建筑物热性能.建筑物空气渗透率测定.风扇增压法 - Not only including the heat transfer of envelop , it is also considered air infiltration inner heat gain lighting energy efficiency ratio for energy consume calculation
建筑能耗计算不仅考虑围护结构的传热，而且要包括空气渗透传热、内部得热、室内照明、空调采暖设备的能效比等因素。 - At present , national standards including graduation and test method for thermal insulating properties of windows ( gb8484 - 2002 ) and graduation and test method for air infiltration of windows ( gb71017 - 2002 ) regulate the two indexes of thermal transmittance and air infiltration of windows , but the standards don ’ t involve the test method for building shading performance of windows
现行国家标准包括《建筑外窗保温性能分级及其检测方法》 ( gb8484 - 2002 )和《建筑外窗空气渗透性能分级及其检测方法》 ( gb71017 - 2002 )中对窗户的传热系数和空气渗透量这两项指标做了规定,但是没有涉及到建筑遮阳性能的检测。 - Two typical examples analyses are conducted for the average conditions both of winter and summer climates under vapor diffusion and air leakage . a further discussion is set forth to determine the main factors that the moisture accumulation in wall is affected . it is found that the factors are the relative humidity at the wall surface , indoor temperature , permeability , air pressure difference and rate of the infiltrative or exfiltrative airflow
本文首先研究了墙体内的湿气迁移过程，详细分析了湿积累现象形成的原因，通过对夏、冬两季平均气候下墙内温度、水蒸气压力、相对湿度及湿积累在仅有扩散、扩散与空气渗透同时存在等情况所作的具体计算，发现墙内、外表面的相对湿度、室内温度、渗透率、空气压差以及空气的渗流速度是影响墙内湿积累的主要因素。
