The cold storage door is the passage of goods in and out of the cold storage, which needs to be frequently switched, so it becomes the most vulnerable and damaged part of the cold storage. For the design, manufacture and installation quality of the cold storage door plays an extremely important role. At present, there are two main problems in the use of cold storage doors.
The cold storage door is the passage of goods in and out of the cold storage, which needs to be frequently switched, so it becomes the most vulnerable and damaged part of the cold storage. For the design, manufacture and installation quality of the cold storage door plays an extremely important role. At present, there are two main problems in the use of cold storage doors.
The first cold storage door damage problem;
The second is the power consumption of the cold storage door;
The first issue is particularly important. If the cold storage door is damaged, it will directly lead to the cold storage can not be used. In the use of cold storage, the damage of the cold storage door is mainly caused by the collision between the cold storage door and the cold storage door frame or the collision between the cold storage door and the transport vehicle in operation.
The energy consumption caused by cold storage door can not be ignored, mainly includes two aspects: direct cold loss, consumption of electric energy and cold storage door frame insulation heating required electric energy; indirect energy loss, such as cold storage door opening time is long, cold storage cold loss.
In order to solve the above problems, the classification of cold storage doors into three categories was studied. The first part is the study of the switch of the cold storage door to solve the problem of damage when the cold storage door is quickly closed. Using the speed control technology of the cold storage door based on the frequency conversion control technology, the cold storage door can run quickly during the closing process. At the end of the closing, the speed can be reduced to avoid collision damage to the refrigeration door, extend the service life of the refrigeration door, and avoid a large loss of cold capacity during the refrigeration process.
How to maintain the cold storage, how to maintain the cold storage has become a major business concern. Below we will introduce the design and installation methods of cold storage and some specific maintenance measures of cold storage.
Cold storage door is the throat that warehouse goods must pass through. When the warehouse door is opened, the hot and cold air inside and outside the warehouse is exchanged here, especially the temperature at the entrance changes frequently and violently. The walls, floors, and flat roofs around the door and its opening often experience flooding, dripping, frosting, and freezing, which cause the structure around the door to freeze and peel, the door seam to freeze, the door leaf, door frame, and sealing strip to be damaged, and the opening to fail. Therefore, the cold storage door, cold storage door, door opening and nearby walls, ground, etc. are the weak parts of the whole cold storage structure.
The cold storage door should be checked at any time, at least once a week, and the hinges should be oiled frequently. If it is found that the door is frozen or not closed tightly, it should be removed and repaired at any time. When there is a cold bridge in the door opening, it is necessary to repair or replace the insulating tape of the door opening immediately.
Finally, the cold storage is a sealed independent space, want to play its role, the significance of the cold storage door is self-evident.
