Description

Technical Field

[0001] This application belongs to the field of infrastructure technology, specifically relating to a wind-liquid fusion refrigeration equipment, system, control method, device, medium, and product. Background Technology

[0002] Currently, traditional data center server rooms generally use air cooling. There is a cold source outdoors. However, since the chilled water required by the air cooling equipment is at a low temperature, it is difficult to reduce the temperature to such a low level by the outdoor cold source alone. Therefore, additional chiller units are required. Thus, the current traditional data center generally uses an outdoor cold source - chiller units - air cooling device inside the server room.

[0003] When air cooling is insufficient to meet the heat dissipation requirements of data center computer rooms, the data center computer rooms are modified to add liquid cooling devices. The liquid cooling devices and air cooling devices work independently and do not overlap, making it difficult to centrally control the liquid cooling devices and air cooling devices.

[0069] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0070] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0071] In this document, the term "and / or" merely describes a relationship, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. Furthermore, the term "at least one" in this document means any combination of at least two of any one or more elements. For example, including at least one of A, B, and C can mean including any one or more elements selected from the set consisting of A, B, and C.

[0072] With the continuous development of AI technology, the requirements for chip performance are getting higher and higher. While chips are being developed, they also bring higher heat dissipation. The heat dissipation is approaching the heat dissipation limit of the current air cooling technology, and the heat dissipation of chips is constantly increasing. It is necessary to consider the new situation of chip heat dissipation in the future. It is not difficult to see that under the high heat dissipation demand, liquid cooling will become the future development direction of the server temperature control industry. Liquid cooling technology is crucial for overcoming the challenges of AI cloud computing and can pave the way for ultra-large-scale cloud services.

[0073] Currently, traditional data center server rooms generally use air cooling. There is a cold source outdoors. However, since the chilled water required by the air cooling equipment is at a low temperature, it is difficult to reduce the temperature to such a low level by the outdoor cold source alone. Therefore, additional chiller units are required. Thus, the current traditional data center generally uses an outdoor cold source - chiller units - air cooling device inside the server room.

[0074] When air cooling is insufficient to meet the heat dissipation requirements of data center computer rooms, the data center computer rooms are modified to add liquid cooling devices. The liquid cooling devices and air cooling devices work independently and do not overlap, making it difficult to centrally control the liquid cooling devices and air cooling devices.

[0075] To alleviate the problems existing in related technologies, this application provides a combined air-liquid cooling device, system, control method, apparatus, medium, and product. The combined air-liquid cooling device includes an air-cooled device, a liquid-cooled device, a first delivery pipeline connected to both the liquid-cooled device and the air-cooled device, and a switching device. The opening parameter of the switching device determines the connection relationship between the liquid-cooled device and the air-cooled device. Using the solution of this embodiment, centralized control of both the liquid-cooled device and the air-cooled device is achieved through the cooperation of the switching device, thereby saving system energy consumption and improving cooling efficiency.

[0076] To facilitate understanding of this embodiment, a detailed description of the air-liquid fusion refrigeration device 400 disclosed in this application embodiment will be provided first, such as... Figure 1 As shown, the air-liquid fusion refrigeration equipment 400 may include:

[0077] Liquid cooling equipment 1, air cooling equipment 2, a first conveying pipeline 3 connected to the liquid cooling equipment 1 and the air cooling equipment 2 respectively, and a switching device 4 installed on the first conveying pipeline 3;

[0078] The opening parameter of the switching device 4 determines the connection relationship between the liquid cooling device 1 and the air cooling device 2.

[0079] In this embodiment, the opening parameter is used to characterize the opening degree of the switch device 4. Taking the range of the opening parameter of the switch device 4 from 0 to 10 as an example, when the opening parameter is 0, the switch device 4 is completely closed; when the opening parameter is 10, the switch device 4 is completely open; and when the opening parameter is a value between 0 and 10, the switch device 4 is partially open.

[0080] In this embodiment, the switching device 4 may include multiple switches. The opening and closing of these switches affect the direction of cooling water flow in the first delivery pipeline 3. Since both the liquid cooling device 1 and the air cooling device 2 are connected to the first delivery pipeline 3, the direction of cooling water flow determines the connection relationship between the liquid cooling device 1 and the air cooling device 2. For example, the liquid cooling device 1 and the air cooling device 2 can be connected in series or in parallel, thus realizing centralized control of the liquid cooling device 1 and the air cooling device 2 through a single pipeline.

