As an efficient data center solution, intelligent computing rooms integrate a large number of high-performance servers and network equipment, which generate a lot of heat. Traditional refrigeration systems often use a unified cooling method, which is difficult to dynamically adjust according to the changes in heat load in different areas, resulting in high energy consumption, low efficiency, and even equipment failure due to local overheating.
[0003] In recent years, the development of artificial intelligence technology and Internet of Things technology has provided new possibilities for improving the energy efficiency of data centers. By integrating advanced sensor networks, big data analysis and machine learning algorithms, refined management and intelligent control of the data center environment can be achieved, thereby significantly reducing energy consumption and improving the operating efficiency of the refrigeration system; however, the current refrigeration system usually relies on manual experience or simple control algorithms for refrigeration control, which makes it difficult to achieve precise cooling control of different areas and cannot effectively cope with the dynamic changes of equipment loads in the computer room. Based on this, an intelligent refrigeration control system is proposed, which can monitor the thermal state of each area in the computer room in real time and dynamically adjust the refrigeration strategy to achieve efficient and energy-saving refrigeration management.

[0051] in, represents a positive number, , represents the normalization factor of the cable connection point, , represents the weighted sum of the number of cables at each connection point, Indicates the minimum cable density set, Indicates the maximum cable density set;
[0052] The weighted sum of the number of cables at each connection point is obtained by obtaining the mean of the equipment load conditions of the devices connected to each cable connection point to obtain the cable connection point equipment load mean data set. The weight of each cable connection point is obtained by calculating the proportion of the mean equipment load of each cable connection point in the sum of the data in the cable connection point equipment load mean data set, and then the weighted sum of the number of cables at each connection point is obtained.

Therefore, the mean value of the electrothermal parameters of all equipment in each embedded grid and the cable distribution density are calculated and weighted summed to obtain the heat dissipation impact value of each embedded grid; the electrothermal parameters of the equipment are obtained by weighted summation of the load state value and temperature change rate of the equipment in the computer room.
[0061] Figure 2 The intelligent refrigeration control method of the dynamic environment system of an intelligent computing room in this embodiment is shown, and the intelligent computing room partition flow chart is shown; a heat dissipation impact difference threshold is set, and the upper left corner embedded grid of the i-th preliminary intelligent computing room partition is recorded as the first initial traversal grid, and the surrounding embedded grids are traversed from the first initial traversal grid with an embedded grid size as the radius. Each time the traversal is performed, the mean value ahdi of the heat dissipation impact value of the newly added embedded grid is recorded, and the calculation formula is: ,in represents the heat dissipation impact value of the jth embedded grid traversed during the kth traversal, where k represents the number of traversals at this time; calculate the heat dissipation impact value of the first initial traversal grid and The absolute value of the difference is used to obtain the traversal heat dissipation impact difference value. When the traversal heat dissipation impact difference value is less than the heat dissipation impact difference threshold, the traversal continues.

The cables in the main road will generate a lot of heat, which will generate a lot of water vapor when confronted with the cold air. Therefore, this design can avoid the harm of excessive air humidity caused by unreasonable air outlet allocation.
