貴陽制冷設備和聊聊“冷橋”的作用及其施工建設指南

貴州制冷設備

在冷庫中,所謂“冷橋”,實際上是傳遞熱量的橋梁。貴州制冷設備提示在相鄰不同庫溫的庫房或庫內與庫外之問,由于建筑結構的聯系構件或隔熱層中斷都會形成冷橋。例如管道穿墻,會因為管道穿墻引起稻殼層下沉.脫空,而造成冷橋。聯系構件的冷橋是因材料的隔熱性能較差,在冷橋處容易出現結冰、結霜現象,若不加以處理,熱量便由此大量傳入,冷庫建設面積會逐漸擴大,接著會造成隔熱層、結構構件損壞,甚至冷庫受到破壞。

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.

為防止冷橋產生,貴陽冷庫廠家建設冷庫時對可采用以下方法處理:

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

1、貼頂法:小冷庫中兩個相鄰的庫房溫差在5攝氏度以上時,間隔墻的隔熱材料應與樓地面的隔熱材料連通,在間隔墻的頂部,庫溫較高的一側,在頂板底距離間隔墻1.2米的范圍內做隔熱層,并與隔熱墻的隔熱層連成一體,盡量減少連通相鄰兩庫房的樓板、墻體構成的冷橋產生。

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、隔熱拉桿的處理:當采用鋼筋拉桿來加固冷庫時,應采用外形簡單、斷面較小的圓鋼,以盡量減少熱傳導的影響。鋼筋中設置硬木隔熱塊,以切斷鋼筋構成的冷橋。

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、穿墻管道的處理:穿墻管道要盡可能集中,預先留出走管孔洞,防止因穿墻打洞破壞隔熱層。預留墻洞四周用木板封閉成盒狀,并做好隔汽層,待冷庫建設后,用軟木或軟木屑拌瀝青填實。用稻殼做隔熱層時,為防止木盒底部稻殼脫空,形成冷橋。

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.
