[0022] The present invention is not limited by the following embodiments, and specific implementation methods can be determined based on the technical solution of the present invention and actual conditions.
[0023] The present invention will be further described below in conjunction with embodiments: Embodiment 1: As attached Figure 2 As shown, this embodiment provides an implementation method for realizing energy-saving transformation of a computer room based on CFD, comprising the following steps: S10: Collecting parameters of the on-site computer room, generating a first CFD flow model according to the parameters of the computer room, and obtaining a power usage efficiency value PUE under the first CFD flow model.
[0024] It is understandable that CFD (Computational Fluid Dynamics) is a computer simulation analysis software based on fluid dynamics. CFD software contains a large number of model libraries, such as air conditioning model library, cabinet model library, IT equipment model library and server model library, and each model contains relevant attribute parameters. In this step, the room parameters of the on-site computer room are first collected. The room parameters include cabinet size, cooling duct and server module, etc., which are used to construct CFD-related room parameters in the computer room, and the specific parameters are not limited.
[0025] In this embodiment, the parameters of the computer room are collected, a first CFD flow model of the on-site computer room is generated based on the CFD software, and the power usage efficiency value PUE under the first CFD flow model is obtained, that is, the corresponding power usage efficiency value PUE under the on-site computer room is obtained. For example, by constructing a 3D model of the data room, the temperature field distribution, airflow field distribution, pressure field distribution, and humidity field distribution of all equipment in the data room, including server modules, cabinet modules, air conditioning modules, etc., are simulated to obtain the first CFD flow model and the power usage efficiency value PUE under the above distribution conditions.
[0026] From this, the power usage efficiency value PUE of the on-site computer room before the transformation can be obtained.
[0027] S20: Acquire a pre-configured engineering transformation model, and transform the first CFD flow model according to the engineering transformation model to obtain a second CFD flow model after the transformation of the on-site computer room.
[0028] In this step, a pre-configured engineering transformation model is also obtained, wherein the engineering transformation model is an energy-saving solution transformation model constructed based on the computer room simulation model of the on-site computer room. For example, the engineering transformation model is used to perform one or more of the following energy-saving transformations on the first CFD flow model: closing cold / hot channels, sealing cabinet gaps, adjusting the opening of the air supply floor for precise air supply, and replacing a more efficient cold source, etc., without specific limitation.
[0029] It should be noted that the first CFD flow model can be directly transformed by using the engineering transformation model, so as to simulate the transformation result model of the on-site computer room. Therefore, in this step, after obtaining the pre-configured engineering transformation model, the engineering transformation model is introduced to transform the first CFD flow model corresponding to the on-site computer room to obtain the transformed second CFD flow model. Exemplary. For example, the transformed second CFD flow model is obtained, and the closed cold / hot channels, sealed cabinet gaps, air supply floor openings and cold sources corresponding to the second CFD flow model are changed compared with the first CFD flow model, and the temperature field distribution, airflow field distribution, pressure field distribution and humidity field distribution of the on-site computer room are obtained. The second CFD flow model is obtained.
[0030] That is to say, in this step, the pre-configured engineering transformation model can be used to simulate the engineering transformation of the on-site computer room, so as to obtain the CFD flow model of the on-site computer room after the transformation, recorded as the second CFD flow model, and obtain the power usage efficiency value PUE under the second CFD flow model. From then on, the power usage efficiency value PUE of the on-site computer room after the transformation can be obtained.
[0031] S30: Compare the power usage efficiency value PUE under the first CFD flow model and the power usage efficiency value PUE under the second CFD flow model.
[0032] S40: If the power usage efficiency value PUE under the second CFD flow model is less than the power usage efficiency value PUE under the first CFD flow model, outputting energy-saving solution information corresponding to the engineering transformation model.
[0033] In steps S30-S40, after obtaining the power usage efficiency value PUE under the first CFD flow model and the power usage efficiency value PUE under the second CFD flow model, that is, obtaining the power usage efficiency value PUE before the on-site computer room renovation and the power usage efficiency value PUE after the on-site computer room renovation, the difference between the two is compared. If the power usage efficiency value PUE under the second CFD flow model is less than the power usage efficiency value PUE under the first CFD flow model, it means that the power usage efficiency value PUE after the on-site computer room renovation is less than the power usage efficiency value PUE before the on-site computer room renovation, and energy-saving optimization of the data room can be achieved. Therefore, the energy-saving plan information corresponding to the current engineering renovation model is output.
[0034] For example, the energy-saving solution corresponding to the engineering transformation model is closed cold channel. Then, according to the engineering transformation model, after the computer room simulation model of the on-site computer room is transformed, the PUE value is obtained. If it is smaller than the original PUE value of the on-site computer room, it means that this engineering transformation is an optimized solution, and the energy-saving solution information of the "closed cold channel" is output.
