摘    要:

为探讨新型吸附式制冷机的工作性能,对吸附式制冷机中吸附床的工作性能及蒸发器的换热性能进行研究。研究结果表明:吸附床循环水路的循环时间少于5 min;蒸发器内制冷剂蒸发是自然对流,属于池沸腾,并且制冷剂池沸腾传热系数较低,最大约为403.4 W/(m2·K)。

Abstract: In order to investigate the performance of the novel type of adsorption chiller, the performance of adsorber and heat transfer of the evaporator in the adsorption chiller were presented. The results show that the cycle time of recycled water is less than 5 min, and the heat transfer in the evaporating adsorbate process called pool boiling belongs to the natural convection. And the performance of the heat transfer is very poor, with the maximum of coefficient of heat transfer 403.4 W/(m2·K).
