/wiki/Air_conditioning

   Evaporator, indoor unit, or terminal, side of a ductless split-type air conditioner. Ductless systems (often mini-split, though there are now ducted mini-split) typically supply conditioned and heated air to a single or a few rooms of a building, without ducts and in a decentralized manner.

   Central, "all-air" air-conditioning systems (or package systems) with a combined outdoor condenser/evaporator unit are often installed in North American residences, offices, and public buildings, but are difficult to retrofit (install in a building that was not designed to receive it) because of the bulky air ducts required. [32] (Minisplit ...

6. Coefficient of performance - Wikipedia

   en.wikipedia.org/wiki/Coefficient_of_performance

   The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. [ 1 ] [ 2 ] Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs.
