 Performance evaluation of multi-stage, multi-bed adsorption chiller employing re-heat schemeM.Z.I. Khan, K.C.A. Alam, B.B. Saha, A. Akisawa and T. Kashiwagi Renewable Energy, 2008, vol. 33, issue 1, 88-98 Abstract: This paper deals with the performance investigation of a silica gel/water-based multi-stage, multi-bed, six-bed adsorption chiller employing re-heat scheme. The innovative chiller is powered by waste heat or renewable energy sources of temperature between 50 and 70°C along with a coolant of inlet temperature at 30°C for air-conditioning purpose. The performance of the six-bed adsorption chiller using re-heat scheme is compared with that of the six-bed chiller without re-heat. With the same operating conditions, such as the heat transfer fluid inlet (HTF) temperatures, HTF flow rates, adsorption/desorption cycle time and same chiller physical dimension, it is found that both the cooling capacity (CC) and the coefficient of performance (COP) of the three-stage chiller with re-heat scheme are superior than those of the three-stage chiller without re-heat scheme.
