Description

Technical Field

[0001] The present invention relates to the field of electrical equipment technology, and in particular to an exhaust water replenishment control method and a control device for a water cooling unit. Background Art

[0002] In the related technology, due to the widespread application of large-scale water-cooled units, the water filling amount of the chilled water pipeline and the exhaust of the pipeline are particularly important for the normal operation of the entire system (including terminal coils, water-cooled units and other equipment). If the water filling amount is insufficient, air is easily introduced into the entire system. When air enters the system's cold water pipeline, for the refrigeration coil, the water flow in the refrigeration coil is abnormal, and the refrigeration effect of the coil deteriorates; for the water-cooled unit, the water flow of the water pump will decrease after the gas is sucked in, which will cause the chilled water to not flow normally, and then cause the refrigeration effect of the system to deteriorate.

DETAILED DESCRIPTION

[0049] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] The exhaust water replenishment control method, control device and water cooling unit of the water cooling unit proposed in the present invention are described below with reference to the accompanying drawings. Among them, before the embodiment of the present invention is described in detail, the entire application scenario is first described. The exhaust water replenishment control method, control device, electronic device and computer-readable storage medium of the water cooling unit of the embodiment of the present invention can be applied to the water cooling unit locally, and can also be applied to the cloud platform in the Internet field, or other types of cloud platforms in the Internet field, or can also be applied to third-party devices. Among them, the third-party device may include many different types such as mobile phones, tablet computers, notebooks, car computers and other smart terminals.

[0051] The following is an explanation of the exhaust water replenishment method applicable to a water-cooled unit. It should be understood that the control method of the embodiment of the present invention can also be applied to a cloud platform and third-party equipment.

[0052] It should be pointed out that before introducing the exhaust water replenishment control method of the present invention, the structural basis of the water cooling unit on which the method is based is first described, wherein Figure 4 As shown, the water cooling unit includes a cold water pipe 1, a refrigeration coil and a fan. The cold water pipe 1 transports cold water to the refrigeration coil, and the fan blows air outward to blow the cold water in the refrigeration coil to the area to be refrigerated. The cold water pipe 1 is provided with a water pump 2, a water replenishment valve 11 and an exhaust valve 12. The water replenishment valve 11 is connected to the water replenishment device 10 through a water replenishment pipeline to replenish water into the cold water pipe 1, and a water replenishment pump 2 is also provided on the water replenishment pipeline. The exhaust valve 12 is usually arranged at the highest point of the cold water pipe 1 to discharge the gas in the cold water pipe 1.

[0053] like Figure 1 and2 As shown, the exhaust water replenishment control method of the water-cooling unit according to the first embodiment of the present invention includes:

[0054] Step S1, obtaining first water flow information in the cold water pipe 1;

[0055] Step S2, controlling and adjusting the opening of the exhaust valve 12 according to the first water flow information;

[0056] Step S3, when the exhaust valve 12 is open, obtain the pipeline pressure and / or the second water flow information in the cold water pipeline 1, and when the pipeline pressure and / or the second water flow information meet the set conditions, close the exhaust valve 12 and open the water replenishment valve 11 to replenish water.

[0057] According to the exhaust and water replenishment control method of the water-cooled unit according to an embodiment of the present invention, the specific working process is as follows: first, after the water-cooled unit is started and the water pump 2 is running, the first water flow information in the cold water pipe 1 is obtained, wherein the first water flow information refers to the specific parameter information of the cold water flow in the cold water pipe 1 when the exhaust valve 12 is closed. The first water flow information may include parameters such as the maximum flow value, the minimum flow value and the flow change value of the cold water pipe 1 within a certain period of time, and the present invention does not make any special limitations here.

[0058] After obtaining the first water flow information, the controller 9 will analyze the first water flow information, thereby determining the gas condition in the cold water pipe 1 based on the first water flow information, and further adjust the opening of the exhaust valve 12 according to the gas condition in the cold water pipe 1, thereby achieving the purpose of discharging excess gas when there is excess gas in the cold water pipe 1, ensuring the stability of the water flow and pipeline pressure in the cold water pipe 1, and ensuring the normal flow of chilled water.

[0059] Specifically, the controller 9 can obtain the change of water flow within a certain period of time through the first water flow information. If it is detected that the value of the water flow within a certain period of time is unstable, for example, the water flow fluctuates within a certain period of time, or the change amplitude of the water flow is too large, then it can be judged that there is excess gas in the current cold water pipe 1, which causes the water flow in the cold water pipe 1 to be blocked. At this time, the controller 9 will open the exhaust valve 12 to discharge the excess gas in the cold water pipe 1 to the outside of the cold water pipe 1 to ensure the smooth flow of water.

