Description

Technical Field

[0001] The utility model relates to the technical field of cold storage, in particular to a zero-wind consumption cold storage air conditioner and a cold storage system provided with the zero-wind consumption cold storage air conditioner. Background Art

[0002] Cold storage systems are mainly used to store items with specific temperature and humidity requirements. Compared with traditional refrigerators, cold storage systems have greater cooling capacity and storage space, and are widely used in food, chemical, medical, scientific experiments and other fields. There are two main types of existing cold storage systems:

[0003] The first one, such as Figure 1 As shown, a cold discharge pipe 91 is arranged in the warehouse, and heat is exchanged between the cold discharge pipe 91 and the air in the warehouse to realize refrigeration of the warehouse; this refrigeration method can reduce the air flow in the warehouse, which is more friendly to the storage of food, flowers and other items, is conducive to the preservation of items and reduces the moisture loss rate of items, thereby reducing warehouse losses. However, after this type of cold storage system has been used for a period of time, a large amount of frost will appear on the cold discharge pipe 91, thereby affecting the refrigeration efficiency of the cold storage; and it is difficult to defrost the cold discharge pipe 91, and usually the entire cold storage system needs to be powered off to allow the cold discharge pipe 91 to defrost at natural temperature or to be defrosted by pouring hot water on the cold discharge pipe 91.

[0004] The second type, such as Figure 2 As shown, a cold storage machine 92 is arranged in the warehouse 90, and the cold storage machine 92 includes a chassis 921, a heat exchanger and a fan 922. The chassis 921 is provided with an air outlet 9211, the heat exchanger is arranged in the chassis 921, and the fan 922 is installed in the air outlet 9211. The fan 922 is used to blow air into the warehouse 90 to blow the cold air formed by the heat exchange of the heat exchanger into the warehouse 90. This type of cold storage system better solves the problem of frosting and defrosting of the cold row pipe cold storage system, and makes the temperature difference between each area in the warehouse 90 smaller, and has a more stable refrigeration efficiency; however, during the refrigeration process of the cold storage system, the fan 922 blows air directly into the warehouse 90 continuously, which increases the air flow rate in the warehouse 90, so that the moisture loss rate of the items [especially food (such as fruits and vegetables), flowers, etc.] is fast, which is not conducive to the preservation of the items, resulting in a high warehouse loss rate.

[0005] It can be seen that it is difficult for the existing cold storage system to take into account refrigeration efficiency, defrosting, and preservation of goods, etc., and there are still some shortcomings. Summary of the invention

[0006] The main purpose of the utility model is to provide a zero-wind consumption cold storage air conditioner which can take into account refrigeration efficiency, defrosting and article freshness and moisture preservation at the same time.

[0007] Another object of the utility model is to provide a cold storage equipped with the above-mentioned zero wind consumption cold storage air conditioner.

[0008] In order to achieve the main purpose of the utility model, the utility model provides a zero wind consumption cold storage air conditioner, including a cold storage internal unit, the cold storage internal unit includes a chassis, a heat exchanger and a fan, the chassis has an air outlet, the heat exchanger is installed in the chassis, the fan is connected to the chassis, and the fan is located in the air outlet, wherein the zero wind consumption cold storage air conditioner also includes an air duct, the chassis is provided with a first connecting flange in the circumferential direction of the air outlet, the first end of the air duct is connected to the first connecting flange, the second end of the air duct is closed, and a plurality of air holes are arranged on the air duct, and the air holes are connected to the air outlet.

[0009] As can be seen from the above, by setting an air duct at the air outlet and arranging multiple air holes on the air duct, the cold air discharged by the fan first enters the air duct, and then spreads to the warehouse through the air holes on the air duct, thereby preventing the cold air dispersed through the air holes from stirring the air flow in the warehouse, and avoiding the items in the warehouse from being directly blown by the cold air, slowing down the rate of moisture loss of the items, playing a role in preserving and moisturizing the items, and reducing warehouse losses; at the same time, the cold air is evenly distributed to various areas in the warehouse under the action of the air holes on the air duct, reducing the temperature difference between various areas in the warehouse; in addition, since the zero wind consumption cold storage air conditioner uses the cold storage internal unit for refrigeration operation, it also effectively solves the problems of large frost and difficulty in defrosting when using traditional cold exhaust pipes.

[0010] A preferred solution is that a second connecting flange is provided at the first end of the air duct, and the first connecting flange is detachably connected to the second connecting flange.

[0011] As can be seen from the above, providing the second connecting flange at the first end of the air duct can make the connection between the air duct and the first connecting flange more reliable, and is more convenient for disassembly, replacement of the air duct and inspection and maintenance of the zero-wind consumption cold storage air conditioner.

