Description
Technical Field
[0001] This application relates to the field of cold storage, and more particularly to a household cold storage. Background Technology
[0002] A refrigerator is a refrigeration device that maintains a constant low temperature. It is a household appliance used to keep food or other items at a constant low temperature. The refrigerator contains a compressor, an ice maker, a cabinet or box for freezing ice, and a storage compartment with a refrigeration unit. The capacity of a household refrigerator typically ranges from 20 to 500 liters. Refrigerators usually use Freon (a halocarbon refrigerant). Freon has a strong permeability and is prone to leakage, which is difficult to detect. When leaked Freon molecules come into contact with an open flame, or when they rise into the stratosphere, under strong solar radiation or at temperatures above 400°C, they decompose into toxic hydrogen fluoride and hydrogen chloride, releasing toxic phosgene, which causes significant damage to the ozone layer.
[0003] With changing lifestyles, especially for special circumstances, refrigerators designed for home use may be either insufficient in capacity or take up too much space. Cold storage, on the other hand, is a low-temperature freezing device, typically operating at temperatures between -10°C and -30°C. It stores a large quantity of frozen food and has a much larger refrigeration area than a refrigerator. While sharing the same refrigeration principle as refrigerators, cold storage, due to its larger footprint, is unsuitable for ordinary households.
[0004] Regarding the aforementioned technologies, the inventors believe that refrigerators may have limited storage space, while cold storage facilities are not suitable for household use and have the drawback of not being able to accommodate different storage needs. Summary of the Invention
[0005] To meet different storage needs in daily life, this application provides a household cold storage.
[0006] This application provides a household cold storage facility, which adopts the following technical solution: A household cold storage unit includes: The storage unit includes an ice-temperature storage room and a freezer storage room, both of which include multiple storage spaces; The transfer unit includes a transfer assembly and a transfer track for moving the rotating assembly. The transfer assembly includes an ice-temperature transfer component and a freezing transfer component. The ice-temperature transfer component is disposed on one side of the ice-temperature storage room, and the freezing transfer component is disposed on one side of the freezing storage room.
[0007] A refrigeration system for providing refrigeration energy to the storage unit includes a compressor, a flash converter, and piping connecting the compressor, the flash converter, and the storage unit. Insulation material is provided between the storage section and the main building.
[0008] By adopting the above technical solution, the refrigeration system provides energy to the storage unit. The refrigeration system contains a refrigerant that needs to be converted. The compressor and flash heat exchanger are used to switch the state of the refrigerant to refrigerate the ice-temperature storage and the freezer. Both the ice-temperature storage and the freezer have multiple storage spaces. Users can occupy one or more storage spaces according to their own needs. This can meet the needs of families who do not have a refrigerator but occasionally need to freeze or refrigerate some items, as well as families who have a refrigerator but whose refrigerator storage space is insufficient and need to use a large amount of storage space. Due to the large number of storage spaces, the ice-temperature storage and the freezer are relatively large. The transfer unit is used to take items from the ice-temperature storage and the freezer to different places, or to transfer items from different places to the ice-temperature storage or the freezer. Transfer tracks are set in the ice-temperature storage, the freezer, and the places where items need to be taken out or placed. The ice-temperature transfer unit is used to transfer items that need to be refrigerated or have already been refrigerated back and forth, and the freezer is used to transfer items that need to be frozen or have already been frozen back and forth, meeting different storage needs in daily life.
[0009] Preferably, the system also includes multiple windows, each of which is located inside a room of the building body. Each room of the building body with the windows is equipped with a controller, which controls the transfer unit to transfer items from one or more storage spaces in the ice-temperature storage and / or the freezer to the window.
[0010] By adopting the above technical solution, when it is necessary to put items into the ice-temperature storage or frozen storage, the items to be stored are placed into the window. The controller controls the ice-temperature transfer component and the frozen transfer component. After being controlled by the controller, the ice-temperature transfer component or the frozen transfer component puts the items into the storage space of the ice-temperature storage or the frozen storage according to the needs. When it is necessary to take out items from the ice-temperature storage or frozen storage, the controller transfers the items in the ice-temperature storage or frozen storage to the window through the ice-temperature transfer component and the frozen transfer component, and then they are retrieved manually.
[0011] Preferably, the storage unit is located in the basement of the building body, and multiple transfer tracks are provided. The multiple transfer tracks are divided into two groups: one group of transfer tracks is for ice-temperature transfer tracks, and the other group of transfer tracks is for freezing transfer tracks. The ice-temperature transfer track connects the storage space inside the ice-temperature storage room to the window, and the freezing transfer track connects the storage space inside the freezing storage room to the window.
