We have known for a long time how to heat food quickly using microwave ovens. On the other hand, it will have been necessary to wait until 2020 to be able to operate the reverse process and quickly refresh a bottle or a can.

Will this CES 2020 have seen the first model of a household appliance that is completely new today but which will become essential in a few years? The Juno Chiller looks (on paper anyway) very promising. Its simple concept is to be able to refresh liquids in just 1 to 2 minutes for cans (33 cl) and 5 minutes for larger bottles (750 ml).



From the front, the Juno Chiller looks like a 40 cm high black pentagon. If we look at it from the side, we realize that it is quite bulky since its depth reaches 33 cm for 20 cm wide. You therefore need a large enough work plan to accommodate it. The containers are inserted from the top into a cavity designed to accept any type of bottle. All you have to do is press one of the three buttons (red wine, white wine, personalized temperature) to start cooling, the progress of which is indicated by the LED on the front which gradually changes from red to blue. After a few minutes, the liquid is at the ideal tasting temperature.

The way the Juno Chiller lowers the temperature obviously has nothing to do with that of a traditional refrigerator, using a liquid to promote heat exchange; the drinks would be cooled far too slowly. Engineers use a principle of thermoelectricity known for a long time and called "Peltier effect", discovered in 1834 by a Spanish watchmaker passionate about physics, Jean Charles Athanase Peltier. "When an electric current passes through a junction connecting two conductors, an increase or a decrease in temperature is observed depending on the direction of the current, the quantity of heat released or absorbed being proportional to the intensity of the current", specifies the universalis.com online encyclopedia. Note that this phenomenon is already used in aerospace, organ transport and, closer to home, microcomputing to cool certain components.


Before joining the aisles of CES where it had its small success, the Juno Chiller express cooler had already gained some notoriety on Indiegogo, a crowdfunding site. It is still possible to pre-order it by paying 179 €, before it goes to 360 € at its launch, which should take place in August 2020 if we trust the page dedicated to the project.
