The technical solution of the present disclosure provides a heat dissipation control method and apparatus based on a cooling tower, a device, a medium, and a product. Through collecting the target heat dissipation information of the cooling tower, whether to select the dry-cooling heat dissipation mode or wet-cooling heat dissipation mode, or the joint operation of the dry-cooling heat dissipation mod and the wet-cooling heat dissipation mode is determined through the target heat dissipation information, so that the selection of the heat dissipation mode of the cooling tower is related to the cooling effect of the cooling tower itself, rather than the use of a single mode, and to improve the cooling effect of the cooling tower.
In related technologies, the cooling tower is a device used to cool machines such as servers. The cooling tower generally includes a dry-cooling heat dissipation system and a wet-cooling heat dissipation system. The dry-cooling heat dissipation system means that the circulation of air in the tower is achieved through the rotation of the heat dissipation fan, in turn achieving the cooling of the air inside the tower. The wet-cooling heat dissipation system means that a spray pipe is set up at the top of the tower, a heat dissipation coil is set up below the spray pipe, the spray pipe spray water onto the heat dissipation coil, and there is a water collecting tray below the heat dissipation coil, and the water in the water collecting tray is then collected again through the heat dissipation coil; so that achieving the cooling of the water circulation. At present, the cooling tower generally operate using the dry-cooling heat dissipation system or the wet-cooling heat dissipation system, this operation manner is relatively single, which leads to the cooling tower is prone to insufficient or excessive cooling, resulting in lower operational efficiency of the cooling tower.
In order to solve the above problem, in the technical solution of the present disclosure, a cooling tower identifier can be set for each cooling tower, and the mode control of the corresponding cooling tower can be achieved through the cooling tower identifier. When controlling the mode of a single cooling tower, the target heat dissipation information of the cooling tower can be collected, and the actual heat dissipation requirement of the cooling tower can be detected through the target heat dissipation information, so that the cooling tower can operate in a cooling mode corresponding to the actual heat dissipation requirement, ensuring the heat dissipation effect of the cooling tower while making the heat dissipation process more stable, avoiding phenomena such as excessive cooling or insufficient cooling, and improving the operating effect of the cooling tower.

Step 301, in response to a heat dissipation control request, obtaining a cooling tower identifier in the heat dissipation control request, and collecting target heat dissipation information of a cooling tower corresponding to the cooling tower identifier.
In an implementation, the heat dissipation control request can include a heat dissipation control request triggered by a user, or initiating a heat dissipation control request of the cooling tower when the cooling tower is started. The heat dissipation control request can refer to a request generated based on a cooling tower identifier of any cooling tower. The heat dissipation control request can indicate that performing heat dissipation control on the cooling tower with the cooling tower identifier.
The obtaining the cooling tower identifier in the heat dissipation control request can include: parsing the heat dissipation control request, the heat dissipation control request may be a URL request, and reading the cooling tower identifier from the heat dissipation control request.
In an implementation, the collecting the target heat dissipation information of the cooling tower corresponding to the cooling tower identifier can include: generating an information collection instruction based on an information collection strategy, and sending the information collection instruction to each sensor in the cooling tower, so as to receive the target heat dissipation information uploaded by each sensor in accordance with the information collection strategy.
The target heat dissipation information can refer to a value of a heat dissipation parameter collected according to the information collection strategy. The heat dissipation parameter can include at least one of the following: an ambient temperature outside a tower, a liquid supply temperature inside a tower, a water collecting tray temperature, and a liquid height of the cooling tower.
The ambient temperature outside the tower can be collected through a temperature sensor provided outside the cooling tower. The liquid supply temperature inside the tower can be collected through a temperature sensor provided at a liquid supply port on the cooling coil. The water collecting tray temperature can be collected through a temperature sensor provided at a bottom or at a height threshold of the water collecting tray. The liquid height is detected through the position sensor provided on the water collecting tray.