[0081] In this embodiment, the liquid cooling device 1 and the air cooling device 2 can be housed in the same device or they can be two separate devices; this embodiment does not impose a specific limitation on this. As an example, when the liquid cooling device 1 and the air cooling device 2 are integrated into the same device, the following is provided: Figure 2 The image shown is a front view of a fusion cooling system 400 integrating a refrigeration unit and an air-cooling unit 2. (See image for reference.) Figure 2 As shown, the air-liquid fusion refrigeration equipment 400 includes a liquid cooling device 1 and an air cooling device 2, with the air cooling device 2 having an air outlet.

[0082] In this embodiment, the main components of the air-cooled device 2 include a fan, an air-liquid heat exchanger, and a proportional valve. The fan circulates air to regulate indoor temperature, humidity, and air quality. When the air-liquid fusion cooling device starts, the fan draws in indoor air, processes it through the air-liquid heat exchanger, and then returns it to the room. The air-liquid heat exchanger has inlet and outlet ports for cooling water from an outdoor cold source. The fan draws indoor air into the air-cooled device 2 and blows this air into the air-liquid heat exchanger. The indoor air and chilled water exchange heat through the air-liquid heat exchanger, achieving the purpose of cooling the air. The air then flows out from the outlet of the air-cooled device 2, achieving air-cooled control of the room. The proportional valve regulates the amount of chilled water entering the air-cooled device 2. The chilled water flowing out of the air-liquid heat exchanger mixes with the chilled water flowing out of the liquid cooling device 1 and is discharged through the first delivery pipeline 3.

[0083] In this embodiment, the main components of the liquid cooling device 1 include a water supply pump, a plate heat exchanger, a buffer tank, a water tank, and electric valves. When the air-liquid fusion cooling device is working, the cooling water flowing into the liquid cooling device 1 enters the plate heat exchanger for heat exchange, and then merges with the return water from the air cooling device 2, flowing out through the return water port of the air-liquid fusion cooling device. The liquid cooling device 1 is equipped with a secondary side pipeline, which is used to connect to the indoor liquid cooling device. When the air-liquid fusion cooling device is running, the cooling water from the outdoor cold source enters the plate heat exchanger and exchanges heat with the hot water from the indoor unit. After completing the heat exchange, the water enters the primary side return water pipeline of the liquid cooling device 1, and the indoor hot water becomes cold water and is supplied to the indoor liquid cooling device through the secondary side pipeline.

[0084] In one or more embodiments, such as Figure 1 As shown, the first delivery pipeline 3 includes a common water supply pipeline 31, a common return water pipeline 32, a bypass pipeline 33 connecting the common water supply pipeline 31 and the outlet of the air-cooled equipment 2, and an air-cooled return water pipeline 34 connecting the outlet of the air-cooled equipment 2 and the common return water pipeline 32; the switching device 4 includes a first switch 41 installed on the bypass pipeline 33, a second switch 42 installed on the air-cooled return water pipeline 34, and a third switch 43 installed on the common water supply pipeline 31;

[0085] The third switch 43 is located between the first connection point and the second connection point. The first connection point is the connection point between the bypass pipeline 33 and the public water supply pipeline 31. The second connection point is the connection point between the air-cooled water inlet pipeline and the public water supply pipeline 31. The air-cooled water inlet pipeline connects the water inlet of the air-cooled equipment 2 and the public water supply pipeline 31.

[0086] In this embodiment, by setting a first switch 41, a second switch 42, and a third switch 43, the air-cooled device 2 and the liquid-cooled device 1 can be connected in series for cooling. Specifically, when the third switch 43 and the second switch 42 are both in the closed state and the first switch 41 is in the open state, the air-cooled device 2 and the liquid-cooled device 1 are connected in series. The cooling water transported by the common water supply pipeline 31 flows into the air-cooled device 2 through the air-cooled water inlet pipeline and the water inlet of the air-cooled device 2, and then flows into the liquid-cooled device 1 through the water outlet of the air-cooled device 2, the first switch 41, and the water inlet of the liquid-cooled device 1, and finally flows out through the water outlet of the liquid-cooled device 1 and the common return water pipeline 32.

[0087] In one or more embodiments, such as Figure 1 As shown, the switching device 4 also includes:

[0088] The fourth switch 44 is installed on the air-cooled water inlet pipe.

[0089] A fourth switch 44 is installed on the air-cooled water inlet pipe, which can adjust the flow rate of the air-cooled water inlet pipe, making the flow rate of cooling water flowing in the air-cooled water inlet pipe controllable.

