【摘要】：為了研究氯化鍶混合吸附劑-氨氣工質(zhì)對的非平衡吸附動力學(xué)模型,對混合比例為4:1(氯化鍶:膨脹硫化石墨)的氯化鍶-膨脹硫化石墨混合吸附劑的吸附與解吸性能進(jìn)行了測試與研究。發(fā)現(xiàn)其非平衡吸附過程是雙變量控制過程而不是單變量控制過程。通過對其等壓吸附/解吸過程及解吸滯后現(xiàn)象進(jìn)行進(jìn)一步分析,建立了氯化鍶混合吸附劑的動力學(xué)模型。分別用理論、實(shí)驗(yàn)及模型數(shù)據(jù)擬合吸附制冷過程的COP和制冷量,結(jié)果表明,所建立的非平衡動力學(xué)模型的擬合結(jié)果和實(shí)際結(jié)果吻合得很好。例如在蒸發(fā)溫度為0℃、環(huán)境溫度為25℃、熱源溫度為90.5℃以上時,擬合COP所帶來的最大誤差只有1.0%,而理論的平衡吸附性能計(jì)算所帶來的最大誤差為25.8%;理論得到的制冷量比實(shí)際值偏高188.1%,而擬合值只比實(shí)際值偏高2.1%。
[Abstract]:In order to study the non-equilibrium adsorption kinetic model of strontium chloride mixed adsorbent-ammonia working fluid pair, The adsorption and desorption properties of a mixture of strontium chloride and expanded graphite sulphide with a mixture ratio of 4:1 (strontium chloride: expanded graphite sulfide) were tested and studied. It is found that the non-equilibrium adsorption process is a bivariate control process rather than a univariate control process. Based on the analysis of isobaric adsorption / desorption process and desorption hysteresis, a kinetic model of strontium chloride mixed adsorbent was established. The cop and the refrigerating capacity of adsorption refrigeration process were fitted by theoretical, experimental and model data, respectively. The results show that the fitting results of the established non-equilibrium dynamic model are in good agreement with the actual results. For example, when the evaporation temperature is 0 鈩，
