An air conditioner (often referred to as AC ) isa home appliance, system, or mechanism designed to dehumidify and extract heat from an area. A single hosed unit has one hose that runs from the back of
the portable air conditioner to the vent kit where hot air can be released.
Another application for portable air conditioner units is for the temporary rental in emergency situations such as power failures at warehouses, offices, or data centers. Portable air conditioners are movable units that can be used to cool a specific region of a building or home in a modular fashion, not requiring permanent installation. For large buildings, ground source-coldness is successfully used to reduce energy consumption of central air conditioner systems, often in combination with heat pump based heating systems.
Air conditioners (for cooling) and heat pumps (for heating) both work similarly
in that heat is transferred or "pumped" from a cooler heat source to a warmer
"heat sink". PTAC systems may be adapted to provide heating in cold
weather, either directly by using an electric strip, gas or other heater, or by
reversing the refrigerant flow to heat the interior and draw heat from the
exterior air, converting the air conditioner into a heat pump. Since
evaporation occurs when heat is absorbed, and condensation occurs when heat is
released, air conditioners use a compressor to cause pressure changes between
two compartments, and actively condense and pump a refrigerant around. Visit to find out how to choose the right Casement Air Conditioner, Casement Window Air Conditioners, Small Air Conditioner, small room air

Throughout the second half of the 20th century, nearly all air conditioners used chlorofluorocarbons (CFCs) as their refrigerant, but because these chemicals are damaging to Earth's ozone layer, CFC production stopped in the United States in 1995. ENERGY STAR qualified room air conditioners are 10% more efficient than non-qualified models. Room air conditioners originally qualified for the ENERGY STAR label in October, 1996.
If every room air conditioner sold had earned the ENERGY STAR, it would prevent 900 million pounds of greenhouse gas emissions annually, equivalent to the emissions from 80,000 cars