[0090] In one or more embodiments, such as Figure 3 As shown, the public water supply pipeline 31 includes a public water supply loop 311;

[0091] The switching device 4 also includes:

[0092] The fifth switch 45 and the sixth switch 46 are installed on the public water supply loop 311;

[0093] Both the fifth switch 45 and the sixth switch 46 are connected to the cold source inlet on the common water supply loop 311. At the same time, a first connection point, a second connection point, and a third connection point are provided between the fifth switch 45 and the sixth switch 46. The third connection point is the connection point between the liquid cooling water inlet pipe and the common water supply loop 311. The liquid cooling water inlet pipe connects the inlet of the liquid cooling equipment 1 to the common water supply loop 311.

[0094] By setting the fifth switch 45 and the sixth switch 46, the liquid cooling device 1 and the air cooling device 2 can be connected in parallel. The opening degree of the fifth switch 45 and the sixth switch 46 is adjustable, thus making the flow rate into the liquid cooling device 1 and the air cooling device 2 adjustable. When the fifth switch 45, the sixth switch 46 and the second switch 42 are all in the open state, and the first switch 41 and the third switch 43 are in the closed state, the cooling water flowing in the common water supply loop 311 enters the liquid cooling device 1 through the fifth switch 45 and the inlet of the liquid cooling device 1, and then flows out through the outlet of the liquid cooling device 1 and the common return water pipe 32. At the same time, the cooling water flowing in the common water supply loop 311 enters the air cooling device 2 through the sixth switch 46 and the inlet of the air cooling device 2, and then flows out through the outlet of the air cooling device 2, the second switch 42 and the common return water pipe 32.

[0095] It should be understood that when the switching device 4 also includes a fourth switch 44, the fourth switch 44 should also be in the open state when the liquid cooling device 1 and the air cooling device 2 are connected in parallel. Furthermore, the opening degree of the fourth switch 44 is adjustable according to actual needs.

[0096] In one or more embodiments, such as Figure 4 As shown, the common return water pipeline 32 includes a common return water loop 321; the cold source inlet includes a first cold source inlet and a second cold source inlet, and the common return water loop 321 is provided with a first cold source outlet corresponding to the first cold source inlet and a second cold source outlet corresponding to the second cold source inlet.

[0097] The switching device 4 also includes a seventh switch 47 and an eighth switch 48 installed on the common water supply loop 311, and a ninth switch 49 and a tenth switch 40 installed on the common water return loop 321.

[0098] The seventh switch 47 is located between the first cold source inlet and the second cold source inlet;

[0099] The eighth switch 48 is located between the third connection point and the fourth connection point. The fourth connection point is the connection point on the common water supply loop 311 that connects to the water inlet of the liquid cooling equipment 1.

[0100] The ninth switch 49 is located between the outlet of the first cold source and the outlet of the second cold source;

[0101] The tenth switch 40 is located between the fifth connection point and the sixth connection point. The fifth connection point is the connection point between the common return water loop 321 and the outlet of the liquid cooling equipment 1, and the sixth connection point is the connection point between the common return water loop 321 and the outlet of the air cooling equipment 12.

[0102] With the seventh switch 47, the eighth switch 48, the ninth switch 49, and the tenth switch 40 all in the closed state, the seventh switch 47, the eighth switch 48, the ninth switch 49, and the tenth switch 40 isolate the first cold source and the second cold source, and at the same time isolate the liquid cooling device 1 and the air cooling device 2, so that the cooling water flowing out of the inlet of the first cold source only flows into the liquid cooling device 1, and the cooling water flowing out of the inlet of the second cold source only flows into the air cooling device 2.

[0103] Specifically, the cooling water flowing out of the first cold source inlet flows into the liquid cooling device 1 through the first part of the common water supply loop between the seventh switch 47 and the eighth switch 48, and then flows out through the outlet of the liquid cooling device 1 and the first part of the common outlet loop between the ninth switch 49 and the tenth switch 40.

[0104] The cooling water flowing out of the second cold source flows into the air-cooled device 2 through the inlet of the air-cooled device 2 via the second part of the common water supply loop between the seventh switch 47 and the eighth switch 48, and then flows out through the outlet of the air-cooled device 2 and the second part of the common outlet loop between the ninth switch 49 and the tenth switch 40.