[0035] The present invention provides a CFD-based implementation method for energy-saving transformation of a computer room, which can be applied to a computer room, such as a data room, which can also be understood as a data center. As an example, Figure 1 As shown, Figure 1 The schematic diagram of a typical data center is shown in FIG. 1 , which includes a plurality of cabinet modules 101, a plurality of server modules 102, a plurality of air conditioning modules 103 and a cooling duct module 104, wherein the cabinet module 101 is used to load the corresponding server module. In addition, the data center also includes other energy-saving structures, which are not listed here. It should also be noted that Figure 1 This is only a simple demonstration of the structure of a data room. The implementation method for realizing energy-saving transformation of a data room based on CFD provided in the embodiment of the present application can be applied to various small, large or extra-large data rooms, and can also be applied to other data rooms without specific limitation.
[0036] Taking the data room as an example, it should be understood that for large / super-large data centers, the current power usage efficiency values PUE of large and super-large data centers in China are 1.5 and 1.39 respectively, which are very different from those of internationally advanced data rooms. There is a lot of room for energy saving, and as the energy saving and PUE requirements of data rooms become more and more stringent, data rooms need to be transformed for energy saving. There is an urgent need for a technical means that can well guide the implementation of energy saving in the room. To solve this technical problem, the present invention provides an implementation method for energy-saving transformation of a room based on CFD to output the optimal energy-saving solution information.
[0037] In this embodiment, mature computer room renovation measures are introduced, and CFD technology is used to simulate the engineering renovation of the data computer room, including but not limited to the sealing of cold and hot channels, sealing and blocking of cabinet gaps, adjusting the opening of the air supply floor and other airflow organization adjustment conditions, as well as the introduction of more efficient cold sources and other optimization conditions. The PUE value before and after the renovation is calculated to guide the implementation of energy-saving renovation of the computer room and further implement energy saving in the computer room. It can effectively solve the problem of estimating the energy-saving effect before and after the renovation and the problem of estimating the economic efficiency of energy-saving means. The use of CFD simulation can have a definite result before the implementation of energy saving, reducing unnecessary capital investment in the project.
[0038] It is worth mentioning that Figure 1 The data room shown is only an example. In actual applications, the data room can be very large, including a large number of equipment and differences in layout. The energy-saving implementation and transformation of the data room is extremely important. Through the present invention, using a pre-configured engineering transformation model, the energy-saving plan information of the computer room can be easily and quickly obtained, and the computer room can be transformed according to the output energy-saving plan information. It can well guide the energy-saving implementation of the computer room, realize energy-saving optimization of the computer room, and optimize the energy-saving efficiency of the computer room. It has high application value.
[0039] It is also worth mentioning that for some old computer rooms, such as most underground air supply room cooling, which are application scenarios where energy saving is not possible due to their backward construction model, the output of energy-saving solutions can also be achieved through the embodiments of the present application.
[0040] Embodiment 2: As attached Figure 3 As shown, the implementation method of realizing energy-saving transformation of a computer room based on CFD provided in this embodiment also includes the following steps: S50: If the power usage efficiency value PUE under the second CFD flow model is greater than or equal to the power usage efficiency value PUE under the first CFD flow model, abandoning the engineering transformation model.
[0041] In this embodiment, if the power usage efficiency value PUE under the second CFD flow model is greater than or equal to the power usage efficiency value PUE under the first CFD flow model, it means that the power usage efficiency value PUE after the on-site computer room transformation is greater than or equal to the power usage efficiency value PUE before the on-site computer room transformation. At this time, it means that the energy-saving plan corresponding to the current engineering transformation model cannot achieve energy-saving optimization of the data room, and the engineering transformation model is abandoned.
[0042] Embodiment 3: As attached Figure 4 As shown, in an implementation method for realizing energy-saving transformation of a computer room based on CFD provided in this embodiment, before comparing the power usage efficiency value PUE under the first CFD flow model and the power usage efficiency value PUE under the second CFD flow model, the following steps are included: S101: According to a plurality of energy-saving transformation schemes corresponding to the engineering transformation model, the first CFD flow model is transformed respectively to obtain a plurality of second CFD flow models after transformation; S102: Iteratively calculate power usage efficiency values PUE of multiple modified second CFD flow models until the power usage efficiency value PUE under one of the modified second CFD flow models converges, and obtain the power usage efficiency value PUE under the converged second CFD flow model.
