Description

Technical Field

[0001] The utility model relates to the field of vaccine manufacturing, in particular to an energy-saving and consumption-reducing device for a tank low-temperature storage refrigerated water system. Background Art

[0002] In the field of vaccine manufacturing, it is often necessary to provide a low-temperature environment for the vaccines being produced for a long time, which requires the support of a low-temperature chilled water system. For a considerable number of vaccine products, whether the low-temperature environment can be stably maintained determines the product quality of the vaccine. Therefore, at this stage, the industry generally turns on the low-temperature chilled water system for a long time, and the low-temperature chilled water system relies on a control system to automatically control the temperature of the chilled water to a constant value to stably maintain the low-temperature environment during the vaccine production process.

[0003] However, in the vaccine manufacturing process, the temperature requirement for the manufacturing process of a single vaccine is not necessarily constant; and a single tank usually changes the type of vaccine to be manufactured, which in turn causes the tank's demand for ambient temperature to change. This in turn causes the tank's cooling capacity to change frequently. At this time, when the low-temperature chilled water system using the above-mentioned low-temperature freezing control method is faced with the situation where the cooling capacity of the tank for manufacturing vaccines changes frequently, the overall energy efficiency is relatively low, and a good energy-saving and consumption-reducing effect cannot be achieved, which increases the cost of the vaccine manufacturing process. Utility Model Content

[0004] The utility model aims to provide an energy-saving and consumption-reducing device for a tank low-temperature storage chilled water system, which is used to reduce energy consumption when providing a stable low-temperature freezing environment for the tank.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A tank low-temperature storage chilled water system energy-saving and consumption-reducing device, comprising: a refrigerant temporary storage curved pipe, a first flow pipe, a second flow pipe, a first temperature sensor, a second temperature sensor, and a bidirectional drive water pump;

[0007] The refrigerant temporary storage curved pipe is arranged on the outer surface of the tank body. The refrigerant temporary storage curved pipe is provided with two ports, a first port and a second port. The first port is connected to the first flow pipe, and the second port is connected to the second flow pipe; the first temperature sensor is arranged at the first port, and the second temperature sensor is arranged at the second port; the bidirectional drive water pump is used to drive the bidirectional flow of the refrigerant in the refrigerant temporary storage curved pipe.

[0008] In a possible design, a bidirectional drive water pump is disposed in the middle section of the refrigerant temporary storage curved pipe.

[0009] In a possible design, the first flow conduit is also connected to the refrigerant outlet conduit of the tank low-temperature storage chilled water system, and the second flow conduit is also connected to the refrigerant inlet conduit of the tank low-temperature storage chilled water system.

[0010] In a possible design, the energy-saving and consumption-reducing device also includes a heat-insulating shell, which covers the surface of the refrigerant temporary storage curved pipe.

[0011] In a possible design, a first valve is provided on the first flow conduit.

[0012] In a possible design, a first valve is provided on the second flow conduit.

[0013] In a possible design, the energy-saving and consumption-reducing device further includes a control component, which is electrically connected to the first sensor, the second sensor, the bidirectional drive water pump, and the first valve. The control component is used to control the opening or closing of the first valve and the tank low-temperature storage chilled water system. The control component is also used to control the operating state of the bidirectional drive water pump.

[0014] In summary, the utility model has the following beneficial effects:

