This position paper is a deliverable of the Task 38 â€œSolar Air-Conditioning and Refrigerationâ€ of the IEA Solar Heating & Cooling Programme. It describes the application of active solar heating and cooling technologies within the heating, ventilation and air-conditioning (HVAC) system of buildings in the context of increasing energy efficiency requirements.
After a brief technical description, followed by an overview of the cooling technologies available on the market, the paper focuses on the dominating technology: heat driven air-conditioning and refrigeration systems using solar thermal energy as the main driving energy. It subsequently argues for the wider application of Solar Air-Conditioning and Refrigeration (SAC) technologies due to their technical maturity, energy performances, economic viability and environmental benefits.
The document also addresses the technical potential and market opportunities of these technologies, as well as the existing measures supporting their market deployment.
