Control system and method for data center cooling

Abstract

The invention provides a control system and method for cooling of a data center. Wherein, the system includes: a plurality of servers; a plurality of first temperature sensors, respectively installed at the air inlets of the plurality of servers, for real-time detection of the inlet air temperature of the plurality of servers; a controller, for receiving the plurality of first The detected temperature sent by the temperature sensor is used to calculate the average temperature in the data center according to the detected temperature, and to generate control instructions according to the average temperature in the data center; and the air conditioner is used to receive the control instructions sent by the controller and adjust the air conditioner according to the control instructions working mode. The system in the embodiment of the present invention can avoid overcooling caused by too cautious cooling control strategy, or local server overheating caused by too aggressive cooling control strategy, and greatly reduce Cooling energy consumption and service failure rates.

Description

Technical field [0001] The invention relates to the field of computer technology, in particular to a control system and method for data center refrigeration. Background technique [0002] The purpose of data center construction is to provide a good operating environment for the servers stored in the data center. Specifically, from the perspective of ensuring the reliability of the server temperature, the cooling system of the data center is to meet the server's heat dissipation requirements. The design of the cooling system is to ensure a certain amount of air intake and air temperature, so that the components inside the server can meet An indicator of the reliability of the server temperature. Therefore, the goal of the design of the refrigeration system in the data center is to ensure that the temperature of the cold aisle in the data center can be stabilized within a certain range, and the air supply volume can reach a certain index. [0003] At present, the data center refrig...

Problems solved by technology

However, due to the influence of various factors, such as the specific layout of the computer room, the actual power consumption of the server, or the location of the server, the temperature inside the data center is not uniform.

Therefore, only a limited number of temperature sensors in the prior art cannot accurately reflect the internal temperature distribution of the data center, that is to say, the use of a limited number of temperature sensors cannot accurately reflect the fluctuation and change of the internal temperature of the data center

Therefore, when these temperature information is used as the control parameters of the cooling system, it is easy to cause over-cooling due to over-cautious cooling control strategy, resulting in waste of cooling energy consumption; The temperature in a local location is too high, which increases the probability of some servers malfunctioning due to high temperature

In addition, because the control parameters of the refrigeration system used are not precise enough, administrators often need to rely on manual experience to adjust the refrigeration control strategy

Therefore, not only the labor cost is wasted, but also the operation and maintenance efficiency of the refrigeration system is low

Furthermore, the existing cooling system and cooling control strategy are not suitable for the high-efficiency operation needs of larger and more complex data centers in the future