[0015] The utility model proposes an energy-saving and consumption-reducing device for a low-temperature storage chilled water system of a tank body, and the energy-saving and consumption-reducing device is connected to the original low-temperature storage chilled water system of the tank body. After the energy-saving and consumption-reducing device is set, when the low-temperature storage chilled water system is in operation, a part of the low-temperature chilled water in the refrigerant inlet pipe of the low-temperature storage chilled water system will enter the tank body, providing a low-temperature environment for vaccine manufacturing in the tank body, and the other part of the low-temperature chilled water will enter the refrigerant temporary storage curved pipe through the first flow pipe; when the low-temperature chilled water fills the refrigerant temporary storage curved pipe, the temperature detected by the second temperature sensor will meet the predetermined temperature, and the energy-saving and consumption-reducing device closes the first valve at this time; thereafter, when the cooling capacity of the tank body decreases, the low-temperature storage chilled water system stops running and the original chilled water circulation of the system stops, and the energy-saving and consumption-reducing device opens the first valve, and bidirectionally drives the water pump to operate so that the low-temperature chilled water in the curved pipe flows to the first flow pipe. The energy-saving and consumption-reducing device provides refrigeration for the tank, that is, the low-temperature chilled water temporarily stored in the refrigerant temporary storage curved pipe will enter the tank through the first flow pipe, and the high-temperature return water circulated in the tank will enter the refrigerant temporary storage curved pipe through the second flow pipe; when the low-temperature chilled water in the refrigerant temporary storage curved pipe is completely consumed, that is, when the high-temperature return water reaches the position of the first sensor, the temperature detected by the first temperature sensor will meet the predetermined temperature, and at this time, the bidirectional driving water pump operates to make the high-temperature return water in the curved pipe flow to the second flow pipe, so that it flows into the refrigerant outlet pipe of the low-temperature storage chilled water system, and the low-temperature storage chilled water system starts to operate again to refrigerate the tank and replenish the low-temperature chilled water for the refrigerant temporary storage curved pipe. In this way, when the cooling capacity of the tank is high, the low-temperature storage chilled water system can directly operate at high load to provide cooling, and simultaneously replenish the low-temperature chilled water in the refrigerant temporary storage curved pipe; when the cooling capacity of the tank is low, the low-temperature storage chilled water system is in a closed state, and the energy-saving and consumption-reducing device provides cooling. Therefore, the energy-saving and consumption-reducing device provided by the utility model can make the low-temperature storage chilled water system operate in a high-load state or a closed state. When the low-temperature storage chilled water system is closed, the energy-saving and consumption-reducing device provides a low-temperature environment for the tank body, while ensuring the stable low-temperature environment required for vaccine production in the tank body, the energy efficiency ratio of the low-temperature storage chilled water system is extremely high, which greatly reduces the energy consumption of the low-temperature storage chilled water system and saves electricity costs in the vaccine manufacturing process.

[0024] In the field of vaccine manufacturing, it is often necessary to provide a low-temperature environment for the vaccines being produced for a long time, which requires the support of a low-temperature chilled water system. For a considerable number of vaccine products, whether the low-temperature environment can be stably maintained determines the product quality of the vaccine. Therefore, at this stage, the industry generally turns on the low-temperature chilled water system for a long time, and the low-temperature chilled water system relies on a control system to automatically control the temperature of the chilled water to a constant value to stably maintain the low-temperature environment during the vaccine production process.

[0025] However, the low-temperature chilled water system using the above-mentioned low-temperature freezing control method has a relatively low overall energy efficiency when faced with the situation where the amount of cold used in vaccine manufacturing changes frequently and greatly, and cannot achieve good energy-saving and consumption-reducing effects, thereby increasing the cost in the vaccine manufacturing process.

[0026] Therefore, in order to solve the above problems existing in the industry, the utility model proposes an energy-saving and consumption-reducing device for a tank low-temperature storage chilled water system, which can improve energy efficiency and reduce energy consumption while providing a stable low-temperature freezing environment for the tank.

[0027] The utility model provides an energy-saving and consumption-reducing device for a tank body low-temperature storage chilled water system. The energy-saving and consumption-reducing device for a tank body low-temperature storage chilled water system comprises: a refrigerant temporary storage curved pipe 1, a first flow pipe 2, a second flow pipe 3, a first temperature sensor 4, a second temperature sensor 5, a bidirectional drive water pump 6, and a first valve 7.

[0028] It is understandable that the refrigerant in the refrigerant temporary storage curved pipe 1 can be water or other types of refrigerant, and the utility model does not make specific limitations. In the following description, for ease of understanding, the type of refrigerant is introduced as water.

[0029] It should be noted that the energy-saving and consumption-reducing device for the tank low-temperature storage chilled water system provided by the utility model is used in conjunction with the low-temperature storage chilled water system, that is, the energy-saving and consumption-reducing device is connected to the low-temperature storage chilled water system to jointly achieve the technical effect of the utility model.

[0030] In one example, Figure 1 As shown, the utility model provides a tank low temperature storage chilled water system energy saving and consumption reduction device, which is arranged in conjunction with the tank low temperature storage chilled water system. The low temperature storage chilled water system specifically includes: a refrigeration host 8, a refrigerant inlet pipe 9, and a refrigerant outlet pipe 10. The structure and operating principle of the tank low temperature storage chilled water system energy saving and consumption reduction device are introduced below:

[0031] refer to Figure 1 In the energy-saving and consumption-reducing device for the tank low-temperature storage chilled water system, the refrigerant temporary storage curved pipe 1 is arranged on the outer surface of the tank 20, and the refrigerant temporary storage curved pipe 1 is provided with a first port 101 and a second port 102, a total of two ports.

[0032] The first port 101 is connected to the first flow pipe 2 , and the second port 102 is connected to the second flow pipe 3 .

[0033] The first temperature sensor 4 is disposed at the first port 101 , and the second temperature sensor 5 is disposed at the second port 102 .

[0034] The first flow pipe 2 is also connected to the refrigerant outlet pipe 10 of the tank low-temperature storage chilled water system, and the second flow pipe 3 is also connected to the refrigerant inlet pipe 9 of the tank low-temperature storage chilled water system.

