研制了一套吸附式制冷系统，并进行了试验，尝试了各种操作程序。实验结果表明，与单吸附床基本循环系统相比，两吸附床间热回收操作可使系统COP提高25%左右。实验还证明，质量回收对于热回收吸附制冷操作是非常有效的，这可能有助于获得超过10%的COP增加。对基本间歇式吸附循环、连续式双吸附床热回收循环、质量回收循环、质量回收与显热回收、质量回收与显热和吸附热回收等各种热质回收循环的COP进行了理论分析。理论计算结果与实验值吻合较好。基于所建立的理论模型，可以预测真实的吸附式制冷系统在不同运行工况下的COP。(C)2001年由Elsevier Science Ltd和IIR出版。All rights reserved.
An adsorption cooling system was developed and tested and various operation procedures have been tried. The experimental results show that the heat recovery operation between two adsorption beds will increase the COP by about 25% if compared with one adsorber basic cycle system. It was also proved that mass recovery is very effective for heat recovery adsorption cooling operation, which may help to obtain a COP increase of more than 10%. Theoretical analyses on the COP have been completed for various heat and mass recovery cycles, such as basic intermittent adsorption cycle, continuous two-adsorber heat recovery cycle, mass recovery cycle, mass recovery with sensible heat recovery, and mass recovery with both sensible heat and heat of adsorption recovery. The theoretical results are in good agreement with experimental values. Based upon the developed theoretical model, it is possible to predict the COP for various operation procedures of a real adsorption cooling system. (C) 2001 Published by Elsevier Science Ltd and IIR.
