使用在冬季和夏季气候条件下运行的校准热箱，对两个高度隔热的住宅墙壁进行热阻测量。隔热良好的墙体由两个带交错框架的隔热木框架部分组成，其标称热阻为R-27 h)、ft2F/Btu（4.8 m2K/W）。超隔热墙在结构上是相同的，除了在两个木框架部分之间放置额外的隔热层，将墙的热阻增加到标称值R-39 hÌÌft2F/Btu（6.9 m2K/W）。将两个壁的实测热阻作为平均壁温的函数进行检查，并与使用ASHRAE平行路径法、ASHRAE等温平面法和导热系数随温度变化的有限差分模型进行的预测进行比较。使用ASHRAE方法和有限元方法，测量值和预测值之间获得了良好的一致性- 差异模型。当平均壁温高于40华氏度（4.4摄氏度）时，ASHRAE平行路径法倾向于预测过高，而ASHRAE等温平面法倾向于预测过低。研究了玻璃纤维毡隔热层压缩和钉子穿透对整体热阻的影响。单位:双引文:研讨会，ASHRAE交易，1986年，第92卷，pt。2B，波特兰，或

Thermal resistance measurements of two highly insulated residential walls are made using a calibrated hot box operated under winter and summer climatic conditions. The well-insulated wall consists of two insulated wood-frame sections with staggered framing, having a nominal thermal resistance of R-27 h•ft2F/Btu (4.8 m2K/W). The superinsulated wall is identical in construction, except for additional insulation placed between the two wood-frame sections increasing the wall thermal resistance to a nominal value of R-39 h•ft2F/Btu (6.9 m2K/W).The measured thermal resistance for both walls is examined as a function of mean wall temperature and compared with predictions using the ASHRAE parallel-path method, the ASHRAE isothermal-plane method, and a finite-difference model with temperature-dependent thermal conductivities. Good agreement between measured and predicted values is obtained using both ASHRAE methods and the finite-difference model. At mean wall temperatures above 40 F (4.4°C), the ASHRAE parallel-path method tends to overpredict, while the ASHRAE isothermal-plane method tends to underpredict the overall thermal resistance. The effects of the compression of glassfiber blanket insulation and nail penetrations on the overall thermal resistance are investigated.Units: Dual
