A novel solar-powered adsorption chiller with heat and mass recovery cycle was designed and constructed. The operation parameter effects on system performance were tests successfully. Test results indicated that the coefficient of performance and cooling capacity of the solar-powered adsorption chiller could be improved greatly by optimizing some key operation parameters, such as solar hot water temperature, heating/cooling time, mass recovery time, and chilled water temperature. With optimum operation parameters, this solar-powered adsorption chiller can produce a cooling capacity about 66 to 90W per m² collector area under the climatic conditions of daily solar radiation being about 16 to 21 MJ/m². Its daily solar cooling COP is about 0.1 to 0.13.
