Cold storage doors have gradually covered the whole country. With the rapid development of China's economy, refrigeration equipment has entered supermarkets, commerce, industry and agriculture and other areas closely related to our lives. However, due to the domestic refrigeration industry started later than developed countries, mechanized management is not yet mature.

The importance of snow palace recommend cold storage door in the construction of cold storage:
The domestic labor price of cold storage door manufacturers is generally low, and the storage capacity of many freezers is relatively small. Therefore, manual operation and manual operation are generally used, or manual and hydraulic vehicles are used. Electric forklifts are rarely used, and there are few automatic opening and closing devices for freezing doors.
There are two main problems in the use of cold storage doors: first, the cold storage door is damaged. Because the cold storage door needs to be opened and closed frequently, the shell structure of the cold storage is very vulnerable to cooling damage. When the cold storage door is closed too fast, the cold storage door is easily damaged. Transport vehicles when the cold storage door hits the door frame or the cold storage door runs.
The power consumption problem of cold storage door and the energy consumption problem caused by cold storage door can not be ignored, mainly including two aspects: direct energy consumption, such as motor rotation, required electric energy cold storage door frame insulation heating; Cold storage door open time is too long, cold storage loss and other indirect energy consumption loss. It can be seen that the cold storage door is of great significance to the overall performance of the cold storage.
Roll in constant temperature and humidity and ambient temperature and humidity changes, often cold storage inside and outside temperature difference is usually 40~70 ℃. When the external storage is at higher temperature and steam pressure, hot air enters the cold storage through the cold storage door. The intrusion of heat and water vapor not only directly increases the heat load of refrigeration, but also reduces the evaporation efficiency due to the increase of frost thickness of the evaporator. At the same time, the cold and hot air near the cold storage door and the building structure, floor and thermal insulation materials are seriously damaged, even making the freezing wall of the cold storage brittle expansion, greatly reducing the service life of the thermal insulation structure, increase the energy consumption of cold storage. Poor performance or poor management of cold storage doors directly leads to increased energy consumption. Cold storage door performance is poor, energy consumption increased by more than 15%.
