为了节约建筑采暖能耗,必须提高建筑外围护结构的保温性能,以减少由外围护结构散失的热量。然而,通过建筑外围护结构各个部件的传热耗热量并不均衡,如何结合当地实际情况,经济合理地选择建筑外围护结构各个部件的传热系数,选用合适的构件,达到50%建筑节能要求,成为实施节能工作 In order to save the energy consumption of building heating, we must improve the insulation performance of the building envelope to reduce the heat loss from the envelope. However, the heat transfer and heat loss of the various components of the building envelope are not balanced. How to select the heat transfer coefficient of each component of the building envelope in an economical and reasonable way according to the actual conditions in the area? Energy-saving requirements, as the implementation of energy-saving work
