摘   要：為了驗證采用模擬計算的方法研究金屬連接件對保溫與結構一體化墻體熱工性能影響的準確性與可靠性，首先依據(GB/T 13475—2008)《 絕熱穩態傳熱性質的測定標定和防護熱箱法》規定的防護熱箱法，制作實驗墻體，并在實驗臺上分別對錨入金屬連接件數量為 3 、6 和 9 個的保溫與結構一體化墻體進行了實驗研究 ，獲取了墻體的實測傳熱系數 。隨后利用Airpak 計算流體力學軟件建立與實驗研究相同的三組模型 ，并設置了相同的熱室與冷室溫度工況 ，分別計算其傳熱系數 。最后對實測結果與模擬結果進行了對比 。結果表明：錨入金屬連接件數量為 3 、6 和 9 個時的保溫與結構一體化墻體平均相對誤差分別為 4. 92% 、4. 69%和 3 . 96% ,  模擬計算誤差均在 5%范圍內，滿足工程計算要求。

Abstract：In order to verify the accuracy and reliability of using the method of simulation calculation to study the influence of metal connectors on the thermal performance of thermal insulation and structural integration wall, the experimental wall is first made according to the protective hot box method stipulated in "Determination and Calibration of Thermal Insulation Steady State Heat Transfer Properties and Protective hot box Method" (GB/T13475-2008). Experimental study was carried out on three, six and nine insulation and structural integration walls with anchored metal connectors on the experimental platform, and the measured heat transfer coefficients of the walls are obtained.Then Airpak computational fluid dynamics software is used to establish the same three groups of models as the experimental study, and set the same hot chamber and cold chamber temperature conditions, respectively, to calculate their heat transfer coefficients.Finally, the measured results are compared with the simulated ones.The results show that the average relative errors of insulation and structural integration wall are 4.92%, 4.69% and 3.96% respectively when the number of anchored metal connectors is 3, 6 and 9, and the simulation errors are all within 5%, which meet the requirements of engineering calculation.

Keywords:protective hot box method;metal metal connector;heat transfer coefficient;the relative error
