Solar Air Conditioning: A Review of Technological and Market Perspectives
INTRODUCTION Solar-assisted cooling appears to be a promising alternative to conventional electrically driven air-conditioning units from an environmental point of view since it results in decreased CO2 emissions and, in the case of prevailing solar-cooling technologies, the elimination of chlorofluorocarbons (CFCs) and hydro-chlorofluorocarbons (HCFCs). In addition, SAC can contribute significantly to dealing with continuously increasing peak electricity loads during summer, which burden both the generation and transfer capacities of electricity utility companies, as well as consumers. The heat-driven, solar-assisted chillers seem, in this sense, likely to have an excellent potential in the space
air-conditioning businesses, although so far they are not really a competitive alternative, in market terms, to conventional vapour compression cooling (VCC) systems.
