摘要
基于一类不可逆热泵的一般循环模型,以每单位时间总成本的泵热率作为热经济学目标函数,研究投资成本、供热成本、其它费用成本和几种主要不可逆性对热泵性能的影响.导出热泵的热经济学目标函数和性能系数间的基本优化关系所满足的方程,由此可计算出最大热经济目标和对应的热泵的性能参数,确定了热泵的最佳工作区域和重要参数的性能界限.讨论了不同导热规律下,热泵的基本优化性能.
Based on the cycle model of a class of irreversible heat pumps, the heating load of the total cost per unit time is taken as a thermoeconomic objective function and used to (investigate) the influence of investment cost, supplying-heat cost, other charge cost, and several main irreversibility on the performance of the cycle. The fundamental optimal relation between the thermoeconomic objective function and coefficient of performance is derived. The maximum objective function and the corresponding parameters of performance are calculated. The optimal operated regions of heat pump and bounded of some importance performance parameters are determined. The optimal performances of heat pump at the different heat transfer laws are discussed.
