Description

Technical Field

[0001] The utility model relates to the technical field of cold storage, in particular to a defrosting system for a cold storage. Background Art

[0002] Cold storages are widely used in industries, commerce and agriculture, covering industries such as medicine, food, semiconductors, beauty, etc. Currently, all cold storages are classified according to the storage temperature, mainly including: high-temperature cold storage (5 - 15°C), medium-temperature cold storage (-5 - 5°C), low-temperature cold storage (-18 - -25°C), quick-freezing cold storage (-35 - -40°C), deep cold storage (-45 - -60°C), and low-temperature cold storage occupies the main market. With the rapid expansion of cold storage logistics and market competition in recent years, how to keep the cold storage efficient and intelligent, and achieve labor saving and energy consumption reduction in operation has become an urgent problem in the industry.

[0003] Since the temperature inside the cold storage is very low, and the stored goods and the frequent opening of the door during incoming and outgoing goods will inevitably cause the transfer of external moisture into the warehouse, resulting in frosting inside the cold storage. The frosting locations include the surface of goods, the ground, the top of the cold storage, the positions near the door, etc. Although these frosting locations will not cause an increase in energy consumption, they may involve safety problems, such as slipping on the ground. In addition to frosting in the above locations, the most important frosting pain point for cold storages is that, for example, in cold storages using cold air refrigeration, frost will form on the heat exchanger fins, which will cause frost blockage over time. At the same time, frosting on the fin surface will lead to a decrease in heat transfer efficiency and an increase in refrigeration energy consumption. For cold storages using aluminum pipe coils for refrigeration, frosting on the pipes will also cause the same problems. Therefore, the cold storage must be defrosted regularly to ensure normal operation. Currently, the common defrosting methods and problem points are as follows:

[0004] (1) Electric defrosting. The problem is that the power consumption is very high, and after defrosting, drainage is required. The water that cannot be drained completely will still freeze inside the warehouse or on the fins, and the effect is not thorough;

[0005] (2) Hot fluorine defrosting. This method has a long defrosting time and is not thorough. At the same time, too many defrosting times or frequent defrosting may cause failures in the refrigeration system, and the risk is relatively high. Content of the Utility Model

[0050] Now, the exemplary embodiments will be described more comprehensively with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; on the contrary, these embodiments are provided to make the present utility model more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. Identical reference numerals in the figures denote identical or similar structures, and thus repeated descriptions thereof will be omitted.

[0051] The words expressing positions and directions described in the present utility model are illustrative with reference to the accompanying drawings, but can be changed as needed, and all changes made are included within the protection scope of the present utility model.

[0052] Refer to Figures 1 to 9 , this application provides a cold storage defrosting system, including: a cold storage body 1 and a dehumidifying device.

[0053] Specifically, the dehumidification device has a dehumidification rotor 201, which has a treatment area and a regeneration area. The dehumidification device reduces the internal moisture of the cold storage body 1 and removes the internal frost of the cold storage body 1 through the dehumidification rotor 201. Among them, the dehumidification device has a treatment air inlet 202 and a treatment air outlet 203. The treatment air inlet 202 can extract the gas to be treated from the inside of the cold storage body 1, and the gas to be treated is the high-humidity air inside the cold storage body 1. The treatment air outlet 203 can re-transport the dry gas after being adsorbed and dehumidified by the dehumidification rotor 201 back to the cold storage body 1. As a preferred method, the cold storage body 1 has an exhaust pipe 101 and an intake pipe 102. The exhaust pipe 101 is used to connect to the treatment air inlet 202, and the intake pipe 102 is used to connect to the treatment air outlet 203. Among them, the intake pipe 102 is arranged away from the exhaust pipe 101, which can enhance the circulation effect of the internal air flow of the cold storage body 1 and improve the dehumidification and defrosting efficiency of the cold storage. In practical applications, the intake pipe 102 includes an exposed section 1021 located outside the cold storage body 1 and an internal section 1022 located inside the cold storage body 1. The exposed section 1021 is communicated with the internal section 1022. Among them, the internal section 1022 is located at the top inside the cold storage body 1, and the exhaust pipe 101 is located at the bottom inside the cold storage body 1. Generally, inside the cold storage body 1, dry air is at the bottom and wet air is at the top. Visually, the upper part inside the cold storage generally shows a "white and hazy" state. When the dehumidification device operates, the wet air in the upper part of the cold storage is discharged through the exhaust pipe 101, and the dry air after being adsorbed and dehumidified enters the cold storage through the intake pipe 102.

