我校是五十年代建设的高等师范院校,现校舍建筑面积已达到二十三万平方米,原有供热管网的配置已不适应发展的需要,而且严重腐蚀老化,到了必须更新的时候了。1995年我们重新布置了全校热力管网,并且应用了当今先进的节能技术,经95～96年冬季供暖运行取得了很好的效果。主要采取了以下几项先进节能技术改造措施。 1.进行全校供热管网的热力平衡,水力平衡计算,将锅炉房向外供热的三条管网进行总的热量分配上的平衡,并考虑到近两三年内投入使用的房屋一并规划在内,确定了合理的出口管径和经济的流速,拆除管网中设置的所有管道泵和高扬程水泵。学校到1997年建筑面积
Our school is an advanced normal university built in the 1950s. The building area of the school building has reached 230,000 square meters. The original heating pipe network configuration has not been adapted to the needs of development, and it has been seriously corroded and aged to the point where it must be renewed. It’s time. In 1995, we re-arranged the whole school’s heating pipe network, and applied advanced energy-saving technologies today. After the heating operation in the winter of 1995-96, we achieved very good results. Mainly adopted the following several advanced energy-saving technological transformation measures. 1. Carry out thermal balance and water balance calculation of the whole school heating pipe network, balance the total heat distribution of the three pipe networks for external heating of the boiler room, and take into account the plans for the houses put into use within the next two to three years. Inside, a reasonable outlet pipe diameter and economic flow rate were determined, and all the pipeline pumps and high lift pump installed in the pipe network were removed. School to 1997 building area
