A cluster control method for precision air conditioners in computer rooms

Abstract

The invention relates to a cluster control method for computer room precise air conditioners. The cluster control method includes the steps that a control host is arranged in multiple control regions, and at least one controlled air conditioner and at least two temperature probes are arranged in any controlled region; in each region, the temperature probes correspond to the controlled air conditioners, and when a temperature parameter collected by any of the temperature probes corresponding to the controlled air conditioners exceeds a certain upper limit threshold value for certain time, the corresponding controlled air conditioners are turned on; when the temperature parameters collected by all the temperature probes are below a certain lower limit threshold value for certain time, the corresponding controlled air conditioners are turned off. The control method can effectively reduce the starting frequency of a compressor and avoid frequent starting, and the air conditioners are in a fully closed state for most of time each day to save energy. The running time after single starting of the compressor is prolonged, the energy efficiency ratio is increased, and the service life is prolonged. Data will be transmitted to a far end in real time, and the air conditioners can be manually operated to run or shut down at the far end.

Description

technical field [0001] The invention relates to the field of air conditioner control, in particular to an air conditioner control method for a computer room, in particular to an industrial control communication system for energy-saving operation and maintenance management of a precision air conditioner in a computer room. Background technique [0002] At present, the control method for the operation of the air conditioner in the computer room generally adopts a single threshold method, that is, a threshold value is set. The temperature near the return air filter of the air conditioner is detected by the temperature sensing package of the air conditioner itself. When the ambient temperature reaches the set threshold value, the compressor starts cooling; when the ambient temperature is lower than the set threshold value, the air conditioner stops. Or switch to ventilation mode. The advantage of this method is that the ambient temperature can be stabilized near the set thresho...

AI Technical Summary

Problems solved by technology

The advantage of this method is that the ambient temperature can be stabilized near the set threshold, but the disadvantage is that the air conditioner starts too frequently and consumes a lot of power. Even if it is running in the ventilation mode, it still needs to consume 20-50W of power per hour, so this control method Has a large energy-saving space

At the same time, since the temperature-sensing probe does not have temperature and humidity reading display, and the remote end cannot view the temperature and humidity in an area, it is necessary to manually measure the temperature to know the actual temperature of the equipment room, channel, and cabinet.
