Description

Technical Field

[0001] This utility model relates to the field of water-based cooling, and in particular to a water distribution system. Background Technology

[0002] In the field of water-based cold storage system technology, hot and cold water stratification and circulation are usually achieved by installing water distributors at the top and bottom of the cold storage tank. The water distributor at the bottom is connected to the outlet of the cold storage unit and is used to inject low-temperature cold water, while the water distributor at the top is connected to the inlet of the unit and is used to extract relatively high-temperature hot water. Stable temperature stratification is maintained by the density difference formed by the temperature difference.

[0003] However, the above-mentioned cold storage method will form a sloped temperature layer with a temperature gradient inside the cold storage tank, especially when the cold water injection volume reaches half of the tank volume, this transition zone is particularly obvious; the water temperature in the sloped temperature layer shows a clear vertical gradient distribution, and the water temperature is lower the farther away from the top water distributor. When the chilled water storage unit continuously draws water from the top water distributor, the outlet water temperature will continue to drop as it approaches the low-temperature thermocline. Once the water temperature falls below the operating threshold set by the chilled water storage unit, the unit will initiate a protective shutdown. At this time, the warm water in the thermocline at the top of the tank cannot meet the operating requirements of the chilled water storage unit due to insufficient temperature, but it occupies the effective volume of the chilled water storage tank, forming a state of "ineffective cold energy" storage. This results in a significant reduction in the actual usable volume of the chilled water storage tank. This volume loss can reach up to 30% of the total volume, which restricts the system's chilled water storage efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a water distribution system that, through the coordinated operation of two water distributors, simultaneously extracts and mixes hot water and warm water from the thermocline, thereby increasing the volume of cold water.

[0005] The technical solution adopted by the water distribution system disclosed in this utility model is: The device includes a cold storage unit, a first solenoid valve, a second solenoid valve, a cold storage unit, and a cold-consuming end. The cold storage unit is provided with a first water distribution assembly, a second water distribution assembly, and a third water distribution assembly from top to bottom. A first diverter is connected between the first water distribution assembly and the second water distribution assembly. The first diverter is connected to one end of the first solenoid valve. A one-way valve is provided on the second water distribution assembly. A second diverter is connected to the third water distributor. The second diverter is connected to one end of the second solenoid valve. The inlet of the cold storage unit and the outlet of the cold-consuming end are both connected to the other end of the first solenoid valve. The outlet of the cold storage unit and the inlet of the cold-consuming end are both connected to the other end of the second solenoid valve.

[0006] As a preferred embodiment, the first water distribution assembly includes a plurality of first water distributors, the first water distributors being connected to a first diverter seat; the second water distribution assembly includes a plurality of second water distributors, the second water distributors being connected to the first diverter seat; the one-way valve is a plurality of such valves, the one-way valves being installed inside the second water distributors; and the third water distribution assembly includes a plurality of third water distributors, the third water distributors being connected to the second diverter seat.

[0007] As a preferred embodiment, a third solenoid valve is connected between the outlet of the cold end and the other end of the first solenoid valve.

[0008] As a preferred embodiment, a fourth solenoid valve is connected between the outlet of the cold storage unit and the other end of the second solenoid valve.

[0009] As a preferred embodiment, a first water pump is connected between the inlet of the cold storage unit and the other end of the first solenoid valve.

[0010] As a preferred embodiment, a second water pump is connected between the inlet of the cold end and the other end of the second solenoid valve.

[0011] As a preferred embodiment, the one-way valve includes a mounting base, a valve plate is rotatably connected inside the mounting base, a spring is provided on the valve plate, the spring contacts the mounting base, and the mounting base is snapped into the second water distributor.

[0012] As a preferred embodiment, a limiting ring extends inside the second water distributor, and the mounting base touches the limiting ring.