[0105] The air-liquid fusion refrigeration equipment provided in this embodiment includes an air-cooled device 2, a liquid-cooled device 1, a first delivery pipeline 3, and a switching device 4. The opening parameter of the switching device 4 determines the connection relationship between the liquid-cooled device 1 and the air-cooled device 2. Using the scheme of this embodiment, centralized control of the two refrigeration devices, liquid-cooled device 1 and air-cooled device 2, is achieved through the cooperation of the switching device 4, thereby saving system energy consumption and improving refrigeration efficiency.

[0106] This embodiment also provides a wind-liquid fusion refrigeration system, such as Figure 5 As shown, it may include:

[0107] Outdoor cold source 100, second delivery pipeline 200, indoor environment 300, and air-liquid fusion refrigeration equipment 400 in the aforementioned embodiment;

[0108] Cooling water flowing out of the outdoor cold source 100 is transported to the air-liquid fusion refrigeration equipment 400 via the second delivery pipeline 200, so as to achieve the cooling of the indoor environment 300 by the air-liquid fusion refrigeration equipment 400.

[0109] In this embodiment, the outdoor cold source 100 includes, but is not limited to, a water tower capable of outputting cooling water, corresponding pipelines, and pipeline supporting facilities (such as valves and pumps). In some scenarios, the outdoor cold source 100 may also include a chiller unit. When a chiller unit is included, initially, cooling water flows out of the cooling tower, collects in a circular supply network, and then enters the chiller unit through the circular network. Heat exchange occurs in the chiller unit, and the water after heat exchange collects in a circular return network, then returns to the cooling tower. The chilled water portion (i.e., primary side chilled water) first exchanges heat with the cooling water in the chiller unit. Then, the chilled water exits the chiller unit and enters the chilled water supply circular network. Branch pipes extend from the chilled water circular network to supply the air-liquid fusion refrigeration equipment 400. The return water from the air-liquid fusion refrigeration equipment 400 collects in the chilled water return network and then returns to the chiller unit.

[0110] It should be understood that Figure 5 The diagram only shows the water supply pipeline; the return pipeline is arranged similarly.

[0111] In applications, to improve cooling performance, settings such as... Figure 5 The multi-group air-liquid fusion refrigeration system shown is given as an example. Figure 6 The diagram shows the working principle of a combined air-liquid refrigeration system. Figure 6 As shown, the air-liquid fusion refrigeration system includes three refrigeration systems, each of which includes a cooling tower, a chiller unit, and a refrigeration device.

[0112] In one or more alternative embodiments, the second delivery pipeline 200 is a ring network pipeline.

[0113] The second delivery pipeline 200 is configured as a ring network, which helps improve the reliability of coolant delivery. Compared to ordinary pipelines, the ring network can still deliver coolant even if a fault occurs somewhere in it, thus improving reliability.

[0114] In one or more alternative embodiments, it further includes:

[0115] Control equipment that communicates with switch device 4;

[0116] The control device is used to determine the opening parameters of the switching device 4 based on the refrigeration parameters, and to control the switching device 4 to operate according to the opening parameters; the refrigeration parameters are used to characterize the degree of matching between the refrigeration capacity of the liquid cooling device 1 and / or the air cooling device 2 and the indoor refrigeration demand.

[0117] In this embodiment, flow sensors and temperature sensors are installed on both the primary and secondary supply and return water pipelines of the liquid cooling device 1, and a monitoring system is also provided. The monitoring system can display the primary and secondary supply and return water temperatures and flow rates of the liquid cooling device 1. The control device adjusts the primary side water inflow of the liquid cooling device 1 based on the temperature feedback from the monitoring system and the initial design temperature. When the air-liquid fusion refrigeration system is working, the secondary side supply and return water flow rates and temperatures of the liquid cooling device 1 need to be set according to the calculated cooling capacity relationship. The secondary side supply and return water flow rates are constant. When the secondary side supply and return water temperatures change, a control signal is generated and transmitted to the control device to make the system react. When the secondary side return water temperature is higher than the set temperature, the valve of the primary side liquid cooling device 1 is controlled to increase the flow rate into the liquid cooling device 1. When the secondary side return water temperature is lower than the set temperature, the valve is controlled to reduce the flow rate into the liquid cooling device 1.

[0118] Temperature sensors and flow sensors are installed on the primary side supply and return water pipelines of the air-cooled equipment 2. The monitoring system can display the inlet and outlet water temperatures of the air-cooled equipment 2. The fan maintains a certain operating power to keep the air volume entering the air-liquid fusion cooling system of the air-cooled equipment 2 constant. The control equipment can control the amount of primary side chilled water entering the air-cooled equipment 2 according to the set supply air temperature.

