N2 - The adsorption refrigeration chiller is environmentally friendly because of the use of a natural refrigerant and the use of a low-grade thermal energy as the driving energy source. In this paper, an experimental investigation of a reheating two-stage adsorption chiller was conducted, and the working principle of the cycle was also introduced. The coeffi cient of performance and the cooling capacity were calculated to analyze the performance of the chiller. Our objective was to identify the eff ect of the temperature of the heat source and the eff ect of cycle time on the performance if the chilled water outlet temperature is fi xed at 9°C during the experiment. Experimental results showed that the performance of the chiller improved with increasing heat source temperature and that a total cycle time between 2000 to 2500 s yields bett er performance for the chiller.