[0012] A further solution is that the zero-wind consumption cold storage air conditioner also includes a first sealing ring, and the first sealing ring abuts between the first connecting flange and the second connecting flange.

[0013] It can be seen from the above that the first sealing ring can increase the airtightness of the connection between the first connecting flange and the second connecting flange.

[0014] Another preferred solution is that the zero wind consumption cold storage air conditioner also includes a fixed frame, the first connecting flange is frame-mounted, the first end of the air duct is sleeved on the outer circumference of the first connecting flange, the fixed frame is wrapped around the first end of the air duct, and the fixed frame clamps the first end of the air duct on the first connecting flange.

[0015] As can be seen from the above, the above design can simplify the structure of the air duct and reduce the use cost of the air duct.

[0016] Another preferred solution is that the first connecting flange is annular, and an external thread structure is provided on the outer periphery of the first connecting flange; a fixing ring is provided on the first end of the air duct, and an internal thread structure is provided on the inner wall of the fixing ring, and the internal thread structure and the external thread structure are threadedly connected.

[0017] It can be seen from the above that the above design can ensure both the reliability and convenience of the connection between the air duct and the first connecting flange, and the air tightness of the connection between the air duct and the first connecting flange.

[0018] A further solution is that the diameter of the air holes is between 5 mm and 50 mm; the length of the air duct is between 1.5 m and 50 m; the air supply direction of the air holes is arranged horizontally, or the air supply direction of the air holes is inclined to the horizontal and upward arrangement.

[0019] As can be seen from the above, through the design of the air hole diameter, the length of the air duct, etc., it is effectively ensured that the cold air generated by the machine in the cold storage can be reliably distributed to various areas in the warehouse through the air holes of the air duct, so that the temperature of each area in the warehouse meets the use requirements, and the stability and reliability of the cold storage system equipped with the zero wind consumption cold storage air conditioner are ensured; at the same time, combined with the air supply direction design of the air hole, the cold air sent into the warehouse through the air hole will not stir the airflow in the warehouse, so as to slow down the water loss rate of the goods, extend the freshness and moisture retention period of the goods, and thus reduce warehouse losses.

[0020] A further solution is that the air duct extends in a straight line, or the air duct has corners, and the number of the corners is less than or equal to three; the cross-sectional profile of the air duct is circular or rectangular.

[0021] As can be seen from the above, the air duct can be laid out in a straight line or a curved shape according to the warehouse structure; when the air duct is laid out in a curved shape, the number of bending corners of the air duct is designed so that the cold air discharged by the fan can be reliably distributed into the warehouse through the air vents.

[0022] A further solution is that the fan blades have a serrated structure, and the serrated structure is located at the trailing edge of the fan blades; the number of air outlets is less than or equal to eight, each air outlet is provided with a fan, and each air outlet is connected to an air duct.

[0023] As can be seen from the above, setting a serrated structure at the trailing edge of the fan blade is beneficial to reducing the noise and vibration generated during the operation of the cold storage unit and improving the efficiency of the fan. At the same time, the serrated structure can optimize the air outlet streamline shape of the fan, so that the cold air discharged by the fan can better enter the air duct and be evenly distributed to the warehouse through the air holes on the air duct; according to the size of the warehouse, the number of air outlets of the cold storage unit can be adjusted to ensure that the cold storage unit can meet the refrigeration needs of the warehouse.

[0024] In order to achieve another purpose of the utility model, the utility model provides a cold storage system, including a warehouse and a control device, wherein the cold storage system also includes the above-mentioned zero wind consumption cold storage air conditioner, the cold storage internal unit and the air duct are installed in the warehouse and located at the top of the warehouse, and the control device is electrically connected to the zero wind consumption cold storage air conditioner.

[0025] It can be seen from the above that the cold storage system equipped with the above-mentioned zero wind consumption cold storage air conditioner can ensure the refrigeration efficiency in the warehouse; at the same time, the machine in the cold storage has automation capabilities to avoid excessive frost in the warehouse; furthermore, with the cooperation of the air duct, it can effectively prevent the cold air discharged by the machine in the cold storage from stirring the air flow in the warehouse and directly blowing on the objects, slowing down the rate of moisture loss of the objects, keeping the objects fresh and moisturizing, and reducing warehouse losses.

[0026] A further solution is that the cold storage system also includes a temperature sensor and a humidity sensor. The temperature sensor is arranged in the warehouse and is electrically connected to the control device. The humidity sensor is arranged in the warehouse and is electrically connected to the control device.

