Description

Technical Field

[0001] The present application relates to the technical field of energy storage equipment, and in particular to a water storage cooling device for a central air conditioner. Background Art

[0002] Energy storage equipment refers to a device that can store energy in some form and release it when needed to supply the system or equipment. The function of energy storage equipment is to buffer and balance the energy supply and demand, thereby improving energy utilization efficiency and enhancing the stability and reliability of the system. A water chilled storage device is a technical device that uses water as a heat medium, stores heat by cooling with low-temperature water during off-peak hours, and then releases the stored cold during peak hours for use by air-conditioning systems or other equipment.

[0003] In the patent document with the published announcement number CN203719008U, a water storage cooling device is provided, including a water storage tank and a water distribution pipeline, an upper water distributor and a lower water distributor arranged in the water storage tank, the upper water distributor and the lower water distributor are both connected to the water distribution pipeline; the upper water distributor and / or the lower water distributor include a plurality of horizontally arranged water distribution discs, each of which includes a first water inlet and outlet located at the upper part or the lower part, a second water inlet and outlet located at the periphery, and a water inlet and outlet connecting the first water inlet and outlet to the second water inlet and outlet. The interlayer is connected with the water inlet and outlet; the diameter of the water distribution disc is much smaller than the geometric size of the corresponding water distribution section of the water reservoir, and the water distribution disc of the upper water distributor is evenly distributed over the upper water distribution section of the water reservoir, and the water distribution disc of the lower water distributor is evenly distributed over the lower water distribution section of the water reservoir. The utility model makes the scattered flow length within the unit water distribution section equal or the number of water distribution discs equal, so that water can slowly and evenly enter and exit the water reservoir to maintain a stable inclined temperature layer with appropriate thickness, thereby improving the cold storage efficiency.

[0004] When storing water, the above-mentioned device utilizes the principle that water with higher temperature automatically rises and water with lower temperature automatically falls, so as to separate hot and cold water, thereby obtaining warmer water and colder water, and the two types of water are located in the upper and lower layers of the reservoir respectively. As the temperature gradually decreases over time, the cold water area becomes larger and larger, and finally the effect of natural cooling is achieved. Firstly, the cooling efficiency of the above-mentioned device is low through natural cooling.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0031] Reference Figure 1 A water storage device for a central air conditioner includes a storage mechanism 1, a conveying pipe 2 is installed at the rear end of the storage mechanism 1, a closing mechanism 3 is installed at the front end of the storage mechanism 1, a cooling mechanism 4 is installed at the front end of the storage mechanism 1, and conveying mechanisms 5 are installed and connected on both sides of the cooling mechanism 4, and the conveying mechanism 5 is installed inside the storage mechanism 1.

[0032] Reference Figure 1 , 3 The storage mechanism 1 includes a cold storage box 101, a mounting groove 102 is provided in the middle of the front end of the cold storage box 101, the cooling mechanism 4 is installed inside the mounting groove 102, the inner walls on both sides of the cooling mechanism 4 are fixedly connected with mounting blocks 103, and the conveying mechanism 5 is installed on the mounting blocks 103. The mounting blocks 103 are responsible for supporting the conveying mechanism 5, and the mounting groove 102 is responsible for providing an installation position for the cooling mechanism 4. The cold storage box 101 is responsible for storing cooling water, thereby maintaining the overall cold storage function. The cold storage box 101 is a horizontal circular cylinder, which can expand the upper surface area of ​​the cooling water, thereby improving the cooling efficiency.

[0033] Reference Figure 2 The closing mechanism 3 includes a baffle 301, the upper end of which is hinged to the upper end of the mounting groove 102, two door closers 303 are installed on both sides of the front of the baffle 301, the upper end of the door closer 303 is installed at the front end of the cold storage box 101, and a handle 304 is fixedly connected to the middle of the front of the baffle 301. When it is necessary to observe the cooling mechanism 4, the baffle 301 can be pulled open by the handle 304, and the working condition of the cooling mechanism 4 inside the mounting groove 102 can be observed, and the door closer 303 can maintain the stable state of the baffle 301 when it is opened or closed.

[0034] Reference Figure 2A heat preservation plate 302 is installed directly below the baffle 301, and the size of the heat preservation plate 302 is the same as the opening size of the installation slot 102. When the closing mechanism 3 is in the closed state, the heat preservation plate 302 is completely embedded in the opening of the installation slot 102, thereby reducing the heat conduction efficiency between the installation slot 102 and the outside, improving the heat insulation effect of the closing mechanism 3, and maintaining the cooling effect of the cooling mechanism 4.

[0035] Reference Figure 2 The cooling mechanism 4 includes an installation box 401, the bottom of which is installed at the bottom of the installation slot 102, a small refrigerator 402 is installed at the top of the installation box 401, and an observation port 403 is provided in the front of the installation box 401, on which a glass plate 404 is installed. A certain amount of liquid water is stored in the installation box 401, and the liquid water is intermittently cooled by the small refrigerator 402. The implementation status inside the installation box 401 can be observed through the observation port 403 and the glass plate 404. The cooling mechanism 4 and the cold storage box 101 are isolated from each other, and heat is conducted through the cooling mechanism 4. When it is necessary to clean or disassemble and replace the cooling mechanism 4 components, it is not necessary to disassemble the cold storage box 101. When it is necessary to clean the cold storage box 101, it will not affect the cooling mechanism 4, so that the internal environment of the cold storage box 101 is prevented from being polluted, and it also makes it more convenient to maintain each mechanism.

