Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
In the related art, in order to realize the cooling function, a plurality of cooling towers are often used in parallel in the cooling system. However, when a plurality of cooling towers are used in parallel, on one hand, due to the difference of pipeline resistances, under the condition that the valve openings are the same, the water distribution amount of each cooling tower is different, so that uniform water distribution is difficult to realize, the water outlet temperature of each cooling tower is inconsistent, the heat of the system is difficult to balance, and the stability of the system is influenced. On the other hand, as the service life increases, the heat dissipation capability of the cooling tower itself is attenuated, and even if the cooling tower has the same heat dissipation capability, the heat dissipation capability may be attenuated to different degrees, so that the heat dissipation capability of each cooling tower is not uniform. On the other hand, when the building space is limited, the cooling tower disposed closer to the wall may have a weaker heat dissipation capability, so that the heat dissipation capability of each cooling tower may be uneven. The above reasons will cause the difference of the outlet water temperature of each cooling tower, the heat imbalance of the cooling system and the influence on the stability of the system operation.
Based on the above, the embodiment of the invention provides a cooling system and a temperature control method, a temperature control device and equipment thereof.
The first embodiment is as follows:
in order to solve at least the technical problems set forth in the present invention, embodiments of the present invention provide a cooling system.
The cooling system provided by the embodiment of the invention can comprise: a control assembly and at least two cooling devices; each cooling device is connected in parallel; a temperature detection assembly is arranged at the water outlet of each cooling device, and each temperature detection assembly is connected with a control assembly; the temperature detection assembly is used for detecting the outlet water temperature value of the cooling device; the water inlet of each cooling device is provided with an opening-adjustable regulating valve, and each regulating valve is connected with a control assembly; and the control assembly is used for acquiring the water outlet temperature value of each cooling device, and sending an opening adjusting instruction to the corresponding adjusting valve according to the water outlet temperature value of each cooling device and a preset water outlet temperature threshold value so as to adjust the opening of the adjusting valve.
In some embodiments, the cooling device may be a cooling tower, and the opening-adjustable regulating valve may be a proportional-integral regulating valve. It should be noted that, in the present embodiment, the cooling device and the opening-adjustable regulating valve are merely listed, and are not limited.
Fig. 1 is a schematic structural diagram of a cooling system according to an embodiment of the present invention, and referring to fig. 1, in this embodiment, the number of cooling towers may be 4, which refers to reference numerals 1, 2, 3, and 4 in fig. 1, where the number of cooling towers is merely an example, and the cooling towers are connected in parallel.
In some embodiments, optionally, the water outlet of the cooling device is connected with a water outlet pipe; and/or the water inlet part of the cooling device is connected with a water inlet pipe.
The cooling tower 1 will be described as an example. Referring to fig. 1, the temperature detection assembly 9 may be disposed at the water outlet pipe of the cooling tower 1, and the proportional-integral regulating valve 5 is disposed at the water inlet pipe. Every cooling tower structure is the same, and like the same, cooling tower 2, cooling tower 3 and cooling tower 4 correspond temperature-detecting element 10, temperature-detecting element 11, temperature-detecting element 12 respectively, and proportional-integral governing valve 6, proportional-integral governing valve 7, proportional-integral governing valve 8. Wherein, temperature detect subassembly 10, temperature detect subassembly 11, temperature detect subassembly 12, proportional-integral governing valve 6, proportional-integral governing valve 7, proportional-integral governing valve 8 set up respectively in the outlet pipe and the inlet tube department of cooling tower 2, cooling tower 3, cooling tower 4, and the setting rule refers to cooling tower 1, and this time does not do not specifically describe. The temperature detection assembly 10, the temperature detection assembly 11 and the temperature detection assembly 12 are the same; the proportional integral regulating valve 6, the proportional integral regulating valve 7, and the proportional integral regulating valve 8 are the same.
Wherein, the temperature detection component can be a temperature sensor. The control assembly can be arranged in a control cabinet of the cooling tower, the number of the control assemblies can be one, and one control assembly can also be arranged on each cooling tower.
In the cooling process, the control component acquires the outlet water temperature value of each cooling device through the temperature detection component, and the opening degree of each proportional-integral regulating valve is regulated by comparing each outlet water temperature value with a preset outlet water temperature threshold value.
In some embodiments, optionally, the control module is configured to obtain the outlet water temperature value of each cooling device at intervals of a preset time.
