Airborne acoustical noise emission class
"A", totally silent
We obtain this result by optimising the electronic regulation, and thanks to the cold exchanger concieved in aluminium, and being full part of the minibar's cavity. Based on the Peltier effect, innovative technology also called thermoelectric, a physical phenomenon of heat movement with and electric current. The effect takes place in the different nature materials of high conductivity linked together by junctions. One of the junction gets cold when the other one gets hot. The cold produced is collected inside the minibar, and the heat is evacuated thanks to a radiator located at the back of the minibar.
Today, this technology is only used for minibars.