Step 302, if it is detected that the target heat dissipation information meets a dry-cooling heat dissipation requirement, controlling a dry-cooling heat dissipation system to operate, so as to adopt a dry-cooling heat dissipation mode for heat dissipation.
In an implementation, if it is detected that a heat dissipation requirement indicated by the target heat dissipation information is low; determining that the dry-cooling heat dissipation requirement is met. The controlling the dry-cooling heat dissipation system to operate can include: starting a cooling fan of the dry-cooling heat dissipation system, and controlling the cooling fan to move at a certain operating frequency.
Step 303, if it is detected that the target heat dissipation information meets a wet-cooling heat dissipation requirement, controlling a wet-cooling heat dissipation system to operate, so as to adopt a wet-cooling heat dissipation mode for heat dissipation.
In an implementation, the detecting that the target heat dissipation information meets the wet-cooling heat dissipation requirement can include: if it is detected that the heat dissipation requirement of the cooling tower indicated by the target heat dissipation information is high, determining that the cooling tower needs to start the wet-cooling heat dissipation mode, and thus the wet-cooling heat dissipation mode can operate normally.
In an implementation, the controlling the wet-cooling heat dissipation system to operate can include: controlling the spray pipe of the wet-cooling heat dissipation system to start spraying, controlling a cooling liquid inlet of the heat dissipation coil of the wet-cooling heat dissipation system to start inputting liquid into the heat dissipation coil, and outputting liquid from a cooling liquid outlet.
Step 304, if it is detected that the target heat dissipation information meets neither the dry-cooling heat dissipation requirement nor the wet-cooling heat dissipation requirement, controlling the wet-cooling heat dissipation system and the dry-cooling heat dissipation system to operate simultaneously, so as to adopt both the dry-cooling heat dissipation mode and the wet-cooling heat dissipation mode for heat dissipation.
In an implementation, the detecting that the target heat dissipation information meets neither the dry-cooling heat dissipation requirement nor the wet-cooling heat dissipation requirement can include: detecting that other situations other than the target heat dissipation information meeting the dry-cooling heat dissipation requirement does not meet the dry-cooling heat dissipation requirement, and detecting that other situations other than the target heat dissipation information meeting the wet-cooling heat dissipation requirement does not meet the wet-cooling heat dissipation requirement.
The controlling the wet-cooling heat dissipation system and the dry-cooling heat dissipation system to operate simultaneously can include: controlling the cooling fan of the dry-cooling heat dissipation system to start, so as to start the dry-cooling heat dissipation system, while simultaneously starting liquid delivery and spraying of the wet-cooling heat dissipation system.
In an implementation, the detecting that the target heat dissipation information meets neither the dry-cooling heat dissipation requirement nor the wet-cooling heat dissipation requirement can include: determining that neither the dry-cooling heat dissipation requirement nor the wet-cooling heat dissipation requirement is met based on at least one of the ambient temperature outside the tower, the liquid supply temperature inside the tower, the water collecting tray temperature, and the liquid height.
Taking the ambient temperature outside the tower as an example, when the ambient temperature outside the tower is less than the first temperature threshold, the dry-cooling heat dissipation requirement is met. When the ambient temperature outside the tower is greater than the third temperature threshold, the wet-cooling heat dissipation requirement is met. The third temperature threshold is greater than the first temperature threshold. When the ambient temperature outside the tower is greater than the first temperature threshold and less than the third temperature threshold, that is, within the range of [first temperature threshold, third temperature threshold], it meets neither the dry-cooling heat dissipation requirement nor the wet-cooling heat dissipation requirement. Of course, the above-mentioned manner is only exemplary, and when the target heat dissipation information meets neither the dry-cooling heat dissipation requirement nor the wet-cooling heat dissipation requirement, a heat dissipation mode that meets a combination of the wet-cooling heat dissipation mode and the dry-cooling heat dissipation mode can be determined.
