摘要
通过对北方严寒地区供热系统节能改造的研究,以张家口市某小区为例进行供热系统节能改造分析,对改造前后耗能量以及庭院管网输热能力等数据的整理分析。结果表明,改造后的供热系统庭院管网输热能力指标均符合相关规范规定,改造后冬季供暖用水量比改造前节省了23%,用电量比改造前节省了20%。供暖系统冬季供暖费用比改造前减少了40.56万元,改造后热用户认为供暖季室内温度较舒适和舒适的比例比改造前提高了58%,节能效果显著。
Based on the study of energy-saving renovation of heating system in severe cold area of north China,taking a residential district in Zhangjiakou City as an example,the energy consumption before and after the transformation and the heat transfer capacity of courtyard pipe network is analyzed.The results show that the heat transfer capacity indexes of the courtyard pipe network of the reformed heating system are in line with the relevant specifications.The water consumption of heating in winter after the transformation is 23%less than that before the transformation,and the power consumption is 20%less than that before the transformation.The winter heating cost of the heating system is reduced by 405600 yuan compared with that before the transformation.After the transformation,the users think the indoor temperature is more comfortable and the comfortable proportion in the heating season is increased by 58%compared with that before the transformation,and the energy-saving effect is remarkable.