[0060] Furthermore, during the process of opening the exhaust valve 12, the controller 9 will continuously monitor the flow or pressure conditions in the cold water pipe 1, that is, the controller 9 obtains the pipe pressure and / or the second water flow information in the cold water pipe 1, wherein the second water flow information refers to the specific parameter information of the cold water flow in the cold water pipe 1 when the exhaust valve 12 is opened. The second water flow information may include parameters such as the maximum flow value, minimum flow value and flow change value of the cold water pipe 1 within a certain period of time, and the present invention does not make any special limitations here.

[0061] After obtaining the above-mentioned pipeline pressure and / or the second water flow information, the controller 9 will further analyze it. When it is determined that the pipeline pressure and / or the second water flow information meets the set conditions, it proves that the excess gas in the cold water pipe 1 has been discharged. At this time, in order to avoid unnecessary loss of chilled water in the cold water pipe 1, the controller 9 will close the exhaust valve 12. Moreover, after closing the exhaust valve 12, the controller 9 will further open the water replenishment valve 11 to replenish water to the cold water pipe 1, thereby replenishing the cavity caused by the discharge of excess gas in the cold water pipe 1, and replenishing the chilled water in the cold water pipe 1 that is mistakenly discharged due to exhaust, thereby ensuring sufficient water in the cold water pipe 1, thereby improving the refrigeration effect of the water cooling unit.

[0062] In the related art, due to the widespread application of large-scale water-cooled units, the water filling amount of the chilled water pipeline and the exhaust of the pipeline are particularly important for the normal operation of the entire system (including the terminal coil, water-cooled unit and other equipment). If the water filling amount is insufficient, air is easily introduced into the entire system. When air enters the system's cold water pipeline, for the refrigeration coil, the water flow in the refrigeration coil is abnormal, and the refrigeration effect of the coil deteriorates; for the water-cooled unit, the water flow of the water pump 2 will decrease after the gas is sucked in, which will cause the chilled water to not flow normally, and then cause the refrigeration effect of the system to deteriorate.

[0063] The existing methods and devices for replenishing water in pipelines and methods and devices for discharging gas in pipelines are not linked to each other, but work independently. As a result, it is difficult to fully discharge the gas in the water pipeline and stably control the pressure in the water pipeline, which increases the instability of the system and cannot ensure the refrigeration effect of the system.

[0064] In summary, in order to solve the technical defects existing in the above-mentioned related technologies, the present invention provides a method for controlling exhaust and water replenishment of a water-cooled unit. The method controls the action of the exhaust valve 12 and the action of the water replenishment valve 11 by monitoring the water flow and the pipeline pressure in the cold water pipe 1, so as to replenish an appropriate amount of water in time after the exhaust in the cold water pipe 1 is completed. In this way, on the one hand, the excess gas in the cold water pipe 1 is discharged to the outside of the cold water pipe 1 to ensure the smooth flow of water; on the other hand, the cavity generated by the discharge of excess gas in the cold water pipe 1 is replenished, and the chilled water mistakenly discharged due to exhaust in the cold water pipe 1 is replenished to ensure the sufficiency of the water volume in the cold water pipe 1, thereby improving the refrigeration effect of the water-cooled unit. Therefore, the method of the present invention simultaneously realizes the sufficient discharge of the gas in the cold water pipe 1 and the stable control of the pressure in the cold water pipe 1.

[0065] According to some embodiments of the present invention, the first water flow information includes: when the exhaust valve 12 is closed, the flow difference between the maximum water flow and the minimum water flow detected in the cold water pipe 1 within the first monitoring time period.

[0066] like Figure 2 As shown, further, the step of controlling and adjusting the opening of the exhaust valve 12 according to the water flow information specifically includes:

[0067] Determine that the flow difference between the maximum water flow rate and the minimum water flow rate is greater than the set flow difference, then control the exhaust valve 12 to open at the first exhaust opening;

[0068] Alternatively, if it is determined that the flow difference between the maximum water flow and the minimum water flow is less than or equal to the set flow difference, the maximum water flow is further compared with the set exhaust flow, and the exhaust valve 12 is controlled to open at the second exhaust opening when the maximum water flow is less than the set exhaust flow.

[0069] In the above embodiment, the flow difference between the maximum water flow and the minimum water flow can reflect the change of the water flow in the cold water pipe 1. When the flow difference is too large, for example, the flow difference is greater than the set flow difference, it proves that the water flow in the cold water pipe 1 changes abnormally. At this time, the reason for the abnormal change in water flow is that more excess gas has entered the cold water pipe 1. Therefore, in the above situation, the controller 9 needs to open the exhaust valve 12 for exhaust.

