                    科研项目

                    红外热像技术在建筑节能检测中的应用研究

                    项目时间: 完成情况:


                    该项目研究首先从红外热像仪测温原理入手,采取相应的对策后,将红外测温由定性提高到了定量。热电偶法测量围护结构的耗热量无法避免“以点代面”的做法。将红外热像仪测温方法与点温法相结合,可以有效提高测温精度。采用红外热像法测量围护结构耗热量及传热系数,分析了测量精度及误差,验证了该方法的可行性。采用红外热像法测量围护结构热工缺陷,结合实际工程的红外热像图分析,提出了定量的评价指标。对于室内热工缺陷,用围护结构内表面相对温差和相对面积双参数来评价;对于室外热工缺陷,用围护结构外表面主体区域平均温度与缺陷区域最高(最低)温度温差和相对面积双参数来评价。