[0027] As can be seen from the above, the temperature sensor and humidity sensor are used to monitor the temperature and humidity conditions in the warehouse in real time, and provide real-time feedback to the control device, so that the control device can control the zero-wind consumption cold storage air conditioner to make corresponding work adjustments according to the real-time temperature and humidity in the warehouse, thereby ensuring a constant temperature and humidity storage environment in the warehouse.

[0034] The first embodiment of zero wind consumption cold storage air conditioner

[0035] Reference Figure 3The zero wind consumption cold storage air conditioner 100 includes a cold storage indoor unit 1, a cold storage outdoor unit and an air duct 2; wherein the cold storage indoor unit 1 is arranged in the warehouse of the cold storage system to control and adjust the temperature and humidity of the warehouse so that the warehouse is in a constant temperature and humidity state; the cold storage outdoor unit is arranged outside the warehouse and is connected to the cold storage indoor unit 1 through a pipeline, and provides a low-temperature and low-pressure liquid refrigerant to the cold storage indoor unit 1, so that the cold storage indoor unit 1 cools the warehouse.

[0036] The cold storage internal machine 1 includes a chassis 11, a heat exchanger and a fan 12. The chassis 11 has an air outlet 111, and the air outlet 111 is connected to the inside of the chassis 11. The number of air outlets 111 is selected according to the size of the storehouse to ensure the reliability and stability of the cold storage internal machine 1 in cooling the storehouse. Preferably, the number of air outlets 111 is less than or equal to eight. For example, in this embodiment, the chassis 11 has two air outlets 111.

[0037] The heat exchanger is installed in the chassis 11, and the size of the heat exchanger matches the number of the air outlets 111, so that in the axial direction of the air outlets 111, the projection of each air outlet 111 overlaps with the projection of the heat exchanger at least partially. The heat exchanger is used to receive the low-temperature and low-pressure liquid refrigerant delivered by the cold storage external machine, and to exchange heat between the low-temperature and low-pressure liquid refrigerant and the air in the warehouse, so that the air in the warehouse forms cold air and is discharged into the warehouse by the fan 12.

[0038] The fan 12 is connected to the chassis 11, and the fan 12 is located in the air outlet 111. The number of the fans 12 is equal to the number of the air outlets 111, that is, each air outlet 111 is provided with a fan 12, and the fan 12 is used to discharge the cold air formed after the heat exchange in the chassis 11 out of the chassis 11, and finally discharge the cold air into the cold storage to cool and reduce the temperature of the cold storage.

[0039] The air duct 2 is connected to the air outlet 111, so that the cold air discharged by the fan 12 directly enters the air duct 2, and then is evenly distributed to various areas in the warehouse through the air duct 2, so as to avoid the cold air discharged by the fan 12 directly entering the warehouse to stir the air flow in the warehouse, so that the items in the warehouse are not directly blown by the cold air, thereby effectively slowing down the speed of moisture loss of the items, keeping the items fresh and moisturizing, and reducing warehouse losses. Among them, the number of air ducts 2 is equal to the number of air outlets 111, that is, each air outlet 111 is connected to an air duct 2.

[0040] The chassis 11 is provided with a first connecting flange 112 on the circumference of each air outlet 111; the first end of the air duct 2 is connected to the first connecting flange 112, and the second end of the air duct 2 is closed. In addition, a plurality of air holes 22 are arranged on the air duct 2, and the air holes 22 are connected to the air outlet 111. For example, in the present embodiment, the first connecting flange 112 is provided with a first connecting hole 1121, the first end of the air duct 2 is provided with a second connecting flange 21, and the second connecting flange 21 is provided with a first through hole 211. When the air duct 2 is connected to the air outlet 111, the first fastener 3 (such as a bolt) passes through the first through hole 211 on the second connecting flange 21 and is connected to the first connecting hole 1121 on the first connecting flange 112, thereby fixing the first connecting flange 112 and the second connecting flange 21. By providing a second connecting flange 21 at the second end of the air duct 2 and detachably connecting the second connecting flange 21, the disassembly and assembly of the air duct 2 and the replacement and inspection and maintenance of the zero-wind consumption cold storage air conditioner 100 are more convenient, and the first connecting flange 112 and the second connecting flange 21 can ensure the reliability and firmness of the connection between the air duct 2 and the air outlet 111.

[0041] Preferably, the zero-wind consumption cold storage air conditioner 100 also includes a first sealing ring, which abuts between the first connecting flange 112 and the second connecting flange 21 to seal the gap between the first connecting flange 112 and the second connecting flange 21, thereby ensuring the airtightness of the docking of the first connecting flange 112 and the second connecting flange 21.

