贵阳制冷设备和聊聊“冷桥”的作用及其施工建设指南

贵州制冷设备

在冷库中,所谓“冷桥”,实际上是传递热量的桥梁。贵州制冷设备提示在相邻不同库温的库房或库内与库外之问,由于建筑结构的联系构件或隔热层中断都会形成冷桥。例如管道穿墙,会因为管道穿墙引起稻壳层下沉.脱空,而造成冷桥。联系构件的冷桥是因材料的隔热性能较差,在冷桥处容易出现结冰、结霜现象,若不加以处理,热量便由此大量传入,冷库建设面积会逐渐扩大,接着会造成隔热层、结构构件损坏,甚至冷库受到破坏。

In cold storage, the so-called "cold bridge" is actually a bridge to transfer heat. The refrigeration equipment in Guizhou suggests that in the storeroom or library and outside the storeroom adjacent to the different storehouse temperatures, a cold bridge will be formed due to the interruption of the connection components of the building structure or the insulation layer. For example, if the pipeline goes through the wall, it will cause the rice husk layer to sink. The cold bridge of the connecting component is due to the poor heat insulation property of the material. It is easy to freeze and frosting at the cold bridge. If it is not treated, the heat will be introduced in large amount, the construction area of the cold storage will be gradually expanded, and the heat insulation layer, structural component will be damaged, and even the cold storage is damaged.

为防止冷桥产生,贵阳冷库厂家建设冷库时对可采用以下方法处理:

In order to prevent the generation of cold bridges, cold storage manufacturers can deal with the following problems when building cold storage.

1、贴顶法:小冷库中两个相邻的库房温差在5摄氏度以上时,间隔墙的隔热材料应与楼地面的隔热材料连通,在间隔墙的顶部,库温较高的一侧,在顶板底距离间隔墙1.2米的范围内做隔热层,并与隔热墙的隔热层连成一体,尽量减少连通相邻两库房的楼板、墙体构成的冷桥产生。

1, sticking top method: when the temperature difference of two adjacent storeroom in small cold storage is above 5 degrees Celsius, the insulation material of the partition wall should be connected with the heat insulation material on the floor, at the top of the wall and the high side of the reservoir temperature, the insulation layer within the range of 1.2 meters between the bottom of the top plate and the insulation layer of the insulation wall, so as to reduce the floor and wall of the adjacent two storeroom as far as possible. A cold bridge is produced.

2、隔热拉杆的处理:当采用钢筋拉杆来加固冷库时,应采用外形简单、断面较小的圆钢,以尽量减少热传导的影响。钢筋中设置硬木隔热块,以切断钢筋构成的冷桥。

2, heat insulation rod treatment: when the steel bars are used to reinforce the cold storage, it is necessary to use the round steel with simple shape and small section, so as to minimize the influence of heat conduction. The hardwood insulation block is set up in the steel bar to cut off the cold bridge made of steel bar.

3、穿墙管道的处理:穿墙管道要尽可能集中,预先留出走管孔洞,防止因穿墙打洞破坏隔热层。预留墙洞四周用木板封闭成盒状,并做好隔汽层,待冷库建设后,用软木或软木屑拌沥青填实。用稻壳做隔热层时,为防止木盒底部稻壳脱空,形成冷桥。

3, the treatment of wall through pipes: as far as possible, through the wall pipes, we should concentrate on the holes as far as possible, so as to prevent the insulation layer from breaking through the walls. The walls of the reserved walls are enclosed in boxes around the board, and the steam isolation layer is completed. After the cold store is built, it is filled with cork or cork chips. The use of rice husk insulation, to prevent the wooden box at the bottom of the rice husk separation, the formation of cold bridge.
