Control method for computer room air conditioner system

Abstract

The invention discloses a control method for a computer room air conditioner system. Environment data of a current moment are substituted into a predictive function to obtain a predictive temperature of a next moment of each monitoring point. By adopting an extrapolation method, a predictive temperature of a next moment of each monitoring point is obtained according to environment data of a previous period of the current moment, the obtained two predictive temperatures are subjected to weighted averaging, and after weighted averaging is conducted on the predictive temperatures of all the monitoring points, summarizing is conducted to obtain a summarization value. The air conditioner system is controlled in terms of the summarization value to adjust the temperature of the computer room. The adjusting speed of the temperature of the computer room is increased obviously, and the problems that for a traditional method, because the mounting position of a temperature sensor is inappropriate, the rapid-changing temperatures of the monitoring points cannot be obtained in time, and the air conditioner system cannot be controlled through the temperature data collected in real time, so that the temperature adjusting speed is low, and more seriously, a computer chip may be damaged, or energy consumption is high are solved.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning system control, and in particular relates to a control method for an air-conditioning system in a computer room. Background technique [0002] With the rapid development of computer technology, the scale of the computer room is gradually expanding, and the amount of information transmitted and stored by various electronic devices in the computer room continues to increase, resulting in a substantial increase in the power density and heat density in the computer room. This will seriously affect the service life of the equipment and the safety and reliability of operation. In order to meet the ever-increasing heat dissipation demand in the computer room, reduce the energy consumption of the computer room and improve the energy utilization rate, it is more and more important to optimize the air-conditioning control system to improve the operation efficiency of the air-conditioning.

AI Technical Summary

Problems solved by technology

The main problem with this method is that because the temperature sensor is far away from the main heat source computer in the computer room, when the temperature of a certain monitoring point (such as a certain computer) rises rapidly, the temperature sensor cannot quickly sense the monitoring point. Therefore, the temperature of the monitoring point cannot be quickly reduced; in addition, the traditional control method is generally based on the temperature of the monitoring point measured in real time. Since the temperature of the monitoring point at the next moment is not known, it cannot effectively reduce The temperature of the monitoring point

All of these may cause damage to the electronic equipment at the monitoring point

Sometimes in order to meet the needs of equipment safety, a larger computer room air-conditioning air supply volume and lower air supply temperature have to be adopted, which eventually leads to excessive energy consumption of the computer room air-conditioning system
