利用自制的沸石分子筛,在自行设计的吸附式制冷模拟装置上,对吸附剂5A、NaY、CaY、13X及CaX等沸石分子筛和制冷剂水系统进行了制冷效果的测定;讨论了吸附速度、脱附温度对制冷效果的影响;通过吸附等温线的测定,计算了制冷循环系统中水的循环量,并测得分子筛再生时开始脱附的温度Ts值和再生后开始吸附的温度Ts’值。实验结果表明每公斤所研究的分子筛在单级吸附—解吸循环系统中能够产生制冷量为62—100千卡(Tev=0℃,Tcond=Tads=14.5℃,Treg=120℃)。
The self-designed adsorption refrigeration simulator was used to measure the refrigeration effect of zeolite 5A, NaY, CaY, 13X and CaX molecular sieve and refrigerant water system. The adsorption rate, The influence of temperature on the refrigeration effect was also studied. The water circulation in the refrigeration cycle was calculated by the determination of adsorption isotherms. The temperature Ts at which molecular sieves began to desorb and the temperature Ts’ at the start of regeneration were measured. The experimental results show that the molecular sieve studied per kilogram can produce a cooling capacity of 62-100 kcal (Tev = 0 ° C, Tcond = Tads = 14.5 ° C, Treg = 120 ° C) in a single stage adsorption-desorption cycle.
