The main function of the circulating fan is to make the cold air blown by the air conditioner circulate better indoors and make the cold air distribute more evenly, while the function of the air conditioner fan is to make the wind blown by the fan cool down through the ice crystals. These two functions are different. If you have to recommend it, only the circulating fan is recommended. The ice crystals of the air-conditioning fan will cool the air for a while, but it will increase the air humidity, and you may feel uncomfortable indoors for a long time.
