3. The cold storage board maintenance, pay attention to use, should avoid the collision and scratches of hard objects on the storage body. Because it may cause depression and corrosion of the library board, it will seriously reduce the local insulation performance of the library body.

4. Maintenance of the sealing parts of the cold storage. Since the prefabricated cold storage is composed of several thermal insulation boards, there are certain gaps between the boards. These gaps will be sealed with sealant during construction to prevent air and moisture from entering. Therefore, in use, some parts of the seal failure should be repaired in time.
5. Cold storage floor maintenance. Generally, the floor of small prefabricated cold storage uses thermal insulation boards. When using the cold storage, prevent a large amount of ice and water on the ground. If there is ice, do not use hard objects to beat or damage the ground during cleaning.
6. Check the insulation performance of the cold storage body, check whether there is condensed water around the cold storage, check whether the cold storage door opens flexibly, and the sealing effect of the cold storage door.
