本文首次探讨了将固气化学吸附式制冷循环与涡旋式膨胀机相结合的小型热电联产装置的可能性。这项工作的创新之处在于，它能够在不加剧能源短缺和环境影响的情况下，连续、同时地生产制冷和电力。为了确定实现1000 W功率输出的热电联产模式的适当运行条件，首先研究了每个组件的单独建模，并通过实验数据进行了验证。随后，通过对两个组件的集成建模，研究了热电联产的性能，以证明这一概念的可行性。然而，由于化学吸附和膨胀串联时的相互约束，在单个模型中确定的相同条件下，热电联产模式的输出功率仅为原始期望的三分之一左右。讨论了提高整体性能的方法，包括反应介质的选择，对今后的实际研究具有参考价值。
The present work for the first time explores the possibility of a small-scale cogeneration unit by combining solid–gas chemisorption refrigeration cycle and a scroll expander. The innovation in this work is the capability of producing refrigeration and electricity continuously and simultaneously without aggravating the energy scarcity and environmental impact. Individual modelling for each component, which has been validated by experimental data, was firstly investigated in order to identify the proper operation condition for the cogeneration mode achieving 1000 W power output. Subsequently, with the integrated modelling of two components the cogeneration performance was studied to demonstrate the viability of this concept. However, because of the mutual constraint between the chemisorption and the expansion when they link in series, the power output of the cogeneration mode was only around one third of the original expectation under the same condition identified in the individual modelling. Methods of improving the global performance including the selection of reactive mediums were also discussed and would be of referable value for the future practical investigation.
