Research on heating characteristics of south and north based on typical meteorological data analysis
摘要:
针对南、北方供暖的需求差异,基于历年气象数据,综合考虑累年最冷月平均温度、供暖度日数HDD18、供暖期天数等多种因素,分析了中国南、北方8个典型城市的气候特征;同时结合需求调研和温度分布、波动差异对比情况,讨论了不同地区热负荷动态特性及负荷求解宜使用的方法;分析总结了南、北方地区的系统运行特征情况,给出了关于供暖系统设计、系统形式、运行策略的建议;并通过实际案例具体分析了供暖系统设置的适宜性问题,为后续供暖设计方法、参数确定,供暖方式选择和系统设置提供基础。
Abstract:
In view of the difference of heating demand between the south and the north, this paper analyses the climate characteristics of eight typical cities in the south and the north of China based on the meteorological data over the past years, taking into account the average temperature of the coldest month, the heating degree days HDD18, the number of heating days and other factors. At the same time, combined with the demand investigation and the difference comparison of temperature distribution and fluctuation, the dynamic characteristics of heating load in different regions and the appropriate method of load solving are discussed. The characteristics of the system operation in the south and the north are analysed, and some suggestions on the design, system form and operation strategy of the heating system are given. The paper analyses the suitability of the heating system setting through practical cases, which provides a basis for the subsequent heating design method, parameter determination, heating mode selection and system setting.
