[0033] See also Figure 1 The energy-saving cooling system in the preferred embodiment of the utility model includes a storage container 101, which is connected to a first transmission pipeline, the first transmission pipeline includes a first inlet pipe 102 and a first outlet pipe 103, wherein the first inlet pipe 102 is used for inputting the medium to be cooled, and the first outlet pipe 103 is used for outputting the medium to be cooled; a first cooling mechanism 120, the first cooling mechanism 120 cools down the medium to be cooled by a working medium, wherein the working medium can exchange heat with the external environment, and then cools down the medium to be cooled by the working medium, the first cooling mechanism 120 forms a transmission loop with the storage container 101 through a second transmission pipeline, and the medium to be cooled flowing through the storage container 101 can be introduced into the first cooling mechanism 120 for cooling; and a second cooling mechanism 121, the second cooling mechanism 121 forms a transmission loop with the storage container 101 through a third transmission pipeline, and the second cooling mechanism 121 is a cooling device, which cools the medium to be cooled by refrigeration. Among them, the above-mentioned first inlet pipe 102 is connected to the first branch pipe 104 and the second branch pipe 105, the first branch pipe 104 is connected to the storage container 101, and the second branch pipe 105 is connected to the first cooling mechanism 120, and the first switch valve 106 and the second switch valve 107 are respectively arranged on the first branch pipe 104 and the second branch pipe 105.

[0034] Specifically, the present application simultaneously sets a first cooling mechanism 120 and a second cooling mechanism 121 in the energy-saving cooling system, wherein the temperature of the working medium in the first cooling mechanism 120 depends on the ambient temperature, and the working medium cools down the medium to be cooled, and the operation of the first cooling mechanism 120 will not significantly increase the energy consumption; the second cooling mechanism 121 cools down by internal refrigeration, and the two are used in combination to reduce the system energy consumption while ensuring the cooling efficiency of the energy-saving cooling system; and the first cooling mechanism 120 and the second cooling mechanism 121 can back up each other, and when the first cooling mechanism 120 or the second cooling mechanism 121 fails, the cooling method can be switched and another cooling mechanism can be used for temporary cooling to ensure that the working medium to be cooled is maintained in a relatively reasonable temperature range. In addition, the present application sets a second branch pipe 105, so that in addition to circulating cooling between the storage container 101 and the first cooling mechanism 120, the medium to be cooled can also flow directly through the first cooling mechanism 120 for pre-cooling, and then introduce the second cooling mechanism 121 for cooling, which can ensure efficient cooling of the cooling system on the one hand, and reduce cooling power consumption on the other hand. At the same time, the first switch valve 106 and the second switch valve 107 in the present application are used to select a cooling path for the medium to be cooled. When the energy-saving cooling system is actually working, the first switch valve 106 and the second switch valve 107 are opened one by one to ensure that the medium to be cooled is transmitted and cooled from one of the paths.

[0035] Preferably, the storage container 101 in the present application serves as a transit storage structure for the medium to be cooled, which can deliver the medium to be cooled into the first cooling mechanism 120 and / or the second cooling mechanism 121, and can perform circulation cooling between the cooling mechanisms to ensure that the medium to be cooled output from the storage container 101 reaches the set temperature. The storage container 101 can be optionally a water tank.

[0036] Further preferably, the first cooling mechanism 120 in the present application is a cooling water tower or a cooling water pool, and the second cooling mechanism 121 is a refrigerator. When the temperature of the medium to be cooled is too high, it can be cooled by a cooling water tower or a cooling water pool. When the target temperature cannot be reached or the efficiency is too slow, the medium to be cooled can be introduced into the refrigerator, and the refrigerator itself can be refrigerated to achieve rapid cooling of the medium to be cooled to reach the set target temperature.

[0037] Optionally, when the first cooling mechanism 120 in the present application is a cooling water tower, its internal working medium is spray water, and the second transmission pipeline is cooled by the spray water to achieve cooling of the medium to be cooled therein.

[0038] Optionally, the second transmission pipeline includes a second inlet pipe 108 and a second outlet pipe 109, and the second branch pipe 105 is connected to the pipeline of the second inlet pipe 108. The second branch pipe 105 and the second inlet pipe 108 can be connected to the first cooling mechanism 120 separately, but this will increase the length of the pipeline in the energy-saving cooling system, and the medium to be cooled flowing through the second branch pipe 105 also needs to flow into the storage container 101, so the second branch pipe 105 must be connected to the second inlet pipe 108 or the second outlet pipe 109 to deliver the medium to be cooled into the storage container 101. Therefore, the present application connects the second branch pipe 105 to the second inlet pipe 108 before the second inlet pipe 108 enters the first cooling mechanism 120, which can reduce the length of the second branch pipe 105.

[0039] Meanwhile, it is worth noting that the cooling medium in the first cooling mechanism 120 is preferably water, and it may also be other fluids with larger specific heat capacity.

