The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Data center refers to the infrastructure of IT equipment work, including power supply, refrigeration, rack space etc. wherein, IT equipment refers to equipment such as server, storage, switch, router, generally, data center refrigerating system is equipped with three kinds of refrigeration modes: mechanical compression refrigeration, partial natural cooling and complete natural cooling, wherein the mechanical compression refrigeration refers to a mode of generating refrigeration by compressing a refrigerant by a compressor; the complete natural cooling is a cooling mode that a natural cold source (such as external cold atmosphere) is used for heat exchange cooling instead of a compressor for compression cooling; the partial natural cooling is a refrigeration mode of simultaneously refrigerating by adopting two modes of compression refrigeration and complete natural cooling of a compressor.
In order to save the electric energy for the operation of the data center and reduce the cost of electricity charges, the traditional temperature control method for saving energy of the data center is as follows: under part IT load, the chilled water supply water temperature is increased, but the energy-saving effect that this kind of mode of increasing chilled water supply water temperature can bring is limited because after the temperature increases to a certain extent, if further increase again can lead to the problem that can not satisfy data center's refrigeration demand. In view of this, the embodiment of the present invention provides a temperature control method for energy saving of a data center, so as to further reduce energy consumption of the data center and meet higher energy saving requirements.
Example one
Fig. 1 is a flowchart of a temperature control method for energy saving of a data center according to an embodiment of the present invention, and as shown in fig. 1, the method specifically includes the following steps:
and step S102, acquiring the wet bulb temperature sent by the outdoor wet bulb temperature sensor.
Specifically, an execution main body of the temperature control method for energy saving of the Data Center provided by the embodiment of the invention is a Data Center Infrastructure management system (DCIM), in the Data Center refrigeration system, devices such as an outdoor wet bulb temperature sensor, a cooling tower, a water temperature sensor, a water pump, a water chiller, a plate heat exchanger, an electric valve (a switch valve and a regulating valve), a water pressure sensor and a water flow sensor are connected to a refrigeration station monitoring system, modular Data Center devices (such as a Data Center air conditioner, a channel temperature and humidity sensor and a train head cabinet power and the like) are connected to a moving loop monitoring system, and the refrigeration station monitoring system, the moving loop monitoring system, an electric power monitoring system and the like upload related monitoring Data to the DCIM system, and the DCIM system performs unified calculation and control to further adjust the operation condition of the Data Center refrigeration system.
In the control process of the DCIM system, the wet bulb temperature sent by the outdoor wet bulb temperature sensor needs to be acquired, and in order to ensure the timeliness of energy-saving adjustment, the outdoor wet bulb temperature can be acquired in real time. The user can also select to acquire the wet bulb temperature at regular time according to the preset time period, the embodiment of the invention does not specifically limit the acquisition mode of the wet bulb temperature, and the user can specifically set the wet bulb temperature according to actual requirements.
And step S104, determining a target cooling amplitude value based on the chilled water supply water temperature set value and the wet bulb temperature of the data center under the condition that the refrigeration system of the data center runs in complete natural cooling.
And S106, controlling the water supply temperature set value of the chilled water to reduce the target cooling amplitude and controlling the air outlet temperature of the air conditioner of the data center to reduce the target cooling amplitude under the condition that the target cooling amplitude is not zero.
In order to further reduce the energy consumption of the data center, when the refrigeration system of the data center is determined to operate in a completely natural cooling mode, the inventor thinks of a processing mode completely opposite to the energy-saving method in a mechanical compression refrigeration mode, namely, the energy consumption is further saved by reducing the set value of the chilled water supply water temperature and the air conditioner outlet air temperature, because if the set value of the chilled water supply water temperature and the air conditioner outlet air temperature can be reduced, the inlet air temperature of the IT equipment is reduced, and when the inlet air temperature is reduced, the lower the rotating speed of a fan of the IT equipment is, the lower the rotating speed is, the lower the energy consumption of the fan is, and meanwhile, the hard disk, the memory and the main board including the CPU are also influenced by the temperature, and the lower the energy consumption is reduced. The reduction of the energy consumption of the IT equipment naturally reduces the requirement of refrigerating capacity, and further reduces the energy consumption of refrigerating equipment (such as an air conditioner), thereby further reducing the energy consumption of the whole data center.
