Description
Technical Field
The invention relates to the field of data centers, in particular to a wind wall control system.

The fans are arranged on the cabinet to form a matrix called a wind wall, and the control of the rotating speed of the fans on the wind wall is called a wind wall control technology. The Air wall system generally adopts an Air Handling Unit (AHU) Air wall cooling technology, and comprises a cold channel group and a hot channel group. The cold channel group comprises a plurality of cold channels, and the hot channel group comprises a plurality of hot channels. The temperature of cold and hot passageway all need be in reasonable within range, and cold passageway is by adjusting water valve control temperature, and hot passageway is by fan control temperature, and cold and hot passageway all disposes temperature sensor for acquire cold and hot passageway's temperature. In consideration of energy conservation, when the temperature of a certain cold channel is lower, the opening degree of the corresponding regulating water valve can be reduced, and when the temperature is higher, the opening degree of the corresponding regulating water valve is increased. Similarly, when the temperature of a certain hot channel is lower, the opening degree of the corresponding fan can be reduced, and when the temperature is higher, the opening degree of the corresponding fan is increased. The specific adjusting method can adopt a PID mode.
However, this adjustment method for each channel only considers the factors of the channel itself, and does not consider the influence generated between adjacent channels, for example, when the water regulating valve or the fan of a certain channel is at the maximum opening, the temperature still cannot be adjusted within a reasonable range, and the conventional method is to alarm for the relevant personnel to handle. Therefore, if a plurality of channels have the problems in succession, on one hand, frequent alarming can increase the labor capacity, and on the other hand, the continuous and slow temperature drop can make the whole indoor temperature uneven, and the energy-saving effect is not good. Therefore, there is a need to improve the existing air wall temperature control method to further improve the energy saving effect.

In case the channels comprise cold and hot channels, Pi=0 denotes that channel i is a cold channel, Pi=1 indicates that channel i is a thermal channel. FiFor the load shedding lock-up period of the ith channel, FiIf > 0, it means that the load shedding lock of the duct i is maintained, that is, the opening degree of the thermostat of the duct i cannot be reduced, Fi=0, it indicates that the load shedding lock of the lane i is released, that is, the adjustment opening degree of the thermostat of the lane i can be decreased.