In the technical solution of the present disclosure, a cooling tower identifier can be set for each cooling tower, and the mode control of the corresponding cooling tower can be achieved through the cooling tower identifier. When controlling the mode of a single cooling tower, the target heat dissipation information of the cooling tower can be collected, and the actual heat dissipation requirement of the cooling tower can be detected through the target heat dissipation information, so that the cooling tower can operate in a cooling mode corresponding to the actual heat dissipation requirement. That is, when the target heat dissipation information meets the dry-cooling heat dissipation requirement, the dry-cooling heat dissipation mode is used; when the target heat dissipation information meets the wet-cooling heat dissipation requirement, the wet-cooling heat dissipation mode is used; in the case where neither the dry-cooling heat dissipation requirement nor the wet-cooling heat dissipation is met, both the dry-cooling and wet-cooling heat dissipation modes are used; achieving the effect of selecting the corresponding heat dissipation mode according to the actual heat dissipation requirement of the cooling tower. And then, ensuring the heat dissipation effect of the cooling tower while making the heat dissipation process more stable, avoiding phenomena such as excessive cooling or insufficient cooling, and improving the operating effect of the cooling tower.
The heat dissipation effect of the wet-cooling heat dissipation system is greater than that of the dry-cooling heat dissipation system.
Further, on the basic of any one of the embodiments described above, the detecting that the target heat dissipation information meets the dry-cooling heat dissipation requirement includes:
In an implementation, the first temperature threshold can be a preset temperature threshold, and the second temperature threshold can be a preset temperature threshold. The first temperature threshold is less than the second temperature threshold, for example, the first temperature threshold may be 5 degrees Celsius and the second temperature threshold may be 25 degrees Celsius.
It should be noted that the first temperature threshold, second temperature threshold, third temperature threshold, fourth temperature threshold, etc. in the present disclosure are only used to distinguish temperature thresholds with different values from names, and do not have specific meanings of order or size.
The detecting that the temperature difference between the liquid supply temperature and the preset target temperature is greater than the preset temperature difference threshold can include: calculating the temperature difference between the liquid supply temperature and the preset target temperature, and determining that the temperature difference is greater than the temperature difference threshold. If both the height threshold and the temperature difference threshold meet the dry-cooling heat dissipation mode, determining that the dry-cooling heat dissipation requirement is met.
In an implementation, if it is detected that the water collecting tray temperature is greater than the second temperature threshold, determining that the target heat dissipation information meets the dry-cooling heat dissipation requirement; if it is detected again that the temperature inside the water collecting tray is less than a heating threshold, it indicates that the water temperature inside the water collecting tray is low and there is a risk of icing; thus, determining that the target heat dissipation information meets the wet-cooling heat dissipation requirement, and turning on spraying. The heating threshold can be, for example, a temperature close to a freezing temperature, which is 0 degrees Celsius. The heating threshold can be, for example, 2 degrees Celsius or 1 degrees Celsius.
For ease of understanding,
In the technical solution of the present disclosure, different information dimensions are set through the target heat dissipation information, such as any one of the ambient temperature, the liquid supply temperature, the water collecting tray temperature, or the liquid height. Furthermore, when the ambient temperature outside the tower is less than the first temperature threshold, the dry-cooling heat dissipation is used to reduce spraying. Or, when the liquid supply temperature is less than the preset second temperature threshold, it indicates that the liquid supply temperature is low and there is no need for excessive cooling, the dry-cooling heat dissipation mode can be used. Or, if the water collecting tray temperature is greater than the second temperature threshold, the temperature in the water collection tank is higher, and the water temperature in the water collecting tray is higher, which greatly reduces the possibility of icing. At this time, there is no need to spray anymore, and the dry-cooling heat dissipation mode can be used to achieve the purpose of saving energy consumption. Or, if it is detected that the temperature difference between the liquid supply temperature and the preset target temperature is greater than the preset temperature difference threshold, the liquid supply temperature is lower, and the dry-cooling heat dissipation mode can be used. Or, if the liquid height is less than the height threshold, it indicates that the water level in the water collecting tray is low; if the wet-cooling heat dissipation is continued to be used, there may be a phenomenon of wet cooling idling. At this point, the wet-cooling heat dissipation can no longer be used, thus, the dry-cooling heat dissipation can be used. Based on the comparison between any of the above dimensions and the corresponding threshold, it is possible to detect whether the target heat dissipation information meets the dry-cooling heat dissipation requirement, and achieving that directly detecting the dry-cooling heat dissipation requirement using the target heat dissipation information, completing the rapid detection and judgment of the dry-cooling heat dissipation mode.