[0070] When the flow difference is small, for example, the flow difference is less than the set flow difference, it proves that the water flow change in the cold water pipe 1 is normal, but at this time there is still a risk of excess gas in the cold water pipe 1, that is, due to the large amount of excess gas, a large air resistance is generated, which is reflected in the water flow rate as the water flow rate continues to remain at a low level. Therefore, the maximum water flow rate will be further compared with the set exhaust flow rate. When the maximum water flow rate is less than the set exhaust flow rate, it indicates that the air resistance in the pipeline is too large, causing the water flow rate to continue to remain at a low level. Therefore, when the above conditions are met, the controller 9 will directly open the exhaust valve 12.

[0071] It can be understood that when the flow difference is less than the set flow difference and the maximum water flow is greater than the set exhaust flow, it proves that the water flow in the cold water pipe 1 is in a normal state, that is, there is no excess gas in the cold water pipe 1, or the excess gas in the cold water pipe 1 is small and it will not produce adverse effects.

[0072] In one embodiment of the present invention, the first exhaust opening is obtained as follows:

[0073] The size of the first exhaust opening is determined according to the interval range of the flow difference between the maximum water flow and the minimum water flow, wherein the flow difference is positively correlated with the first exhaust opening.

[0074] It can be understood that when the flow difference is larger, it proves that the change amplitude of the water flow in the cold water pipe 1 is larger, that is, there is more excess gas in the cold water pipe 1. At this time, in order to discharge the excess gas as soon as possible, the controller 9 will increase the exhaust opening of the exhaust valve 12.

[0075] In another embodiment of the present invention, the second exhaust opening is obtained as follows:

[0076] The size of the second exhaust opening is determined according to the interval range where the maximum water flow rate is located, wherein the maximum water flow rate is negatively correlated with the second exhaust opening.

[0077] It can be understood that when the maximum water flow rate is smaller, the water resistance in the cold water pipe 1 is greater, that is, there is more excess gas in the cold water pipe 1. At this time, in order to discharge the excess gas as quickly as possible, the controller 9 will increase the exhaust opening of the exhaust valve 12.

[0078] According to some embodiments of the present invention, when the pipeline pressure and / or the second water flow information meets the set conditions, the exhaust valve 12 is closed and the water supply valve 11 is opened for water supply, and the set conditions are:

[0079] The pipeline pressure is reduced to reach or be lower than the set pressure;

[0080] Alternatively, the water flow in the cold water pipe 1 continues to decrease during the second monitoring time period;

[0081] Alternatively, the pipeline pressure decreases to reach or be less than the set pressure and the water flow in the cold water pipeline 1 continues to decrease within the second monitoring time period.

[0082] In this embodiment, the exhaust valve 12 will continuously exhaust the gas in the cold water pipe 1 during the opening process. During the above process, the pipeline pressure in the cold water pipe 1 will continue to decrease. It can be understood that when the pipeline pressure is reduced to a constant value, the gas in the pipeline is basically all discharged, that is, when it is detected that the pipeline pressure is reduced to or less than the set pressure, it proves that the exhaust process is over; or, when the cold water pipe 1 has exhausted all the gas, the chilled water will continue to be discharged along the exhaust valve 12. At this time, the water flow in the cold water pipe 1 will gradually decrease. Therefore, when it is detected that the water flow in the cold water pipe 1 continues to decrease during the second monitoring period, it proves that the exhaust process is over.

[0083] Therefore, as long as at least one of the above-mentioned pipeline pressure and water flow conditions is met, it can be proved that the exhaust is completed. After that, the controller 9 can close the exhaust valve 12 and open the water replenishment valve 11 to carry out the next stage of water replenishment work on the cold water pipeline 1.

[0084] According to some embodiments of the present invention, the step of opening the water supply valve 11 to supply water specifically includes:

[0085] Determine that the exhaust valve 12 is closed, and obtain the water flow rate before water replenishment and / or the pipeline pressure before water replenishment of the cold water pipeline 1 when the exhaust valve 12 is closed;

[0086] Determine the set water replenishment opening when the water replenishment valve 11 is opened according to the water flow before water replenishment and / or the pipeline pressure before water replenishment;

[0087] The water supply valve 11 is controlled to open at a set water supply opening.

