基于火用分析的太阳能热泵系统优化研究
Optimization on solar-assisted heat pump system based on exergy analysis
摘要
Abstract
Based on the first and second law of thermodynamics, exergy models of the non-direct expansion solar heat pump system are established here. According to the system input exergy characteristics,this paper proposes the cost exergy efficiency for the first time,which is the ratio of output exergy and cost exergy (electric energy and conventional energy) ,and uses it as the optimization index of solar heat pump system. Taking a villa in Beijing as an example,this paper applies the cost exergy efficiency in design optimization analysis of solar heat pump system and obtains the optimum proportion of the solar collector area and the storage water tank volume. The calculation results show that the cost exergy efficiency increases by 15 percent after the optimization. The research results provide a theoretical basis for design and operation of the system application in Beijing region.关键词
