Embodiment Construction
[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0028] see Figure 1~2 , in the embodiment of the present invention, based on 5 Jialitu M-816 air-cooled units, 3 cold aisles, and 4 hot aisles, 3*10 cold aisle temperature points are set for implementation, and ten temperature points are set in each cold aisle The temperature collector 3 is used to monitor the temperature in the cold aisle in real time. Each temperature collector 3 is a temperature monitoring point. The temperature collector 3 is connected to...

The invention discloses a multi-air conditioner automatic control system and method for separating cold and hot aisles from a computer room. The system includes a data acquisition and communication server, a temperature collector, a serial port expansion module and a control unit, wherein the temperature collector is arranged in the computer room. In the cold aisle, the data acquisition and communication server is also connected to the communication port of the air conditioner through the serial port expansion module, and the temperature collector, the data acquisition and communication server, and the serial port expansion module are all connected to the control unit. In the computer room where the cold and hot aisles are separated, a plurality of temperature monitoring points are distributed according to the cold aisle. According to the present invention, the set temperature of the air conditioner and the switch machine are dynamically and intelligently controlled remotely, so as to achieve the method of raising the temperature of the cold aisle to the target value; establishing a cold aisle The fixed correlation and intelligent dynamic correlation between each temperature point and each air conditioner can realize the coordinated control of multiple air conditioners in the overall computer room, and can reduce the amount of energy waste caused by excessive cooling of the air conditioner after the separation of cold and hot aisles in the computer room.
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 an automatic control system and method for multiple air conditioners in 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 method with the separation of cold and hot channels. 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. ...