Further, on the basic of any one of the embodiments described above, the detecting that the target heat dissipation information meets the wet-cooling heat dissipation requirement includes:
In an implementation, both the third temperature threshold and the fourth temperature threshold can be a preset temperature threshold. In an implementation, the third temperature threshold can be 10 degrees Celsius, and the fourth temperature threshold can be 30 degrees Celsius. The third temperature threshold is greater than the first temperature threshold, and the fourth temperature threshold is greater than the second temperature threshold.
In an implementation, the third temperature threshold can be obtained by presetting. The fourth temperature threshold can be obtained by setting. For example, the third temperature threshold can be set to 10 degrees Celsius, and the fourth temperature threshold can be set to 30 degrees Celsius.
The target heat dissipation information can refer to heat dissipation information collected through the parameter collection strategy. Of course, in the technical solution of the present disclosure, a plurality of parameters such as the ambient temperature outside the tower, the liquid supply temperature inside the tower, the water collecting tray temperature, and the liquid height of the cooling tower can also be collected simultaneously, and the above-mentioned wet-cooling heat dissipation needs are set one by one to achieve the detection of the wet-cooling heat dissipation.
For ease of understanding,
In the technical solution of the present disclosure, in a case of the target heat dissipation information including the liquid height, the ambient temperature outside the tower, and the liquid supply temperature, if the liquid height is greater than or equal to the preset height threshold, it indicates that the water in the water collecting tray is sufficient, and wet cooling can be carried out. Furthermore, when the liquid height is greater than or equal to the preset height threshold, and the ambient temperature outside the tower is less than the preset first temperature threshold, it indicates that the ambient temperature of the cooling tower is low, and wet cooling alone can meet the cooling requirement of the server. At this time, the wet-cooling heat dissipation mode can be used. Or, in a case where the water collecting tray temperature is less than the first temperature threshold, it indicates that the temperature of the liquid inside the water collecting tray is low; if the wet-cooling heat dissipation is not started, there is a high possibility that the liquid in the water collecting tray will freeze. In order to ensure the continuous operation of the wet-cooling heat dissipation system, the wet-cooling heat dissipation mode can be adopted when the water collecting tray temperature is low; so as to reduce or avoid liquid freezing inside the water collecting tray through the liquid circulation inside the water collecting tray, so that both heat dissipation modes of the cooling tower can operate normally.
In practical applications, when the external temperature is low; the liquid in the spray pipe and water collecting tray inside the cooling tower needs to be manually emptied to avoid freezing. This control manner is more complex to operate, and the control efficiency of the cooling tower is low. When the water collecting tray temperature or the external ambient temperature is low; and there is no water level warning in the water collecting tray, the wet-cooling heat dissipation mode is adopted, so as to ensure that the wet-cooling system inside the cooling tower is still operating normally, avoiding icing.
Further, on the basic of any one of the embodiments described above, the collecting the target heat dissipation information of the cooling tower includes:
In an implementation, according to the dry-cooling heat dissipation mode and wet-cooling heat dissipation cooling mode supported by the cooling tower, collecting at least one of the following: the ambient temperature outside the tower, the liquid supply temperature inside the tower, the water collecting tray temperature, and the liquid height of the cooling tower.