[0013] The beneficial effects of the water distribution system disclosed in this utility model are: When the cold storage device needs to perform cold water storage operations, the cold end stops operating, and the first and second solenoid valves open simultaneously. The cold water storage unit begins producing cold water and injects it into the cold storage device through the third water distribution assembly. Simultaneously, the cold water storage unit extracts hot water from the cold storage device via the first solenoid valve, the first diverter seat, the check valve, the first water distribution assembly, and the second water distribution assembly. As cold water continues to be injected, the thermocline inside the cold storage device gradually rises, causing the hot water extracted by the first water distribution assembly to be at a higher temperature than the warm water extracted by the second water distribution assembly. The mixture of the cooler warm water and the warmer hot water allows the combined hot water temperature to reach the preset minimum operating temperature of the cold water storage unit. This hot water extraction method helps to extract more hot water from the thermocline, thereby increasing the cold water storage capacity and improving the overall cold water storage efficiency of the cold storage device.

[0014] When the user needs cooling, the cold storage unit stops operating. The user draws cold water from the cold storage device through the third water distribution component. After heat exchange is completed at the user, the cold water is converted into hot water and then reinjected into the cold storage device through the first solenoid valve and the first water distribution component. During this process, the one-way valve prevents the hot water from flowing through the second water distribution component, thus preventing the hot water from entering the thermocline and preventing the thermocline water temperature from rising, thereby maintaining the stability of the thermocline.

[0015] When the cold water storage in the cold storage device is insufficient, the first solenoid valve and the second solenoid valve close simultaneously, the cold storage host starts and produces cold water, directly providing cooling capacity to the user end, while the hot water generated by the user end flows back to the cold storage host.

[0018] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings: Please refer to Figure 1 .

[0019] The present invention discloses a water distribution system, including a cold storage device 1, a first solenoid valve V1, a second solenoid valve V2, a cold storage host 2, and a cold end 3; In this embodiment, the preferred cold storage device 1 is a cold storage tank, but it is not limited to this.

Furthermore, the first water distributor 11 is located at the top of the cold storage device 1, and the liquid level in the cold storage device 1 is above the first water distributor 11, which is used to extract hot water or inject hot water; the second water distributor 12 is located in the middle of the cold storage device 1, which is used to extract warm water from the thermocline; and the third water distributor 13 is located at the bottom of the cold storage device 1, which is used to extract cold water or inject cold water. Water from the first water distributor 11 and the second water distributor 12 can flow through the first diverter seat 111 to one end of the first solenoid valve V1 and mix at the first diverter seat 111.

[0020] The second water distribution assembly is provided with a one-way valve 4. In this embodiment, it is preferred that there are multiple one-way valves 4, and the number of one-way valves 4 is the same as the number of the second water distributor 12. Furthermore, a one-way valve 4 is installed inside the second water distributor 12. The one-way valve 4 is used to prevent water from flowing from the first diverter seat 111 to the second water distributor 12, but does not restrict water from flowing from the second water distributor 12 to the first diverter seat 111.

[0021] The inlet of the cold storage unit 2 is connected to the other end of the first solenoid valve V1, and the outlet of the cold storage unit 2 is connected to the other end of the second solenoid valve V2. Furthermore, a first water pump 21 and a first three-way valve are connected between the inlet of the cold storage unit 2 and the other end of the first solenoid valve V1; the outlet of the first water pump 21 is connected to the inlet of the cold storage unit 2, the inlet of the first water pump 21 is connected to the first three-way valve, and the other end of the first solenoid valve V1 is connected to the first three-way valve; so that the first water pump 21 can draw water from the first water distributor 11 and the second water distributor 12 through the first three-way valve, the first solenoid valve V1 and the first diverter seat 111, and deliver it to the cold storage unit 2 to produce cold water; Furthermore, a fourth solenoid valve V4 and a second three-way valve are connected between the outlet of the cold storage unit 2 and the other end of the second solenoid valve V2; one end of the fourth solenoid valve V4 is connected to the second three-way valve, the outlet of the cold storage unit 2 is connected to the other end of the fourth solenoid valve V4, and the other end of the second solenoid valve V2 is connected to the second three-way valve; so that the cold storage unit 2 injects the generated cold water into the third water distributor 13 through the fourth solenoid valve V4, the second three-way valve, the second solenoid valve V2, and the second diverter seat 131.

