摘要/Abstract

摘要： 在低于100 °C热源、高于30 °C冷凝温度的条件下，为了获得-15 °C的冷冻工况，采用二级解吸过程设计了氯化钙/氯化钡吸附氨的吸附制冷系统，并对氯化钙/氯化钡工质对的吸附性能参数进行测试，由其性能数据拟合而得到吸附与解吸曲线、耦合吸附与解吸方程和传热方程，并建立系统模型进行仿真.结果表明，该系统可以利用85 °C的低温热源，在30 °C的冷凝温度条件下获得-15 °C的制冷温度，并达到2.62 kW的制冷功率.

Abstract: In order to achieve freezing condition under -15 °C while the heating source temperature is lower than 100 °C and the condensing temperature is higher than 30 °C, a C_aCl₂-B_aCl₂-NH₃ adsorption refrigeration system was designed with two-stage desorption cycle. A series of experiments were performed on two-stage adsorption test unit in order to get the adsorption and desorption data of the composite absorbents, which are the mixture of salt chloride and expanded graphite. By fitting the data into adsorption and desorption curve, we set a mathematic model of the system by combining the adsorption and desorption equations and heat transfer equations of the system. The performance of the system was simulated and the results show that the system is able to use 85 °C heating source for the output of -15 °C freezing temperature, when the condensing temperature is 30 °C. The cooling capacity of the system simulated is 2.62 kW.
