High temperatures They are not giving up this summer. Barely one heat wave disappeared before the next wave was already on the starting grid, ready to go. So, search Efficient cooling systems And if possible, being kind to the environment, became a priority. Also, if this is better As the temperature risesIt is almost a dream. And the best thing is that this dream seems to be a possible thing, if we look at RACU . systemDivided Scientists from the University of Cordoba under the project We area.
It’s a cooling system Take advantage of hot air To keep the interior of the building cool. This makes it the most popular solution under the temperatures we are seeing in this heat wave. Above all, given what has been seen, this will not be an isolated thing in the future.
It works by combining two air handling technologies: Wheel dryer and direct evaporative cooling. The latter, the most efficient in hot climates, is the one that allows you to take advantage of the heat for a cooling system. But what else do we know so far about this apt invention?
Cooling system that takes advantage of high temperatures
During these recent heat waves, we’ve seen that in many places temperatures seemed to be much higher than the indicated mercury. This is due to ecstasy in some places Air humidity evokes the sensation of heat.
It’s inconvenient for us to keep ourselves cool, which is why RACU has a drying wheel to start with, which is responsible for Remove moisture from the air. Subsequently, by indirect evaporative cooling, it performs a heat exchange with the outside air which allows the cooling of the air circulating inside the building. The result is a cooling system Which increases efficiency with temperature. a win win.
In fact, as described In a statement issued by the University of Cordobathe experimental results obtained show that “at 9 am, with an outside temperature of 25 ° C, the RACU system is able to cool the air to 16 ° C, while at 42 ° C at 6 pm it cools down to 17 ° C. together Low energy consumption“.
But where do you get the energy to do that? heat exchange? In general, cooling systems use polluting energy sources, such as gas or oil. However, in this case Hot water is used From a 100% renewable local network. Again, the heat is tapped to cool the rooms. Before this creativity, The ancient Romans were very proud.
Beyond heat waves
Of course, this cooling system is very effective in cold rooms during a heat wave. Moreover, it does so in a 100% renewable manner. But in fact, its advantages are much more than that.
First of all, we remove from the equation the use Cooling materialsWhich is considered highly polluting to the environment and hazardous to health in the event of leaks.
In addition, using only outside air, a Better ventilationVery useful in times of COVID-19.
And if all that wasn’t enough, it has been proven that Energy consumption RACU is four times smaller than the conventional cooling system. There are plenty of reasons to trust it, even though it is still in the beta stage. Obviously, facing the future we face, we need systems like this to help us mitigate the consequences of climate change. Of course all this without forgetting that nothing will be enough if we do not take action to stop it at the same time.
