Temperature control method and system for air conditioner energy consumption optimization of large data center

Abstract

The invention provides a temperature control method for air conditioner energy consumption optimization of a large data center. The temperature control method comprises the following steps that S1, aset of central air conditioner system used for overall cooling and a plurality of air conditioner single machines used for local cooling are deployed in the large data center or a machine room; S2, aplurality of air temperature meters are installed at different positions of the large data center or machine room, and air temperature values of all the air temperature meters are transmitted to a temperature control unit every t minutes; and S3, the temperature control unit performs temperature control. The method has the beneficial effects that the scheme that a central air conditioning system is mainly deployed and a plurality of vertical cabinet type air conditioning single machines are used as auxiliary schemes is adopted for a large data center and a machine room, the central air conditioning system and the vertical cabinet type air conditioning single machines are automatically controlled through a designed intelligent algorithm, and machine room optimal air temperature control withenergy saving as the target is achieved; and the energy consumption is effectively reduced, and the optimal air conditioner energy-saving effect is achieved.

Description

technical field [0001] The invention relates to a temperature control method, in particular to a temperature control method and system for optimizing energy consumption of an air conditioner in a large data center. Background technique [0002] At present, data centers equipped with large computer clusters have become one of the main places for energy consumption. The physical cooling of the computer cluster is an important basis for its performance. High-power central air-conditioning is a common physical cooling method for large-scale computer clusters. Due to the unbalanced distribution of tasks among the servers in a large computer cluster, and the large difference in the consumption of computing resources by different tasks, in the conventional energy-saving control that pursues the minimization of central air-conditioning energy consumption, it is easy to occur in the actual large-scale computer room due to individual Serious problems such as high server temperature ...

Problems solved by technology

Due to the unbalanced distribution of tasks among the servers in a large computer cluster, and the large difference in the consumption of computing resources by different tasks, in the conventional energy-saving control that pursues the minimization of central air-conditioning energy consumption, it is easy to occur in the actual large-scale computer room due to individual Serious problems such as high server temperature affecting computing performance or even system downtime

On the contrary, the following situation is also prone to occur: In order to prevent the temperature of individual servers from being too high in the actual large-scale computer room, the central air conditioner maintains a low temperature control of the temperature, thus causing a large waste of energy consumption

[0003] In the traditional large-scale computer cluster central air-conditioning energy-saving scheme, due to the "global temperature control" attribute of the central air-conditioning and the large energy consumption corresponding to the unit temperature reduction, the temperature control based on the central air-conditioning large-scale computer room is not only inflexible, but also difficult to achieve Optimal energy-saving effect of air conditioning
