A ceiling fan is a type of fan installed in the ceiling that promotes air circulation, ensuring that the air in the room is not stagnant. The motor speed of a ceiling fan is lower than that of ordinary fans on the market, but it has greater torque. When in use, it generally has two rotation functions: forward and reverse:

● Forward rotation: Rotates counterclockwise from bottom to top. This can be used with cool air in summer. The downward airflow generated strengthens the circulation of cool air in the room and effectively reduces the temperature, improving the effect of air conditioning.

● Reverse rotation: Rotates clockwise from bottom to top. The upward airflow produced allows for effective convection of indoor air. When used with heating in winter, it can draw warm air upward, effectively improving the indoor temperature.
