Methodology of determining minimum energy efficiency requirements for chillers
摘要：
基于公共建筑整体节能目标，综合考虑用能设备的经济性和技术可行性，提出了冷水机组能效限值确定方法。建立了冷水机组综合性能曲线数学模型和初投资模型。通过对各气候区不同建筑类型空调系统能耗的优化计算，得到了我国不同气候区冷水机组的能效限值，并对其能效水平及节能效果进行了综合分析。
Abstract：
On the basis of the overall energy saving target for the public buildings, proposes a new method to determine the energy efficiency of chillers by considering the economics and technical feasibility of the equipments. Establishes the mathematical model and initial investiment model for the comprchensive performance of the chillers. By optimal simulation for energy consumption of public buildings with different types in different climate zones, obtains the minimum energy efficiency requirements of chillers in different climate zones, and conducts a comprchensive analysis of the minimum energy efficiency and the energy-saving effect.
Keywords:chiller, minimum energy efficiency requirement, saving to investment ratio (SIR), comprehensive performance curve, energy-saving effect