[0012] By adopting the above technical solution, when in use, the ice-temperature transfer unit transfers items from the ice-temperature storage to the window inside the room via the ice-temperature transfer track, and the freezing transfer unit transfers items from the freezing storage to the window inside the room via the freezing transfer track. Separating the transfer of items from the ice-temperature storage to the freezing storage can improve the efficiency of retrieval and placement, making it more convenient to use.
[0013] Preferably, both the freezer and the ice-temperature storage are multi-story, and both are located within the villa. The size of the ice-temperature storage and the freezer is determined according to the number of stories in the villa. Each story of the villa is equipped with an ice-temperature transfer unit and a freezer transfer unit.
[0014] By adopting the above technical solution, when cold storage is set up inside a villa, it is generally set up with multiple floors, and the size of the cold storage is set according to the size of the villa for easy use.
[0015] Preferably, the villa is equipped with a cold storage well, the transfer track is installed inside the cold storage well, insulation material is installed between the cold storage well and the building body, and a refrigeration structure is installed inside the cold storage well.
[0016] By adopting the above technical solutions, insulation materials can reduce the heat consumption of ice storage and cold storage, thereby achieving the goal of energy conservation and emission reduction.
[0017] Preferably, it also includes carbon dioxide, which is circulated within the compressor, the flash converter, and the pipeline.
[0018] By adopting the above technical solution, both the flash heat exchanger and the compressor are used to convert carbon dioxide. When the temperature and pressure of the carbon dioxide rise to a certain value, it becomes a high-temperature, high-pressure gaseous state. This high-temperature, high-pressure gaseous carbon dioxide provides heat to the energy-consuming components within the building that require heating. The low-temperature, low-pressure gaseous carbon dioxide is used to exchange heat with equipment within the building that requires cooling or refrigeration. Some of the carbon dioxide after heat exchange is converted from either the low-temperature, low-pressure gaseous state or the high-temperature, high-pressure gaseous state to a medium-pressure state. After conversion, it is transported back to the storage tank through pipelines and, as needed, continues to be converted to provide energy for ice storage and freezers. (Description error; system operation mode not clearly understood) Preferably, the pipeline includes a low-temperature, low-pressure pipe and a medium-temperature, medium-pressure pipe, and both the ice storage room and the freezer are connected to the low-temperature, low-pressure pipe and the medium-temperature, medium-pressure pipe.
[0019] By adopting the above technical solution, the medium-temperature and medium-pressure pipe is used to transport carbon dioxide in normal state, and the low-temperature and low-pressure pipe is used to transport low-temperature and low-pressure gaseous carbon dioxide.
[0020] Preferably, control valves are provided near both the ice storage room and the freezer on the medium-temperature and medium-pressure pipe, and the opening degree of the control valve on the medium-temperature and medium-pressure pipe connected to the ice storage room is greater than that of the control valve on the medium-temperature and medium-pressure pipe connected to the freezer.
[0021] By adopting the above technical solution, the control valve is used to control the flow rate of low-temperature and low-pressure gaseous carbon dioxide. For ice storage and cold storage, the opening degree of the control valve on the low-pressure pipe and medium-pressure pipe can be controlled according to different needs, thereby adjusting the temperature inside the ice storage and cold storage.
[0022] Preferably, the ice-temperature transfer component is an ice-temperature transfer robot, and the freezing transfer component is a freezing transfer robot. Both the ice-temperature transfer robot and the freezing transfer robot are equipped with a robotic arm or mechanical frame for picking up and placing items.
[0023] By adopting the above technical solution, when in use, items can be placed in the mechanical frame or retrieved by the robotic arm. Items placed in the mechanical frame or retrieved by the robotic arm are then transferred and moved via the Binwen transfer unit and the refrigerated transfer unit.
[0024] Preferably, each room in the building body is provided with one or more windows, and the opening directions of the windows are the same or different.
[0025] By adopting the above technical solution, the window settings can be configured according to the actual situation, and windows with openings in different directions are all for ease of use.
[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The refrigeration system provides energy to the storage unit. It contains a refrigerant that needs to be converted. A compressor and flash heat exchanger switch the state of the refrigerant to refrigerate the ice-temperature and freezer compartments. Both ice-temperature and freezer compartments have multiple storage spaces. Users can occupy one or more storage spaces according to their needs. This caters to families without refrigerators who occasionally need to freeze or refrigerate items, as well as families with refrigerators but insufficient storage space requiring a large amount of storage. Due to the large storage space, the ice-temperature and freezer compartments are relatively large. The transfer unit is used to move items from the ice-temperature and freezer compartments to different locations, or to transfer items from different locations to the ice-temperature or freezer compartments. Transfer tracks are installed in the ice-temperature and freezer compartments, as well as at the locations where items need to be retrieved or placed. The ice-temperature transfer unit is used to move items that need to be refrigerated or are already refrigerated, while the freezer unit is used to move items that need to be frozen or are already frozen, meeting various storage needs in daily life.
