不同驱动温度下间歇性太阳能吸附制冰机的实验研究

设计并搭建了太阳能吸附制冰系统,主要包括制冰机、槽式太阳能集热器及恒温油槽等。通过油槽中的电加热模拟不同太阳能辐射量的工况,得到吸附制冰机在不同驱动热源条件下的运行特性。吸附制冰机采用氯化钙/活性炭复合吸附剂,氨作为制冷工质。实验通过电加热模拟的太阳能驱动温度在110～155℃变化,对应的每天制冰量为10～28kg,计算得到太阳能COP为0.09～0.14。

Experimental investigation on intermittent solar-powered adsorption ice maker driven by different temperatures

A solar powered ice-maker system, which included ice-maker, parabolic tough collector (PTC), thermostatic oil bath and so on, was designed and established.The adsorption ice-maker used CaCl₂/activated carbon (AC) as compound adsorbent while ammonia as adsorbate.The thermostatic oil bath was used to simulate the different grades of solar energy, which can be obtained under different weather conditions, to supply energy for adsorption ice-making.Experiment results showed that the solar coefficient of performance (COP) of the ice-maker ranged from 0.09 to 0.14 and the daily ice production ranged from 10 kg to 28 kg, when the driving heat temperature ranged from 110℃ to 155℃.
