摘要
提出一种复合式循环,将一对吸附床设置在溶液吸收-发生的回路中间。运用能量守恒和质量守恒原理对循环中各部件建立热力学模型,使用Matlab编程对其与常规单效吸收循环进行模拟计算与比较。结果表明,复合式循环的能效比在大部分工况下皆有6%～8%的提升,在小部分受限工况下与常规循环的表现差别很小。该循环除了可以减少热源和冷却水的消耗外,也为吸收式、吸附式制冷循环性能的优化研究提供新的方向。
A compound cycle which sets a pair of absorption beds in the absorption- generation circuit is presented. The thermodynamic model of every component is estab- lished based on energy and mass conservation. The performance of the compound cycle and single-effect cycle is simulated and compared by Matlab programming. The results show that the COP of the new compound cycle is from 6 percent to 8 percent greater than that of the single-effect cycle except some limited conditions. In addition to reducing the consumption of heat source and cooling water, the compound cycle also provides a new direction of optimization of absorption and adsorption refrigeration cycle.
