摘要
目的分析北方既有非节能居住建筑供暖能耗总量巨大的问题,挖掘其中的节能潜力.方法对北方某城市2015—2016年采暖季采暖能耗进行了调研和实测,从供暖参数、间歇运行以及气候补偿3个方面对实际供暖的节能措施和运行效果进行分析.结果在低温采暖情况下,该地区既有非节能居住建筑能耗接近于节能50%的水平;末寒期间歇运行时,热水停供期间室内温度下降不超过2℃.结论散热器低温采暖以及末寒期间歇运行在该地区效果良好,有利于降低采暖能耗;采用气候补偿措施可以使供水温度随室外温度做出有效的调整,增强热网的气候适应性.
In order to excavate the energy saving potential from the huge energy consumption of existing non-energy-saving residential building,according to the information from a research on heating energy of 2015-2016 heating period in a city of northern China,the methods and effects in heating energy saving are analyzed from water temperature,intermittent running and climate compensation to know the effective approach for heating energy saving of residential building.The result shows that under low temperature heating situation,the building energy consumption in this area is close to the level of 50%.And at the end of heating season,when system runs intermittently,the room temperature will decline less than 2℃during the pause of heating.It is indicated that low-temperature heating of radiator and intermittent heating in the end of heating period running effectively and can benefit to energy reducing.Furthermore,climate compensation unit can make the water temperature changes with outdoor temperature more effectively,enhances the adaptability of heating network.