[0043] In order to further improve the accuracy of the PUE value comparison before and after the transformation, and the efficiency of outputting the optimal energy-saving solution information, in this embodiment, a variety of engineering transformation models are obtained, and each engineering transformation model corresponds to one or more energy-saving transformation solutions. As an example, the engineering transformation model is used to perform one or more of the following energy-saving transformations on the computer room simulation model: closing the cold / hot channels, sealing the gaps between cabinets, adjusting the opening of the air supply floor for precise air supply, and replacing a more efficient cold source. It should be noted that in addition to the above energy-saving transformation solution examples, there may be other energy-saving transformation solutions, such as opening the hot channel, etc., which are not specifically limited. Moreover, the energy-saving transformation solution can be used alone or in combination to transform the computer room simulation model. It can be selected according to the applicable conditions of the data room, which is not specifically limited.
[0044] Then, according to the various energy-saving transformation schemes corresponding to the engineering transformation model, the second CFD flow model corresponding to the on-site computer room is transformed respectively, and the power usage efficiency value PUE of the transformed second CFD flow model is iteratively calculated until the power usage efficiency value PUE under the transformed second CFD flow model is stable, that is, converged. Convergence means that the power usage efficiency value PUE under one of the second CFD flow models is found to be optimal. Therefore, the on-site computer room is transformed until the corresponding PUE value of the transformed computer room is stable, and the PUE value of the corresponding second CFD flow model after stabilization is used as the PUE value of the transformed second CFD flow model to participate in subsequent comparison calculations.
[0045] In this way, on the one hand, a stable PUE value can be obtained after the transformation. The PUE value at this time accurately reflects the optimal energy-saving effect after the transformation, thereby improving the accuracy of the comparison of the energy-saving effect and further ensuring the feasibility of the plan; on the other hand, due to the use of a variety of energy-saving transformation schemes corresponding to the engineering transformation model, the computer room simulation model corresponding to the on-site computer room is transformed separately, and the energy-saving effect of each of the multiple energy-saving transformation schemes or the combined energy-saving transformation schemes can be calculated at one time, which is conducive to more quickly determining the optimal energy-saving transformation scheme information and improving the efficiency of scheme processing.
[0046] Embodiment 4: In the implementation method of realizing energy-saving transformation of a computer room based on CFD provided in this embodiment, the first CFD flow model and the second CFD flow model after transformation both conform to the standard flow field distribution. In this embodiment, as described above, the distribution conditions of the on-site computer room before transformation include temperature field distribution, airflow field distribution, pressure field distribution and humidity field distribution. CFD can be used to simulate the above distribution conditions of the on-site computer room, i.e., the first CFD flow model. After introducing the engineering transformation model and iterative settlement of the transformation, the CFD flow model corresponding to the computer room model after the transformation, i.e., the second CFD flow model, can also simulate the distribution conditions of temperature field distribution, airflow field distribution, pressure field distribution and humidity field distribution, in order to improve the effectiveness of the energy-saving scheme. In this embodiment, the CFD flow models before and after the transformation need to conform to the standard flow field distribution, such as the distribution conditions of temperature field distribution, airflow field distribution, pressure field distribution and humidity field distribution, so as to further ensure the feasibility of the energy-saving output scheme.
[0047] It should be understood that the order of execution of the steps in the above embodiments does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the present invention.
[0048] Embodiment 5: As attached Figure 5As shown, this embodiment provides an information output device for realizing energy-saving transformation of a computer room based on CFD, which corresponds one-to-one with the implementation method for realizing energy-saving transformation of a computer room based on CFD in the above embodiment.

Specifically, if the power usage efficiency value PUE under the second CFD flow model is less than the power usage efficiency value PUE under the first CFD flow model, the energy-saving scheme information corresponding to the engineering transformation model is output; if the power usage efficiency value PUE under the second CFD flow model is greater than or equal to the power usage efficiency value PUE under the first CFD flow model, the engineering transformation model is abandoned.
[0049] Furthermore, the acquisition module can also be used to: transform the first CFD flow model according to a plurality of energy-saving transformation schemes corresponding to the engineering transformation model, and obtain a plurality of second CFD flow models after transformation; iteratively calculate the power utilization efficiency value PUE of the plurality of second CFD flow models after transformation until the power utilization efficiency value PUE under one of the second CFD flow models after transformation converges, and obtain the power utilization efficiency value PUE under the converged second CFD flow model.

By introducing mature computer room transformation measures, CFD technology is used to simulate the engineering transformation of a data computer room, including but not limited to the sealing of cold and hot channels, sealing and blocking of cabinet gaps, adjusting the opening of air supply floors and other air flow organization adjustment conditions, as well as the introduction of more efficient cold sources and other optimization condition changes. The PUE value before and after the transformation is calculated to guide the implementation of the energy-saving transformation of the computer room and further implement energy saving in the computer room.
