DETAILED DESCRIPTION

[0040] The following will describe the implementation methods of the present application with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific implementation methods, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for illustrating the present application, not for limiting the scope of protection of the present application.

[0041] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application, and thus the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0042] In the following description, a large number of details are discussed to provide a more thorough explanation of the embodiments of the present application. However, it is obvious to those skilled in the art that the embodiments of the present application can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present application difficult to understand.

[0043] See also Figure 1 , Figure 1 Schematic diagram of a chiller cooling water circulation control system according to an exemplary embodiment of the present application. Figure 1 It can be seen that the refrigerator cooling water circulation control system may include:

[0044] A first refrigeration circuit and a second refrigeration circuit.

[0045] The first refrigeration circuit includes a first three-way valve 101, a second three-way valve 102, a cooling component 103, a third three-way valve 104, and a refrigeration object cooling zone 105, which are connected in sequence through pipelines to form a loop; the cooling component 103 includes two refrigerators, namely a first refrigerator 1031 and a second refrigerator 1032, and the second three-way valve 102 and the third three-way valve 104 are used to divert the coolant so that the coolant flows through the first refrigerator 1031 or the second refrigerator 1032.

[0046] The second refrigeration circuit includes a first three-way valve 101, a cooling box group 106, a second three-way valve 102, a cooling component 103, a third three-way valve 104, and a refrigeration object cooling zone 105, which are connected in sequence through pipelines to form a loop; the first three-way valve 101 is used to divert the coolant so that the coolant flows through the first refrigeration circuit or the second refrigeration circuit, and the cooling box group 106 includes two cooling boxes, which are used to alternately naturally cool the coolant after heat exchange.

[0047] The refrigerator in the cooling assembly 103 cools the coolant after natural cooling.

[0048] In one embodiment of the present application, in a first refrigeration circuit, a first end of the first three-way valve 101 is connected to a first end of the second three-way valve 102, a second end of the second three-way valve 102 is connected to an inlet end of a refrigerator in the cooling assembly 103, a third end of the second three-way valve 102 is connected to an inlet end of another refrigerator in the cooling assembly 103, an outlet end of one refrigerator in the cooling assembly 103 is connected to a first end of the third three-way valve 104, an outlet end of another refrigerator in the cooling assembly 103 is connected to a second end of the third three-way valve 104, a third end of the third three-way valve 104 is connected to an inlet end of a cooling zone 105 of a refrigeration object, and an outlet end of the cooling zone 105 of a refrigeration object is connected to the second end of the first three-way valve 101.

[0049] In one embodiment of the present application, in the second refrigeration circuit, the third end of the first three-way valve 101 is connected to the inlet end of the cooling box group 106, and the outlet end of the cooling box is connected to the first end of the second three-way valve 102. The connection method of other equipment pipelines is consistent with the connection method in the first refrigeration circuit and will not be repeated here.

[0050] In addition, a water valve d may be provided on the outlet pipe of each cooling box in the cooling box group 106. When the water valve d is opened, the coolant in the corresponding cooling box can be used for circulating cooling. A water valve d may be provided on the inlet pipe of each cooling box in the cooling box group 106. When the water valve d is opened, the coolant after heat exchange can be naturally cooled in the corresponding cooling box.

[0051] It should be noted that Figure 1 The direction of the arrow in the middle represents the flow direction of the coolant. The coolant can be water, ethylene glycol and its mixture, propylene glycol, mineral oil or fluorinated liquid, etc.

[0052] In one embodiment of the present application, the refrigeration object may be industrial equipment, and the refrigeration object may include power generation equipment, chemical equipment, metal processing equipment, electronic equipment or machinery manufacturing, etc. In order to maintain the normal operating temperature of industrial equipment, improve efficiency and extend service life, a cooling zone is often set in the industrial equipment to pass coolant, and the refrigeration object cooling zone 105 in the embodiment of the present application may be a cooling zone of industrial equipment.

