本文首先把吸收式制冷循环抽象为一个卡诺热机驱动卡诺制冷机的三热源制冷循环,然后根据卡诺热机的最佳效率与供热率间的关系,以及卡诺制冷机的最佳制冷系数与制冷率间的关系,导出吸收式制冷循环工作于不可逆传热的情况下,最佳热力系数与制冷率间的关系。由此,给出最大制冷率和最大制冷率时的热力系数,并对其它最优性能作了简要讨论。
This paper first abstracts the absorption refrigeration cycle as a three-heat source refrigeration cycle driven by a Carnot engine, and then based on the relationship between the optimal efficiency of the Carnot engine and the heating rate and the optimal cooling of the Carnot chiller Coefficient and the cooling rate, the relationship between the optimal heating coefficient and the cooling rate is deduced when the absorption refrigeration cycle operates in the condition of irreversible heat transfer. As a result, the thermal coefficients at maximum and maximum cooling rates are given, and other optimal properties are briefly discussed.