[0027] 2. When items need to be added to the temperature-controlled or frozen storage, the items are placed into the window. The controller then controls the temperature-controlled and frozen transfer components. After being controlled by the controller, the temperature-controlled and frozen transfer components place the items into the storage space of the temperature-controlled or frozen storage according to the requirements. When items need to be removed from the temperature-controlled or frozen storage, the controller transfers the items from the temperature-controlled or frozen storage to the window via the temperature-controlled and frozen transfer components, and then the items are retrieved manually.
[0028] 3. Both the flash heat exchanger and the compressor are used to convert carbon dioxide. When the temperature and pressure of carbon dioxide rise to a certain value, carbon dioxide becomes a high-temperature and high-pressure gaseous state. The high-temperature and high-pressure gaseous carbon dioxide provides heat to the energy-consuming components that need to be heated in the main body of the building. The low-temperature and low-pressure gaseous carbon dioxide is used to exchange heat with the equipment in the main body of the building that needs to be cooled or refrigerated. Some of the carbon dioxide after heat exchange is converted from the low-temperature and low-pressure gaseous state or the high-temperature and high-pressure gaseous state into a medium-pressure state. After conversion, it is transported back to the storage tank through pipelines and continues to be converted into a state to provide energy for ice storage and cold storage according to demand.

[0031] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0032] This application discloses a household cold storage facility. The household cold storage facility is installed inside the main building, as shown in the following embodiment. Figure 1 and Figure 2The household cold storage includes a storage unit 1, a refrigeration system 2 for providing energy to the storage unit 1, and a transfer unit 3 for transferring items within the storage unit 1. The storage unit 1 includes a temperature-controlled storage unit 11 and a freezer storage unit 12. Both the temperature-controlled storage unit 11 and the freezer storage unit 12 include multiple storage spaces 13 and multiple windows, which are respectively located inside each room of the building.
[0033] Reference Figure 1 and Figure 2 Each room in the building is equipped with a controller. The controller controls the transfer unit 3 to move items from one or more storage spaces 13 in the temperature storage 11 and / or freezer 12 to the window. When items need to be stored in the temperature storage 11 or freezer 12, the items are placed in the window. The controller controls the transfer component 31, which, after being controlled by the controller, places the items into the storage space 13 of the temperature storage 11 or freezer 12 as needed. When items need to be retrieved from the temperature storage 11 or freezer 12, the controller transfers the items from the temperature storage 11 or freezer 12 to the window via the temperature transfer component 311 and the freezer transfer component 312, where they are then manually retrieved.
[0034] Reference Figure 1 and Figure 2 The transfer unit 3 includes a transfer assembly 31 and a transfer track 32 for moving the rotating assembly. The transfer assembly 31 includes a temperature transfer component 311 and a freezing transfer component 312. The temperature transfer component 311 is located on one side of the temperature storage 11, and the freezing transfer component 312 is located on one side of the freezing storage 12. Optionally, the home cold storage is located in a villa, in which case the building itself is a villa building, and the storage unit 1 is located in the basement of the building. Multiple transfer tracks 32 are provided, and the multiple transfer tracks 32 are divided into two groups: one group of transfer tracks 32 is the temperature transfer track 321, and the other group of transfer tracks 32 is the freezing transfer track 322. The temperature transfer track 321 connects the storage space 13 in the temperature storage 11 to the windows in each room of the building, and the freezing transfer track 322 connects the storage space 13 in the freezing storage 12 to the windows in each room of the building.
[0035] Reference Figure 1 and Figure 2In use, the temperature transfer unit 311 transports items from the temperature storage 11 to the corresponding window in each room via the temperature transfer track 321, and the freezing transfer unit 312 transports items from the freezing storage 12 to the corresponding window in each room via the freezing transfer track 322. Separating the transport of items from the temperature storage 11 and the freezing storage 12 during retrieval improves efficiency and makes them more convenient to use. Both the optional freezing storage 12 and temperature storage 11 can be multi-story. The freezing storage 12 and temperature storage 11 are located within the villa, and their sizes are determined by the number of floors in the villa. Each floor of the villa is equipped with both the temperature transfer unit 311 and the freezing transfer unit 312. When cold storage is located within a villa, it is generally multi-story, and the size of the cold storage is determined by the size of the villa for ease of use.
[0036] Reference Figure 1 and Figure 2 Optionally, the temperature transfer component 311 is a temperature transfer robot, and the freezing transfer component 312 is a freezing transfer robot. Both the temperature transfer robot and the freezing transfer robot are equipped with a robotic arm or mechanical frame for picking up and placing items. In use, items can be placed in the mechanical frame or picked up by the robotic arm. The items placed in the mechanical frame or picked up by the robotic arm are moved by the temperature transfer component and the freezing transfer component 312.