[0054] It should be noted that the dehumidification device can be installed inside the cold storage body 1 or outside the cold storage body 1. The actual installation position of the dehumidification device can be selected according to the actual situation. When the dehumidification device is installed outside the cold storage body 1, not only strict thermal insulation measures need to be taken for the inside and outside of the dehumidification device to prevent the formation of cold bridges, but also strict thermal insulation measures need to be taken for the exhaust pipe 101 and the intake pipe 102 to reduce the temperature rise during the cold storage dehumidification process.

[0055] Therefore, the defrosting system of this cold storage uses a dehumidification device with a dehumidification wheel 201 as the core to dehumidify and defrost the cold storage. The dehumidification wheel 201 has more advantages at low temperatures. Using its own adsorption and desorption principle, it can dry the humid air in the storage and discharge it outside the storage. No condensate is generated during the entire dehumidification process of the cold storage, and there is no need to drain water in the cold storage. This solves the problem of inconvenient drainage of cold water generated by using defrosting methods such as electric defrosting and hot fluorine defrosting. The remaining cold water in the cold storage cannot be drained completely and will re-condense, resulting in incomplete dehumidification and defrosting effects in the cold storage. At the same time, there is no obvious temperature fluctuation in the cold storage during the operation of the defrosting system of this cold storage. However, regardless of using defrosting methods such as electric defrosting and hot fluorine defrosting, the refrigeration system of the cold storage needs to be turned off to increase the temperature of the storage, which affects the use of the cold storage and increases the energy consumption of the cold storage. By adopting a more novel and energy-saving defrosting method, the humidity problem in the cold storage is fundamentally solved, the possibility of frosting in the storage is reduced, and the cumbersome operation of defrosting and draining in the future is eliminated.

[0056] In a specific embodiment, referring to Figure 1 , the cold storage body 1 is provided with a refrigeration device 103. The refrigeration device 103 is arranged on one side of the cold storage body 1 away from the exhaust pipe 101. A plurality of exhaust ports 1023 facing the refrigeration device 103 are opened on the surface of the built-in section 1022 to remove the frost in the refrigeration device 103. Among them, the refrigeration device 103 can be a device using a cold air conditioner for refrigeration. For a cold storage using a cold air conditioner for refrigeration, the dry air after being adsorbed and dehumidified by the dehumidification device is blown towards the cold air conditioner through the exhaust ports 1023 on the built-in section 1022, and the frost on its heat exchange fins can be removed; the refrigeration device 103 can also be a device using an aluminum row pipe for refrigeration. For a cold storage using an aluminum row pipe, the dry air after being adsorbed and dehumidified by the dehumidification device is blown towards the aluminum row pipe through the exhaust ports 1023 on the built-in section 1022, and the frost on the aluminum row pipe can be removed.

[0057] As a preferred method, referring to Figure 1 、 Figure 2 and Figure 3 , the dehumidification device is a dehumidifier 2 with a dehumidification wheel 201 inside. The dehumidifier 2 has a regeneration air inlet 204 and a regeneration air outlet 205. The regeneration air inlet 204 is used to transport the regeneration gas to the air inlet side of the regeneration area of the dehumidification wheel 201 to desorb and regenerate the regeneration area of the dehumidification wheel 201. The regeneration air outlet 205 is used to discharge the regeneration gas discharged from the air outlet side of the regeneration area of the dehumidification wheel 201 from the dehumidifier 2; it should be noted that the regeneration gas used to desorb and regenerate the regeneration area of the dehumidification wheel 201 can be the warmed outside ambient air.

[0058] In actual tests, when using the dehumidifier 2 to defrost the cold storage, under the conditions that the temperature of the cold storage body 1 is -18°C, the humidity is 90% RH, and the moisture content is 0.82 g / kg, start the dehumidifier 2 to make it work for one hour. After one hour, the humidity in the cold storage can be reduced to 42.6% RH, and the moisture content is 0.39 g / kg. Thus, by reducing the water content in the cold storage, the phenomenon of ice formation in the cold storage can be avoided. Moreover, the relatively dry air after dehumidification blows against the frosted refrigeration device 103, such as a cooling fan or an aluminum fin tube, and the frost can be gradually removed. Among them, RH is the relative humidity, that is, it represents the ratio of the absolute humidity in the air to the saturated absolute humidity at the same temperature and air pressure.

