While the heat waves transform our homes into real furnaces, the temptation to push air conditioning is large. However, a simple, economical and surprisingly effective solution comes from Spain to cross summer in the fridge. Forget the exploding electricity bills, here is the tip of the frozen water bottle to refresh a room without air conditioning.

Far from being a simple gadget, this method is based on a basic physical principle. The idea is to use one or Several plastic water bottles Like ice blocks to cool the ambient air. It is a particularly popular technique in regions as in the South of Spain where temperatures can happily exceed 40 degrees in the shade.

The implementation is of childish simplicity: fill a plastic bottle with three -quarter water (never to the brim, because the water expands by freezing and could burst the bottle) And place it in the freezer.

Once the water has been solidified, position the bottle in height in the roomon a shelf for example, taking care to place a container below to collect condensation water.

By forming around the ice bottle, the colder, denser air will “fall” towards the ground, pushing the hot air to climb. The latter will in turn come into contact with the bottle, cool, and will go back down, creating a slow cycle that lowers the temperature.

Bonus tip: Transform your fan into auxiliary air conditioner

To increase the effectiveness of the frozen bottle, the best known improvement is to combine it with a simple fan. The method, sometimes nicknamed the “fan-glaçon”, radically transforms the feeling of freshness.

Place your frozen water bottle just in front of the fan blades. By blowing on the ice surface, the device will no longer be content to brew hot air; he will actively diffuse the cooled air throughout the room.

This physical principle of thermal transfer offers a Immediate feeling of freshness. The blown air passes on the ice, cools, then is propelled into the room, creating an effect close to a rudimentary air conditioner.

However, we must remain realistic: the effect is especially sensitive in a restricted space And lasts the time that the ice starts to melt. It is therefore a perfect solution for a room or an office, but it will not replace a real air conditioner in a large living room.

Finally, remember that the electricity consumption of a fan is less compared to air conditioning.

A global strategy for housing that remains fresh

This tip is an excellent complement, but its effectiveness is maximum when it fits into a broader strategy of combating heat.

The first essential reflex is to block heat before it enters. To do this, keep the shutters, blinds and curtains closed during the hottest hours of the day, especially on the facades exposed to the sun. The choice of light colors for these protections can also help to think about light and heat.

At night, when the outside temperature finally drops, it’s the opposite moment: you have to draft By opening large windows to evacuate the heat accumulated in the walls and furniture.

Also remember to limit internal heat sources: avoid using your oven or cooking plates and completely turn off electronic devices that give up heat even in standby.

Finally, another tip is to Hang wet sheets in front of a ajar window. By evaporating, water absorbs heat from the incoming air, a principle of evaporation cooling already used by the Romans.
