The demand for domestic air conditioning is growing in Wales. Based on current climate change scenarios Wales is expected to experience a rise in average annual daily temperature of between 2°C and 4°C by 2080 (UKCIP).
Therefore the demand for domestic air conditioning systems is likely to continue to rise over this century.
All air conditioning systems require an energy input to function. Most standard vapour compression chillers are motor or engine driven, deriving their energy inputs mainly from fossil fuel sources. In order to mitigate the potential contribution to climate change of increased numbers of air conditioning units in Wales it is necessary to seek alternative energy sources to provide the energy input required for cooling.
