What’s pushing cooling technology now, is the energy efficiency challenge. New standards will arrive soon, including A++++ energy class and innovative technologies, such as magnetecaloric, are not ready for large scale usage. i remember the day in which the design of new platform BM 60 was launched, here the words of the R&D; director: “We have to achive the energy consumption of this refrigerator lower then the lamp inside, that is switched on 100% of the time (holding the lamp on his hand). Moreover, don’t forget that due to the cost competitiveness, the final cost has not to be much different from the lamp (smiling). This implies that each engineer on the field of thermodynamics and fluidodynamics has the ambition to reach the best design available.
