摘要(Abstract):
研究了氯化钙为吸附剂,甲醇为吸附质的吸附式热泵吸附床的特性,并建立了相应的数学模型。最后得到吸附和解吸过程中吸附床内各点温度随时间的变化关系,并通过实验验证了模型的正确性。
Adsorption bed characteristic of absorption heat pump using CaCl_2-CH_3OH working pairs was studied.At the same time,the corresponding mathematical model was established.Temperatures of each point in the adsorption bed that change over time were acquired,in the course of adsorption-un adsorption.Moreover,the reliability of the model was validated by experiment.