[0119] It should be understood that the control device can be a standalone device or it can be deployed in the switching device 4. This embodiment does not specifically limit this.

[0120] This application also provides a control method for a wind-liquid fusion refrigeration system, which can be applied to the wind-liquid fusion refrigeration system described in the foregoing embodiments, such as... Figure 7 As shown, the method may include the following steps:

[0121] Step 701: Based on the refrigeration parameters, determine the switching state of the switching device 4. The refrigeration parameters are used to characterize the degree of matching between the refrigeration capacity of the liquid cooling device 1 and / or the air cooling device 2 and the indoor refrigeration demand.

[0122] Step 702: Control the switch device 4 to operate according to the switch state.

[0123] The cooling capacity of liquid cooling device 1 is related to the inlet and outlet liquid temperatures of liquid cooling device 1. Similarly, the cooling capacity of air cooling device 2 is related to the inlet and outlet liquid temperatures of air cooling device 2. When determining the switching state of switch device 4 based on cooling parameters, the opening parameters of switch device 4 can be dynamically adjusted in real time based on the cooling capacity of liquid cooling device 1, the cooling capacity of air cooling device 2 and the initial opening parameters of switch device 4.

[0124] In a specific implementation, in one or more embodiments, determining the opening parameter of the switching device 4 based on the cooling parameters may include the following steps:

[0125] Based on the cooling parameters, including the outlet water temperature of the cold source, the initial opening parameters of the switching device 4 are determined.

[0126] When the switching device 4 is operating according to the initial opening parameters, the cooling capacity of the liquid cooling device 1 is calculated based on the collected inlet and outlet liquid temperatures of the liquid cooling device 1, and the cooling capacity of the air cooling device 2 is calculated based on the collected inlet and outlet liquid temperatures of the air cooling device 2.

[0127] Based on the cooling capacity of liquid cooling device 1, the cooling capacity of air cooling device 2, the heat dissipation calculated based on the target ambient temperature of indoor environment 300, and the initial opening parameters, the final opening parameters of switch device 4 are determined.

[0128] Regarding the initial opening parameters, in the case of a single cold source, when the temperature of the cooling water flowing out of the outdoor cold source 100 is relatively low, if the evaluation shows that the outlet temperature of the cold source from the single cold source can cover the heat dissipation of both the air-cooled device 2 and the liquid-cooled device 1, and the water temperature after heat exchange in the air-cooled device 2 can still meet the inlet temperature requirements of the liquid-cooled device 1, then the air-cooled device 2 and the liquid-cooled device 1 are connected in series. This is achieved through a switching device 4 (such as a valve) so that the primary side cooling water can only enter the air-cooled device 2 first, and then the liquid-cooled device 1. That is, the primary side cooling water first enters the air-cooled device 2, exchanges heat with it, and then the outlet water from the air-cooled device 2 re-enters the water supply loop, and then enters the liquid-cooled device 1. After heat exchange in the liquid-cooled device 1, it enters the return water loop. In this case, the entire loop is configured for unidirectional flow. The water supply in the system is then set according to the greater demand of either the air-cooled device 2 or the liquid-cooled device 1.

[0129] In this case, the switching device 4 includes a first switch 41, a second switch 42 and a third switch 43;

[0130] Based on the cooling parameters, including the outlet water temperature of the cold source, the initial opening parameters of the switching device 4 are determined, including:

[0131] When the cold source outlet water temperature is less than or equal to the temperature threshold, the air-cooled return water temperature is collected. The air-cooled return water temperature is the temperature of the return water after the cooling water passes through the air-cooling device 2.

[0132] When the air-cooled return water temperature is less than or equal to the preset inlet water temperature of the liquid cooling equipment 1, the initial opening parameters of the second switch 42 and the third switch 43 are determined to indicate that the switches are closed, and the initial opening parameter of the first switch 41 indicates that the switches are open.

[0133] When the air-cooled return water temperature is greater than the preset inlet water temperature of the liquid cooling equipment 1, the initial opening parameter of the second switch 42 indicates that the switch is closed, and the initial opening parameters of the first switch 41 and the third switch 43 indicate that the switch is open.

[0134] The fact that the cold source outlet water temperature is less than or equal to the temperature threshold indicates that the cold source outlet water temperature can cover the heat dissipation of both the air-cooled device 2 and the liquid-cooled device 1. Both the temperature threshold and the preset inlet water temperature of the liquid-cooled device 1 can be preset based on experience or actual needs; this embodiment does not impose specific limitations on these settings.

