Centralized control method for precision machine room air-conditioner system

Abstract

Disclosed is a centralized control method for a precision machine room air-conditioner system. The method comprises the steps that (1) indoor temperature and the humidity are monitored in real time, and a mathematic model is adopted for starting one precision air conditioner once the temperature or the humidity exceeds the upper limit or the lower limit; (2) after a few periods of time, the temperature and the humidity are monitored again, and if the temperature and the humidity are within the stopping range, all the precision air conditioners are stopped; if the temperature and the humidity are not within the stopping range, the mathematic model is adopted for starting another precision air conditioner; (3) the step (2) is executed repeatedly until the temperature and the humidity are within the stopping range. According to the centralized control method, on the premise that safe and stable running of a machine room can be ensured, the starting and stopping frequency of one single air conditioner is reduced, the service life of the air-conditioner system is prolonged, the maintenance cost of the machine room is reduced, and the centralized control method has high economic value.

Description

technical field [0001] The invention belongs to the technical field of centralized control of air-conditioning systems, and in particular relates to a method for centralized control of precision air-conditioning systems in machine rooms. Background technique [0002] Generally, precision air conditioners are installed in the computer room to maintain a constant temperature and humidity in the computer room. Now the start and stop rules of the precision air conditioner are as follows: once the ambient temperature or humidity exceeds a reasonable range, it will start immediately, and the ambient temperature or humidity reaches the shutdown range immediately. closure. The disadvantage of this is the lack of a unified control system among multiple precision air conditioners, resulting in frequent start and stop of a single air conditioner. Since the life of the air conditioner is calculated according to the number of starts of the compressor, once it is started, the current wil...

The disadvantage of this is the lack of a unified control system among multiple precision air conditioners, resulting in frequent start and stop of a single air conditioner

Since the life of the air conditioner is calculated according to the number of starts of the compressor, once it is started, the current will impact once, and the life will be reduced once. Therefore, the life of the precision air conditioner is directly related to the number of starts and stops. Shorter service life, which increases the maintenance cost of the computer room
