Cooling Mechanism and EfficiencyĪs the air circulates, it creates an even distribution of heat/cold throughout the room. The space around the fan is filled with air from above it and further out to the sides of the fan because of the vacuum created by pushing the air down.Īs air is pulled in from the sides of the fan, it creates a vacuum there, which is filled with air from the lower portions of the room, which is how whole room air circulation is achieved with a ceiling fan in summer mode. This also forces the air already below the fan to move closer to the floor. So, the air around the fan is pushed down. This is how the blades push air into the area below the fan when in summer mode. When your hands meet, the fingers of your left hand should naturally slide down the palm of your right hand, following the downward direction of your lower arm. Move the ceiling fan blade, a.k.a, your right hand, towards your left hand (the air). Now, you need to “pitch” your right hand to a 45° angle so that the fingertips of your left hand are now in line with your palm. Your right hand is the ceiling fan blade and your left hand is the air. To understand how this works, hold your hands up so that your palms are facing down and your fingertips are facing each other. When a ceiling fan turns counterclockwise, the high part of the pitched blades will lead. This pushes air down and creates a downward stream of air. The direction the blades are moving should be clear from this angle.
To tell which direction your ceiling fan is turning, stand directly under the fan and look up, preferably while the ceiling fan is at a low speed so you can see the individual fan blades. When your ceiling fan is switched to summer mode, its blades will be turning counterclockwise. Was this helpful? Summer Mode Airflow Pattern