[0059] The processing air inlet 202 is used to convey the gas to be processed to the air inlet side of the processing area of the dehumidification wheel 201 to adsorb and dehumidify the gas to be processed. The processing air outlet 203 is used to discharge the dry gas discharged from the air outlet side of the processing area of the dehumidification wheel 201 from the dehumidifier 2. It should be noted that when the dehumidifier 2 dehumidifies the gas to be processed in the cold storage, there will be a certain temperature rise, but in the application of the cold storage, the temperature rise is very small, about 4 - 5°C or so. However, since the moisture content of the dry air after adsorption dehumidification is low and the enthalpy value is also low, the heat load brought to the operation of the refrigeration system of the cold storage is very small, and the energy consumption increased by the temperature rise of the dry gas in actual application can be almost ignored.

[0060] The cold storage defrosting system further includes a heat exchange component 3 for increasing the temperature of the regeneration gas. The heat exchange component 3 is externally connected to a heat source, and the temperature of the regeneration gas rises after passing through the heat exchange component 3. In a specific application, the heat exchange component 3 is preferably a heat exchanger, and the heat source preferably comes from the heat generated at the condensation end of the refrigeration device 103. The heat generated at the condensation end of the refrigeration device 103 passes through the inside of the heat exchanger and makes the surface of the heat exchanger warm up. Since the regeneration area of the dehumidification wheel 201 has a low requirement for the regeneration temperature, the heat generated at the condensation end of the refrigeration device 103 of the cold storage refrigeration system can be recycled to heat the regeneration gas. The dehumidifier 2 can dehumidify and defrost the cold storage, and the waste heat of the refrigeration system of the cold storage body 1 can heat the regeneration gas of the dehumidifier 2, enabling the dehumidifier 2 and the cold storage body 1 to cooperate with each other and improving the energy-saving effect. It should be noted that the heat exchange component 3 can not only use the heat generated at the condensation end of the refrigeration device 103 to increase the temperature of the regeneration gas, but also use electric heating, the condensation heat of other equipment, waste hot water or other waste heat sources on site as the heat source for increasing the temperature of the heat exchange component 3.

[0061] In a specific embodiment, refer to Figure 4 、 Figure 5 、 Figure 8 and Figure 9, the dehumidifier 2 further includes a processing air inlet member, which is used to be arranged on the air inlet side of the processing area of the dehumidification rotor 201 and the air outlet side of the regeneration area. The processing air inlet member includes a first channel 401 and a second channel 402. It should be noted that the chamber wall of the first channel 401 needs to be strictly insulated to prevent the gas to be processed inside the first channel 401 from exchanging heat with the objects outside the channel, and to reduce the temperature rise during the adsorption dehumidification process of the gas to be processed.

[0062] Among them, the overall structure of the processing air inlet member is a special-shaped structure. At the same time, the first channel 401 is also designed as a special-shaped structure. A through hole penetrating both sides is provided in the middle of the processing air inlet member for the support shaft of the dehumidification rotor 201 to pass through. Along the flow direction of the gas to be processed, the radial cross-section of the first channel 401 gradually increases. The first channel 401 is used to be arranged on the air inlet side of the processing area of the dehumidification rotor 201 and supply the gas to be processed to flow through the entire processing area of the dehumidification rotor 201. Specifically, the structure of the first channel 401 is not a regular hollow frustum structure, but the small-area top surface of the hollow frustum-like structure inclines towards one side of the central axis. The chamber wall of the first channel 401 is preferably set in a way of variable diameter with special shape. More specifically, the first channel 401 formed by variable diameter with special shape can make the radial cross-section inside the channel gradually increase, and the inside of the chamber wall of the first channel 401 has a natural transition and no dead corner area, so that the flow field of the gas to be processed entering the channel can be made more uniform, the entire surface area of the processing area of the dehumidification rotor 201 can be effectively utilized, the airflow accumulation can be avoided from concentrating on the surface of some processing areas, and the dehumidification efficiency of the dehumidification rotor 201 can be improved.

[0063] The second channel 402 is isolated from the first channel 401. The second channel 402 is used to be arranged on the air outlet side of the regeneration area of the dehumidification rotor 201 and discharge the regeneration gas.

[0064] As an example:

[0065] The end faces of the first channel 401 and the second channel 402 cooperating with the dehumidification rotor 201 form a circular covering surface. The other end face of the first channel 401 is set as a circular interface for connecting external pipelines, etc. The above circular covering surface can cover the end face of the dehumidification rotor 201. For example, the area of the processing area of the dehumidification rotor 201 is three-quarters of the end face, and the area of the regeneration area is one-quarter of the end face, thus forming the complete end face of the dehumidification rotor 201. Adaptively, the first channel 401 is set as a circular covering surface corresponding to three-quarters of the processing area, and the second channel 402 is set as a circular covering surface corresponding to one-quarter of the regeneration area.

