严寒地区居住建筑气密性与室内热舒适性模拟研究

Simulation study on air tightness and indoor thermal comfort of residential buildings in severe cold areas

为完善适用于我国严寒地区居住建筑气密性与室内热舒适之间的关系,以沈阳市某小区一户住宅为模拟对象,对严寒地区居住建筑气密性与室内热舒适之间的关系进行探究。模拟分为冬季工况、夏季工况和过渡季工况,针对住宅内南北侧典型房间室内热舒适随气密性等级不同的变化情况进行模拟分析。研究发现,不同季节条件下,室内热舒适度随气密性变化情况不同,其中以冬季最为明显,过渡季次之,夏季建筑气密性的提升对室内热舒适的影响相对较小。

In order to improve the relationship between the airtightness of residential buildings and indoor thermal comfort in severe cold areas suitable for the specific conditions of our country. This paper takes a residential house in a residential area of Shenyang as the simulation object, and compares the airtightness of residential buildings and indoor thermal comfort in severe cold areas. The relationship between the two has been explored in detail. The simulation is divided into three conditions: winter working condition, summer working condition and transitional season working condition. The simulation analysis is carried out on the change of indoor thermal comfort of typical rooms on the north and south sides of the residence with different air tightness levels. The study found that under different seasons, indoor thermal comfort varies greatly with air tightness, the winter is the most obvious, followed by the transition season, in summer, the improvement of building air tightness has a smaller relatively relative impact on indoor thermal comfort.
