摘要
本文首先介绍了我国供热收费的现状,指出了现阶段我国热价制定及收取的不合理性,介绍了国外热计量实施及供热收费发展的情况,然后探讨了热价的构成,提出了实行热计量后,我国热价制定和热费收取的基本原则。
     本文分析了影响住宅住户耗热量的影响因素,以住宅建筑为研究对象,模拟分析了住宅建筑的楼层位置、朝向以及建筑围护结构和窗墙比对住户耗热量的影响。通过本文的研究发现住宅的底层住户、顶层住户以及有外墙的住户的耗热量远高于住宅中心用户的耗热量。在考虑上述情况的基础上,把用于住宅建筑热费结算的楼栋热表数据分为公共耗热量和非公共耗热量两部分。屋顶、地面、外墙这些围护结构引起的耗热量作为公共耗热量,并按采暖面积分摊到各户;而非公共耗热量部分以用户基准耗热量为依据对各户分摊热量。
     文中以合肥某小区住宅4#楼为例,介绍了热表读数中公共耗热量系数的提取计算方法,通过Dest软件模拟计算确定其公共耗热量系数,并以各户热表读数为依据进行分摊。研究结果表明本分摊方法有助于热计量收费的公正和合理。
Firstly, we introduce the condition of heating cost in our country, at present, and point out that the price and the cost of heating is not unreasonable, and then introduce the practice of the heating meter and the development of the heating billing abroad. At last, we study the construction of the heating price and bring up the basic principle that we establish the price and collect the cost when we practice theheating meter.
     The thesis introduces the factors which influce the household consumption and and analyze the influence of foor position、building towards and window-wall ratio which impact on household heat consumption is raised in simulating the residential buildings. Through the thesis ,we discover that :the heat consumption of the lowest story door, highest story door and the door stick to gable wall is more than the center door of the building. On the base of comprehensive survey at factors mentioned above,the totall building heat consumption were divided into the communal heat consumption and the variable heat consumption.he heat consumption cased by building envelopes such as gable, ground and staircase is defined as the communal heat consumption, are abstracted and allocated averagely according area and added to the variable heating load calculation ,and taking for charging heating load.
     The thesis aims at 4# residence project of in one Hefei small region, introduces academic calculating formulas of all the abstracted coefficient of the communal heating load calculation from the total heating load calculation in household building.Through the soft Dest ,find out the abstracted coefficient of the communal heating load,and revise the reading from the meter.the result testify the theory is reasonal and fairness heating-metering and charging system.
