【摘要】：国外供热计量技术比较成熟,自动化水平程度高,运行管理方便。我国从上世纪引入热计量概念,经过多年的摸索、试点、推广,热计量技术在中国发展日益成熟。然而仍有部分供热系统无计量、无调节。本文通过对热计量理论方法的研究,结合燕山石化民用既有建筑热计量改造项目研究,对新建或既有建筑热计量改造起借鉴意义。本文首先调研燕山石化项目的热源、热网、末端用户概况,绘制供热系统图,制作设备清单表,书写调研报告。其次根据调研结果制定热计量改造方案,分析比较燕山石化民用建有建筑改造适宜的热计量方法,综合考虑多种热计量方法的适用性、经济性。最后,确定燕山石化民用既有建筑项目改造采用散热器热分配计法,开始选取热计量设备,绘制系统改造图,定期向改造小区用户宣传热计量改造技术、政策,并严格按照供热计量技术导则改造。在采暖初期,对燕山石化供热系统进行水力平衡、水泵效率、锅炉效率测试与分析。根据测试与分析结果,采取相应的主要调节措施：初步调节管网水力平衡,并应用等温降法局部修正水力平衡；根据室外温度,制定水泵变频策略；热源锅炉采用热量调节法,实现按需供热,提高锅炉运行效率。在采暖末期,统计分析燕山石化热计量改造小区整个采暖季的能耗、热费情况。
[Abstract]:The foreign heating metering technology is mature, the level of automation is high, and the operation management is convenient. From 0th century, our country introduced the concept of heat metering, after many years of exploration, pilot, popularizing, The technology of heat metering is maturing day by day in China. However, there are still some heating systems without metering and regulating. Through the research of the theory and method of heat metering, this paper studies the project of thermal metering transformation of existing buildings in Yanshan Petrochemical Company. This paper first investigates the heat source, heat network and terminal users of Yanshan Petrochemical Project, draws the chart of heating system, and makes the list list of equipment. Secondly, according to the results of the investigation, the scheme of heat metering transformation is worked out, and the suitable heat metering methods for building reconstruction of Yanshan Petrochemical Company are analyzed and compared, and the applicability and economy of various heat metering methods are considered synthetically. Finally, It is determined that Yanshan Petrochemical Company has adopted the radiator thermal distribution method in the reconstruction of existing civil construction projects, started to select the heat metering equipment, drew the system transformation diagram, and regularly publicized the heat metering transformation technology and policies to the users of the revamped residential areas. In the initial stage of heating, the hydraulic balance, pump efficiency and boiler efficiency of Yanshan Petrochemical heating system are tested and analyzed. The corresponding main regulation measures are adopted: primary regulation of pipe network hydraulic balance and partial modification of hydraulic balance by isothermal drop method; formulation of frequency conversion strategy of water pump according to outdoor temperature; heat source boiler using heat regulation method to realize heat supply on demand. At the end of heating, the energy consumption and heat cost of the whole heating season in Yanshan Petrochemical heat metering reform district were analyzed statistically.
