寒冷地区某污水源热泵系统供暖季运行效果与节能减排分析
|
摘要
热泵技术是当今建筑节能的重要技术之一,为了探究其实际的运行效果和节能减排量,对寒冷地区某办公建筑的污水源热泵系统进行研究,通过实地调研2016—2017年度冬季该系统运行性能的数据,分析了该污水源热泵系统在冬季的运行效果,并与冬季采用传统燃煤锅炉供暖方式进行比较,得到该系统供暖季的机组平均COP和系统平均EER分别为2.82和2.2,较传统燃煤锅炉供暖方式可以节省标煤260.8t,减少CO_2排放量为717.2t、SO_x排放量为1.04t、NO_x排放量为7.8t、粉尘量为5.2t。
Heat pump technology is one of the most important technologies for building energy conservation today. In order to explore its actual operation effect, energy saving and emission reduction, the sewage source heat pump system of an office building in the cold area is studied. Through field research on the system performance in the winter of 2016-2017, the operation effect of the sewage-source heat pump system in winter was analyzed, and compared with the traditional coal-fired boiler heating method in winter. The average COP and EER of the system in heating season are 2.82 and 2.2, respectively. It compares with the traditional coal-fired boiler heating mode, the system can save 260.8 t of standard coal, 717.2 t of CO_2 emission, 1.04 t of SO_x emission, 7.8 t of NOx emission and 5.2 t of dust emission.
