Caeli, adiabatic air conditioning without gas or external block which consumes 5 times less energy

With heat waves becoming more and more frequent during the summer, resorting to air conditioning systems seems inevitable. In France, around 37% of homes were equipped with an air conditioner in 2022, compared to 20% in 2000. The use of this device has almost doubled in a few years, while according to researchers from the CNRM (National Center for Meteorological Research), the heat it emits further aggravates the problem of global warming. According to them, if the air conditioners used in Paris, for example, were to double by 2030, the temperature would increase by 2°C in the capital. These are devices that consume electricity, pollute and heat the outside air. This is what pushed the French start-up, Caeli Énergie, to develop technology based on an evaporation system that does not use energy.

A technology based on adiabatic cooling

Unlike conventional air conditioners operating with refrigerant gases, the air conditioner developed by Caeli Énergie is based on adiabatic dew point cooling technology. It uses the phenomenon of water evaporation to cool the flow of air extracted from the building and that blown into the room. “ Our technology is based on a natural process. When water changes from a liquid to a gaseous state, it produces cold. It is this principle that we extrapolate “, explain Rémi Pérony, co-founder and CEO of the start-up. According to him, the biggest advantage of this air conditioner is that the air it expels outside is cooler than the air it draws in. Furthermore, the higher the outside temperature, the more effective the cooling. It is important to note that for optimal efficiency, Caeli Énergie has focused on ultra-thin plates with an integrated capillary structure and an evapo-exchanger architecture.

An efficient and environmentally friendly air conditioner

This innovative air conditioning system has been designed to be both efficient and environmentally friendly. The young company has largely used recycled and recyclable parts in its manufacturing, and thanks to adiabatic cooling technology, it is energy efficient. Compliant with F GAZ regulations, this system uses five times less energy than a conventional air conditioning system and its carbon footprint is reduced by 80%. In terms of performance, its cooling power is 2 kW and its COP is four times higher than that of a traditional air conditioner. Furthermore, thanks to its elegant and compact design, this device designed by Caeli Énergie can be installed both in living spaces and in work spaces.

Caeli Énergie, French manufacturing in the spotlight

Created in 2020 by Stéphane Lips And Rémi PéronyCaeli Energy is specialized in the manufacture of eco-responsible air conditioners. Since its creation, this start-up has intended to favor the French industrial ecosystem and eco-design. Moreover, its air conditioning system is entirely manufactured in Grenoble. Note that the company has raised funds in 2023 to achieve a specific objective, that of automating their lines in their 600 m² building and preparing the launch of their air conditioner on the market. For information, the price of the latter is between €2,500 and €3,200 excluding tax (installation included), and it can cool a room of 20 to 40 m², with a standard ceiling height of 2.5 m.
