摘　　要：采用红外热像仪法对复合烧结多孔砌块墙体进行热工性能的测试,相关计算得出墙体的传热系数,并且将其热工参数值与由理论计算方法和热流计法得出的墙体热工参数值进行对比分析.结果表明,红外热像技术法测试得出墙体的传热系数值与采用热流计法检测墙体传热系数值基本相同,并且与理论计算值相差不大.验证了红外热像仪法应用于围护结构热工性能检测和能耗分析的可行性,从而为围护结构热工性能的检测提出便利快捷的方法,也为建筑围护结构热工性能的定量和定性的分析提供重要的参考价值.This paper analyses the thermal simulation regarding composite porous blocks by the way of the infrared technology, and calculates transfer coefficient of the wall. Making a theoretical calculation and experimental study by heat flow meter method on thermal properties of the wall. Then, the data of thermal insulating properties is analyzed. The results show that the thermal simulation of composite porous blocks wall were close to the data from the heat flow meter method and infrared technology. Comparing the infrared technology of test value and theoretical value, it is found that the test value is slightly larger than the theoretical value, but an insignificant difference. It shows that the right solution in the infrared thermal imaging method was applied to envelope thermal performance test and the feasibility of the analysis of energy consumption. And the paper puts forward a kind of convenient and efficient way of solving the thermal performance test of the wall.