[0053] In one embodiment of the present application, the refrigerator can quickly cool the coolant, and the refrigerator can include a refrigeration module a, a heat exchange module b, and a water tank. The refrigeration module a can include a compressor, and the heat exchange module b can be an evaporator.

[0054] The compressor is responsible for sucking in low-pressure and low-temperature gaseous refrigerant and compressing it into high-temperature and high-pressure gas through mechanical action. After entering the condenser, the high-temperature and high-pressure gaseous refrigerant exchanges heat with the external environment or cooling medium, thereby releasing heat and gradually cooling down to become liquid. The liquid refrigerant coming out of the condenser will be rapidly depressurized when passing through the expansion valve, causing its temperature to drop sharply, becoming a low-temperature and low-pressure liquid or a gas-liquid mixture, ready to enter the evaporator. As the last link of the refrigeration cycle, the low-temperature and low-pressure refrigerant in the evaporator absorbs heat from the cooled object and evaporates into a gaseous state. This process cools the cooled object and achieves the purpose of refrigeration. At the same time, the vaporized refrigerant returns to the compressor again and starts a new cycle. The water tank can be used to store coolant, which is pumped into the condenser to help take away the heat of the refrigerant, and then returns to the water tank for recooling. This design helps to maintain the stable operation of the system and can effectively utilize water resources.

[0055] See also Figure 2 , which is a schematic diagram showing the coolant flowing through the first cooling circuit according to an exemplary embodiment of the present application. Figure 2 In the figure, the dashed arrow indicates the direction of coolant flow. Figure 2 It can be seen that when the coolant flows through the first cooling circuit, one of the two refrigerators can be activated first to cool the coolant. For example, the first refrigerator 1031 can be activated first to cool the coolant. At this time, the second refrigerator 1032 can cool the coolant in its water tank, but the coolant cooled by the second refrigerator 1032 does not circulate in the system. The coolant cooled by the first refrigerator 1031 flows through the cooling object cooling area 105 and exchanges heat with the cooling object to cool the cooling object. Figure 3 , which is a schematic diagram showing the coolant flowing through the first cooling circuit according to another exemplary embodiment of the present application. Figure 3 In the figure, the dashed arrow indicates the direction of coolant flow. Figure 3 It can be seen that when the refrigeration demand of the refrigeration object changes and requires more refrigeration capacity, or the water tank temperature of the first refrigerator 1031 has not yet dropped to a usable temperature, the second refrigerator 1032 can be enabled to cool the refrigeration object with the coolant refrigerated by the second refrigerator 1032, and the first refrigerator 1031 can be suspended. At this time, the first refrigerator 1031 can refrigerate the coolant in its water tank, but the coolant refrigerated by the first refrigerator 1031 is not circulated in the system.

[0056] See also Figure 4 , which is a schematic diagram showing the coolant flowing through the second cooling circuit according to an exemplary embodiment of the present application. Figure 4 In the figure, the dashed arrow indicates the direction of coolant flow. Figure 4It can be seen that when the coolant flows through the second cooling circuit, one of the two refrigerators can be activated to cool the coolant first. For example, the second refrigerator 1032 can be activated to cool the coolant first, and the coolant after heat exchange can be discharged to the first cooling box (any cooling box in the cooling box group), and the coolant in the second cooling box is used for heat exchange circulation. The second refrigerator 1032 cools the coolant in the second cooling box. Through such a setting, one of the two cooling boxes can be used alternately to cool the coolant naturally. The coolant after heat exchange can be discharged to one cooling box first for natural cooling, and the coolant in the other cooling box can be used by the refrigerator to quickly cool the coolant. The cooling speed of the coolant by the refrigerator can be accelerated. When the cooling demand of the cooling object is high, the overload phenomenon of the refrigerator can be avoided, and the life of the refrigerator can be increased.

[0057] In one embodiment of the present application, the refrigerator cooling water circulation control system may also include: a third refrigeration circuit, including a liquid inlet pipe 107, a cooling box group 106, a second three-way valve 102, a cooling component 103, a third three-way valve 104, a refrigeration object cooling zone 105, a first three-way valve 101, and a drain pipe 108 connected in sequence through pipelines; the liquid inlet pipe 107 is connected to a liquid supply device to provide new coolant through the liquid inlet pipe 107, and the coolant after heat exchange is discharged through the drain pipe 108.

