Cooling your home without warming the planet ! The past decade (2010-20) has been the hottest decade in history and January 2020 was the hottest January month on record globally. Unfortunately, this dangerous trend is likely to speed up in the upcoming years. As temperatures rise and heatwaves become more and more prevalent, the demand for space cooling is booming throughout the globe. The problem is that AC is accelerating climate change by leaking refrigerants into the atmosphere (which are strong greenhouse gases) and by relying on huge electricity needs to operate which are not neutral to global warming. Thus, the solution which is commonly used to withstand the summer heat in our homes is actually increasing the outside temperature : solution is now part of the problem. Caeli Energie is focusing on tackling the summer thermal discomfort in buildings without the need of refrigerants or any chemical and with high energy efficiency : The solution we have developed is a low footprint Air Conditioner for residential application based on an innovative thermodynamic cycle and a high-performance heat-exchanger. Using the latent heat of water, our technology lowers the air temperature by extracting heat from hot air and exchanging it to evaporating water. . Our solution is an indirect adiabatic cooler with a wet bulb efficacity reaching more 100%. The physical principle is inspired by nature: it is really close to the thermoregulation principle used by some mammals to control their own temperature. We have copied the phenomenon and we apply it to thermal comfort in building after having enhanced its efficiency and improved its housing integration. Compared to traditional vapor compression AC systems : Our energy efficiency is 3 times better ; We do not use any pollutant refrigerant ; We do not require any external unit.
