热泵定义的拓展及其效率表达式的改进 【英文篇名】 Discussion on development of heat pump definition and improvement of an exergy efficiency formula 【作者中文名】 张永贵; 【作者英文名】 By Zhang Yonggui ★Yanshan University; China; 【作者单位】 燕山大学; 【文献出处】 暖通空调, Hv ?效率; 改进; 【英文关键词】 heat pump; exergy efficiency; improvement; 【摘要】 认为热力学理论中定义的热泵与工程领域定义的热泵有所不同 ,按热力学理论中的定义 ,存在热泵效率大于 1的错误。提出了符合分析基本理论原则的效率表达式 ,并将修正的效率及供系数、损系数、损率同时纳入热泵分析过程 【英文摘要】 The concept of heat pump in thermodynamics differs from that in engineering. From the definition by the thermodynamics, it can be deducted that the exergy efficiency may be larger than one. Puts forward a new heat pump exergy efficiency formula according to the basis of exergy efficiency and introduces the exergy efficiency, supply exergy coefficient, exergy loss coefficient, exergy loss ratio into the exergy analysis of heat pumps.
