Economic growth in developing countries and increased temperatures brought about by climate change is increasing the demand for air-conditioning worldwide. There is a huge growth potential for HFC-free cooling.
Global energy demand from air conditioners is expected to triple by 2050, although efficiency improvements could cut this demand in half. There are many examples of air-conditioning systems using natural refrigerants such as ammonia , carbon dioxide and hydrocarbons which have reduced global warming impacts. In some cases, facilities are opting for alternative technologies that do not use compression-cycle air-conditioning, such as desiccant and district cooling.

There are various types of units used for domestic air-conditioning including portable units, packaged units, window-type units and ducted and ductless split units.
Commercial / Industrial
Commercial air-conditioning usually relies on the use of large chillers to distribute cooled water around a building. Cool technologies used in commercial air-conditioning usually involve ammonia for larger chillers and hydrocarbons and carbon dioxide for smaller chillers.
Transport air-conditioning refers to air-conditioning found within the cabin of cars, lorries, buses and trains. The transport sector is particularly problematic in terms of emissions due to high leakage rates.
