寒冷地区农村居住建筑供暖能耗计算方法研究
Calculation method of heating energy consumption for rural residential buildings in cold zone
摘要:
北方地区清洁取暖和“双碳”战略的实施,正加速推动农村居住建筑冬季供暖向清洁、低碳、高效的方式转变。供暖能耗计算是评估农村居住建筑供暖用能需求、标准节能率和既有农村居住建筑节能改造能效水平的主要途径。而目前的农村居住建筑相关标准及文献研究普遍采用城镇住宅的全室连续供暖能耗计算方法,与农村实际情况不符。本文基于农村现状调研,提出了一种符合寒冷地区农村居住建筑使用特征的分室间歇供暖能耗计算方法,并通过寒冷地区典型建筑在现状和现行国标围护结构条件下的分室间歇与全室连续供暖能耗模拟,对2种不同算法下的能耗和节能率进行了比较分析。
Abstract:
The implementation of the clean heating policy in the northern region and the carbon peaking and carbon neutrality strategy promotes the transformation of winter heating of rural residential buildings towards a clean, low-carbon, and efficient way. The calculation of heating energy consumption is an important basis for evaluating the heating energy demand of rural residential buildings, the energy-saving rate of standards, and the energy efficiency level of existing rural residential building energy-saving renovation. However, the current standards and literature research on rural residential buildings generally adopt the calculation method of energy consumption for whole room continuous heating, which is inconsistent with the current situation in rural areas. This paper proposes a new calculation method of energy consumption for individual room intermittent heating that is suitable for the use characteristics of rural residential buildings in cold zone based on rural current situation research. Under the different building envelope conditions that meet the current situation and the current national standard requirements respectively, the energy consumption and the relative energy-saving rate under two different methods are compared through the energy consumption simulation of individual room intermittent heating and whole room continuous heating in typical buildings in the cold zone.
