The preset valve adjusting model is trained in advance and used for generating the valve opening according to the intake air temperature and the exhaust air temperature, namely the valve opening is determined according to the air temperature difference between the exhaust air temperature and the intake air temperature.
The magnitude of the air temperature difference has a mapping relation with the valve opening, and the mapping relation can be limited according to actual needs, and is not specifically limited here.
Further, if the air temperature difference is smaller than or equal to the air temperature value of the air adjusting valve, whether the air temperature difference belongs to a preset temperature adjusting interval is further judged.

and determining the starting refrigeration quantity of the cooling tower fan corresponding to the temperature regulation grade according to the temperature regulation grade to which the air temperature difference belongs.
Here, when it is determined that the target threshold interval to which the air temperature difference value belongs is a preset temperature adjustment interval, a target adjustment strategy of the preset temperature adjustment interval corresponding to the air temperature difference value is generated; however, in a preset temperature regulation interval, different levels are divided according to the size of the air temperature difference, so that the temperature regulation level to which the air temperature difference belongs needs to be determined first, the inlet air temperature and the outlet air temperature are input into a temperature regulation model, the temperature regulation level to which the air temperature difference belongs is determined, and as each temperature regulation level corresponds to different cooling tower fan starting refrigeration quantities, the cooling tower fan starting refrigeration quantities corresponding to the temperature regulation level are determined according to the temperature regulation level to which the air temperature difference belongs.

The temperature adjusting model is trained and used for judging the temperature grade to which the temperature difference value belongs according to the exhaust temperature and the intake temperature and generating the starting number of the cooling tower fans of the temperature adjusting grade corresponding to the temperature difference value.
Further, the relationship between the cooling tower load and the number of cooling tower fans is as follows:
qi＝Qt×Nt
wherein qi is the cooling tower load; qt is the starting refrigerating capacity of a single cooling tower fan; nt is the number of cooling tower fan stands.
Illustratively, the exhaust temperature of the press A is 140 ℃, the inlet temperature is 40 ℃, the air temperature difference between the exhaust temperature and the inlet temperature is 100 ℃ and is less than the valve air temperature value 110 ℃, the target threshold interval to which the air temperature difference belongs is determined to be a preset temperature regulation interval, the exhaust temperature is 140 ℃ and the inlet temperature is 40 ℃ are input into a preset temperature regulation model, the temperature regulation grade of the air temperature difference is determined to be high, and the cooling tower fans corresponding to the high grades start the refrigerating quantity of 50.
