In order that those skilled in the art will better understand the present invention, a technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.

It should be noted that, related information (including, but not limited to, user equipment information, user personal information, etc.) and data (including, but not limited to, data for presentation, analyzed data, etc.) related to the present disclosure are information and data authorized by a user or sufficiently authorized by each party. For example, an interface is provided between the system and the relevant user or institution, before acquiring the relevant information, the system needs to send an acquisition request to the user or institution through the interface, and acquire the relevant information after receiving the consent information fed back by the user or institution.

Fig. 1 is a block diagram of a cold source system according to an embodiment of the present application, and as shown in fig. 1, the cold source system includes: the system comprises a double-coil air conditioner, a water cooling system, an air cooling system, a natural cooling system, a first chilled water pipeline, a second chilled water pipeline and a control system; the double-coil air conditioner is used for cooling the data center; the double-coil air conditioner is connected with the water cooling system through a first chilled water pipeline and is connected with the air cooling system and the natural cooling system through a second chilled water pipeline; the second chilled water pipeline comprises an air cooling switching valve and a natural cooling switching valve, the air cooling switching valve is used for controlling chilled water circulation between the double-coil air conditioner and the air cooling system, and the natural cooling switching valve is used for controlling chilled water circulation between the double-coil air conditioner and the natural cooling system; the control system is electrically connected with the air-cooled switching valve and the natural cooling switching valve and is used for controlling the opening states of the air-cooled switching valve and the natural cooling switching valve according to the environmental state of the data center.

In this embodiment, the air cooling system, the water cooling system, and the natural cooling system are all heat dissipation systems for transferring heat generated in equipment or machinery of the data center to the environment to maintain the operating temperature of the data center within a safe and efficient range.

The double-coil air conditioner can also be called a double-coil precision air conditioner and is used for directly cooling a data center. A dual coil air conditioner is a particular type of air conditioning system in which "dual coil" refers to a system having two separate refrigeration circuits, each having its own coil (or evaporator). In this design, the air conditioning system can regulate the temperature and humidity more flexibly, and when one circuit is maintained, the other circuit can still continue to operate, thereby improving the reliability and redundancy of the system. Each coil is responsible for absorbing heat from the air in its circuit and transferring this heat through the refrigerant to the condenser. In a typical air conditioning system, a coil is positioned within the air conditioner and a refrigerant is circulated between the coil and a condenser to effect cooling and dehumidification of the indoor air. In this embodiment, the first chilled water line and the second chilled water line are two independent circuits in a dual coil air conditioner.

The air cooling system uses air as a cooling medium to dissipate heat. This is typically accomplished by fans or blowers that blow air across a heat sink or heat sink to reduce the temperature of the device. The air, as it flows over the heating surface, carries away heat, thereby cooling the device.

Water-cooled systems use water or other liquid as a cooling medium to transfer heat. In such systems, heat is typically transferred from a heat source to one or more heat sinks by a liquid coolant, which releases the heat to the surrounding environment through fins as the liquid flows within the heat sinks. Water-cooled systems are commonly used in applications where more efficient heat dissipation is required, such as large servers, high performance computers, and certain industrial facilities.

Natural cooling systems rely on natural processes such as thermal convection, radiation, and conduction to dissipate heat without the need for additional mechanical equipment (e.g., fans or pumps). For example, hot air rises due to its low density and cold air sinks, forming a natural convection cycle, which can carry away heat.

In this embodiment, maintenance personnel can adjust the valve opening based on the control system, and then realize the energy consumption regulation of whole cold source system, realize energy-conserving effect. The air cooling switching valve and the natural cooling switching valve can be respectively adjusted in opening degree by a control system, so that the accurate cold energy treatment proportion adjustment of the air cooling system and the natural cooling system is realized. Optionally, a maintainer can input a judging rule of the valve opening into the control system in advance, the control system monitors the environmental state of the data center, monitors the heat dissipation requirement of the data center, the operation working condition of the cold source system and the like, the control system automatically selects the most energy-saving valve opening scheme meeting the heat dissipation requirement of the data center, and then generates a control instruction based on the valve opening scheme to control the opening of each of the natural cooling switching valve and the air cooling switching valve, so that the aim of reducing the overall power consumption of the cold source system is fulfilled.

Based on the cold source system, the double-coil air conditioner is used for cooling a data center; the double-coil air conditioner is connected with the water cooling system through a first chilled water pipeline, and is connected with the air cooling system and the natural cooling system through a second chilled water pipeline; the second chilled water pipeline comprises an air cooling switching valve and a natural cooling switching valve, and controls chilled water circulation between the double-coil air conditioner and the air cooling system and chilled water circulation between the double-coil air conditioner and the natural cooling system respectively; the control system is used for controlling the opening states of the air cooling switching valve and the natural cooling switching valve according to the environmental state of the data center, so that the technical problem that the energy consumption of a cooling system of the data center is high is solved, and the technical effect of automatically reducing the overall power consumption of a cold source system of the data center is realized.

As an alternative embodiment, the water cooling system may include a water cooling chiller, a first water cooling cryopump, a second water cooling cryopump, and a second cooling tower; the second cooling tower is connected with a condenser of the water cooling water chilling unit, and the double-coil air conditioner is connected with an evaporator of the water cooling water chilling unit through a first chilled water pipeline.