[0135] The fact that the air-cooled return water temperature is less than or equal to the preset inlet water temperature of the liquid cooling device 1 indicates that the water temperature after the air-cooled part heats up can still meet the liquid inlet temperature requirements of the liquid cooling part. Therefore, the liquid cooling device 1 and the air-cooled device 2 are connected in series by a switch setting.

[0136] In one or more embodiments, if the water from a single cold source no longer meets the inlet temperature requirement of the liquid cooler 1 after passing through the air-cooled device 2, the control system adjusts the pump speed to make the total primary flow rate of the system equal to the sum of the required flow rates of the liquid cooler 1 and the air-cooled device 2. Then, the proportional valve is adjusted to ensure that the flow rates entering the air-cooled device 2 and the liquid cooler 1 are the set flow rates. At this time, the water circuits of the liquid cooler 1 and the air-cooled device 2 are connected in parallel. Cold water from the cold source can directly enter the liquid cooler 1 and the air-cooled device 2 through the same supply pipe. After heat exchange, the water then flows into the drainage pipe and is finally discharged from the primary side outlet. Both the supply and return water pipes are fully open at this time.

[0137] In this case, the switching device 4 includes a first switch 41, a second switch 42, a third switch 43, a fifth switch 45, and a sixth switch 46;

[0138] Based on the cooling parameters, including the outlet water temperature of the cold source, the initial opening parameters of the switching device 4 are determined, which may include:

[0139] When the outlet water temperature of the cold source is greater than the temperature threshold, the required flow rate of each of the air-cooled device 2 and the liquid-cooled device 1 is estimated based on the preset inlet water temperature of the air-cooled device 2 and the preset inlet water temperature of the liquid-cooled device 1.

[0140] The initial opening parameters of the fifth switch 45 and the sixth switch 46 are determined based on the flow rate. The initial opening parameters of the first switch 41 and the third switch 43 are determined to indicate that the switches are closed, and the initial opening parameter of the second switch 42 is determined to indicate that the switches are open.

[0141] In one or more embodiments, when dual cold sources are input, both inlets and two outlets on the refrigeration unit integrating liquid cooling device 1 and air cooling device 2 are opened, and the corresponding valves are opened to allow flow. The air-cooled loop and the liquid-cooled loop are disconnected through the valve settings. At this time, the air-cooled loop and the liquid-cooled loop operate independently, with water entering the air-cooled section directly and water entering the liquid-cooled section directly. During system operation, the flow rate can be adjusted by regulating the proportional valve.

[0142] In this case, the switching device 4 includes a seventh switch 47, an eighth switch 48, a ninth switch 49, and a tenth switch 40;

[0143] Based on the cooling parameters, including the outlet water temperature of the cold source, the initial opening parameters of the switching device 4 are determined, including:

[0144] Based on the dual-cold-source input mode included in the refrigeration parameters, the initial opening parameters of the seventh switch 47, the eighth switch 48, the ninth switch 49, and the tenth switch 40 are determined to all represent the switch being closed.

[0145] It should be understood that the air-liquid fusion refrigeration system supports users in selecting the cold source mode. The cold source modes include single cold source input mode and dual cold source input mode. The single cold source input mode is used to indicate that the outdoor cold source 100 is a single cold source, while the dual cold source input mode is used to indicate that the outdoor cold source 100 is a dual cold source, that is, the liquid cooling device 1 and the air cooling device 2 each correspond to one cold source.

[0152] Based on the cooling capacity of the liquid cooling device 1, the cooling capacity of the air cooling device 2, the heat dissipation calculated based on the target ambient temperature of the indoor environment 300, and the initial opening parameters, the final opening parameters of the switching device 4 are determined.

The return water temperature of the air-cooled water is the temperature of the return water after the cooling water passes through the air-cooling device 2.

[0156] When the air-cooled return water temperature is less than or equal to the preset inlet water temperature of the liquid cooling device 1, the initial opening parameters of the second switch 42 and the third switch 43 indicate that the switch is closed, and the initial opening parameter of the first switch 41 indicates that the switch is open.

[0157] When the air-cooled return water temperature is greater than the preset inlet water temperature of the liquid cooling device 1, the initial opening parameter of the second switch 42 is determined to be closed, and the initial opening parameter of the first switch 41 and the third switch 43 is determined to be open.
