【摘要】：既有居住建筑供暖系统分户热计量改造是建筑节能的重要环节,改造后的系统应能实现供暖节能又能满足用户热舒适度的要求。当前国内现行的供热计量方式在公平性、可操作性及社会接受程度等方面仍有不足,应进一步完善。对既有居住建筑供热计量技术的研究具有广阔的应用前景,本文主要是对既有居住建筑供暖系统改造技术的研究,开发符合我国国情并同时达到建筑节能、满足热用户舒适度的供热计量方法。本文分析国内现行的几种供热计量方法的热计量原理,阐述各种热计量方法的优势、不足及适用范围,归纳出供热计量系统的共性,并提出供热计量改造过程应满足的基本条件。结合现行的热计量技术并根据既有居住建筑供暖系统的特点,提出两种适用于既有居住建筑中垂直单管顺流式系统的供热计量改造方案,研究这两种方案的热量分配原理,建立相应热量分摊的数学模型,研究不同通断模式下相应的热量分摊方案。在本文两种热量分摊方案的基础上,开发与其匹配的供热计量监控管理系统,确定供热计量所需采集数据及采集方案、室温控制方案、数据传输方案。开发与监控系统相匹配的监控软件,用于实现用户认证、数据监控、远程管理等。
[Abstract]:Household heat metering reform of existing residential building heating system is an important link in building energy saving. The reformed system should be able to realize heating energy saving and meet the requirements of users' thermal comfort. The current domestic heating metering methods are still deficient in fairness, maneuverability and social acceptance, and should be further improved. The research on heating metering technology of existing residential buildings has a broad application prospect. This paper mainly studies the reconstruction technology of heating system of existing residential buildings, and the development conforms to the national conditions of our country and achieves the building energy saving at the same time. The heating metering method to satisfy the comfort of heat users. This paper analyzes the heat metering principle of several current heating metering methods in China, expounds the advantages, disadvantages and applicable scope of various heat metering methods, and sums up the generality of the heating metering system. And put forward the basic conditions that should be satisfied in the process of heating metering reform. Combined with the current heat metering technology and according to the characteristics of the heating system of the existing residential buildings, two kinds of heating metering retrofit schemes suitable for the vertical single-pipe downstream flow system in the existing residential buildings are put forward, and the heat distribution principle of the two schemes is studied. The mathematical model of heat allocation is established, and the corresponding heat allocation schemes under different on-off modes are studied. On the basis of the two heat allocation schemes in this paper, the monitoring and management system of heating metering is developed, and the data collection and collection scheme, room temperature control scheme and data transmission scheme for heating metering are determined. Development and monitoring system matching monitoring software for user authentication, data monitoring, remote management and so on.
