在循环优化计算的基础上,对基本型直燃式串联三效溴化锂吸收式制冷循环和带蒸汽压缩装置的三效制冷循环进行了对比分析。分析结果显示,在选择合适的蒸汽压缩比提前下,带蒸汽压缩装置的三效制冷循环可以获得比基本的直燃型串联三效溴化锂吸收式制冷循环更高的循环COP值,并可将最高溶液温度降低至低于200℃,是一种颇具市场前景的制冷循环。
Comparison of Two Different Lithium Bromide Triple-effect Absorpt ion Refrigeration Cycles with Series Solution Circuit
Based on the optimal simulation, a comparison of the normallithium bromide triple-effect absorption cycle with series solution circuit and the same cycle with an additional vapor compression device has been carried out. Analysis shows that the latter can achieve a higher COP than the former, furthermore, it can notably reduce the highest temperature of solution in the cycle to a value lower than 200℃. Such kind of triple-effect absorption cycle will have a broad marketing prospect.
