这篇文章对用表面保温来加厚、改造冷库保温结构的方法的现实意义进行了研究,并比较了在冷库中用外加表面保温层与传统保温结构的实际效果。与传统保温办法不同的是,表面保温可以在冷库不停产的情况下施工,而且其费用只是等于拆除保温层再重新加厚保温层这传统保温方法费用的50%。用表面保温的方法对外墙的热力性能的改善 This article has studied the practical significance of the method of using surface insulation to thicken and reform the insulation structure of cold storage, and compared the actual effect of using external surface insulation layers and traditional insulation structures in cold storage. Different from the traditional insulation method, the surface insulation can be constructed without stopping production of the cold storage, and the cost thereof is only equal to 50% of the cost of the traditional insulation method of removing the insulation layer and re-thickening the insulation layer.
