利用红外热像仪现场检测牛舍围护结构的热工缺陷

Field detection of thermal defects in the building envelopes of cattle barns using an infrared thermal imager

为了探索泌乳牛舍建筑节能现场检测方法,提高牛舍工程验收和修缮水平,试验利用红外热像仪对两栋泌乳牛舍的热工缺陷进行了现场检测。结果表明:泌乳牛舍存在墙体保温材料脱落、断裂和空鼓,屋顶与墙壁交界处漏风,以及屋顶保温板接缝不严密等热工缺陷。说明红外热像仪是牛舍建筑节能现场检测的一种有效手段。

To explore the field detection method of the building energy - saving in lactating - cow barns, and improve the levels of project acceptance and maintenance for the barns, the field detection was conducted in the thermal defects of two lactating - cow barns using infrared thermal imager. The results showed that there were some thermal defects in the lactating - cow barns, including the exfoliation, fracture and hollowness of insulation materials on the wails, air leakage in the junction of the roofs and walls, imprecise seams between insulated boards of the roof and so on. The result indicates that the infrared thermal imager is an effective means for the field detection of the building energy - saving in the cattle barns.
