What is the necessity of the cold storage door of the snow palace recommend cold storage?
At present, there are two key problems in the whole application process of electric refrigeration door:

First, the electric refrigerator door is difficult to destroy. Because the cold storage door must be frequently opened and closed, it has become the most vulnerable position in the structure of the cold storage rack. When the refrigerator door is closed at a high speed, it will hit the door frame of the refrigerator, or the refrigerator door will collide with the transport vehicle during operation, which is most likely to cause damage. When the cold storage door is seriously damaged, the cold storage can be immediately unusable. Cold storage board manufacturers

Second, the electromagnetic energy consumption of electric refrigeration doors cannot be ignored, and the heat consumption of electric refrigeration doors cannot be ignored. The key includes two aspects, such as the electromagnetic energy consumed by the motor rotation and the electromagnetic energy required for the insulation and heating of the door frame of the electric cold storage; indirect kinetic energy loss, such as the opening time of the electric cold storage door is too long, and the cooling capacity of the cold storage is outflow. It is not difficult to see that the cold storage door has a vital practical significance to the overall performance index of the cold storage.
For a long time, the warehouse has been in a natural environment with frequent changes in ultra-low temperature, high temperature, temperature and environmental humidity, and the temperature difference between the inside and outside of the warehouse generally reaches 40~70. The temperature outside the warehouse is high and the water vapor pressure is too high. When the outside warm air enters the warehouse according to the cold storage door, the invasion of calorific value and water vapor not only immediately increases the cooling heat consumption, but also reduces the volatilization efficiency due to the thin and thick frost layer of the air conditioning evaporator.
In addition, the cold and hot gases in the electric cold storage door and the surrounding building structure, epoxy floor and thermal insulation materials are seriously damaged, and even lead to the freezing and expansion of the cold storage wall, which greatly reduces the service life of the rack structure and increases the energy consumption of the cold storage. Poor refrigeration door characteristics or improper management methods will immediately increase energy consumption, and poor refrigeration door characteristics can increase energy consumption by 15% or even a lot.
When the refrigerator door manufacturer opens the door, the higher the aspect ratio of the refrigerator door manufacturer, the greater the warm air entering the warehouse, and the greater the cooling capacity loss; however, the greater the total width of the refrigerator door, the longer the opening time of the refrigerator door, the greater the power consumption of the motor. Therefore, only by finding the appropriate ratio of height to width to total width can the best practical effect of environmental protection and energy saving be achieved.
That is, when the cold storage door manufacturer opens, the wet and cold damage is positively related to the total area of the cold storage door. Therefore, under the premise of considering the product specifications and sales volume, the refrigerator door manufacturer should effectively design the plan to minimize the total area of the refrigerator door manufacturer and reduce the damage to the refrigeration capacity. The key raw materials for cold storage doors are generally cold storage insulation boards made of high-pressure polyethylene and polystyrene.
However, due to the high ductility and compressive strength of polyurethane materials, excellent wear resistance, abrasion resistance, water resistance, fatigue resistance and vibration resistance, the best feature is now polyurethane color steel sandwich panels. Cold storage door manufacturers try to choose polyurethane cold storage insulation board such as pipe abalone polyurethane cold storage insulation board, and try to avoid the frequency and time of opening the door and the outflow of cooling capacity.