[0037] Reference Figure 2 and Figure 3 The refrigeration system 2 provides refrigeration energy to the storage section 1 and includes a compressor 21, a flash heat exchanger 22, a liquid storage tank 23, and multiple pipes 24. The refrigeration system 2 is used to convert a refrigerant; in one embodiment of the invention, the refrigerant is carbon dioxide. The compressor 21 produces high-temperature, high-pressure carbon dioxide, the flash heat exchanger produces medium-temperature, medium-pressure carbon dioxide, and the medium-temperature, medium-pressure carbon dioxide is transferred to the liquid storage tank 23. The medium-temperature, medium-pressure carbon dioxide in the liquid storage tank 23 is throttled and converted into low-temperature, low-pressure carbon dioxide. The compressor 21, the flash heat exchanger, and the liquid storage tank 23 are each connected to one or more pipes 24. The pipes 24 include a high-temperature, high-pressure pipe 241, a medium-temperature, medium-pressure pipe 242, and a low-temperature, low-pressure pipe 243.
[0038] Reference Figure 2 and Figure 3The flash converter 22 is connected to the compressor 21 via a high-temperature, high-pressure pipe 241. The compressor 21 converts medium-temperature, medium-pressure carbon dioxide into high-temperature, high-pressure carbon dioxide. The flash converter 22 is connected to the storage tank 23 via a medium-temperature, medium-pressure pipe 242. The compressor 21 is connected to a low-temperature, low-pressure pipe 243. A low-temperature valve is installed on the low-temperature, low-pressure pipe 243 connected to the compressor 21. After passing through the low-temperature valve, the medium-temperature, medium-pressure carbon dioxide is converted into low-temperature, low-pressure carbon dioxide. The low-temperature, low-pressure carbon dioxide is connected to the ice-temperature storage 11 and the freezer 12 via the low-temperature, low-pressure pipe 243. The ice-temperature storage 11 and the freezer 12 are also connected to the low-temperature, low-pressure pipe 243 and the medium-temperature, medium-pressure pipe 242. Control valves are installed on the medium-temperature, medium-pressure pipe 242 near both the ice-temperature storage 11 and the freezer 12. The opening degree of the control valve on the medium-temperature, medium-pressure pipe 242 connected to the ice-temperature storage 11 is greater than that of the control valve on the medium-temperature, medium-pressure pipe 242 connected to the freezer 12. The control valve is used to control the flow rate of low-temperature, low-pressure gaseous carbon dioxide. For ice storage 11 and freezer 12, the opening degree of the control valve on the low-pressure pipe and medium-pressure pipe is controlled according to different needs, thereby adjusting the temperature inside ice storage 11 and freezer 12.
[0039] The refrigeration system 2 of this invention can be used not only for household cold storage but also for other energy-consuming components. The refrigeration system 2 can be converted into a carbon dioxide refrigeration and heating system. Buildings using the household cold storage of this invention can achieve zero-carbon construction through carbon dioxide, thus achieving energy conservation and emission reduction. A zero-carbon building includes a building body with an external insulation structure, a carbon dioxide refrigeration and heating system installed within the building body, solar panels installed on the exterior of the building body, solar collectors installed on the exterior of the building body, an energy storage device for storing heat from the solar collectors and / or the carbon dioxide refrigeration and heating system, and multiple energy-consuming components installed within the building body. These multiple energy-consuming components include heating components, refrigeration components, and heating / refrigeration components; the household cold storage of this invention is one type of refrigeration component.
[0040] The implementation principle of this application embodiment is as follows: The refrigeration system 2 is used to provide energy to the storage unit 1. The refrigeration system 2 is equipped with a refrigerant to be converted. The compressor 21 and the flash heat exchanger are used to convert the refrigerant into a low-temperature state for cooling the ice-temperature storage 11 and the freezer 12. Both the ice-temperature storage 11 and the freezer 12 are equipped with multiple storage spaces 13. Users can occupy one or more storage spaces 13 according to their own needs. This can meet the needs of families who do not have a refrigerator but occasionally need to freeze or refrigerate some items, as well as families who have a refrigerator but whose refrigerator storage space 13 is insufficient. In households with ample storage space 13, the ice-temperature storage 11 and freezer 12 are relatively large. The transfer unit 3 is used to retrieve items from the ice-temperature storage 11 and freezer 12 to different locations, or to transfer items from different locations to the ice-temperature storage 11 or freezer 12. The transfer track 32 is set in the ice-temperature storage 11, freezer 12, and the locations where items need to be retrieved or placed. The ice-temperature transfer unit 311 is used to transfer items that need to be iced or have already been iced back and forth, and the freezer 12 is used to transfer items that need to be frozen or have already been frozen back and forth, meeting different storage needs in daily life.
