The advantage of the tower fan is that the air supply is soft, the wind frequency is high, and there is no dizziness, so it is very suitable for the elderly, young children, hospital wards and other people who need care. However, the tower fan "throws" the wind out through the turbine rotation, and in the narrow fuselage space, the air will inevitably collide and friction with the shell, so it is generally inferior to the table fan in terms of efficiency, and the noise will be greater. Therefore, the tower fan is mainly used as a supplement to air conditioning, the role is to speed up indoor air circulation, the effect of single use is general, and other circulation fans have a better cooling effect, so the tower fan is a more chicken choice.
