Problems solved by technology
When the excessive season comes, the air is dry and the dew point temperature is low. The temperature of the air outlet from the cooling tower reaches the dew point and enters the foggy area, forming white mist, which looks like white smoke caused by a fire. Some residents do not understand and mistake it for a fire, and some even call the police cause unnecessary panic and trouble

Embodiment Construction
[0015] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.
[0016] Such as figure 1 As shown, it is a cooling tower air outlet anti-fog method based on firefly algorithm energy optimization, which includes the following steps:
[0017] Step 1 Collect the cooling tower outlet air temperature, relative humidity, and wind speed, and monitor the ambient dry bulb temperature, relative humidity, and wind speed around the air outlet;
[0018] Step 2 Calculate the temperature and absolute humidity of the mixed air. If the saturated humidity of the mixed air is higher than the absolute humidity, anti-fog treatment will not be performed; if the mixed saturated humidity is lower than the absolute humidity, start the supplementary air device to increase the air supply volume of the cold air;
[0019] In step 3, the mu...

The invention discloses a cooling tower outlet air anti-fogging method of energy consumption optimization based on a firefly algorithm. The cooling tower outlet air anti-fogging method comprises the steps that the temperature, the relative humidity and the wind speed of cooling tower outlet air and the dry-bulb temperature, the relative humidity and the wind speed of the surrounding environment of an air outlet are collected, and the temperature and the absolute humidity of mixed gas are calculated; if the saturation humidity after mixing is lower than the absolute humidity, an air supply device is started to increase the cold air supply quantity; and a cold air supply quantity value is obtained for optimizing energy consumption, a temperature saturation difference value and a dew point temperature difference value through the firefly algorithm in a multi-objective mode, and cooling tower outlet air anti-fogging at low energy consumption is finally achieved. By adoption of the method, a mathematic model is established according to a cooling tower outlet air fogging mechanism, only the dry-bulb temperatures, the relative humidities and the wind speeds of the cooling tower outlet air and the surrounding environment of the cooling tower outlet air need to be collected, the cold air supply quantity is automatically optimized, cooling tower outlet air anti-fogging at lower energy consumption can be achieved, and the thermal performance of a cooling tower is ensured.
Description
technical field [0001] The invention relates to a cooling tower air outlet anti-fog method, in particular to an intelligent algorithm-based cooling tower air outlet anti-fog method. Background technique [0002] Cooling towers use the heat and mass transfer process between air and water to take away waste heat from industrial or air-conditioning systems and become an important part of the air-conditioning system. A cooling tower in which hot water uses coils and cold air to dissipate heat through heat transfer is called a dry cooling tower; a cooling tower that directly sprays hot water on the filler and allows the air and water droplets to directly contact and dissipate heat is called a wet cooling tower. The dry cooling tower can eliminate the loss of circulating water, but the cooling efficiency is low, and the cooling limit is the air dry bulb temperature; the wet cooling tower has high cooling efficiency, the cooling limit is the air wet bulb temperature, and the coolin...
