Résumé

Solar Heat for Industrial Processes (SHIP) is a growing-interest concept in the context of the reduction of both energy consumption and greenhouse gases emissions. As industry often needs cooling power at negative temperatures, solar-fueled NH3/H2O absorption systems can be used for this task. In the context of the FriendSHIP European project, a novel design of absorption chiller is investigated for cooling production at -20°C and -40°C from 100-250°C solar heat, based on a GAX (Generator-Absorber heat eXchange) cycle with Plate Heat Exchangers (PHE). This innovative architecture can improve the heat and mass transfers and thus the performance compared to the standard single-stage cycle. In addition, manufacturing costs decrease, as the needed components are standardized and available on the market. As a demonstration, a prototype is built and tested with a target of cold production at -20°C. The experimental data are analysed to give insight for further improvements of the machine.