As an alternative embodiment, the air-cooling system may include an air-cooled chiller and an air-cooled cryopump; the double-coil air conditioner is connected with an evaporator of the air-cooled chiller through a second chilled water pipeline.

As an alternative embodiment, the free cooling system may comprise a plate heat exchanger, a first free cooling cryopump, a second free cooling cryopump and a first cooling tower; the double-coil air conditioner is connected with the secondary side of the plate heat exchanger through a second chilled water pipeline, and the natural cooling switching valve and the first natural cooling refrigerating pump are positioned between the double-coil air conditioner and the plate heat exchanger; the primary side of the plate heat exchanger is connected with the first cooling tower, and the second natural cooling refrigerating pump is positioned between the primary side of the plate heat exchanger and the first cooling tower.

The cooling tower is a heat exchange device utilizing natural cooling principle, and has the main function of discharging the waste heat in the air conditioning system into the atmosphere in a water evaporation mode. In the cooling tower, hot water may flow from the system and be distributed within the cooling tower through spray heads or packing to increase the surface area of the water in contact with the air. As the air naturally rises within the cooling tower or is drawn by the fan through the water droplets, heat is transferred from the water to the air by evaporation and heat transfer, thereby cooling the water temperature. The design and operating efficiency of the cooling tower is important for energy conservation and reduced water resource consumption.

FIG. 2 is a schematic diagram of a cold source system according to an alternative embodiment of the present invention, as shown in FIG. 2, an air-cooled switching valve may include an air-cooled chilled water supply valve V1 and an air-cooled chilled water return valve V2; the natural cooling switching valve can comprise a natural cooling chilled water supply valve V3 and a natural cooling chilled water return valve V4, and also can comprise a natural cooling water inlet valve V5 and a natural cooling water outlet valve V6, wherein the valves V3 to V6 are valves on two sides of the plate heat exchanger.

As an alternative embodiment, the first cooling tower and the second cooling tower are connected through a cooling tower freezing water pipeline, and a cooling tower switching valve is arranged on the cooling tower freezing water pipeline.

The cooling tower switching valve may include a natural cooling tower switching valve 1 (V7) and a natural cooling tower switching valve 2 (V8) in fig. 2, among others. The cooling tower switching valve can control the communication relation between the first cooling tower and the second cooling tower, so that the control system can intelligently allocate the cooling tower to the natural cooling system or the water cooling system according to the energy consumption condition. For example, when the external environment of the data center is very cold, the natural cooling system is adopted to cool the chilled water, so that a better effect can be obtained, and the energy consumption is very low, the output of the water cooling unit can be reduced, the power of a water cooling freezing pump related to the water cooling unit is reduced, the opening degree of a switching valve of the cooling tower is increased, the natural cooling system can use the cooling tower in the water cooling system to cool more chilled water naturally, and the purpose of saving energy consumption is achieved. When the natural cooling effect is poor, the opening degree of the cooling tower switching valve can be reduced or the cooling tower switching valve is closed, and the cooling water of the double-coil air conditioner is cooled by the air cooling system and the water cooling system, so that the refrigeration requirement of the data center is met.

As an alternative embodiment, the cold source system may further include a temperature and humidity sensor, where the temperature and humidity sensor is electrically connected to the control system, and is configured to monitor an environmental state of the data center and send the environmental state of the data center to the control system.

In this optional embodiment, the temperature and humidity sensor may detect an environmental state of the data center, where the environmental state of the data center may include a temperature and humidity of an inside of the data center, or may include a temperature and humidity of an external environment where the data center is located, where these data information may be used as a basis for performing cold source circulation adjustment by the control system, for example, when the external environment temperature is low, for example, in winter, the cooling tower is used to naturally cool the chilled water, so that a better cooling effect may be obtained, and energy consumption may be reduced under a condition that a requirement for internal heat dissipation of the data center is met, and then the valve opening of the natural cooling switching valve may be adjusted to increase, and more chilled water may be introduced into the natural cooling system, and the cooling tower may cool the portion of chilled water; meanwhile, the opening degree of the air cooling switching valve of the air cooling system can be reduced, even the valve is closed, the energy consumption of the air cooling system is reduced, the dynamic adjustment of the energy consumption of the whole cold source system is realized, and meanwhile, the integral refrigerating effect of the cold source system is not influenced.

Optionally, when the external environment temperature is higher, for example, the current season is summer, or the heat dissipation requirement of the data center is higher, and the natural cooling system is simply adopted, the control system can analyze the above conditions to obtain a control instruction for increasing the opening of the air cooling switching valve, more chilled water is led into the air cooling system, the air cooling system performs active heat dissipation, the running power of the air cooling system is improved, the cooled chilled water is returned to the double-coil air conditioner as soon as possible, and the data center performs refrigeration and cooling.

Different cooling systems are greatly affected by weather, and if the two-way cold sources of the same data center adopt different cooling modes, the performance coefficient change trend of the different cooling modes is different along with the change of the environmental temperature and humidity. According to the method, the energy-saving optimal solution of the two paths of load ratio is calculated by utilizing the simulation model of the intelligent control system on the premise of ensuring the safe and stable operation of the data center by utilizing the characteristic that the performance coefficients of different cooling modes are different under different environment temperatures.