The parameter collection strategy can be set according to actual analysis needs, which can include one parameter to be collected or a plurality of parameter values to be collected. The parameter collection strategy can include information such as collection frequency, collection time, and collected parameters. According to the parameter collection strategy, at least one parameter of the cooling tower can be collected, such as the ambient temperature outside the tower, the liquid supply temperature, the water collecting tray temperature, and the liquid height.
In the technical solution of the present disclosure, when collecting the target heat dissipation information of the cooling tower, at least one of the ambient temperature outside the tower, the liquid supply temperature, the water collecting tray temperature and liquid height is collected as the target heat dissipation information based on the preset parameter collection strategy, achieving on-demand collection of the target heat dissipation information, and avoiding invalid collection of the target heat dissipation information.
In the technical solution of the present disclosure, a bypass valve can be provided for the heat dissipation coil of the wet-cooling heat dissipation system, and the liquid flow rate of the heat dissipation coil can be controlled through the bypass valve to achieve liquid flow rate control.
As shown in
Step 601, opening a bypass valve of the wet-cooling heat dissipation system to start a liquid supply of the wet-cooling heat dissipation system when the cooling tower is turned on.
In an implementation, the turning on the cooling tower can include controlling the cooling tower to turn on in response to a turn-on instruction triggered by a user. When the cooling tower is turned on, liquid can be injected into the heat dissipation coil of the cooling tower to allow the liquid inside the heat dissipation coil to flow, achieving heat dissipation inside the tower. The heat dissipation coil can include a cooling liquid inlet and a cooling liquid outlet. The cooling liquid inlet is continuously injected with liquid, while the cooling liquid outlet is continuously discharged with liquid, thereby achieving liquid flow inside the heat dissipation coil to remove heat. The bypass valve can be provided at the cooling liquid inlet of the heat dissipation coil, and the flow rate of the cooling liquid can be controlled through the bypass valve.
Step 602, if it is detected that a liquid supply temperature of the wet-cooling heat dissipation system is greater than a preset second temperature threshold, controlling the dry-cooling heat dissipation system to operate, and controlling an operating frequency of a heat dissipation fan of the dry-cooling heat dissipation system through a PID (Proportional-Integral-Derivative) adjustment algorithm.
In an implementation, the value of the second temperature threshold can refer to the description of the previous embodiments. When the liquid supply temperature is greater than the second temperature threshold, it indicates that the supply liquid temperature is high, and the heat dissipation needs to be initiated. At this time, the dry-cooling heat dissipation system can be started.
The controlling an operating frequency of a heat dissipation fan of the dry-cooling heat dissipation system through a PID adjustment algorithm can include: calculating the operating frequency of the heat dissipation fan of the dry-cooling heat dissipation system through the PID adjustment algorithm, generating an operating instruction of the heat dissipation fan based on the operating frequency, sending the operating instruction of the heat dissipation fan to the heat dissipation fan of the cooling tower, where the operating instruction instructs the heat dissipation fan to operate according to the operating frequency in the operating instruction.
Furthermore, the operating frequency can refer to a number of rotations of the heat dissipation fan per unit time period. For example, the operating frequency is 5 times/second. Of course, in practical applications, a maximum operating frequency and a minimum operating frequency of the heat dissipation fan can be set. The maximum operating frequency can refer to a maximum number of rotation times of the heat dissipation fan per unit time period. The minimum operating frequency can refer to a minimum number of rotation times of the heat dissipation fan per unit time period. The values of maximum and minimum rotation times can be set according to usage requirements, and this is not limited too much in this embodiment.
