【摘要】 随着我国节能减排工作的不断深入,供热体制改革也成为了其中的焦点之一。实施供热计量收费是供热体制改革的重要内容。热量计量收费是其中重要的组成部分。现有的热量计量方式中的主要设备是户用热量表和热分配表。热量表都需要使用流量计,在我国的供暖系统的水质比较差的情况下容易导致流量计损坏并产生计量误差。传统的热分配表虽然经济、易安装,但是由于抄表和计量精度的问题在我国没有得到大规模应用。因此能否找到新的分配计量方法,使热量分配计量更加准确便捷是本课题研究的主要任务。本课题的主要研究内容包括:对利用温差电压法分配热量进行可行性论证。建立了散热器的数学模型,推导出散热器进口温度与散热器表面附近室温温差所产生电压值与散热器流量之间的函数关系。搭建了一个实际的供暖运行环境,通过单个多种规格的散热器的实验后,验证了数学模型的正确性;在此基础上,将实验环境分成三个独立的密闭空间,分别用三个相同种类相同规格的散热器以及相同种类不同规格的散热器来模拟热量分配,同时用精度较高的超声波流量计来测量实际流量,用实际热量分配与模拟分配进行对比,并分析了误差原因。课题的计量方法和装置分别申请了国家发明专利和实用新型专利,其中实用新型专利已获授权,发明专利审核中。本课题的研究将为深化供热体制改革实现住宅用户分户热量计量提供积极的帮助。更多还原

【Abstract】 Along with the energy-saving and ejection-decreasing taking deeply, the reformation of heating system has been one of the focuses. The heat measurement is an important part of the reformation of heating system.In the currently measurements, the central equipment is heat meter, and almost all heat meters need flow meter, but hot water quality in our country‘s hot water supply system is bad, So the flow meter is very easy to be damaged and this can cause measurement error. The traditional heat cost allocators are easy setting an economical, but haven’t used in our country for the reason of measurement and precision. Then we will research how to find a new method for hear allocation, so we can measure the heat allocation accurately and conveniently.The mostly research contents of my project contain: set up the mathematic model of the radiator, and then established the function of the flow and the temperature difference. After the experiment of actual radiator, the results of experiment validate the validity of our model; on the based of the research, we divided the experiment environment into three obturation rooms, then tested the error about the method. My project has obtained the national layout-design invention patent and the utility model patent. The research of this project will make a well foundation for the heat measurement of condo house.更多还原
