Cold storage air curtains are usually only installed on the cold storage door connected to the outside atmosphere or normal temperature. It must be installed on the outer part of the cold storage to ensure that the nozzle and the door frame have a certain inclined angle (jet angle).
The jet angle should not be too large or too small, and the cold storage air curtain should be determined according to the height of the database and the temperature conditions in the library.When installing, it is necessary to pay attention to the level of the air curtain in the width of the door. The ends of the nozzle should grow 120-150mm longer than the door hole.Therefore, the model of the cold storage air screen must be selected according to the width of the cold storage door.
The opening and stop use of the itinerary of the cold storage air screen should be controlled when the door is fully turned on and stopped when the door is closed.The wind speed of the nozzle should be adjusted according to the height of the door and the temperature difference between the inside and outside of the library.
Some cold storage doors should pass through the suspension (such as the freezing room). The cold storage door in this kind of part was usually made of two fans. Dig a small hole in the two doors of the door for the suspension.The flat -opening door of the double fan is more troublesome, the insulation performance is poor, and there are many disadvantages.At present, the cold storage door that is currently suspended is generally used on the top of a single steel wood skeleton door on the frame of the frame.
The linkage that can automatically connect to and disconnect the suspension can prevent the "cold bridge" caused by the suspension through the suspension track, which improves the insulation performance of the door.Large through the guide rack on the guide track.When the door of the cold storage is turned on, the crank movement was moved by the rotation of the door axis, which drove the small door along the guide rail and opened the door.At the same time, the top rail on the small door will be disconnected.When the door is closed, the sliding of the small door will be opened at the same time, and the small door hole will be closed at the same time.
There is a distinction between left and right openings in the small door of the suspension rail. When making the air screen of the cold storage, you must pay attention to the relationship between the suspension direction of the suspension rack in the library and the direction of the connected door opening, so as not to waste the return workers.
The above is the precautions for the installation of the cold storage air screen. If you want to understand and learn more about related knowledge, please pay more attention to us ——