In a technical solution of an embodiment of the present disclosure, a bypass valve of the wet-cooling heat dissipation system can be opened to start a liquid supply of the wet-cooling heat dissipation system when the cooling tower is turned on. In addition, in a case where it is detected that a liquid supply temperature of the wet-cooling heat dissipation system is greater than a preset second temperature threshold, controlling the dry-cooling heat dissipation system to operate, that is, during the initial start-up of the cooling tower, supplying liquid to the wet-cooling heat dissipation system, but does not activate the spraying of the wet-cooling heat dissipation system. As time goes by; the liquid supply temperature in the wet-cooling heat dissipation system continues to rise, it indicates that the temperature inside the cooling tower is constantly increasing. Therefore, when the liquid supply temperature is greater than the second temperature threshold, the dry-cooling heat dissipation system can be started, and the operating frequency of the heat dissipation fan of the dry-cooling heat dissipation system can be controlled through the PID adjustment algorithm. When the cooling tower is turned on, the dry-cooling heat dissipation system is not directly started, instead, the dry-cooling heat dissipation system is started when the liquid supply temperature is high, avoiding starting the dry-cooling heat dissipation system when cooling is not required, and improving the cooling effect.
As shown in
Step 701, detecting a number of mode switching times between the dry-cooling heat dissipation mode and the wet-cooling heat dissipation mode during a target time period.
In an implementation, the target time period can refer to a set duration, such as 1 hour. When switching from the dry-cooling heat dissipation mode to the wet-cooling heat dissipation mode, it can be determined that the number of mode switching times increases by 1. When switching from the wet-cooling heat dissipation mode to the dry-cooling heat dissipation mode, it can be determined that the number of mode switching times increases by 1.
Furthermore, during the operation of the cooling tower, a switching node from the dry-cooling heat dissipation mode to the wet-cooling heat dissipation mode and a switching node from the wet-cooling heat dissipation mode to the dry-cooling heat dissipation mode can be recorded. Each switching node can be associated with a switching time. It is possible to determine the number of switching nodes whose switching time is within the target time period, so as to determine the number of switching nodes as the number of mode switching times between the dry-cooling heat dissipation mode and the wet-cooling heat dissipation mode within the target time period.
Step 702, if it is determined that the number of mode switching times is greater than a preset number threshold, controlling the heat dissipation fan of the dry-cooling heat dissipation system to operate at a lowest frequency in a case of controlling the wet-cooling heat dissipation system to operate.
In an implementation, the number threshold is a pre-set number of mode switching times. The controlling the heat dissipation fan of the dry-cooling heat dissipation system to operate at the lowest frequency can include: generating the operating instruction according to the minimum operating frequency, that is, the minimum operating frequency, of the heat dissipation fan, and sending the operating instruction to the cooling tower, where the operation instruction indicates the heat dissipation fan of the cooling tower to operate at a lowest frequency. Specifically, it can refer to a microcontroller of the heat dissipation fan of the cooling tower, the heat dissipation fan is controlled by the microcontroller to operate at the lowest frequency.
In the technical solution of the present disclosure, if the number of mode switching times between the dry-cooling heat dissipation mode and the wet-cooling heat dissipation mode during the target time period is greater than the preset number threshold, the cooling tower frequently switch between the dry-cooling and wet-cooling modes. At this time, the operating mode of the cooling tower is not stable enough. Therefore, the wet-cooling heat dissipation mode can be activated and the heat dissipation fan of the dry-cooling heat dissipation system can be controlled to operate at the lowest frequency, thereby avoiding frequent switching between the dry-cooling and wet-cooling heat dissipation modes, and improving the operating stability of the cooling tower.
Further, on the basic of any one of the embodiments described above, after the controlling the heat dissipation fan of the dry-cooling heat dissipation system to operate at the lowest frequency in the case of controlling the wet-cooling heat dissipation system to operate, the method further includes:
Partial content of this embodiment is the same as partial content of the preceding embodiments, which can be described with reference to the above embodiments, and will not be repeated herein.