[0058] The inlet end of the liquid inlet pipe 107 can be connected to the liquid supply device, the outlet end of the liquid inlet pipe 107 can be connected to the inlet end of the cooling box group 106, the outlet end of the cooling area 105 of the refrigeration object can be connected to the inlet end of the discharge pipe 108, and the outlet end of the discharge pipe 108 can be connected to the device for storing the discharge liquid. The connection method of other equipment pipelines is consistent with the connection method in the first refrigeration circuit, and will not be repeated here.

[0059] See also Figure 5 , which is a schematic diagram showing the coolant flowing through the third cooling circuit according to an exemplary embodiment of the present application. Figure 5 In the figure, the dashed arrow indicates the direction of coolant flow. Figure 5It can be seen that when the coolant flows through the third cooling circuit, one of the two refrigerators can be activated first to cool the coolant. For example, the second refrigerator 1032 can be activated first to cool the coolant. The new coolant provided by the liquid inlet pipe 107 can be refrigerated and then transported to the cooling area 105 of the refrigeration object to cool the refrigeration object, and the coolant after heat exchange is discharged from the system through the discharge pipe 108. When the two refrigerators are used alternately for cooling, the new coolant can be transported to the two cooling boxes, and the second refrigerator 1032 cools the coolant in the first cooling box. During the process of transporting the coolant refrigerated by the second refrigerator 1032 to the refrigeration object, the first refrigerator 1031 can cool the coolant in its cooling water tank. After the coolant refrigerated by the second refrigerator 1032 completes the heat exchange, the first refrigerator 1031 can be activated to cool the refrigeration object with the coolant refrigerated by the first refrigerator 1031. In this way, the refrigerators are all used to cool the new coolant. Compared with cooling the coolant circulating in the system, this solution can reduce the cooling time of the coolant by the refrigerator. When the cooling demand of the refrigeration object is high, the combination of two refrigerators and two cooling boxes can be used to alternately operate to increase the cooling speed of the coolant. The temperature of the coolant can be quickly reduced to the required temperature, reducing the cooling time of the coolant, avoiding overload of the refrigerator, and realizing uninterrupted cooling of the refrigeration object.

[0060] In one embodiment of the present application, the drain pipe 108 is disposed at the bottom of the cooling box. By disposing the drain pipe 108 at the bottom of the cooling box, the coolant can be first collected uniformly to one cooling box, and when drainage is required, the coolant can be discharged from the cooling box by gravity, and new coolant can be injected into another cooling box through the liquid inlet pipe 107. A water valve d can be disposed on the drain pipe 108, and the coolant can be discharged from the cooling box when the water valve d is opened.

[0061] In another possible implementation, a fourth three-way valve can be connected to the pipeline connected to the third end of the first three-way valve 101, the first end of the fourth three-way valve can be connected to the third end of the first three-way valve 101, the second end of the fourth three-way valve can be connected to the inlet end of the cooling box group 106, and the third end of the fourth three-way valve can be connected to the drain pipe 108. Such an arrangement can facilitate the discharge of the coolant, and the new coolant can directly enter the cooling box through the inlet pipe 107, and the coolant after heat exchange can be directly discharged through the drain pipe 108, which can accelerate the circulation of the coolant.

[0062] In one embodiment of the present application, a first circulation pump 109 is provided on the connecting pipeline between the refrigeration object cooling zone 105 and the third three-way valve 104 .

[0063] In one embodiment of the present application, a second circulation pump 110 is provided on the connecting pipeline at the outlet end of the cooling box group 106 .

[0064] It should be noted that the circulating pump can be used to increase the pressure of the cooling water circulation control system of the refrigerator to promote the circulation of the coolant in each cooling circuit to ensure that the temperature of the refrigeration object is within the appropriate temperature range.

