Reducing electricity costs or keeping cool during the hot season can be achieved by strategically positioning fans in a room.
It is most effective to place your fan near a window. This is because the fan can pull in the cool air from outside during night-time or early morning hours.
Also, to cool a larger room, it is ideal to use here multiple fans to create a cross-breeze.
You should not forget that the function of a fan is not only to distribute cool air around the room but also to drive warm air out of the room.
For such purposes, an exhaust fan is quite beneficial, since it expels the warm air outside of the room. While the exhaust fans are at work pushing the hot air out, simultaneously, a standard fan should be used to circulate the cooler air.
In summary, the effectiveness of cooling a room with fans primarily relies on their strategic positioning. By using these simple yet effective techniques, you can keep your spaces cooler while saving on energy costs.