[0022] The outlet of cold end 3 is connected to the other end of the first solenoid valve V1, and the inlet of cold end 3 is connected to the other end of the second solenoid valve V2. In this embodiment, cold end 3 is preferably used as a heat exchanger. Furthermore, a third solenoid valve V3 is connected between the outlet of the cold end 3 and the other end of the first solenoid valve V1; one end of the third solenoid valve V3 is connected to the first three-way valve, and the other end of the third solenoid valve V3 is connected to the outlet of the cold end 3; so that the hot water converted after heat exchange at the cold end 3 can be injected into the first water distributor 11 through the third solenoid valve V3, the first three-way valve, the first solenoid valve V1 and the first diverter seat 111. Furthermore, a second water pump 31 is connected between the inlet of the cold end 3 and the other end of the second solenoid valve V2; the inlet of the second water pump 31 is connected to the second three-way valve, and the outlet of the second water pump 31 is connected to the inlet of the cold end 3; so that the second water pump 31 can draw water from the third water distributor 13 through the second three-way valve, the second solenoid valve V2, and the second diverter seat 131, and deliver it to the cold end 3 for heat exchange.

[0023] Please refer to Figure 2 .

[0024] The pipe wall of the second water distributor 12 extends into a limit ring 121, which is used to engage the check valve 4. Furthermore, the one-way valve 4 includes a mounting base 41. In this embodiment, the mounting base 41 is preferably a hollow annular shape. A valve plate 42 is rotatably connected to the inner wall of the mounting base 41. A limiting block extends from the inner wall of the mounting base 41. The valve plate 42 touches the limiting block, and the limiting block is used to limit the rotation direction of the valve plate 42. Furthermore, a spring 421 is provided on the valve plate 42, and a slot is provided on the valve plate 42. One end of the spring 421 is inserted into the slot, thereby fixing the spring 421 on the valve plate 42. A protrusion extends from the inner wall of the mounting base 41, and the other end of the spring 421 touches the protrusion, so that the spring 421 can push the valve plate 42 to cover the mounting base 41 and touch the limiting block. When water flows from the second distributor 12 to the first diverter seat 111, the water flow pushes the valve plate 42 to rotate and open on the mounting seat 41, and compresses the spring 421, thereby allowing water to flow through; when water flows from the first diverter seat 111 to the second distributor 12, the valve plate 42 loses the water flow thrust, and is reset and closed on the mounting seat 41 under the action of the spring 421 rebound force, while abutting against the limit block, thereby blocking the water flow path.

[0025] Please refer to Figure 1 and Figure 2 .

[0026] This system has three operating modes: Cold storage mode: When the cold end 3 stops operating, the first solenoid valve V1, the second solenoid valve V2 and the fourth solenoid valve V4 are opened, and the third solenoid valve V3 is closed to prevent the first water pump 21 from drawing water from the heat exchanger and to keep the water flow in the cold end 3 still. The first water pump 21 draws hot water from the cold storage device 1 and delivers it to the cold storage host 2 via the first three-way valve, the first solenoid valve V1, the first diverter seat 111, the one-way valve 4, the first water distributor 11, and the second water distributor 12. After the cold storage host 2 cools the hot water into cold water, it injects it into the cold storage device 1 through the fourth solenoid valve V4, the second three-way valve, the second solenoid valve V2, the second diverter seat 131, and the third water distributor 13. During this process, the water flow at the cold end 3 is still to prevent cold water from entering the cold end 3. As cold water is continuously injected, the temperature gradient inside the cold storage device 1 gradually rises, causing the hot water temperature drawn by the first water distributor 11 to be higher than the warm water drawn by the second water distributor 12. However, by mixing the two in the first distribution seat 111, the temperature of the mixed water reaches the preset minimum operating temperature of the cold storage host 2, thereby enabling more hot water to be drawn from the temperature gradient, increasing the cold water storage capacity, and improving the overall cold storage efficiency.