Therefore, in the embodiment of the invention, when the data center refrigerating system runs in a completely natural cold state, the DCIM system can determine the target cooling amplitude according to the chilled water supply water temperature set value and the wet bulb temperature of the data center, if the temperature difference between the chilled water supply water temperature set value and the outdoor wet bulb temperature is large enough, energy can be saved by reducing the chilled water supply water temperature set value and the air conditioner outlet air temperature, and the specific value of the temperature reduction is the target cooling amplitude; however, if the temperature difference between the chilled water supply water temperature set value and the outdoor wet bulb temperature is not large, and the determined target cooling amplitude is 0, the chilled water supply water temperature set value and the data center air conditioner outlet air temperature still need to be maintained unchanged.
According to the temperature control method for energy saving of the data center, provided by the embodiment of the invention, when a refrigeration system of the data center runs in complete natural cooling, a target cooling amplitude is determined according to a set value of chilled water supply temperature of the data center and wet bulb temperature sent by an outdoor wet bulb temperature sensor, and the set value of the chilled water supply temperature and the air outlet temperature of an air conditioner of the data center are further controlled to reduce the target cooling amplitude under the condition that the target cooling amplitude is nonzero. After the chilled water supply temperature and the air outlet temperature of the air conditioner are both reduced, the air inlet temperature of the IT equipment is reduced, the energy consumption of the IT equipment is reduced along with the reduction of the air inlet temperature, the energy consumption of the IT equipment is reduced, so that the refrigeration requirement is reduced, the energy consumption of the refrigeration equipment is reduced, the energy consumption of the whole data center is reduced, and the higher energy-saving requirement is met.
The method for temperature control for energy saving of a data center provided by the embodiment of the invention is briefly described above, and some method steps involved in the method are specifically described below.
In an alternative embodiment, as shown in fig. 2, in step S104, the determining the target cooling amplitude based on the data center chilled water supply water temperature set value and the wet bulb temperature specifically includes the following steps:
step S1041, determining whether a difference between the chilled water supply water temperature set value and the wet bulb temperature satisfies a preset cooling condition.
In order to determine whether energy saving (cost reduction) of the data center can be performed by reducing the chilled water supply water temperature set value and the air conditioner outlet air temperature, firstly, the DCIM system needs to determine whether the difference between the chilled water supply water temperature set value and the wet bulb temperature meets a preset temperature reduction condition, the embodiment of the invention does not specifically limit the preset temperature reduction condition, but the basic principle is that the value of the chilled water supply water temperature is greater than the wet bulb temperature.
In order to avoid that the wet bulb temperature change caused by the sudden change of the external temperature affects the judgment result, in an optional embodiment, the preset cooling condition includes: the difference value between the chilled water supply water temperature set value and the wet bulb temperature is greater than a preset temperature difference threshold value within a continuous preset time period before the current moment. Wherein the preset temperature difference threshold value represents a temperature difference limit value between a chilled water supply water temperature set value and a wet bulb temperature. Optionally, the preset temperature difference threshold may be set to 5 °, and the user may also set the preset temperature difference threshold to another value according to an actual requirement.
That is, if the current time is 11 00am, the preset time period is set to 30 minutes, and the preset temperature difference threshold is 5 °, the following step S1042 is executed only if the difference between the chilled water supply water temperature setting value and the wet bulb temperature is greater than 5 ° within 10 30am to 11 00am, and otherwise, step S1043 is executed.
If yes, executing step S1042; if not, go to step S1043.
Step S1042, determining a target temperature reduction amplitude value based on the difference value and a preset temperature difference threshold value.