[0065] When the refrigerator (including the first refrigerator 1031 and the second refrigerator 1032) and the circulating pump (including the first circulating pump 109 and the second circulating pump 110) are working, the refrigerator and the circulating pump are both working at the optimal power. The refrigerator and the circulating pump can be respectively adjusted within their respective optimal operating power ranges. The optimal operating power range of the circulating pump can be 80% to 100% of the rated power, and the optimal operating power range of the refrigerator can be 70% to 100% of the rated power.

[0066] In one embodiment of the present application, the refrigerator cooling water circulation control system may also include: a first temperature detection module 111 for detecting the temperature of the outlet end of the cooling zone 105 of the refrigeration object, a second temperature detection module 112 for detecting the temperature of each cooling box in the cooling box group 106, a third temperature detection module 113 for detecting the temperature of the cooling water tank c of the first refrigerator 103μ, and a fourth temperature detection module 114 for detecting the temperature of the cooling water tank c of the second refrigerator 1032.

[0067] The temperature detection module can be a temperature sensor or a thermal imager. When the temperature detection module is a temperature sensor, the first temperature detection module 111 can be set on the pipeline at the outlet end of the cooling zone 105 of the refrigeration object, the number of the second temperature detection modules 112 can correspond to the number of cooling boxes, the second temperature detection module 112 can be set on the surface of each cooling box, the third temperature detection module 113 can be set on the surface of the cooling water tank c of the first refrigerator 1031, and the fourth temperature detection module 114 can be set on the surface of the cooling water tank c of the second refrigerator 1032.

[0068] Detecting the various temperatures of the refrigerator cooling water circulation control system can facilitate the control of the refrigerator cooling water circulation control system, so as to switch each cooling circuit and refrigerator when the temperature meets the preset conditions, and cool the refrigeration object through the corresponding cooling circuit and refrigerator.

[0069] Figure 6 FIG. 1 is a flow chart of a chiller cooling water circulation control method shown in an exemplary embodiment of the present application. The chiller cooling water circulation control method can be applied to the chiller cooling water circulation control system provided in any of the above embodiments. Figure 6 As shown, the exemplary refrigerator cooling water circulation control method includes:

[0070] Step S610, obtaining a first cooling temperature.

[0071] The first cooling temperature is the temperature of the cooling water tank of the activated refrigerator in the cooling assembly.

[0072] In one embodiment of the present application, the first cooling temperature may be acquired by a second temperature detection module disposed on the surface of a cooling water tank of the refrigerator.

[0073] Step S620, when the first cooling temperature is greater than or equal to the first preset value, turn off the enabled refrigerator in the cooling assembly, and enable another refrigerator in the cooling assembly, so that the two refrigerators in the cooling assembly cool alternately.

[0074] In one embodiment of the present application, when the first cooling temperature is greater than or equal to a first preset value, an enabled refrigerator in the cooling assembly is turned off, and another refrigerator in the cooling assembly is enabled, so that the two refrigerators in the cooling assembly cool alternately.

[0075] In a possible implementation, the enabled refrigerator may use the coolant circulating in the refrigerator cooling water circulation control system for cooling.

[0076] In another possible implementation, the activated refrigerator alternately uses the coolant in the two cooling tanks for cooling.

[0077] Exemplarily, another refrigerator in the cooling assembly can be a second refrigerator, and the coolant in the first cooling box can be transported to the second refrigerator for cooling. The coolant cooled by the second refrigerator is transported to the cooling area of ​​the refrigeration object to cool the refrigeration object, and the coolant after heat exchange in the cooling area of ​​the refrigeration object can be discharged to the first cooling box for natural cooling. While cooling the refrigeration object, the coolant in the second cooling box can be transported to the second refrigerator to achieve alternating use of refrigerators and cooling boxes, so as to increase the cooling speed, reduce the probability of overloading the refrigerator, and increase the life of the refrigerator.

[0078] In one embodiment, the chiller cooling water circulation control method provided in the embodiment of the present application may further include steps S710 to S730.

