Description

Cold storage system, gas film building and emergency door structure

Technical field

The invention relates to the technical field of air film construction, in particular to a cold storage system, a gas film building and an emergency door structure thereof.

Background technique

With its low cost, easy disassembly and assembly, and light weight, gas film construction is increasingly used in all walks of life. Some air film buildings will be equipped with emergency doors. The emergency doors are only used under special circumstances. When the emergency doors are opened, the buildings are directly connected inside and outside, which will cause a large amount of gas leakage.

Since the emergency door does not open very often, this film building has little effect on conventional applications. However, if the air film building is applied to the cold storage system, a large amount of cold air will leak when the emergency door is opened, which causes the temperature inside the building to rise, which easily causes the loss of frozen goods in the cold storage. If the emergency door is set to the same structure as the main entrance and exit door, it will bring unnecessary high cost and lead to an extension of the construction period.

The refrigerating apparatus is disposed in the air film main body 100, or the cold air outlet of the refrigerating apparatus communicates with the inside of the air film main body 100.

Under normal circumstances, the emergency door structure 200 will not open. The traditional emergency door has only one door. Since the door seam cannot be completely sealed, there will be a gap between the door and the door frame, so even in the closed state, The temperature performance will be poor. In the embodiment, the two door structures of the first door assembly 240 and the second door assembly 260 are adopted, on the one hand, the heat loss near the door assembly can be reduced, and on the other hand, the air pressure forms a step, and the pressure difference between the inside and the outside of each door is compared with the conventional one. The structure of a door can be reduced by about half. In the state of not opening, the above-mentioned emergency door structure 200 will be greatly reduced in air leakage compared with the conventional emergency door, so the heat preservation performance will be more excellent. The above-mentioned gas film building 10 is applied to a cold storage system to meet the requirements for maintaining the temperature.