[0035] Optionally, the bidirectional driving water pump 6 is arranged in the middle section of the refrigerant temporary storage curved pipe 1 to drive the refrigerant in the refrigerant temporary storage curved pipe 1 to flow in both directions.

[0036] Optionally, a first valve 7 is provided on the first flow conduit 2 ; or, a first valve 7 is provided on the second flow conduit 3 .

[0037] Combined with the above content and the specific cooling capacity in the tank, the operation of the energy-saving and consumption-reducing device for the low-temperature storage chilled water system of the tank is introduced below:

[0038] (1) The cooling demand inside the tank is high.

[0039] At this time, the low-temperature storage chilled water system is started and the low-temperature chilled water generated by the refrigeration main unit 8 flows into the cold pipe in the tank body 20 through the refrigerant inlet pipe 9, and the other part flows into the first flow pipe 2. The low-temperature chilled water flowing into the cold pipe in the tank body 20 provides a stable low-temperature environment for vaccine manufacturing in the tank body.

[0040] The low-temperature chilled water flowing into the first flow pipe 2 will enter the refrigerant temporary storage curved pipe 1. When the low-temperature chilled water fills the refrigerant temporary storage curved pipe 1, the temperature detected by the second temperature sensor 5 will meet the predetermined temperature, and the energy-saving and consumption-reducing device will close the first valve 7.

[0041] That is to say, when the cooling capacity in the tank is high, the low-temperature storage chilled water system is in a high-load operation state. While providing cooling capacity for the tank, it will also fill the energy-saving and consumption-reducing device with low-temperature chilled water. The low-temperature chilled water is temporarily stored in the refrigerant temporary storage curved pipe.

[0042] It is understandable that in the field of this technology, the cooling capacity of the low-temperature storage chilled water system under high load is usually higher than the cooling capacity of the tank body. This is because in order to ensure the cooling capacity demand in the vaccine manufacturing process, during the design phase of the low-temperature storage chilled water system, the cooling capacity of the system is generally configured according to the maximum load that may be required in the vaccine manufacturing process, that is, the cooling capacity of the low-temperature storage chilled water system generally exceeds the cooling capacity demand of vaccine manufacturing by a part. Therefore, while the low-temperature storage chilled water system provides cooling capacity for the tank body 20, it injects low-temperature chilled water into the refrigerant temporary storage curved pipe 1. This does not exceed the cooling capacity of the low-temperature storage chilled water system. It merely utilizes the excess cooling capacity of the low-temperature storage chilled water system, and does not generate additional energy consumption compared to the original system. Provide a stable low-temperature environment for vaccine manufacturing

[0043] (2) The cooling capacity inside the tank is low.

[0044] At this time, the low-temperature storage chilled water system stops running, that is, the chilled water circulation of the original low-temperature storage chilled water system stops.

[0045] The energy-saving and consumption-reducing device opens the first valve 7, and bidirectionally drives the water pump 6 to operate so that the low-temperature chilled water in the refrigerant temporary storage curved pipe 1 flows to the first flow pipe 2. In other words, the energy-saving and consumption-reducing device provides refrigeration for the tank body 20. At this time, the low-temperature chilled water temporarily stored in the refrigerant temporary storage curved pipe 1 will enter the tank body 20 through the first flow pipe 2, and the high-temperature return water circulated out of the tank body will enter the refrigerant temporary storage curved pipe 1 through the second flow pipe 3.

[0046] When the low-temperature chilled water in the refrigerant temporary storage curved pipe 1 is completely consumed, it is not difficult to understand that the high-temperature return water at this time will reach the position of the first sensor 4, and the temperature detected by the first temperature sensor 4 will meet the predetermined temperature. Then, the bidirectional drive water pump 6 operates to make the high-temperature return water in the refrigerant temporary storage curved pipe 1 flow to the second flow pipe 3, and at the same time, the low-temperature storage chilled water system starts to operate again to refrigerate the tank 20 and replenish the low-temperature chilled water for the refrigerant temporary storage curved pipe 1.

[0047] Based on the above description of the operating principle of the energy-saving and consumption-reducing device for the low-temperature storage chilled water system of the tank, it is not difficult to see that in the utility model, when the cold demand of the tank is high, the low-temperature storage chilled water system can directly operate at high load to provide cooling, and simultaneously replenish the low-temperature chilled water in the refrigerant temporary storage curved pipe; when the cold demand of the tank is low, the low-temperature storage chilled water system is in a closed state, and the energy-saving and consumption-reducing device provides refrigeration. Regardless of whether the cold demand of the tank is high or low, due to the existence of the energy-saving and consumption-reducing device, the low-temperature storage chilled water system will only be in a high-load operation state or a closed state, which greatly improves the energy efficiency ratio of the low-temperature storage chilled water system, reduces the energy consumption of the low-temperature storage chilled water system as a whole, and saves electricity costs in the vaccine manufacturing process.

