Unmissable for summer: these are the inventions that have the same function as an air conditioner and save energy

With the summer high temperatures arrive They test millions of people. This extreme heat not only causes discomfort, but also overloads electrical systems and skyrockets energy rates. Faced with this scenario, many families are looking for alternatives that allow them to cool off without affecting their wallets or the environment.

Technology and innovation offer sustainable solutions that reduce the environmental impact and the energy consumptionreplacing the traditional air conditioning. Two of the most notable inventions are the system developed by the M.I.T. and the proposal of the French startup Caeli Energie, that promise to revolutionize domestic and commercial refrigeration.

What are the inventions that can replace air conditioning?

While conventional air conditioners consume large amounts of energy and release harmful refrigerant gases, these new technologies seek cool spaces more efficiently and sustainably. From evaporation-based systems to devices that take advantage of thermal insulation, these options are not only planet-friendly, but also more economical in the long run.

Caeli Energie

The French startup Caeli Energie is the designer of a cooling system based on adiabatic cooling technologyan alternative that uses the evaporation of water to reduce temperature. This innovative equipment consumes up to five times less energy than a conventional air conditioner and eliminates the need for refrigerant gases, reducing the carbon footprint by up to 80%.

The system works without external drives, which simplifies its installation. It draws in hot air from inside the building and cools it through the evaporation of water, returning fresh air to the environment. In addition, its efficiency increases as the outside temperature rises, achieving cooler spaces with a iMinimal impact on electricity consumption.

This device, with a power of 2 kW, It is ideal for areas between 20 and 40 square meters, such as offices, meeting rooms and private homes. Its design incorporates recyclable materials and requires fewer parts to operate, making it a more economical and sustainable option in the long term.

MIT Technology

He Massachusetts Institute of Technology (MIT) developed an innovative cooling system that combines radiant cooling, evaporation and thermal insulationmanaging to reduce the temperature up to 9.3 °C without the need for electricity. This device, reminiscent of solar panels due to its compact design, is made up of three key layers: a airgel which acts as a thermal insulator, a hydrogel which allows evaporation and a layer reflector that prevents heating from solar radiation.

Water evaporates from the hydrogel, dissipating heat through the airgel and infrared radiation. This process allows interiors to be cooled efficiently, even in hot, dry climates. Additionally, its low maintenance makes it a practical option: it requires attention every four days in extreme conditions or once a month in more humid environments.

This technology also has additional applications, such as extend food preservation in areas where electricity is limited. However, the high production cost of airgel represents a challenge for its widespread use, although research is being carried out to make its manufacture cheaper and expand its use.