[0079] Step S710, obtaining a second cooling temperature.

[0080] The second cooling temperature is the cooling water tank temperature of the refrigerator that is not enabled in the cooling assembly.

[0081] In one embodiment of the present application, the second cooling temperature may be acquired by a second temperature detection module disposed on the surface of a cooling water tank of the refrigerator.

[0082] Step S720, when the second cooling temperature is greater than or equal to the second preset value, and the difference between the first water tank temperature and the first preset value is less than or equal to the preset difference, new coolant is injected into the first cooling box through the liquid inlet pipe, and the coolant circulating in the pipeline is discharged to the second cooling box in the cooling box group, and discharged through the drain pipe connected to the second cooling box.

[0083] In one embodiment of the present application, when the second cooling temperature is greater than or equal to the second preset value, and the difference between the first water tank temperature and the first preset value is less than or equal to the preset difference, it indicates that the enabled refrigerator can no longer cool the coolant to the required temperature in a short time, and even if the unenabled refrigerator is enabled, it cannot meet the cooling demand of the refrigeration object. At this time, new coolant can be injected into the first cooling box through the liquid inlet pipe, and the coolant circulating in the pipeline is discharged to the second cooling box in the cooling box group, and discharged through the drain pipe connected to the second cooling box, so that the coolant after cooling by the refrigerator can meet the cooling demand of the refrigeration object. The first cooling box is any one of the two cooling boxes, and the second cooling box is the other of the two cooling boxes.

[0084] Step S730: transport the new coolant in the first cooling box to the activated refrigerator for cooling.

[0085] In one embodiment of the present application, the new coolant in the first cooling box can be transported to the activated refrigerator for cooling. The new coolant has a lower temperature than the coolant after heat exchange, which can increase the cooling speed of the refrigerator.

[0086] In one embodiment, the refrigerator cooling water circulation control method may also include: when the first cooling temperature is less than the first preset value, the second cooling temperature is less than the first cooling temperature, the real-time temperature of the cooling zone of the refrigeration object is greater than the third preset value, and the temperature change rate of the cooling zone of the refrigeration object is greater than the fourth preset value, shutting down the enabled refrigerator in the cooling component and enabling another refrigerator in the cooling component.

[0087] For example, Tn is the temperature of the cooling object at the nth moment, Tn-1 is the temperature of the cooling object at the n-1th moment, Δt is the time difference between the nth moment and the n-1th moment, then the temperature change rate V of the cooling object is Tn =(Tn-Tn-1) / Δt.

[0088] The third preset value may be 55°C, the fourth preset value may be 0, the first preset value may be 45°C, and the second preset value may be 30°C. In the current state, the water tank of the enabled refrigerator is connected to the refrigeration object for cooling. When the water tank temperature of the enabled refrigerator is 38.8°C, the water tank temperature of the disabled refrigerator is 33.2°C, which is less than 38.8°C, and the real-time temperature of the refrigeration object is detected to be 55.6°C, which is greater than the third preset value of 55°C, the temperature change rate V of the refrigeration object Tn It is 0.14, which is greater than the fourth preset value, indicating that continuing to use the enabled refrigerator to cool the refrigeration object can no longer control the refrigeration object within the preset temperature range. You can switch to connect the unenabled refrigerator to cool the refrigeration object, so as to quickly cool the refrigeration object to the preset temperature range for normal operation, so as to avoid affecting the normal operation and production of the refrigeration object.

[0089] An embodiment of the present application also provides an electronic device, comprising: one or more processors; a storage device for storing one or more programs, when the one or more programs are executed by one or more processors, the electronic device implements the refrigerator cooling water circulation control method provided in the above-mentioned embodiments.

[0090] Another aspect of the present application further provides a computer-readable storage medium on which a computer program is stored. When the computer program is executed by a processor of a computer, the computer executes the chiller cooling water circulation control method provided in each of the above embodiments. The computer-readable storage medium may be included in the electronic device described in the above embodiments, or may exist independently without being assembled into the electronic device.