[0036] Reference Figure 2 Two centrifugal pumps 405 are installed on both sides of the installation box 401. The interiors of the two centrifugal pumps 405 are connected to the interior of the installation box 401. The pipe opening of the centrifugal pump 405 at one end away from the installation box 401 penetrates the wall of the installation slot 102 and is then installed and connected to the conveying mechanism 5. Among the two centrifugal pumps 405, one centrifugal pump 405 is responsible for pumping water out of the cold storage box 101 and sending it to the inside of the conveying mechanism 5, and the other centrifugal pump 405 is responsible for pumping water from the inside of the conveying mechanism 5 to send water to the inside of the cold storage box 101, thereby realizing the circulation operation of cooling water. At the same time, the intermittent operation time of the centrifugal pump 405 and the small refrigerator 402 is the same to ensure the cooling effect.

[0037] Reference Figure 3The conveying mechanism 5 includes two main pipes 501, which are installed on both sides of the installation groove 102. The two main pipes 501 are connected and connected with the centrifugal pump 405. The two main pipes 501 are connected and connected with two distribution pipes 502 on the side away from the installation groove 102. The two distribution pipes 502 are connected and connected with multiple branch pipes 503 on the side. The multiple branch pipes 503 are connected and connected with a connecting pipe 504 on the side away from the distribution pipe 502. The distribution pipes 502, the branch pipes 503, the connecting pipe 504, and the cooling mechanism 4 form a circulating and connected passage. The cooling water enters the distribution pipe 502 through the main pipe 501, and after passing through multiple branch pipes 503, it is collected in the connecting pipe 504, and then enters the branch pipes 503 on the other side, the distribution pipe 502, and the main pipe 501 in turn through the connecting pipe 504, thereby realizing the circulation operation of the cold water in the conveying mechanism 5.

[0038] Reference Figure 3 The distribution pipe 502, the branch pipe 503, and the connecting pipe 504 are installed at the upper end of the cold storage box 101. The water at the top of the cold storage box 101 is generally at a higher temperature and has a lower density. When the water is cooled and sinks under the action of the conveying mechanism 5, the water with a higher temperature and a lower density will be squeezed to the upper part, and the cycle will be repeated, thereby improving the cooling effect.

[0039] Working principle: The mounting block 103 is responsible for supporting the conveying mechanism 5, the mounting groove 102 is responsible for providing an installation position for the cooling mechanism 4, and the cold storage box 101 is responsible for storing cooling water, thereby maintaining the overall cold storage function. The cold storage box 101 is a horizontal circular cylinder, which can expand the upper surface area of ​​the cooling water, thereby improving the cooling efficiency. When it is necessary to observe the cooling mechanism 4, the baffle 301 can be pulled open by the handle 304, and the working condition of the cooling mechanism 4 inside the mounting groove 102 can be observed. The door closer 303 can maintain the stable state of the baffle 301 when it is opened or closed. When the closing mechanism 3 is in the closed state, the insulation plate 302 is completely embedded in the opening of the mounting groove 102, thereby reducing the heat conduction efficiency between the mounting groove 102 and the outside world, and improving the heat insulation effect of the closing mechanism 3, so as to maintain the cooling effect of the cooling mechanism 4. A certain amount of liquid water is stored inside the installation box 401, and intermittent cooling of the liquid water is achieved through a small refrigerator 402. The implementation of the installation box 401 can be observed through the observation port 403 through the glass plate 404. The cooling mechanism 4 and the inside of the cold storage box 101 are isolated from each other, and heat is conducted through the cooling mechanism 4. When it is necessary to clean or disassemble and replace the cooling mechanism 4 components, it is not necessary to disassemble the cold storage box 101. When it is necessary to clean the cold storage box 101, it will not affect the cooling mechanism 4, avoiding the internal environment of the cold storage box 101 from being polluted, and also making it more convenient to maintain each mechanism;

[0040] Among the two centrifugal pumps 405, one centrifugal pump 405 is responsible for pumping water out of the cold storage tank 101 and sending it to the inside of the conveying mechanism 5, and the other centrifugal pump 405 is responsible for pumping water from the inside of the conveying mechanism 5 to send water to the inside of the cold storage tank 101, thereby realizing the circulation operation of cooling water. At the same time, the intermittent operation time of the centrifugal pump 405 and the small refrigerator 402 are the same to ensure the cooling effect. The cooling water enters the distribution pipe 502 through the main pipe 501, and after passing through multiple branch pipes 503, it is collected into the inside of the connecting pipe 504, and then enters the branch pipe 503 on the other side, the distribution pipe 502, and the main pipe 501 in turn through the connecting pipe 504, thereby realizing the circulation operation of cold water in the conveying mechanism 5. The water at the top of the cold storage tank 101 is generally higher in temperature and lower in density. When the water temperature is cooled and sinks under the action of the conveying mechanism 5, it will squeeze the water with higher temperature and lower density to the top, so as to circulate back and forth, thereby improving the cooling effect.

[0041] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and utility model concept of the present application, which should be covered by the protection scope of the present application.
