A comparative evaluation of different heat-recovery schemes as applied to a two-bed adsorption chiller

This study investigates the efficiency of two distinct heat-recoveryschemes as applied to the two-bed silica gel–water adsorptionchiller. Performance predictions stemming from an experimentally verified distributed-parameter model compare favorably with the experimental results at various operating conditions. Our study highlights the pivotal role played by heat-recoveryschemes to ameliorate the chiller performance and substantially improve the coefficient of performance (or COP). The twodifferentschemes essentially offer the same cooling capacity and similar COP boosting capability. In the studied working conditions of atwo-bedadsorptionchiller, the difference in COP by using the twoschemes is less than 5%.
