摘　　要： 本文选用活性炭作吸附剂、甲醇作吸附介质,从实验和理论两方面研究了吸附式制冷间歇循环效率COP的变化规律。从实验研究的结果中可知,最高解吸温度、吸附温度、冷凝压力和蒸发温度等对COP有不同程度的影响。当最高解吸温度在100℃附近时,COP最大。从理论分析中。导出了COP的表达式,并且COP表达式的计算值与实验结果吻合得较好。 The coefficient of performance (COP) of adsorption refrigeration cycle using activated carbon-methanol pair has been studied experimentally and theoretically in this paper. From the experimental research it is foumd that the values of COP depend on the condensing pressure of methanol vapor, the maximum desorpting temperature, the evaporating temperature and the adsorpting temperature. The COP reaches a maximum when the maximum desorpting temperature is about 100 degrees centigrade. Furthermore, a mathematical expression for COP is presented from the theoretical analysis, the experimental results and the values predicted by the COP expression have a good agreement.