[0042] Furthermore, a sawtooth structure 1211 is provided on the blade 121 of the fan 12, and the sawtooth structure 1211 is located at the rear edge of the blade 121. The setting of the sawtooth structure 1211 is conducive to reducing the noise and vibration generated during the operation of the cold storage machine 1 and improving the efficiency of the fan 12; at the same time, the sawtooth structure 1211 can optimize the air outlet streamline shape of the fan 12, so that the cold air discharged by the fan 12 can better enter the air duct 2 and be evenly distributed into the warehouse through the air vents 22 on the air duct 2.

[0043] In addition, the aperture of the air holes 22 on the air duct 2 is preferably between 5 mm and 50 mm, and the length of the air duct 2 is preferably between 1.5 meters and 50 meters, so that the cold air generated by the machine 1 in the cold storage can be reliably distributed to various areas in the warehouse through the air holes 22 of the air duct 2, so that the temperature of each area in the warehouse meets the use requirements and the temperature difference is small, thereby improving the stability and reliability of the operation of the zero wind consumption cold storage air conditioner 100.

[0044] Furthermore, the air supply direction of the air holes 22 is preferably arranged horizontally, or the air supply direction of the air holes 22 is preferably arranged upwardly inclined to the horizontal. This design ensures that the cold air sent into the warehouse through the air holes 22 will not stir the airflow in the warehouse, thereby slowing down the rate of moisture loss of the items, extending the freshness and moisture retention period of the items, and thus reducing warehouse losses.

[0045] In addition, in the actual application of the zero wind consumption cold storage air conditioner 100, the layout of the air duct 2 can be designed according to the size and structure of the warehouse; for example, the air duct 2 can be designed to extend in a straight line; for another example, the air duct 2 can be set to a bent shape with corners, wherein the number of corners is preferably less than or equal to three, so that the cold air discharged by the fan 12 can be reliably distributed into the warehouse through the air vents 22. In addition, the cross-sectional profile of the air duct 2 can also be set to a circle or a rectangle according to needs. For example, in this embodiment, the cross-sectional profile of the air outlet 111 and the cross-sectional profile of the air duct 2 are both circular; of course, in other embodiments, the cross-sectional profile of the air outlet 111 and the cross-sectional profile of the air duct 2 can also be set to a rectangle. Furthermore, the air duct 2 can be a flexible air duct 2 or a rigid air duct 2 as needed.

[0046] In summary, it can be seen that through the design of the zero wind consumption cold storage air conditioner 100, the cold air generated by the cold storage internal unit 1 first enters the air duct 2 through the action of the fan 12, and then is distributed to the warehouse through the air holes 22 on the air duct 2, thereby preventing the cold air dispersed through the air holes 22 from stirring the air flow in the warehouse, and at the same time avoiding the items in the warehouse from being directly blown by the cold air, effectively slowing down the rate of moisture loss of the items, improving the freshness and moisturizing effect of the items, and reducing warehouse losses; at the same time, under the guidance of the air holes 22 on the air duct 2, the cold air can be more evenly distributed to various areas in the warehouse, thereby reducing the temperature difference between various areas in the warehouse; furthermore, since the zero wind consumption cold storage air conditioner 100 adopts the cold storage internal unit 1 for refrigeration operations, it effectively solves the problems of large frost and difficulty in defrosting that exist in traditional operations using cold exhaust pipes.

[0047] Second embodiment of zero wind consumption cold storage air conditioner

When the fixing frame 41 is connected to the first connecting flange 42, a second fastener 44 (such as a bolt, a rivet, etc.) passes through the second through hole 411 on the fixing frame 41 and the air duct 43 and is fixedly connected to the second connecting hole 421 on the first connecting flange 42, so that the fixing frame 41 clamps and fixes the first end of the air duct 43 on the first connecting flange 42. In the axial direction of the air outlet 45, the cross-sectional profile of the fixing frame 41 and the cross-sectional profile of the first connecting flange 42 can be both circular or rectangular. The above design can simplify the structure of the air duct 43 and reduce the use cost of the air duct 43.

[0050] The third embodiment of the zero wind consumption cold storage air conditioner

[0051] Reference Figure 5 The difference between this embodiment and the first embodiment of the zero wind consumption cold storage air conditioner lies in the connection structure between the air duct and the air outlet. Specifically, in this embodiment:

When the air duct 52 is connected to the first connection flange 51, the air duct 52 is threadedly connected through the internal thread structure 5211 on the fixing ring 521 and the external thread structure 511 on the first connection flange 51. This design can ensure the reliability and convenience of the connection between the air duct 52 and the first connection flange 51, and can also ensure the airtightness of the connection between the air duct 52 and the first connection flange 51.
