Description

TECHNICAL FIELD

[0001] The application relates to the technical field of refrigeration systems, in particular to a double-door-hold cold storage device. BACKGROUND

[0002] The main function of a cold storage is to store food, dairy products, meat, aquatic products, poultry, fruits and vegetables, cold drinks, flowers, plants, tea, medicines, chemical raw materials, electronic instruments and the like at constant temperature. The cold storage is actually a low-temperature combined air conditioning equipment. The cold storage (cold storage) also belongs to a kind of refrigeration machine compared with the refrigerator. The refrigeration area is much larger, but they have the same refrigeration principle.

[0003] As shown in the cold storage shown in Figure 1 and Figure 2 , the conventional design of the cold storage has one door hold, and the cold storage inside and outside the cold storage are separated by a cold storage insulation door. When the goods are frequently in and out, the cold storage door is open for a long time, especially when there is a large difference between the outdoor temperature and the cold storage environment temperature, a large amount of high-temperature gas from the outside is easy to enter the cold storage and produce a large amount of ice-forming factor after meeting the refrigerant; at the same time, under the condition of too high humidity in the cold storage, the moisture in the air is easy to condense on the condenser and the fan blades with low temperature and form ice layer.

[0004] The cold storage fan is an important component of the cold storage refrigeration system. When the ice layer accumulates more and more, the fan blades will break when hitting the ice layer, which will cause the fan to be unable to work normally. The fan is a key equipment for keeping the air circulation in the cold storage. If the fan fails or does not work normally, the cold storage cannot be used, and therefore needs to be improved. CONTENT OF THE INVENTION

[0033] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Without conflict, those skilled in the art can combine and integrate the different embodiments or examples shown in this application, as well as the features of those embodiments or examples.

[0034] This application discloses a double-door cold storage device. (Refer to...) Figure 3 and Figure 4 The double-door cold storage unit includes a cold storage body 1, a first doorway 2, a second doorway 3, a cold storage insulated door 4, and a high-speed roller shutter door 5. The first doorway 2 is installed outside the cold storage body 1, and the second doorway 3 is installed inside the cold storage body 1 and communicates with it. The first doorway 2 and the second doorway 3 are connected, and the cold storage insulated door 4 is installed at the connection point between the first doorway 2 and the second doorway 3. In this embodiment, the cold storage insulated door 4 adopts a horizontal sliding structure, allowing workers to apply pushing force to open it, making it easier for workers carrying items to pass through and providing a smoother passage experience. The high-speed roller shutter door 5 is installed on the first doorway 2 and is used to control the airflow between the first doorway 2 and the outside air.

[0035] In the cold storage design, a double-layer door pit structure is adopted, and a buffer zone is constructed in the middle, which can effectively block the invasion of external hot and humid air into the cold storage main body 1, thereby significantly reducing the loss of cold quantity. In addition, the quick opening and closing of the roller shutter door can greatly shorten the opening and closing time of the door, thereby reducing the amount of hot air entering the first door pit 2, and ultimately achieving the purpose of reducing the exchange of cold and hot air.

[0036] Specifically, the first door pit 2 and the second door pit 3 are both made of thermal insulation materials, such as polyurethane sandwich panels, to reduce the conduction speed of heat and reduce energy consumption. The second door pit 3 is also provided with a vertical curtain 6, which is located at the communication position between the second door pit 3 and the cold storage main body 1. The vertical curtain 6 can effectively reduce the heat transfer between the inside and outside of the cold storage, prevent external hot air from entering the cold storage, and prevent cold air from leaking out of the cold storage, thereby maintaining a stable low-temperature environment inside the cold storage, reducing the energy consumption of the refrigeration equipment, and achieving the effect of energy saving and emission reduction.

[0037] The vertical curtain 6 is made of transparent low-temperature resistant material, such as PVC. The low-temperature resistant vertical curtain 6 is made of special material and formula, which can maintain softness and toughness at very low temperature, and is not easy to become brittle or break, which is convenient to use and can prolong the service life. At the same time, the vertical curtain 6 adopts a magnetic structure, and the automatic adsorption design of the magnetic vertical curtain 6 makes the door curtain open and close quickly without manual pulling, which is especially suitable for the situation that the staff is carrying objects or in a hurry, and brings great convenience to the operation of the cold storage.

[0038] In this embodiment, the second door pit 3 is set as a high and large space structure, the length of the second door pit 3 is 6000mm, the width of the second door pit 3 is 3000mm, and the height of the second door pit 3 is 1500mm. In addition, the surface of the second door pit 3 is also provided with a color steel plate 7, which is used to contact with the external hot and humid air, and the thickness of the color steel plate 7 is 1.0mm. The second door pit 3 is provided with a high and large space, and the low-density hot and humid air mixed with the goods when entering and leaving is squeezed upward by the high-density low-temperature gas in the cold storage, repeatedly contacts with the low-temperature color steel plate 7 in the second door pit 3 in the cold storage, cools down, and frosts, which greatly reduces the water content of the air.

[0039] The implementation principle of the double-door pit cold storage device in the embodiment of the application is that the double-door pit design adopts a "three-hole two-door" structure. In the case of less operation, the cold storage insulation door 4 can normally open and close, meeting the daily operation demand. When the cold storage insulation door 4 needs to be in the open state during the peak operation period, the quick roller shutter door 5 equipped on the outside of the first door pit 2 can effectively block the external hot and humid air from entering the cold storage interior by virtue of its quick opening and closing characteristics, thereby reducing the temperature fluctuation in the interior of the cold storage main body 1, and also significantly reducing the operating load and loss of the fan.

[0040] In addition, a larger space is arranged inside the second door pocket 3. When goods enter and exit the cold storage, the mixed low-density hot and humid air will be squeezed upwards by the high-density cold air in the cold storage. In this process, the hot and humid air will repeatedly contact the low-temperature color steel plate 7 of the door pocket in the cold storage, and the temperature will be lowered through heat exchange, and then the water vapor will frost, thereby greatly reducing the water content of the air entering the interior of the cold storage. This design principle effectively reduces the total amount of hot and humid gas entering the cold storage, thereby reducing the risk of water vapor condensation and icing of the cold storage fan, ensuring the stable operation and efficient operation of the cold storage equipment.

[0041] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, so: any equivalent changes made on the basis of the structure, shape, principle of the present application should be covered within the protection scope of the present application.