For example, the control module may monitor the effluent temperature value once every 30 minutes, and it should be noted that, in the present embodiment, the 30 minutes is an example and is not limited.
According to the cooling system provided by the embodiment of the invention, the temperature detection assembly is arranged at the water outlet of each cooling device of the cooling system, and the regulating valve with adjustable opening degree is arranged at the water inlet of each cooling device, so that an opening degree regulating instruction is sent to the corresponding regulating valve according to the water inlet temperature value and the preset water outlet temperature threshold value of each cooling device to regulate the opening degree of the regulating valve and regulate the water inlet amount of each cooling device, the heat dissipation capacity of each cooling device is regulated, the water outlet temperature of each cooling device is consistent, the heat of the cooling system is balanced, and the stability of the system is ensured.
In some embodiments, optionally, the control component is configured to calculate a difference between each effluent temperature value and a preset effluent temperature threshold; judging whether each difference value is within a preset difference value range or not; and if any difference value is not within the preset difference value range, sending an opening degree adjusting instruction to the corresponding adjusting valve so as to adjust the opening degree of the adjusting valve.
In some embodiments, optionally, the control component is further configured to: and receiving a preset difference range setting instruction, and updating the preset difference range according to the preset difference range setting instruction.
For example, in this embodiment, the obtained outlet water temperature values of the 4 cooling towers may be 30.5 ℃, 30.0 ℃, 29 ℃ and 28.5 ℃ in sequence.
In this embodiment, the preset outlet water temperature threshold may be set to 30 ℃, the preset difference range is set to [ -1 ℃,1 ℃), and the user may change the preset difference range according to the requirement.
After the outlet water temperature value of each cooling device is obtained, the difference value between each outlet water temperature value and the preset outlet water temperature threshold value can be calculated, namely 4 difference values are sequentially calculated to be 0.5 ℃, 0 ℃,1 ℃ and 1.5 ℃, wherein the 0.5 ℃, 0 ℃ and 1 ℃ are all within-1 ℃,1 ℃ and-1.5 ℃ but not within-1 ℃ and 1 ℃. Therefore, an opening degree adjustment instruction is sent to the adjustment valve corresponding to the cooling tower 4 corresponding to the difference value of-1.5 ℃ to adjust the opening degree of the adjustment valve 8.
In some embodiments, optionally, the control component is configured to send an opening increasing adjustment instruction to the adjusting valve corresponding to the difference value that is not within the preset difference value range to increase the opening of the adjusting valve when any difference value is not within the preset difference value range and the effluent temperature value corresponding to the difference value that is not within the preset difference value range is lower than the preset effluent temperature threshold value.
For example, when it is determined that the difference value-1.5 ℃ is not within the preset difference value range [ -1 ℃,1 ℃ ] and the outlet water temperature value of the cooling tower 4 is 28.5 ℃ lower than the preset outlet water temperature threshold value of 30 ℃, it indicates that the heat dissipation capacity of the cooling tower 4 is surplus, and sends an opening increasing adjustment instruction to the proportional-integral regulating valve 8 of the cooling tower 4, so as to increase the opening of the proportional-integral regulating valve 8 and increase the water inflow of the cooling tower 4, so that the difference value between the outlet water temperature of the cooling tower 4 and the preset outlet water temperature threshold value is within the preset difference value range, and the heat balance of the system is realized.
In some embodiments, optionally, the control component is configured to send an opening degree reduction adjustment instruction to the adjusting valve corresponding to the difference value that is not within the preset difference value range to reduce the opening degree of the adjusting valve when any difference value is not within the preset difference value range and the effluent temperature value corresponding to the difference value that is not within the preset difference value range is higher than the preset effluent temperature threshold value.
Similarly, if the difference value of 1.5 ℃ is determined not to be within the preset difference value range of (-1 ℃), 1 ℃) and the corresponding outlet water temperature value of the cooling tower is 31.5 ℃ higher than the preset outlet water temperature threshold value of 30 ℃, the insufficient heat dissipation capacity of the cooling tower is indicated, an opening degree reducing adjustment instruction is sent to the proportional-integral regulating valve of the cooling tower, so that the opening degree of the proportional-integral regulating valve is reduced, the water inflow of the cooling tower is reduced, the difference value of the outlet water temperature of the cooling tower and the preset outlet water temperature threshold value is within the preset difference value range, and the heat balance of the system is realized.
