摘要
导出了吸附式太阳能冰箱制冷效率的表达式并进行了讨论。研制的冰箱样机,采光面积为1.1m^2,有效容积103L,用活性炭做吸附剂,甲醇做制冷剂。在最大太阳辐射强度为864W/m^2—622W/m^2条件下,共制冷效率约为11％,最高达15％。实验结果在一定程度上反映了环境温度、太阳辐射强度对制冷效率的影响。
A solar powered adsorption ice maker has been studied theoretically and experimentally. The derivation of net coefficient of performance (COP) for ice maker is obtained from the theoretical analysis. A solar adsorption ice maker with active carbon-methanol pair was designed for the experimental study. The area of solar collector for the ice maker is 1.1m2, and the volume of the refrigerator is 103 litres. Its net COP from the experiments is about 11% and the maximum COP is 15%.