If the preset temperature difference threshold is 5 degrees, the difference between the chilled water supply water temperature set value and the wet bulb temperature is 7 degrees, the DCIM system can determine that the target temperature reduction amplitude is 7-5 degrees =2 degrees, namely the chilled water supply water temperature set value is reduced by 2 degrees on the basis of the current set temperature, and the air conditioner temperature of the data center is reduced by 2 degrees, namely the difference between the chilled water supply water temperature set value and the wet bulb temperature is maintained to be 5 degrees, and further energy can be saved for the data center. By analogy, if the outdoor wet bulb temperature is further reduced and the difference value is increased, deep energy saving can be realized by reducing the supply water temperature of the chilled water and the outlet air temperature of the air conditioner.
Step S1043, determining that the target cooling amplitude is zero.
Specifically, if the target cooling amplitude is zero, it means that the chilled water supply water temperature setting value and the air conditioner outlet air temperature are not allowed to be further reduced.
In an optional embodiment, in step S106, the controlling the chilled water supply water temperature setting value to reduce the target cooling amplitude specifically includes the following steps:
and sending a cooling instruction containing a target cooling amplitude to the refrigerating station control system, so that the refrigerating station control system adjusts the rotating speed of a fan of the cooling tower and the rotating speed of the water pump based on the cooling instruction, and the target cooling amplitude is reduced by the chilled water supply water temperature set value.
As can be seen from the above description, in the embodiment of the present invention, since the air conditioner in the data center is connected to the moving-ring monitoring system, and the supply water temperature of the cooling water is controlled by the refrigeration station monitoring system, once the DCIM system determines the target cooling amplitude, the DCIM system needs to send a cooling instruction including the target cooling amplitude to the moving-ring monitoring system, so that the outlet air temperature of the air conditioner decreases the target cooling amplitude; on the other hand, a cooling instruction containing a target cooling amplitude is sent to the refrigerating station control system, so that the refrigerating station control system adjusts the rotating speed of a cooling tower fan and the rotating speed of a water pump (including a refrigerating water pump and a cooling water pump) based on the cooling instruction, and controls a water supply temperature set value of the refrigerated water to reduce the target cooling amplitude by adjusting the water outlet temperature of the cooling tower.
In an alternative embodiment, the method of the present invention further comprises the following:
and if the duration of the wet bulb temperature not greater than the preset temperature meets the preset time condition, controlling the refrigeration mode of the data center refrigeration system to be switched to complete natural cooling.
The temperature control method for energy saving of the data center provided by the embodiment of the invention is an improvement on a refrigeration mode of complete natural cooling, the refrigeration station monitoring system reports the wet bulb temperature detected by the outdoor wet bulb temperature sensor to the DCIM system in real time, and if the DCIM system determines that the duration of the wet bulb temperature not greater than the preset temperature meets the preset time condition, the refrigeration mode of the refrigeration system of the data center is controlled to be switched to the complete natural cooling.
For convenience of understanding, the following example illustrates that the design temperature of the chilled water supply and return water is 13/18 ℃, and if the outdoor wet bulb temperature is less than or equal to 8 ℃ and lasts for more than 1 hour, the data center refrigeration system is controlled to be switched to a complete natural cooling mode; when the outdoor wet bulb temperature is in the range of 9-14 ℃ and lasts for more than 1h, controlling the data center refrigerating system to switch to a partial natural cooling mode; and when the outdoor wet bulb temperature is more than or equal to 15 ℃ and lasts for more than 1h, controlling the data center refrigerating system to switch to a mechanical refrigerating mode.
In summary, the embodiment of the present invention provides a temperature control method for energy saving in a data center, which considers that the energy consumption of IT equipment is the largest for the data center, so in winter, an outdoor low-temperature natural cold source can be fully utilized to reduce the supply water temperature of chilled water and reduce the outlet air temperature of an air conditioner in the data center, that is, the inlet air temperature of the IT equipment is reduced to reduce the energy consumption of the IT equipment, and meanwhile, the temperature is reduced, and the energy consumption of the air conditioner is also reduced, thereby reducing the energy consumption of the data center to the greatest extent. By the method, the data center can be more energy-saving only by changing the software control logic of the DCIM system on the premise that the hardware of the existing refrigerating system is kept unchanged, so that the operation cost of the data center is further reduced, and the higher energy-saving requirement is met.
