摘　　要：实验室检测墙体传热系数，通过对同一组蒸压加气混凝土砌块墙进行不同的冷室、热室温度设置得出的传热系数结果，并进行对比分析，提出可改变现今使用的冷室及热室温度设置，实现提高检测准确度的目的。福建省绝大部分地区冬季气温最低不低于-5℃，冬季室内人体感觉舒适的气温为18℃左右，依据GB／T13475—2008《绝热、稳态传热性质的测定、标定和防护热箱法》中的相关规定，将冷室、热室的温度分别设置改为-5℃和＋20℃。以适应福建省的实情。the laboratory testing of wall heat transfer coefficient, through to the same group of autoclaved aerated concrete block wall in different cold chamber, thermal room temperature setting came to the coefficient of heat transfer results, and comparative analysis, this paper puts forward can change now use cold chamber and hot chamber temperature setting, realize the purpose of improving detection accuracy. Most of the areas in fujian province winter temperature is not lower than the lowest - 5℃, winter indoor human feel comfortable temperature of 18℃ or so, according to GB/T 13475-2008 ＂adiabatic, steady state heat transfer properties measurement, calibration and protection hot box method by the relevant provisions, the cold chamber, the temperature of the hot chamber were set up to - 5℃ and ＋ 20℃, so as to adapt to the fujian province.
