Data center machine room precision air conditioner control method based on channel sensor feedback

Abstract

The invention relates to a data center machine room precision air conditioner control method based on channel sensor feedback. The method comprises the following steps that channel sensor data and precision air conditioner equipment data are acquired, whether a data abnormality condition exists or not is checked, and alarming is performed if the data abnormality condition exists; if the data abnormality condition not exists, whether the machine room air conditioner equipment is in a remote control mode or not is detected, if yes, whether sensors exceeding SLA exist in all channel sensors or not is checked based on the set machine room SLA standard, and if yes, control over the corresponding sensors is triggered and processed; or, when all the sensors are within the normal range, corresponding energy-saving control is started according to whether a fan is located at the lower limit or not. According to the technical scheme, compared with a control method for controlling the air outlet temperature and the air return temperature of a single air conditioner based on PID, the machine room air conditioner control method based on real-time sensor data feedback can achieve a good energy-saving effect by reducing the power of machine room air conditioner equipment on the basis of ensuring the stability of the machine room environment.

Description

technical field [0001] The invention relates to the technical field of energy efficiency management of a data center computer room, in particular to a precision air-conditioning control method for a data center computer room based on channel sensor feedback. Background technique [0002] The control optimization of the precision air conditioner in the computer room of the data center is a process in which the environment (channel temperature, humidity) in the computer room is kept stable while reducing energy consumption as much as possible by adjusting the precision air conditioner. [0003] The existing control methods are usually based on the PID control of the precision air conditioner itself to keep the temperature of the air outlet and return air of the precision air conditioner stable. This control method can meet the requirements of maintaining a stable environment in the computer room, but the set values ​​of the outlet air temperature and return air temperature nee...

AI Technical Summary

Problems solved by technology

This control method can meet the requirements of maintaining a stable environment in the computer room, but the set values ​​of the outlet air temperature and return air temperature need to be manually set, and there is no way to adjust the precision air conditioner in real time as the load of the IT equipment in the computer room changes.

[0004] Based on this control method, usually in the real data center operation, the operation and maintenance personnel will leave a certain amount of redundancy for the temperature setting value to deal with the fluctuation of IT equipment load. This part of the redundancy causes energy waste
