在实验室中研究了一种典型的隔热木框架住宅墙体结构的湿热性能。这项研究包括三种类型的蒸汽缓速器系统的影响，以及跨壁的零、正和负总压差的影响。暴露条件代表了北方冬季气候。研究中包括三种类型的蒸汽缓凝剂系统:聚乙烯薄膜（“优异”）、扁平乳胶漆（“较差”）和聚乙烯薄膜加电气插座（“点源缺陷”）。通过在墙体结构上施加各种正负压差，研究了空气渗透和渗出的影响。通过每天称量试验墙结构，测量水分增加（或损失）的总时间速率。定期拆卸试验壁，并确定累积水分的数量和位置。 通过观察绝缘层温度梯度的变化来测量热性能变化。单位:双引文:阿什雷交易，1985年，第91卷，第。你好，檀香山2A

The moisture and thermal performance of a typical insulated wood-framed residential wall structure was investigated in the laboratory. The study included the effects of three types of vapor retarder systems and the effects of zero, positive, and negative total pressure differences across the wall. Exposure conditions were representative of a northern winter climate.Three types of vapor retarder systems were included in the study: polyethylene film ("excellent"), flat latex paint ("poor"), and polyethylene film plus an electrical receptacle ("point-source defect"). The effects of air infiltration and exfiltration were investigated by imposing various negative and positive pressure differences on the wall structure.Overall time rates of moisture gain (or loss) were measured by weighing the test wall structure daily. Periodically the test wall was disassembled and the amount and location of the accumulated moisture determined. Thermal performance changes were measured by observing changes in the temperature gradient through the insulation layers.Units: Dual