[0027] Cooling mode: The cold storage unit 2 stops running, the first solenoid valve V1, the second solenoid valve V2 and the third solenoid valve V3 are opened, and the fourth solenoid valve V4 is closed to prevent the second water pump 31 from drawing water from the cold storage unit 2 and to make the water flow in the cold storage unit 2 stagnant. The second water pump 31 draws cold water from the cold storage device 1 and delivers it to the cooling end 3 via the second three-way valve, the second solenoid valve V2, the second diverter seat 131, and the third water distributor 13. After heat exchange at the cooling end 3, the cold water becomes hot water and then flows back to the cold storage device 1 via the third solenoid valve V3, the first three-way valve, the first solenoid valve V1, the first diverter seat 111, and the first water distributor 11. During this process, the water flow in the cold storage host 2 is stagnant, which can prevent hot water from entering the cold storage host 2. At the same time, the one-way valve 4 prevents hot water from flowing back through the second water distributor 12, thus preventing hot water from entering the thermocline and maintaining the temperature stability of the thermocline.

[0028] Direct supply mode: The first solenoid valve V1 and the second solenoid valve V2 are closed, the third solenoid valve V3 and the fourth solenoid valve V4 are open, and the cold storage unit 2 starts cooling. The second water pump 31 draws chilled water from the cold storage unit 2 via the second three-way valve and the fourth solenoid valve V4 and delivers it to the cooling end 3. The chilled water completes heat exchange at the cooling end 3 and becomes hot water. The first water pump 21 draws hot water after heat exchange from the cold end 3 via the first three-way valve and the third solenoid valve V3, and delivers it to the cold storage unit 2, thereby enabling the cold storage unit 2 to directly supply cooling to the cold end 3 and recover the hot water after heat exchange to the cold storage unit 2.

[0029] This invention provides a water distribution system. When a cold storage device needs to be used for cold storage operations, the cold end stops operating, and the first and second solenoid valves open simultaneously. The cold storage unit begins to produce cold water and injects it into the cold storage device through a third water distribution assembly. Simultaneously, the cold storage unit extracts hot water from the cold storage device via the first solenoid valve, the first diverter seat, the check valve, the first water distribution assembly, and the second water distribution assembly. As cold water continues to be injected, the thermocline inside the cold storage device gradually rises, causing the temperature of the hot water extracted by the first water distribution assembly to be higher than the temperature of the warm water extracted by the second water distribution assembly. The mixture of the lower-temperature warm water and the higher-temperature hot water allows the combined hot water temperature to reach the preset minimum operating temperature of the cold storage unit. This hot water extraction method helps to extract more hot water from the thermocline, thereby increasing the cold water storage capacity and improving the overall cold storage efficiency of the cold storage device.

[0030] When the user needs cooling, the cold storage unit stops operating. The user draws cold water from the cold storage device through the third water distribution component. After heat exchange is completed at the user, the cold water is converted into hot water and then reinjected into the cold storage device through the first solenoid valve and the first water distribution component. During this process, the one-way valve prevents the hot water from flowing through the second water distribution component, thus preventing the hot water from entering the thermocline and preventing the thermocline water temperature from rising, thereby maintaining the stability of the thermocline.

[0031] When the cold water storage in the cold storage device is insufficient, the first solenoid valve and the second solenoid valve close simultaneously, the cold storage host starts and produces cold water, directly providing cooling capacity to the user end, while the hot water generated by the user end flows back to the cold storage host.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
