搭建了混合吸附剂吸附性能实验装置和混合吸附剂吸附式制冷系统实验台。通过实验研究,发现当质量比例为10∶3时,4A分子筛和铝条的混合吸附剂获得最佳吸附性能。同时对该混合吸附剂吸附制冷在不同解吸温度下的制冷性能进行了实验研究。结果表明:解吸温度从74.0℃逐渐升高到98.0℃时,蒸发温度随解吸温度的升高而降低,当解吸温度为98.0℃,蒸发温度最低为10.7℃;解吸温度从74.0℃逐渐升高到98.0℃时,系统制冷量与解吸温度成正比关系,解吸温度为98.0℃时,系统制冷效果最好,系统制冷量最大达到305 W。
Set up a mixed adsorbent adsorption performance experimental device and a mixed adsorbent adsorption refrigeration system bench. Through experimental research, we found that when the mass ratio of 10: 3, 4A zeolite and aluminum mixed adsorbent to obtain the best adsorption properties. At the same time, the adsorption performance of the mixed adsorbent at different desorption temperature was experimentally studied. The results showed that when the desorption temperature increased from 74.0 ℃ to 98.0 ℃, the evaporation temperature decreased with the increase of desorption temperature. When the desorption temperature was 98.0 ℃, the lowest evaporation temperature was 10.7 ℃. The desorption temperature increased from 74.0 ℃ to At 98.0 ℃, the cooling capacity of the system is directly proportional to the desorption temperature. When the desorption temperature is 98.0 ℃, the cooling efficiency of the system is the best and the cooling capacity of the system is up to 305 W.
