Discover how new technologies are revolutionizing the market, promising energy efficiency and sustainability to replace air conditioning

O air conditioning It is widely recognized as an effective solution to cope with hot climates, but high energy consumption is a persistent problem.

Companies around the world are developing new T de REFRIGERAÇAO that promise to replace air conditioning, focusing on energy efficiency and sustainability.

Discover four promising innovations that could eliminate the need for conventional air conditioning units, from the groundbreaking radiant ceiling to geothermal cooling systems.

Radiant ceiling: efficiency and sustainability

O radiant ceiling emerges as a promising alternative, using plates with tubes that circulate low-temperature water to cool or heat environments.

Working with the physics of thermal radiation, this technology distributes cold or heat evenly, resulting in lower energy consumption.

Besides energy saving, the radiant ceiling offers silent operation, discreet design and low maintenance requirements, making it ideal for application in buildings.

Caeli One: the Caeli Energie revolution

A Caeli Energy, a French startup, has developed the Caeli One, a system that promises to consume up to five times less energy than traditional air conditioners.

Using adiabatic cooling and water evaporation, this technology eliminates the need for refrigerant gas, reducing carbon emissions by 80%.

The product, which measures 2,5 meters in height, is capable of cooling areas of 20 to 40 square meters.

Although the initial cost varies between €2.500 and €3.000, the low energy consumption guarantees long-term savings.

Elastocaloric cooling: the innovation of the University of Hong Kong

Researchers from Hong Kong University are exploring the elastocaloric cooling, a system 48% more efficient than traditional air conditioners.

This method eliminates the use of refrigerant gas, using metal alloys that change temperature through mechanical force.

The innovation has potential not only for domestic refrigeration, but also for improving the performance of electric car batteries, as highlighted in the journal Nature Energy.

Underground air: USP’s geothermal system

A University of São Paulo (USP) developed a technology that takes advantage of fresh air from underground, which naturally remains cooler than the surface.

This geothermal system uses buried cables to cool the environment, reducing energy consumption by up to 60% in commercial buildings and hospitals.

Already implemented in countries such as Germany and Switzerland, the challenge in Brazil is to make the technology economically viable, according to the website canaltech.

These four innovations demonstrate how the future of REFRIGERAÇAO can be more sustainable and efficient.

With technologies like radiant ceilings and Caeli One, traditional air conditioning could soon become a thing of the past.

Ah, so in Brazil, it will take a century and a half, in terms of delay, we are champions, the people are just a detail.