[0040] Further preferably, the second branch pipe 105 and the second inlet pipe 108 in the present application are respectively provided with a first check valve 110 and a second check valve 111, and the second check valve 111 is provided at one end of the second inlet pipe 108 adjacent to the storage container 101. The second branch pipe 105 and the second inlet pipe 108 share a part of the pipeline, and the two are used to deliver the medium to be cooled into the first cooling mechanism 120. There is no selectivity when the medium to be cooled flows in the pipeline. The medium to be cooled may flow from the second branch pipe 105 through the second inlet pipe 108 to the storage container 101, or the working medium may flow from the second inlet pipe 108 through the second branch pipe 105 to the inlet of the medium to be cooled, resulting in the energy-saving cooling system being unable to achieve a cooling effect. The present application is provided with a first check valve 110 and a second check valve 111. When the medium to be cooled flows through the second branch pipe 105 or the second inlet pipe 108, the other pipeline is closed to ensure that the medium to be cooled flows into the first cooling mechanism 120 for cooling. Correspondingly, the first one-way valve 110 in the present application is open in the direction of the second branch pipe 105 toward the first cooling mechanism 120, and the first cooling mechanism 120 is closed in the direction of the second branch pipe 105; the second one-way valve 111 is open in the direction of the second inlet pipe 108 toward the first cooling mechanism 120, and the first cooling mechanism 120 is closed in the direction of the second inlet pipe 108, so as to prevent the backflow of the medium to be cooled. Optionally, the first one-way valve 110 and the second one-way valve 111 can also adopt a valve body structure that directly closes the second branch pipe 105 and the second inlet pipe 108.

[0041] It is worth noting that since the second branch pipe 105 and the second inlet pipe 108 share part of the pipeline, in order to prevent the second one-way valve 111 from being able to control the cooling medium to flow back from the second inlet pipe 108 to the storage container 101, the second one-way valve 111 is arranged at one end of the second inlet pipe 108 adjacent to the storage container 101.

[0042] Further preferably, the first inlet pipe 102 and the first outlet pipe 103 in the present application are respectively provided with a first temperature sensor 112 and a second temperature sensor 113. The first temperature sensor 112 and the second temperature sensor 113 on the first inlet pipe 102 and the first outlet pipe 103 are respectively used to monitor the temperature of the incoming medium to be cooled and the temperature of the outgoing medium to be cooled. The temperature of the medium to be cooled is detected by the first temperature sensor 112 to select different cooling conditions, and ensure that the medium to be cooled is reduced to the target temperature while reducing energy consumption; the second temperature sensor 113 is used to detect the temperature of the medium to be cooled after cooling to ensure that the medium to be cooled has been reduced to the target temperature.

[0043] Further preferably, the first cooling mechanism 120 in the present application is provided with a third temperature sensor 114. Since the first cooling mechanism 120 in the present application relies on the ambient temperature for cooling, the present application accordingly sets a third temperature sensor 114 in the first cooling mechanism 120 to detect the temperature of the working medium in the first cooling mechanism 120 in real time, so as to facilitate the energy-saving cooling system to adjust the cooling condition according to the temperature of the medium to be cooled, the temperature of the working medium in the first cooling mechanism 120, and the target temperature of the medium to be cooled.

[0044] Further preferably, the third transmission pipeline in the present application includes a third inlet pipe 115 and a third outlet pipe 116, the third inlet pipe 115 is used to send the medium to be cooled in the storage container 101 to the second cooling mechanism 121 for cooling, and the third outlet pipe 116 is used to send the cooled medium to be cooled back to the storage container 101. At the same time, the third inlet pipe 115 and / or the third outlet pipe 116 are also provided with a first circulating water pump 117, which is used to provide transmission power, so that the medium to be cooled between the storage container 101 and the second cooling mechanism 121 is circulated and cooled between the two, ensuring that the medium to be cooled is discharged through the storage container 101 after being reduced to the target temperature.

[0045] Preferably, the first outlet pipe 103 is further provided with a first output pump 118, and the first output pump 118 is used to deliver the cooled medium in the storage container 101 to the original pipeline.

[0046] Furthermore, the second inlet pipe 108 is provided with a second output pump 119, and the second output pump 119 is used to send the medium to be cooled in the storage container 101 to the first cooling mechanism 120 for cooling.

[0047] As an optional embodiment of the utility model, the first cooling mechanism 120 in the present application includes a cooling water tower, which is connected to an external water source, and the third temperature sensor 114 is arranged in the cooling water tower. The cooling water source stored in the cooling water tower itself is limited. After heat exchange with the medium to be cooled, its temperature will rise, which is difficult to meet the demand for continuous cooling of the medium to be cooled. Therefore, the cooling water tower can be connected to an external water source, and the water source in the cooling water tower is exchanged with the external water source to ensure that the water source in the cooling water tower is maintained at the ambient temperature. Correspondingly, the third temperature sensor 114 is arranged in the cooling water tower, which can know the actual temperature of the water source, avoid the temperature difference between the external ambient temperature and the water source temperature, and affect the final cooling effect of the medium to be cooled.

[0048] It is worth noting that the refrigeration capacity of the working medium in the first cooling mechanism 120 is affected by seasonal and environmental changes, and its temperature will change accordingly, and the temperature of the medium to be cooled may also change according to different working requirements, so various cooling conditions may occur. The energy-saving cooling system is adjusted to different working modes according to different cooling conditions:
