Air Conditioning and Vapor-Compression Cooling

Vapour-compression refrigeration or vapor-compression refrigeration system (VCRS), in which the refrigerant undergoes phase changes, is one of the many refrigeration cycles and is the most widely used method for air conditioning of buildings and automobiles.

Air conditioning, often abbreviated as A/C (US) or air con (UK), is the process of removing heat from an enclosed space to achieve a more comfortable interior temperature and, in some cases, controlling the humidity of internal air.

Solar air conditioning, or "solar-powered air conditioning", refers to any air conditioning (cooling) system that uses solar power.

An evaporative cooler (also known as evaporative air conditioner, swamp cooler, swamp box, desert cooler and wet air cooler) is a device that cools air through the evaporation of water.

A dehumidifier is an air conditioning device which reduces and maintains the level of humidity in the air.

District cooling is the cooling equivalent of district heating.

Variable refrigerant flow (VRF), is an HVAC technology invented by Daikin Industries, Ltd. in 1982.

Heat recovery ventilation (HRV), also known as mechanical ventilation heat recovery (MVHR) is a ventilation system that recovers energy by operating between two air sources at different temperatures.

Ice storage air conditioning is a form of thermal energy storage in which cooling capacity is stored by freezing water and recovered later by melting the ice.
