The method aims at solving the problems that when the existing refrigeration is carried out in a mixed mode in a high-humidity and high-heat area, a compressor needs to be started for a long time and is not cold, and a large amount of energy is inevitably consumed due to low refrigeration efficiency of the compressor. An embodiment of the present invention provides an optimization method for data center temperature control, as shown in fig. 1, the method includes:
101. and acquiring the temperature of the data center machine room.
The temperature of the data center machine room can be uploaded to the control system in real time by configuring a temperature sensor in the data center machine room.

102. And calculating the temperature regulation and control amplitude according to the temperature of the data center machine room and a preset target temperature.
It should be noted that the temperature in the data center machine room includes low-end temperature and high-end temperature, wherein, low-end temperature is return air side temperature, because the return air is the air after the evaporative cooling system cooling, its temperature is relatively lower, and high-end temperature is data center machine room air-out side, and the return air that flows through the data center machine room promptly, because the heat dissipation conduction of a large amount of servers in the machine room leads to air-out side temperature on the high side. And the data center computer lab temperature in this application embodiment can be low side temperature, also can be high side temperature, and when data center computer lab temperature was low side temperature, corresponding target temperature of predetermineeing also is predetermined low side temperature, if be 18 degrees centigrade, and is the same, and when data center computer lab temperature was high side temperature, corresponding target temperature of predetermineeing also is predetermined high side temperature, if be 27 degrees centigrade.
After the temperature sensor transmits the acquired temperature signal to a PI controller in the data center temperature control optimization system, the controller calculates according to the current data center room temperature to obtain a corresponding temperature control amplitude, where the temperature control amplitude may be a percentage of a temperature difference to be controlled, and for example, the temperature control amplitude is 35%, which means that an adjustable amount between the current data center room temperature and a preset target temperature is 35%, but not limited thereto.
103. And determining the temperature regulation strategy of the data center machine room according to the mapping relation between the preset temperature regulation amplitude and the temperature regulation strategy.
Different temperature control strategies correspond to different cooling devices, and the larger the temperature control amplitude is, the more the cooling devices are started in the corresponding temperature control strategies.
In a specific implementation process, the temperature regulation and control amplitude can be divided into a plurality of intervals, and each interval corresponds to a corresponding temperature regulation and control strategy, so that when the temperature regulation and control amplitude is calculated according to the current temperature of the data center machine room, the temperature regulation and control amplitude can be mapped to the corresponding regulation and control strategy according to the interval to which the temperature regulation and control amplitude belongs.
104. And controlling cooling equipment in the evaporation cooling system according to the temperature regulation and control strategy.
Wherein, the cooling equipment at least comprises fresh air equipment, a spraying device and a freezing water coil pipe.
It should be noted that the evaporative cooling system can utilize the outdoor new trend that new trend equipment provided, in the passageway with the indirect contact of the hot return air in the data center computer lab, because the sensible heat difference in temperature has between the hot return air that outdoor new trend and data center computer lab outflow, this sensible heat difference can be as drive power, make the heat-conduction through the passageway wall pipe with the computer lab server heat that carries in the use air in the computer lab, transmit the outdoor new trend in the new trend equipment, and the computer lab return air can also be cooled down through the cooling medium via the refrigerated water coil pipe, thereby reach the purpose of cooling data center computer lab return air.
In the embodiment of the application, multiple control strategies are configured, and different cooling devices are correspondingly started in each control strategy, or different operation modes of the same cooling device are started, so that the corresponding regulation mode is selected according to the regulation range between the current temperature of the data center machine room and the preset target temperature, the problem of resource waste caused by invalid or excessive regulation of the temperature of the data center machine room is avoided, and the performance of the temperature regulation of the data center machine room is improved.
In an embodiment of the present invention, in order to fully illustrate the implementation process of the embodiment, another optimization method for temperature control of a data center is provided, as shown in fig. 2, the method includes:
201. and acquiring the temperature of the data center machine room.
The temperature of the data center machine room can be obtained by configuring a temperature sensor in the data center machine room, so that the real-time temperature acquired by the temperature sensor is uploaded to the control system. The frequency of the temperature collected and uploaded by the sensor to the data center machine room can be set according to different application scenes, so that the real-time temperature in the data center machine room can be monitored, regulated and controlled.
202. And calculating the temperature regulation and control amplitude according to the temperature of the data center machine room and a preset target temperature.
The temperature control range is calculated by a controller in the temperature control system, and the output parameter of the controller can be set according to different application scenarios, such as the percentage of the temperature difference to be controlled, but not limited thereto.
