江水源热泵区域供能系统成本分析

摘要

目前对区域供能的研究基本上是着眼于建筑能量消耗的多少而忽略了所消耗能源的品质，实际建筑的耗能与能量的品质关系密切，基于热力学第二定律的㶲分析方法能更好地反映区域系统的耗能状况。在对㶲分析和经济学研究的基础上，利用㶲成本分析方法，建立江水源热泵区域功能系统㶲成本分析模型。以实际的区域供能项目为背景，对江水源热泵热泵区域供能系统和常规水冷机组加锅炉系统进行㶲成本对比分析，对江水源热泵区域供能系统的应用起到了指导意义。%Current research on the regional energy supply is basically focused on the building energy consumption while ignoring the quality of the energy consumption. Energy consumption is closely related to the quality of the energy, exergy analysis method, which is based on a better second law of thermodynamics, reflects the regional system of energy consumption better. In this paper, based on the analysis of the exergy and principles of economics, Exergy cost analysis of river water source heat pump system model is established. Based on the actual regional energy supply project, the cost comparison of Exergy cost analysis between river water source heat pump district cooling and heating system and conventional water cooling unit as well as boiler system is carried out. The analysis method has guiding significance for practical application of river water source district cooling and heating system.
