我区在建筑节能方面取得了很大的进步,但也存在一些问题。维护结构的热工性能,在施工中存在一些问题。在提高采暖、空调设备能效比方面问题比较复杂一些。①户内系统为水平单管串联系统;②地板辐射采暖室内温度感偏高;③室外采暖系统无论是一次管网还是二次管网水力、热力不平衡现象都非常严重;④对既有居住建筑节能改造;⑤计量供热方式选择。
My district has made great progress in building energy efficiency, but there are also some problems. Maintain the thermal performance of the structure, there are some problems in the construction. In improving heating, air conditioning and energy efficiency equipment more complex issues. ① Indoor system is a horizontal single-tube series system; ② floor radiant heating room temperature is high; ③ outdoor heating system whether it is a pipe network or secondary pipe network hydraulic and thermal imbalances are very serious; ④ pairs of existing residence Energy-saving building; ⑤ measurement of heating options.
