摘要:
该文分析了双级溴化锂制冷循环传统的热力计算方法与不足,提出了一个全新的通过计算双级溴化锂制冷循环中间压力来确定热力循环的方法。并提出了中间压力计算的数学模型,即pm = p0·pk + Δp。通过计算机模拟计算,分别分析了热源温度、冷却水温度和冷媒水温度对Δp 的影响。以获得最大制冷循环热力系数为目标函数,通过优化方法确定影响Δp 各因素的加权系数,并获得了双级溴化锂制冷循环中间压力优化计算数学模型。简化和优化双级溴化锂制冷循环热力计算,使其获得最高热力系数。
Abstract:
T hrough the analysis of t radit ional thermodynamic calculat ion method and it s inadequacy, a new method through calculat ing intermediate pressure of two-stag e LiBr ref rigerat ion cycle to determine thermody namic cycle is advanced. And a calculat ion model of intermed-i ate pressure, p m = p 0 ·p k + $p , is introduced. T he influence of heat source temperature, cooling water temperature and cool media water temperature on Δp is separately analy zed throug h computer simulated calculation. T he w eighted coef ficients that have effect of the factors on Δp are determined throug h an opt imum method, and an opt imum model for calculat ing intermediate pressure in tw o-state LiBr refrigerating cycle is proposed. The calculat ion method of opt imum intermediate pressure is proposed. As a result, the thermodynamic calculation of tw ostag e LiBr refrig erat ing cycle may be simplified and opt imized. Then, this cycle could derive the highest heat ratio.
