《公共建筑节能改造节能量修正计算方法》:本文关于公共建筑论文范文,可以做为相关论文参考文献,与写作提纲思路参考。

摘 要:

针对当前公共建筑节能改造节能量确定方法尚不完善的现状,提出了一种新的节能量修正计算方法,即以改造前建筑为基准的节能量修正模型,包括4个修正系数和3个计算式,4个修正系数分别为气象修正系数、室内热环境修正系数、内部负荷修正系数和运行时间修正系数,3个计算式为采暖节能量计算、空调节能量计算和总节能量计算.以天津市某大型办公建筑节能改造项目为例,采用节能量修正模型,得到修正节能量,此节能量保证了比较条件的一致性.通过比较修正节能量和改造前后能耗直接相减的节能量,修正节能量计算方法引起10.23%的节能量差别,从而证明了修正的必要性.通过和模拟软件计算结果的对比,差别为3.03%,在10%的可接受范围内,验证了该节能量修正计算方法的准确性.

Abstract:

There exists imperfections of the methods for energy conservation verification of the energy efficiency retrofit projects. A new energy conservation verification method was developed by creating energy conversion correction model and four correction coefficients and three calculation formulas were involved, The four correction coefficients were outdoor weather correction coefficient, indoor environmental correction coefficient, internal load correction coefficient and performance period correction coefficient. The three calculation formulas were heating energy conversion calculation, air-conditioning energy conversion calculation and total energy conversion calculation. The energy conversion correction model was adopted to analysis the energy conservation of an office building located in Tianjin to demonstrate the reliability of the correction model and the feasibility of the verification method, and the corrected energy conversion based on consistent conditions before and after retrofit was obtained. 10.23% difference between the corrected energy conversion and the direct energy conversion exists indicating that the correction energy conversion is necessary. The energy conservation difference of 3.03% the calculation result of energy simulation software verified the accuracy of the new verification method.

近年来,节能改造作为降低建筑能耗的有效手段被广泛实施[1],改造完成后,需对改造项目进行节能量的核定.国际通用的节能量检测和验证标准有《国际性能节能效果的测量和验证协议》(IPMVP)[2]、Measurement & Verification for Federal Energy Projects (M&V)[3]和ASHRAE Guideline14-2002[4].这些方法依赖于主观评价,被认为不准确[5].在中国,节能量为改造前后能耗直接相减[6].事实上,改造前后建筑所处条件不同,缺乏可比性.目前常见处理方法有两种:一是增加调整项[7],调整量通过建立回归模型得出 [8],而回归模型的准确性取决于数据的完善程度;另一种方法是动态能耗模拟软件[9],通过设置使改造前后建筑处于相同的内外部条件下[10].但模型建筑需要根据实际情况设定,许多参数(如人员密度、设备工作时间等)的获得需要经过长时间的大量调研,且实际情况的随机性很强[11],软件模拟值的真实性受限.改造建筑很多时,模拟工作量大时间长,因此模拟软件更适合单栋建筑节能改造的设计,不适合大规模改造建筑节能量确定.综上,需要提出更准确、更实用的节能量计算方法.
