In the embodiment, wind information collected by a weather station is obtained; then, simulating the operation condition of the cooling tower under different wind information by utilizing computational fluid dynamics to obtain a curve number table of the relation between the wind information and the airflow flow of the cooling tower; finally, the direction of the air exhaust cylinder is adjusted according to the current wind information and the curve number table, so that the problems that the fixed air exhaust cylinder cannot fully utilize the efficiency of wind on air flow, the air exhaust effect is poor and the like are solved.
Fig. 2 is a flowchart illustrating a curve table of a relationship between wind information and airflow rate of a cooling tower obtained by simulating operating conditions of the cooling tower under different wind information using computational fluid dynamics according to an embodiment of the present invention.
As shown in fig. 2, the simulation of the operation condition of the cooling tower under different wind information by using computational fluid dynamics to obtain a curve table of the relationship between the wind information and the airflow flow rate of the cooling tower includes steps S210 to S220:

Fig. 3 is a flowchart illustrating a first curve table of a relationship between wind information and airflow rate of a cooling tower obtained by simulating operating conditions of the cooling tower under different wind information by using computational fluid dynamics according to an embodiment of the present invention.
As shown in fig. 3, the simulating the operation condition of the cooling tower under different wind information by using computational fluid dynamics to obtain a first curve number table of the relationship between the wind information and the airflow flow rate of the cooling tower includes steps S310 to S320:
s310: and obtaining the airflow flow of the cooling tower according to the operation condition and the wind information of the cooling tower.

As shown in fig. 4, adjusting the direction of the exhaust duct according to the current wind information and the curve number table includes steps S410-S430:
s410: setting a wind speed threshold.
S420: and if the current wind speed mean value is larger than the wind speed threshold value, adjusting the direction of the exhaust cylinder to be the current wind direction mean value.
S430: if the current wind speed mean value is less than or equal to the wind speed threshold value, the direction of the air exhaust cylinder is kept unchanged.
In this embodiment, the current wind speed mean value is a wind speed average value in a previous period of time t at the current time, and the current wind direction mean value is a direction angle average value in the previous period of time t at the current time.
In the embodiment, the wind speed threshold is influenced by the installation position of the cooling tower, and if the installation place is spacious, the set value of the wind speed threshold is small; if the installation position space is narrow and is easily influenced by the building and instantaneous wind is generated, the set value of the wind speed threshold value is increased. The setting of the wind speed threshold value can reduce the influence of peripheral transient wind.
In this embodiment, when the wind speed is lower than the wind speed threshold value, the gain obtained by adjusting the direction of the exhaust duct is too small, and the adjustment of the direction of the exhaust duct is not performed at this time. Therefore, the air exhaust cylinder direction is adjusted or kept unchanged according to the relation between the current air speed and the air speed threshold value by setting the air speed threshold value, so that the effect of utilizing outdoor natural air more efficiently is achieved.
Fig. 5 is a second flowchart of adjusting the direction of the exhaust duct according to the current wind information and the curve number table according to the present invention in an embodiment.

s510: a wind speed duration threshold is set.
S520: and if the current wind speed duration is greater than the wind speed duration threshold, adjusting the direction of the exhaust cylinder to be the average value of the current wind direction.
S530: if the current wind speed duration is less than or equal to the wind speed duration threshold, the direction of the exhaust cylinder is kept unchanged.
In this embodiment, the average value of the current wind direction is an average value of the direction angles in the previous period of time t at the current time.
In this embodiment, the wind speed duration threshold is affected by the installation location of the cooling tower, and if the installation location is relatively open, the time threshold setting is relatively small. If the installation position space is narrow, easily influenced by the building, and instantaneous wind is generated, the time threshold value set value is increased. The setting of the time threshold can reduce the influence of peripheral transient wind.
In this embodiment, the direction of the exhaust duct is adjusted or kept unchanged according to the relationship between the current wind speed duration and the wind speed duration threshold by setting the wind speed duration threshold, so that frequent direction adjustment of the exhaust duct caused by accidental wind gusts is prevented.
Before adjusting the direction of the exhaust pipe according to the current wind information and the curve number table and the current wind information and the curve number table in step S130, the method further includes:
and adjusting the exhaust barrel to the initial direction according to the wind information collected by the weather station.

s610: and acquiring wind information acquired by the meteorological station in a current period of time.
S620: and calculating the average value of the wind directions collected by the weather station.
S630: and adjusting the exhaust barrel to the initial direction according to the average value of the wind directions.
In this embodiment, the wind direction mean value is the average value of the direction angles in the previous period t at the current time, and the initial direction is the wind direction mean value.
The embodiment of the invention firstly acquires wind information collected by a weather station; then, simulating the operation condition of the cooling tower under different wind information by utilizing computational fluid dynamics to obtain a curve number table of the relation between the wind information and the airflow flow of the cooling tower; finally, the direction of the air exhaust cylinder is adjusted according to the current wind information and the curve number table, so that the problems that the fixed air exhaust cylinder cannot fully utilize the efficiency of wind on air flow, the air exhaust effect is poor and the like are solved.