In the technical solution of the present disclosure, the liquid supply temperature of the wet-cooling heat dissipation system in the wet-cooling heat dissipation mode is collected, and when the liquid supply temperature is less than the second temperature threshold, the wet-cooling heat dissipation mode is turned off, and the heat dissipation fan of the wet-cooling heat dissipation system is controlled to operate at the maximum frequency. Thus, when the liquid supply temperature is low; switching to the dry-cooling heat dissipation, avoiding unnecessary wet-cooling heat dissipation, and improving the operating efficiency of the cooling tower.
Further, on the basic of any one of the embodiments described above, after the controlling the heat dissipation fan of the dry-cooling heat dissipation system to operate at the maximum frequency, the method further includes:
In an implementation, the fifth temperature threshold can be set according to a usage requirement. For example, the fifth temperature threshold can be set to 35 degrees Celsius.
The collecting the liquid supply temperature in the wet-cooling heat dissipation system can include: collecting the liquid supply temperature in the wet-cooling heat dissipation system according to a wet-cooling collection frequency. Further, the wet-cooling collection frequency can be set according to a usage requirement.
In the technical solution of the present disclosure, when the liquid supply temperature in the wet-cooling heat dissipation system is greater than the fifth temperature threshold, it indicates that even if the dry-cooling heat dissipation system operates at the maximum frequency, the liquid supply temperature in the cooling tower is still high, and the dry-cooling heat dissipation mode can no longer meet the cooling requirements. Therefore, it is necessary to start the wet-cooling heat dissipation system and control the heat dissipation fan of the dry-cooling heat dissipation system to operate at the lowest frequency, ensuring that the cooling tower can meet the cooling requirements, and improving the cooling effect of the cooling tower.
Further, after the controlling the heat dissipation fan of the dry-cooling heat dissipation system to operate at the lowest frequency in a case of controlling the wet-cooling heat dissipation system to operate, the method further includes:
In an implementation, the opening degree of the bypass valve can refer to a ratio of a real-time liquid input speed of the heat dissipation coil to a maximum input speed of the heat dissipation coil under the control of the bypass valve. The larger the opening degree, the higher the input flow rate of the cooling liquid in the heat dissipation coil, and the smaller the opening degree, the lower the input flow rate of the cooling liquid in the heat dissipation coil.
The target opening degree of the bypass valve can be calculated through the PID adjustment algorithm, so as to control the bypass valve to control the flow rate of the cooling liquid using the target opening degree. For example, when the opening degree of the bypass valve is 30%, the target opening of the bypass valve can be obtained through calculating a product of the maximum opening degree of the bypass valve and 0.3. Of course, in practical applications, the target opening degree can be issued to the bypass valve in the form of an instruction, and the instruction can instruct the bypass valve to adjust to the target opening degree.
The first opening degree threshold can be less than the second opening degree threshold. The values of the first opening degree threshold and the second opening degree threshold can be set according to a usage requirement. For example, the first opening degree threshold can be set to 30%, and the second opening degree threshold can be set to 30%.
Partial content of this embodiment is the same as partial content of the above-mentioned embodiments, and will not be repeated herein.
In the technical solution of the present disclosure, when the opening degree of the bypass valve is less than the preset first opening degree threshold, the target opening degree of the bypass valve is calculated through the PID adjustment algorithm; and then, when the opening degree of the bypass valve is small, achieving automatic adjustment and control of the bypass valve using the PID adjustment algorithm, and realizing intelligent wet-cooling heat dissipation control. When it is detected that the opening degree of the bypass valve of the wet-cooling heat dissipation system is greater than the preset second opening degree threshold, closing the bypass valve to turn off the wet-cooling heat dissipation system, controlling the dry-cooling heat dissipation system to operate, and controlling the operating frequency of the heat dissipation fan of the dry-cooling heat dissipation system through a PID adjustment algorithm, which achieves automatic adjustment of the heat dissipation fan under the dry-cooling heat dissipation system. Through the PID adjustment algorithm, achieving a real-time adjustment of the control effect of the cooling system of the cooling tower, making the cooling effect of the cooling tower more matched with the actual cooling requirement, and improving the operating efficiency of the cooling tower.
