Multi-air-conditioner automatic control system and method of cold-hot channel separated machine room

Abstract

The invention discloses a multi-air-conditioner automatic control system and method of a cold-hot channel separated machine room. The system comprises a data acquisition and communication server, temperature collectors, a serial port extension module and a control unit. The temperature collectors are arranged in machine room cold channels correspondingly, and the data acquisition and communicationserver is further connected to air conditioner communication ports through the serial port extension module. The temperature collectors, the data acquisition and communication server and the serial port extension module are all connected with the control unit. Multiple temperature monitoring points are arranged in the cold-hot channel separated machine room according to the cold channels, the setting temperature, starting and stopping of air conditioners are remotely controlled dynamically and intelligently according to the method, and the purpose that the cold channel temperatures are increased to a target value is achieved; and fixed correlation and intelligent dynamic correlation between all the temperature points of the cold channels and the air conditioners are established, synergiccontrol over the multiple air conditioners of the whole machine room is achieved, and in addition, the amount of wasted energy caused by excessive refrigerating of the air conditioners after the coldchannels and hot channels of the machine room are separated can be decreased.

Description

technical field [0001] The invention relates to the technical field of air-conditioning and refrigeration in a machine room with cold and hot channels separated, in particular to a multi-air conditioner automatic control system and method for a machine room with separated cold and hot channels. Background technique [0002] The data center computer room has developed rapidly in China, among which there is basically an industry consensus on the air-conditioning cooling and air supply mode with the separation of cold and hot aisles. The main method is to close the cold aisle and send it directly into the server cabinet for heat dissipation. Due to the closed cold aisle, the utilization efficiency of the cold source is greatly improved, but it also brings a difficulty in the cooling adjustment of the air conditioner. The reason is that the cooling of the air conditioner is determined by detecting the return air temperature and comparing it with the set temperature. The air con...