203. And determining the temperature regulation strategy of the data center machine room according to the mapping relation between the preset temperature regulation amplitude and the temperature regulation strategy.
In the embodiment of the application, the temperature control range can be divided into a plurality of ranges according to the prior condition, and a mapping relation between each range and the control strategy is established, for example, when the temperature of the data center machine room is low, excessive cooling equipment does not need to be started, only one of the cooling equipment can be started in the control strategy corresponding to the temperature control range, and along with the temperature rise of the data center machine room, a plurality of cooling equipment need to be started simultaneously in the control strategy corresponding to the temperature control range to which the data center machine room belongs, and the cooling equipment can correspond to different operation modes in the same control strategy.
Furthermore, the temperature regulation strategy at least comprises a primary regulation strategy, a secondary regulation strategy and a tertiary regulation strategy, wherein the primary regulation strategy is used for controlling the opening of the fresh air equipment; the secondary control strategy is to control the fresh air equipment to be started and control the spraying device to be started; the three-level control strategy is to control the fresh air device to be started, control the spraying device to be started and control the freezing medium to be input into the freezing water coil.
The temperature regulation strategy in the embodiment of the present application corresponds to different refrigeration modes, which specifically includes:
the primary temperature regulation and control strategy can be applied to a winter room when the outdoor dry bulb temperature is low, the spraying device is not started at the moment, the freezing medium does not need to flow in the freezing water coil, and only outdoor fresh air is used for cooling through fresh air equipment;
the secondary temperature regulation strategy is that when the external environment temperature is relatively mild and the relative humidity is not high, the unit operates in the mode, the spraying device is started at the moment, and the freezing medium still does not need to flow in the freezing water coil pipe. A spray head of the spraying device sprays into the channel, and outdoor fresh air is subjected to direct evaporative cooling and the like in the channel and is indirectly contacted with return air of a machine room after being cooled to take away heat;
the three-level temperature regulation strategy means that when the outdoor dry-wet bulb temperature is higher, the fresh air equipment and the spraying device in the system are only started and cannot meet the requirement of cold quantity, and at the moment, the unit operates in the mode. The spraying device sprays into the channel, and fresh air input by the fresh air equipment enters the channel to directly contact with water mist for evaporative cooling and enthalpy reduction and then indirectly contact with return air of the machine room to take away heat. And then the return air with higher temperature in the data center machine room is cooled again through a freezing water coil pipe circulating cooling medium and then is sent into the data center machine room.
204a, when the temperature regulation strategy is the primary regulation strategy, determining the opening degree of a fresh air valve of the fresh air equipment according to the temperature regulation and control amplitude and a preset proportional regulation relation.
The preset proportional adjustment relationship may be a direct proportional relationship. The primary regulation strategy corresponds to a certain temperature regulation amplitude threshold, if the temperature regulation amplitude is 40%, namely when the output value of the PI controller is between 0% and 40%, the temperature regulation mode is determined to be the primary regulation strategy, only the fresh air equipment is started at the moment, and the opening of a fresh air valve of the fresh air equipment can be adjusted according to a preset proportion and determined according to the temperature regulation amplitude. The preset proportional adjustment relationship between the opening of the fresh air valve and the temperature adjustment and control range may be, but is not limited to, a direct proportional relationship.
205a, controlling the fresh air equipment to convey fresh air under the opening degree of the fresh air valve.
In the embodiment of the application, the fresh air valve of the fresh air equipment is in different opening degrees and carries out outdoor fresh air conveying according to different temperature regulation and control amplitudes by configuring a proportion regulation relation and under the same-level temperature regulation and control strategy, so that the air return cooling requirement of a data center machine room can be met, the resource waste is avoided, and the temperature regulation and control performance of the data center machine room is improved.
And a step 204b parallel to the step 204a, when the temperature regulation strategy is the secondary regulation strategy, controlling the opening of a fresh air valve of the fresh air equipment to be a maximum value, and determining a first spraying mode of the spraying device according to the temperature regulation amplitude and a preset spraying rule.
According to the above content, when the temperature regulation strategy is a two-stage regulation strategy, it is indicated that only the fresh air equipment is started, and the requirement of cooling by air return of the data center machine room cannot be met, and at the moment, the spraying device needs to be started under the condition that the fresh air equipment is completely started.