[0048] Based on the above technical solution, the utility model provides an energy-saving and consumption-reducing device for a low-temperature storage chilled water system of a tank, which is connected to the original low-temperature storage chilled water system of the tank. After the energy-saving and consumption-reducing device is set, when the low-temperature storage chilled water system is in operation, a part of the low-temperature chilled water in the refrigerant inlet pipe of the low-temperature storage chilled water system will enter the tank, providing a low-temperature environment for vaccine manufacturing in the tank, and another part of the low-temperature chilled water will enter the refrigerant temporary storage curved pipe through the first flow pipe; when the low-temperature chilled water fills the refrigerant temporary storage curved pipe, the temperature detected by the second temperature sensor will meet the predetermined temperature, and the energy-saving and consumption-reducing device closes the first valve at this time; thereafter, when the cooling capacity of the tank decreases, the low-temperature storage chilled water system stops running and the original chilled water circulation of the system stops, and the energy-saving and consumption-reducing device opens the first valve, and bidirectionally drives the water pump to operate so that the low-temperature chilled water in the curved pipe flows to the first flow pipe. The energy-saving and consumption-reducing device provides refrigeration for the tank, that is, the low-temperature chilled water temporarily stored in the refrigerant temporary storage curved pipe will enter the tank through the first flow pipe, and the high-temperature return water circulated in the tank will enter the refrigerant temporary storage curved pipe through the second flow pipe; when the low-temperature chilled water in the refrigerant temporary storage curved pipe is completely consumed, that is, when the high-temperature return water reaches the position of the first sensor, the temperature detected by the first temperature sensor will meet the predetermined temperature, and at this time, the bidirectional driving water pump operates to make the high-temperature return water in the curved pipe flow to the second flow pipe, so that it flows into the refrigerant outlet pipe of the low-temperature storage chilled water system, and the low-temperature storage chilled water system starts to operate again to refrigerate the tank and replenish the low-temperature chilled water for the refrigerant temporary storage curved pipe. In this way, when the cooling capacity of the tank is high, the low-temperature storage chilled water system can directly operate at high load to provide cooling, and simultaneously replenish the low-temperature chilled water in the refrigerant temporary storage curved pipe; when the cooling capacity of the tank is low, the low-temperature storage chilled water system is in a closed state, and the energy-saving and consumption-reducing device provides cooling. Therefore, the energy-saving and consumption-reducing device provided by the utility model can make the low-temperature storage chilled water system operate in a high-load state or a closed state. When the low-temperature storage chilled water system is closed, the energy-saving and consumption-reducing device provides a low-temperature environment for the tank body, while ensuring the stable low-temperature environment required for vaccine production in the tank body, the energy efficiency ratio of the low-temperature storage chilled water system is extremely high, which greatly reduces the energy consumption of the low-temperature storage chilled water system and saves electricity costs in the vaccine manufacturing process.

[0049] In another example, Figure 2 As shown, the energy-saving and consumption-reducing device for a tank low-temperature storage chilled water system provided by the utility model also includes a heat-insulating shell 11.

[0050] The heat-insulating housing 11 can effectively prevent the temperature of the low-temperature chilled water in the refrigerant temporary storage curved pipe 1 from being affected by the external environment, thereby preventing the cooling capacity of the energy-saving and consumption-reducing device from being affected.

[0051] In another example, Figure 3 As shown, the energy-saving and consumption-reducing device for a tank low-temperature storage chilled water system provided by the utility model also includes a control component 12.

[0052] The control component 12 is electrically connected to the first sensor 2 , the second sensor 3 , the bidirectional drive water pump 6 , and the first valve 7 .

[0053] Optionally, the control component 12 is used to control the opening or closing of the first valve 7 and the tank low-temperature storage chilled water system, and is also used to control the operating state of the two-way drive valve 6.

[0054] For example, the control component 12 can be implemented as a single-chip microcomputer, or a chip, or other control modules provided with integrated circuits in actual applications, and the present invention does not make any specific limitation.

[0055] It should be pointed out that Figure 1 , Figure 2 , Figure 3 The composition structure shown in the figure does not constitute a limitation on a tank low temperature storage chilled water system energy saving and consumption reduction device, except Figure 1 , Figure 2 , Figure 3 In addition to the components shown, a tank low-temperature storage chilled water system energy saving and consumption reduction device may include more or fewer components than shown in the figure, or a combination of certain components, or a different arrangement of components.