[0088] In this way, before water replenishment, since the pipeline pressure and water flow rate of the cold water pipeline 1 decrease during the exhaust process, in order to achieve precise control of the water replenishment process, the controller 9 needs to obtain the water flow rate and / or the pipeline pressure before water replenishment of the cold water pipeline 1 when the exhaust valve 12 is closed, and then compare the water flow rate and / or the pipeline pressure before water replenishment with the water flow rate and / or the pipeline pressure in the initial state, and adjust the opening degree of the water replenishment valve 11 according to the comparison result, so as to achieve precise control of the water replenishment process and ensure the stability of the chilled water amount in the unit after water replenishment.

[0089] Further, the step of determining the set water replenishment opening degree when the water replenishment valve 11 is opened according to the water flow before water replenishment and / or the pipeline pressure before water replenishment specifically includes:

[0090] According to the water flow before water replenishment being in the first flow range or the pipeline pressure before water replenishment being in the first pressure range, determining to set the water replenishment opening degree to the first water replenishment opening degree;

[0091] According to the water flow before water replenishment being in the second flow range or the pipeline pressure before water replenishment being in the second pressure range, determining to set the water replenishment opening degree to the second water replenishment opening degree;

[0092] According to the water flow before water replenishment being in the third flow range or the pipeline pressure before water replenishment being in the third pressure range, it is determined to set the water replenishment opening degree as the maximum opening degree of the water replenishment valve 11 .

[0093] Among them, the first flow range is greater than the second flow range and the second flow range is greater than the third flow range, the first pressure range is greater than the second pressure range and the second pressure range is greater than the third pressure range, the first water replenishment opening is less than the second water replenishment opening and the second water replenishment opening is less than the maximum opening.

[0094] According to some embodiments of the present invention, after the step of opening the water replenishment valve 11 to replenish water, the exhaust water replenishment control method of the water-cooling unit further includes:

[0095] Obtain the pipeline pressure of the cold water pipeline 1 during water replenishment after the water replenishment valve 11 is opened;

[0096] When the pipeline pressure reaches the set water replenishment pressure during water replenishment, the water replenishment valve 11 is controlled to close.

[0097] In this way, when the pipeline pressure reaches the set water replenishment pressure during water replenishment, it proves that the water volume in the unit has reached the initial level after water replenishment. At this time, the water replenishment process ends, and the controller 9 controls the water replenishment valve 11 to close.

[0098] According to some other embodiments of the present invention, after the step of opening the water replenishment valve 11 to replenish water, the exhaust water replenishment control method of the water-cooling unit further includes:

[0099] Obtain the water flow rate of the cold water pipe 1 during water replenishment after the water replenishment valve 11 is opened;

[0100] When the water flow rate during water replenishment reaches the set water replenishment flow rate, the water replenishment valve 11 is controlled to close.

[0101] In this way, when the water flow rate during water replenishment reaches the set water replenishment flow rate, it proves that the water volume in the unit has reached the initial level after water replenishment. At this time, the water replenishment process ends, and the controller 9 controls the water replenishment valve 11 to close.

[0102] The exhaust water replenishment control device of the water-cooling unit provided by the present invention is described below. The exhaust water replenishment control device of the water-cooling unit described below and the exhaust water replenishment control method of the water-cooling unit described above can be referred to each other.

[0103] like Figure 3As shown, according to the exhaust and water replenishment control device of the water-cooling unit of the second embodiment of the present invention, the water-cooling unit includes a cold water pipe 1 and a water pump 2, an exhaust valve 12 and a water replenishment valve 11 arranged on the cold water pipe 1, and the control device includes:

[0105] A first control module 120, configured to control and adjust the opening of the exhaust valve 12 according to the first water flow information;

[0106] The second control module 130 is used to obtain the pipeline pressure and / or the second water flow information in the cold water pipeline 1 when the exhaust valve 12 is opened, and close the exhaust valve 12 and open the water replenishment valve 11 for water replenishment when the pipeline pressure and / or the second water flow information meet the set conditions.

[0107] According to the water-cooling unit of the third aspect embodiment of the present invention, it includes a cold water pipe 1, a refrigeration coil and a fan. The cold water pipe 1 transports cold water to the refrigeration coil, and the fan blows air outward to blow the cold water in the refrigeration coil to the area to be refrigerated. The cold water pipe 1 is provided with a water pump 2, a water replenishment valve 11 and an exhaust valve 12. The water replenishment valve 11 is connected to the water replenishment device 10 through a water replenishment pipeline to replenish water into the cold water pipe 1, and a water replenishment pump 2 is also provided on the water replenishment pipeline. The exhaust valve 12 is usually arranged at the highest point of the cold water pipe 1 to discharge the gas in the cold water pipe 1.
