摘要
随着建筑节能水平的逐步提高,对建筑户门性能指标提出更高要求,其节能性能提升被作为重点进行研究。为研究户门节能性能提升技术,基于影响户门节能性能的主要因素建立户门传热模型,模拟计算户门的传热过程,计算户门的传热系数,研究分析不同模型与方案户门传热特点。门框、门扇搭接处与剪切面是户门传热的热桥部位,多道密封、门框与门扇作断桥处理是提升户门节能性能的有效技术途径。
With the gradual improvement of the energy saving level of the building, higher requirements are proposed for energy saving technology of building door, and its energy saving performance improvement is focused on. The heat transfer characteristics of the door are analyzed. Based on the main factors affecting the energy saving performance of the door,the door heat transfer model is established,the heat transfer process of the door is simulated,the heat transfer coefficient of the door is calculated,and the heat transfer characteristics of door and door with different models and schemes are studied and analyzed. The overlap and shear surface of door frame and door leaf are the heat bridge parts of the door,multi-channel seal and broken bridge treatment are effective ways to improve energy efficiency of door.
