Air conditioner cooling tower group control method based on semi-closed space

The invention discloses an air conditioner cooling tower group control method based on a semi-closed space. The air conditioner cooling tower group control method comprises the following steps of (1) constructing an entity model; (2) performing grid division on the entity model to construct a grid model; (3) setting a model parameter and a variable parameter of value simulation air flow distribution; (4) presetting negative pressure of all cooling towers; (5) setting a boundary condition and an initial condition of calculation; (6) initializing calculation, and performing value simulation calculation by a finite volume method to obtain a value simulation calculation result; (7) extracting and counting air inlet volumes of all the cooling towers, when the calculated air inlet volumes are larger than a rated air inlet volume, reducing the preset negative pressure, and when the calculated air inlet volumes are smaller than the rated air inlet volume, increasing the preset negative pressure; (8) returning to the step (5), and when the calculated air inlet volumes are equal to the rated air inlet volume, entering step (9); (9) calculating pressure drop of the whole air flowing journey; (10) selecting the types of fans of the cooling towers. According to the method, non uniform distribution of the air inlet volumes of the cooling towers can be avoided, and the selection on the type of the fans of the cooling towers is facilitated.
