排风热回收技术经济比较方法及不确定性分析
摘要:
为确定集中空调系统排风热回收技术的经济性,介绍了一种排风热回收技术经济比较分析方法:选取典型气象年数据,采用动态逐时模拟方法,利用Excel软件对数据进行处理。以重庆市某图书馆项目的排风热回收装置为例,比较了不同典型气象年数据对技术经济比较的不确定性影响,得出了排风热回收装置经济适用的结论,指出了分析时应选用的典型气象年数据来源。研究结果可为空调系统设计提供参考。
Abstract:
To determine the economic feasibility of exhaust air heat recovery technology in centralized air conditioning systems, this study presents a method for economic comparison analysis of exhaust air heat recovery technology:selecting typical meteorological year (TMY) data, adopting dynamic hourly simulation method, and processing the data with Excel software. Taking the exhaust air heat recovery device of a library project in Chongqing as an example, the study compares the uncertainty impacts of different TMY data on economic comparisons. Conclusion regarding the economic applicability of exhaust air heat recovery devices is drawn, along with proposed sources for selecting TMY data during analysis. The research outcomes can provide references for air conditioning system design.
Keywords:exhaust air heat recovery; economic comparison; recovery period; typical meteorological year (TMY) data; uncertainty analysis
