A Cooler Ceiling Fan Trick You Might Have Overlooked

ceiling fans are very good allies against heat. More and more people are deciding to use these gadgets instead of a regular air conditioner. There are blades only, with built-in lighting or with nothing at all. adaptable blades so we can change both its speed and direction of rotation. The latter is very important because it helps us use these fans both in winter and summer. This is very useful, but it is important to know the ideal direction of the blades at each time of year. Otherwise, instead of cooling, we can increase the temperature in the room even more.

Ceiling fans that do not have the ability to change the direction of rotation always have this ability. counter-clockwise. This is because they are only intended for summer use. You can’t go wrong.

On the other hand, if all of these parameters can be changed, you have to be careful. Some directly include what is known as winter mode and summer mode. So there is no room for error. But if we make changes manually, the direction should always be clockwise in winter and counterclockwise in summer.

Why is the direction of the ceiling fan blades so important?

The air layers in the room are distributed by temperature. The coldest and densest tends to stay at the bottom, while the hottest rises and stays closer to the ceiling. Ceiling fans are responsible for move these layerscreating a current in the room.

When its blades move counterclockwise, a downward flow is created. That is, hot air descends, takes the place of the cold air below and forces it move sideways. So the cold air that was stagnant moves and helps us cool down. If the blades also move quickly, we will notice this sensation more strongly.

On the other hand, in winter the opposite happens. The blades of the ceiling fan rotate clockwise. Thus, it generates updraftso that the cold air rises and displaces the hot air, which will be drawn along the ceiling and down the walls to warm us. In this case, it is better for the process to happen slowly, so the blades need to be slowed down.

What if I don’t have a fan?

It is not necessary to have a fan to create air flow in your home, although it obviously helps. If we cannot or do not want to spend money on one of these devices, the key to success is in window.

We can ventilate the house by opening them during early hours of the daywhen it is not too hot. Ideally, look for cross ventilation, where the air moves from high pressure areas to low pressure areasgenerating a current that helps cool the rooms. To do this, ideally, you should open the doors and windows located in completely opposite sides of the house.

If you can create a diagonal between one window and another, the air flow created will be much more optimized. Also, under no circumstances should you open the windows. It is recommended to open 20% of those that do not directly open onto the street, and 10% of those that open onto the street completely. In this way, the same amount of air comes out as comes in, since the outlet is larger than the inlet, and the speed increases, creating a good air flow.

Thanks to these tips, we may not have to resort to ceiling fans. But we can’t deny that they are very useful at this time of year. If you decide to get one, be sure to check that the blades rotate in the appropriate direction.
