The genius invention that can cool rooms without using electricity in seconds

Air conditioning has become one of the great allies in the fight against the high temperatures of summer, which will reach 40 degrees in some areas of Spain. Faced with this scorching heat, many people often resort to these devices to stay cool, and they can find anything from a device that does not require an external device and saves money by spending five times less electricity to another device from Lidl that does not require installation. Now they have been joined by a genius 3D Printed Invention Cools Rooms Without Using Electricity.

Rameshwari Jonaledda, an architecture graduate from the Bartlett School of Architecture, University College London (UCL), came up with TerraMound. It’s about Innovative Eco Air Conditioning Eco-friendly, based on the design of a termite mound, made of clay, fully 3D printed and works without electricity. An invention whose creator wanted to redefine the design of devices currently used to cool homes and offices.

TerraMound was developed by a student. As part of a thesis project for a Master of Design degree“My main goal was to experiment with porous cells with simple surface geometries and explore the potential of high-surface geometries. These simple surfaces drive innovation in different fields, such as aerospace, medicine, or materials science,” Jonaledda explained on his LinkedIn account last March.

Works without electricity

Adiabatic or evaporative cooling air conditioners are not really new, there are currently other models such as: One cools the house by 4 degrees with minimal electricity consumption or another is also 3D printed. In fact, this technology comes from a very distant place, as it is believed to have been inherited from ancient Egypt and Persia; and with it what is being It is the use of the natural process of water evaporation to cool the air. Without the need to use electricity.

In the case of TerraMound, to develop this innovative eco-friendly air conditioner, its creator Explore the natural cooling mechanisms found in termite mounds.which thanks to its porous structure can effectively cool its internal compartments. The invention combines clay with triangular periodic minimum surface (TPMS) engineering; thus replicating “the complex structures found in nature.”

Jonnalagedda notes on the project website that his invention resembles a desktop cooling fan and is very simple to operate. A little water is poured from above and filters through the large surface of the ceramic. Taking advantage of the hygroscopic nature – the ability of some materials or substances to absorb moisture from the surrounding environment – ​​of clay, Evaporative cooling is facilitated..

This is accompanied by an amplified airflow that creates an innovative, compact cooling system. However, it should be noted that the TerraMound prototype is not a completely passive device, because inside, specifically at its base, it uses a battery-powered electric fan that generates the airflow needed to create this cooling effect. Although the real potential of this invention lies in the possibility of scaling up. Its concept and diversification of applications.

Thanks to its compact design, this air conditioner is electricity-free. It can also be used as a decorative object.Even by combining minimal surfaces with the freedom of 3D printing, it offers great customization and, according to its creator, can be used to create facade systems in buildings with efficient ventilation, air and heat control mechanisms, bioreceptive structures and even has potential in terms of energy capture.

3D printed

One of the main challenges Rameshwari Jonaledda faced when creating his invention was how to reproduce the complex shapes of termite mounds. To do this, the student turned to 3D printing and actually confirmed that Delta WASP printer is used. -Designed for printing dense liquid materials – red terracotta clay and white stone clay. After the first printing, each piece of this cooling tower was fired in a kiln to form the prototype.

Another interesting feature of this invention is that it has a modular design that allows it to be increased in height to customize it for different environments and improve its energy efficiency. It will also be possible to integrate small pieces into walls, Jonalgida explained. Regulate temperature, airflow and lightAs a proof of concept, the student printed prototypes of 3D desktop ceramics with different surface geometries and porosities.

“I’m excited about the idea of Continue exploring these engineering concepts.“Experimenting with different materials and exploring other available technologies to unleash their potential, especially in the field of large-scale 3D printing,” the student explained on LinkedIn. The innovative air conditioner could revolutionize the future of construction and architecture by providing the transition to buildings that “breathe, adapt and live in harmony with nature.”
