The Effect of Multi-irreversibilities on Thermoeconomic Performance of a Heat Transformer

Abstract

【中文文摘】基于一类不可逆三热源热变换器的循环模型,提出以每单位成本的泵热率作为热经济学目标函数,优化热变换器的各种性能参数.分析内不可逆性、热漏和经济参数对热变换器性能的影响,利用数值解计算热经济学目标函数的最大值及所对应的各种性能参数. 【英文文摘】The heating load per unit cost is taken as the thermoeconomic objective function with the cycle model of a class of irreversible three-heat-source heat transformers as the basis. The objective function is used to optimize the performance of the cycle. The effect of internal irreversibility, heat leak and economic parameter on the performance of the cycle is analyzed. The maximum thermoeconomic function and the corresponding performance parameters are obtained by using numerical calculation. The results obtained here provide some valuable guidance for the optimal design and operation of practical systems.国家自然科学基金资助项目(59976033
