ECOLOGICAL AIR CONDITIONING

The global rise in temperature has made it increasingly difficult to live with air conditioners. But did you know that air conditioning consumes a lot of energy and makes up for more than 25% of our energy bill?

Faced with this problem, solutions are born that are applied to reduce our cooling costs. Among them, we find “ecological air conditioning,” an air conditioner that consumes 90% less energy than traditional equipment, to be the most effective.

The famous Eco Cooler, a completely manual built system that is widely used in third world countries, is capable of reducing the temperature by up to 5° C and all without using any electricity, is a prime example of ecological air conditioning.

This article focuses on the forms of air conditioning that are more environmentally friendly and are ecological.

100% ecological air conditioning: reality or fiction?

Air conditioning equipment manufacturers have been working hard to optimize the use of air conditioning equipment for decades. And despite achieving great results, today there is no 100% ecological equipment or air conditioning system. But we must emphasize that there are air conditioners that are capable of achieving savings of up to 70% of energy consumption, and manufacturers are constantly working on their optimization. There are some that use solar energy for their operation, which makes them almost entirely ecological, but their effectiveness is certainly questionable.

How does ecological air conditioning work with solar energy?

Like most people, it sure is hard for you to understand how you can get cold from a heat source. This is possible, thanks to the absorption cooling technique. This technique allows for obtaining fresh air from the heat obtained through solar collectors.

What is the absorption cooling technique?

This technique works by means of the solar energy captured in thermal solar collectors that heat the water at high temperature (between 80 and 150º C). Then the absorption machine performs a thermochemical compression cycle and produces cold water necessary for air conditioning.

The cold water is used for heat exchange between two fluids, one refrigerant, and one absorbent. The most common is to use water as a refrigerant and a salt (lithium bromide) as an absorbent.

But what about the Eco Cooler? Do you know about it? How does this ecological air conditioner work?

In the outskirts of Bangladesh, a group of young engineers has developed a 100% eco-friendly home air conditioner. An air conditioner that doesn't need electricity to work! An exemplary invention is full of ingenuity. Eco cooler (the name of this invention) has been designed by a local company that works to find technological solutions that can be made available to the entire population.

Why have they invented a low-cost air conditioner?

In Bangladesh, people regularly face very hot seasons (temperature could rise up to 45°), the houses are made of sheet metal, and the temperature reaches unbearable heights. The idea was simple, but at the same time, very ambitious. Develop an efficient air conditioner with low-cost materials, if possible recycled and accessible to the population, efficient and easy to build. A few months later, they overcame the challenge: Eco cooler meets all these conditions.

Its functionality is very simple. To understand it, do this test: blow in your hand with your mouth wide open, you will feel the hot air. Alternatively, do the same exercise with your mouth almost closed, you'll feel the cold air. To lower the air temperature, Eco-cooler simply uses this pressure difference system.

Are ecological air conditioning systems something new?

No, the human being for approximately two decades knows the problem that air conditioning and heating systems present in homes. And it is for this reason that for a few years, solutions are being sought, that are more environmentally friendly, and that can be applied in most homes.

In fact, the first techniques of cooling and air conditioning were focused in an ecological way. If we go to the past, we can see that the Egyptians allowed large stones to cool at night in the desert and use them the next day in buildings to lower the temperature inside it.

On the other hand, did you know that in ancient India, mats of wet grass were hung on the doors and windows so that when air entered the temperature would decrease? In some palaces of the Muslim Empire, the walls were full of vegetation that was constantly sprayed with water so that evaporation caused the environment to cool? Humans have always kept in mind the idea of air conditioning the spaces, but in a responsible way that does not cause much impact on the environment.

Bio climatization: the best alternative

Bio climatization is a natural evaporative cooling system. Its operation is simple, similar to the sea breeze: the hot air from outside passes through filters that give moisture and cool the air, filtering it and reducing its temperature up to 11ºC less than outside. The result is a cold and refreshing breeze, which constantly renews the air of the house or premises.

It is not only environmentally friendly but also thanks to the evaporative air the end-user has the possibility of obtaining more advantages. From the point of view of comfort and health, it allows us to heat a home or premises generating fresh, filtered, and fresh air ventilation, eliminating odors, fumes, or dust.

In addition to this, we provide the environment with the level of humidity suitable for people's health while eliminating static electricity. But there are two other factors that are very interesting:

Energy savings of up to 80%

Undoubtedly, its greatest advantage is the 80% savings on energy bills compared to conventional compressor systems, since we can acclimatize up to 200m² of housing or premises with a maximum consumption of 1100W.

Continuous ventilation is achieved.

Thanks to the way these systems work, the air in the rooms constantly circulates and is constantly renewed, providing continuous ventilation and a pleasant environment inside your house.