[0066] It should be noted that in the first channel 401 with a circular interface at one end and a three-quarter area end face at the other end, a variable diameter with a non-uniform shape is adopted to gradually increase the radial cross-section of the first channel 401, so as to make the flow field of the gas to be processed entering the channel more uniform, effectively utilize the entire surface area of the processing area of the dehumidifying rotor 201, avoid the accumulation of air flow concentrated on the surface of part of the processing area, and improve the dehumidification efficiency of the dehumidifying rotor 201.

[0067] Therefore, the processing air inlet part is integrally formed with a plastic structure with high strength and good heat resistance. The cavity wall of the first channel 401 of the processing air inlet part adopts a special structure with variable diameter, so that its radial cross-section gradually increases, making the flow field discharged through the air duct of the first channel 401 more uniform, promoting the air flow to reach the entire processing area of the dehumidifying rotor 201, making the entire rotor surface of the processing area an effective utilization area, eliminating the dead corner area of the processing area, improving the dehumidification efficiency of the dehumidifying rotor 201, and further improving the dehumidification effect of the dehumidifier 2 on the high-humidity gas to be processed in the cold storage, effectively avoiding frosting inside the cold storage.

[0068] In a specific embodiment, referring to Figure 6 、 Figure 7 、 Figure 8 and Figure 9 , the dehumidifier 2 further includes a chassis 6 and a processing air outlet part.

[0069] Among them, the chassis 6 is used to install the dehumidifying rotor 201. It should be noted that the chassis 6 needs to be strictly insulated inside and outside to prevent the cold bridge from forming at the dehumidifier 2 in the cold storage defrosting system.

[0070] The processing air outlet part is arranged on the air outlet side of the processing area of the dehumidifying rotor 201 and the air inlet side of the regeneration area. The processing air outlet part includes a third channel 501 and a side port 502; the third channel 501 is used to be arranged at the air outlet side of the processing area of the dehumidifying rotor 201 and discharge the gas to be processed after adsorption dehumidification, and the side port 502 is isolated from the third channel 501. The side port 502 is used to be arranged at the air inlet side of the regeneration area of the dehumidifying rotor 201. It should be noted that the cavity wall of the third channel 501 needs to be strictly insulated to avoid heat exchange between the dry gas inside the third channel 501 and the objects outside the channel, reducing the temperature rise of the dry gas.

[0071] In this embodiment, referring to Figure 8 and Figure 9, the dehumidifier 2 further includes at least two support members 601 detachably arranged inside the chassis 6, and the dehumidification rotor 201 is rotatably arranged between two adjacent support members 601. It should be noted that an annular track or guide rail for the dehumidification rotor 201 to rotate is arranged between the opposite surfaces of two adjacent support members 601. The support member 601 is preferably in a plate-like structure, and the inner side of the annular track of the support member 601 in the plate-like structure is a through-opening structure, so that the treatment area and the regeneration area of the dehumidification rotor 201 can smoothly pass through the corresponding regeneration gas or gas to be treated.

[0072] A driving component 602, a transmission belt, a tensioner 603 and a limit switch 604 are installed on the support member 601. The transmission belt is arranged on the dehumidification rotor 201. The driving component 602 is in transmission connection with the transmission belt and is used to drive the dehumidification rotor 201 to rotate. The tensioner 603 is used to tension the transmission belt, and the limit switch 604 is used to be triggered when the dehumidification rotor 201 rotates to judge whether the dehumidification rotor 201 rotates. It should be noted that the driving component 602 is preferably a transmission motor, and a pulley for connecting the transmission belt is installed at the output end of the transmission motor. The transmission belt is wound around the dehumidification rotor 201, the tensioner 603, the pulley and the limit switch 604. When the transmission motor works, the dehumidification rotor 201 can be driven to rotate through the transmission belt. Among them, when the dehumidification rotor 201 rotates one circle, the limit switch 604 is triggered once. There is a time setting in the program setting of the dehumidifier system. If the limit switch 604 does not trigger the program beyond the time setting range, it will be judged that the dehumidification rotor 201 has a rotation failure or does not rotate, so as to realize the monitoring of the working process of the dehumidification rotor 201.

[0073] In a specific implementation manner, referring to Figure 3 , Figure 8 and Figure 9 , the dehumidifier 2 further includes a treatment air duct assembly and a regeneration air duct assembly.

[0074] The treatment air duct assembly includes a treatment fan 701.