The spray head of the spraying device is provided with a plurality of spray outlets, and the more the spray outlets are opened, the larger the spray amount is. Similarly, a certain temperature regulation and control interval is corresponded to under the secondary regulation and control strategy, and the number of the spray nozzles can be changed along with the change of the temperature regulation and control amplitude between the minimum temperature regulation and control amplitude threshold value and the maximum temperature regulation and control amplitude threshold value of the secondary regulation and control strategy, so that the problem of poor cooling effect or excessive regulation and control is avoided. In addition, because the arrangement modes and the number of the spraying ports of different spraying devices are different, the common spraying devices and respective incremental spraying modes can be stored in advance in the embodiment of the application, so that when the temperature of the data center machine room is regulated, corresponding preset spraying rules are extracted according to the acquired spraying device identification, and then the spraying mode of the spraying device is determined according to the current temperature regulation and control amplitude and the preset spraying rules.
205b, controlling the spraying device to spray in a first spraying mode.
Illustratively, the spray heads of the spraying device are arranged in a form of 5X5, and the preset spraying rules comprise that the middle 3X3 spray head is opened at low spraying amount, the middle 3X5 spray head is opened at medium spraying amount, and all spray heads are opened at high spraying amount. When the current temperature regulation strategy is judged to be a secondary regulation strategy according to the temperature regulation amplitude, firstly, the fresh air valve of the fresh air equipment is determined to be opened at the maximum opening, and the spraying device is determined to operate in a medium spraying amount mode according to the temperature regulation amplitude, and then the 3X5 spray head in the middle of the spraying device is controlled to spray.
In order to effectively utilize the atomizer to avoid the wasting of resources, this application embodiment still includes: when the temperature regulation amplitude is monitored to be increased, controlling the spraying device to spray in a second spraying mode, wherein the spraying amount in the second spraying mode is greater than that in the first spraying mode; or
And when the temperature regulation amplitude is monitored to be reduced, controlling the spraying device to spray in a third spraying mode, wherein the spraying amount in the third spraying mode is smaller than that in the first spraying mode.
In a specific application process, along with the continuous propulsion of the cooling process, the temperature of the data center machine room gradually approaches to the preset target temperature, which means that the temperature regulation and control amplitude is gradually reduced, and when the temperature is reduced enough, the spraying amount can be reduced, namely, the spraying device is controlled to be switched from a higher-amount spraying mode to a lower-amount spraying mode. Conversely, in the cooling process, the temperature of the data center room is increased due to the increase of the number of the servers, and at this time, the spraying device is controlled to be switched from the lower-amount spraying mode to the higher-amount spraying mode.
In the embodiment of the application, the spraying mode of the spraying device is dynamically adjusted according to the temperature regulation and control amplitude and the preset spraying rule, so that the temperature regulation and control system can adaptively switch the spraying mode, and a better temperature regulation and control effect is realized.
And 204c, which is parallel to the steps 204a and 204b, when the temperature regulation strategy is the three-level regulation strategy, controlling the opening degree of a fresh air valve of the fresh air equipment to be the maximum value, controlling the spraying device to spray in a fourth spraying mode, and determining the opening degree of the regulating valve of the chilled water coil according to the temperature regulation amplitude and a preset regulating rule of the regulating valve.
Wherein the spraying amount of the spraying device in the fourth spraying mode is maximum.
According to the above content, when the temperature regulation strategy is a three-level regulation strategy, it is indicated that only the fresh air equipment and the spraying device are started at the moment, and the requirements of cooling by air return cooling of a data center machine room cannot be met, and at the moment, the freezing medium needs to be input into the freezing water coil pipe under the conditions that the fresh air equipment is completely started and the spraying device sprays with the maximum spraying amount.
205c, controlling the flow of the medium input into the chilled water coil according to the opening degree of the regulating valve.
Similarly, the input flow of the freezing medium in the chilled water coil can be regulated, the mapping relation between the temperature regulation and control amplitude and the opening of the regulating valve is established according to the prior condition, the opening of the regulating valve is controlled according to the real-time temperature regulation and control amplitude, so that the flow of the freezing medium input into the chilled water coil is controlled, the preset temperature regulation and control effect is ensured, and the problems of excessive temperature regulation and resource waste are avoided.
Further, the embodiment of the application comprises: and after the temperature reduction equipment in the evaporation cooling system is controlled according to the three-level regulation and control strategy to accumulate a preset time interval, if the temperature of the data center machine room exceeds a preset temperature threshold value, outputting alarm information. The preset time interval and the preset temperature threshold may be set according to different application scenarios, and the warning information may be a warning tone, a highlighted image display, text information, and the like, which is not specifically limited in the embodiment of the present application. Under the general condition, when the temperature of the data center machine room is higher and after the temperature regulation is executed for a period of time based on the highest-level temperature regulation strategy, if the temperature in the data center machine room is still high, the current temperature of the data center machine room is abnormal, the alarm information is output, and a worker can be reminded of conducting abnormal investigation in time, so that the safety of the data center machine room is ensured.
