AI Technical Summary

Technical Problem

In large data center computer rooms, the cross-use of cold volume between room-level air conditioning groups and inter-column air conditioning groups leads to operational conflicts and high energy consumption.

Method used

By obtaining the temperature data of the column air conditioning group and room-level air conditioning group, as well as the data of the cold channel temperature and humidity sensor, the group control configuration method is determined, including the operating control parameters and modes of the air conditioning unit, and the air conditioning group is controlled to perform corresponding configurations to avoid conflicts.

Benefits of technology

It effectively avoids the cold volume conflict between air conditioners, improves the operation safety of the computer room, reduces energy consumption, and improves the efficiency of the air conditioner.

Abstract

The invention discloses a group control method and system for a multi-group machine room air conditioner group. The multi-group machine room air conditioner group comprises at least one room-level air conditioner group and at least one inter-column air conditioner group. Air supply temperature data collected by the inter-column air conditioner group, return air temperature data collected by the room-level air conditioner group and cold channel temperature and humidity values collected by a cold channel temperature and humidity sensor are obtained; the group control configuration mode of the multi-group machine room air conditioner group is determined according to one or more of the air supply temperature data, the air return temperature data and the cold channel temperature and humidity value; the group control configuration mode comprises an operation control parameter and an operation control mode; and the inter-column air conditioner group and / or the room-level air conditioner group are / is controlled to execute the group control configuration mode. According to the method, the corresponding group control configuration mode is determined according to the detected current environment state, so that high-energy-consumption events are avoided, the operation safety of the multi-group machine room air conditioner group is improved, the energy consumption is reduced, and the efficiency of the air conditioner is improved.
