In fact, there are great differences in the operating mechanism and principle of the fan and air cycle machine.1, the operating principle of the fanThe fan simply uses electromagnetic induction to make the blade rotate rapidly, so that the air in front of the fan flows quickly, and the fast flowing air passes through the human body, causing the surface of the human body to evaporate and absorb heat, thereby making the body feel cool. However, throughout the operation of the fan, the fan does not have a cooling effect on the indoor air. If the indoor temperature is high, the wind blown out is also high temperature. Conversely, the heat is released during the operation of the fan, causing the temperature to rise near the fan.2, the working principle of air circulation fanThe main function of the air circulation fan is to form a convective circulation of indoor air to achieve an equilibrium temperature effect with a reasonable air flow direction. Generally, it can not be used directly as a refrigerator. It is often used in conjunction with air conditioners to achieve rapid cooling and balance room temperature. It can also be used to circulate air inside and outside, allowing indoor and outdoor air to alternate.Therefore, the main function of the fan is to evaporate the body water to make people feel “cool”, while the air circulation fan is mainly aimed at the air flow to reach a room temperature balance.
