Optimal research on secondary network temperature of central heating systems
摘要：
目前我国集中供热系统的二次网供回水温度存在设计参数高、运行参数低的现象，同时集中供热系统应用形式呈现出多样性的特点。如何在不同的燃料价格和设备基价背景下，优化选择二次网供暖设计参数值得深入研究。调研了国内外集中供热系统的二次网供暖设计参数和我国部分城市二次网供暖运行参数情况，建立了二次网供暖设计参数影响集中供热系统技术经济性的分析模型，通过模拟分析得出了散热器和地面供暖系统的二次网供暖优化设计参数。
Abstract：
Considering the status of higher design temperature parameters and lower operation temperature parameters in the secondary heating network of central heating systems with a diversity of application forms at present, deems it worthy to further study for optimizing the design temperature parameters of the network in different price conditions of fuel and devices. Investigates the design temperature parameters at home and abroad and the operation temperature parameters in some cities of China. Establishes a mathematical model for analysing influences of the design parameters on the cost-effectiveness of central heating systems. Obtains the optimal design temperature parameters for radiator and floor panel heating systems by simulation and analysis.
