Refrigeration vs all technology
WebTherefore, scientists and engineers have begun in recent years to explore new technologies for cooling such as thermoelectric cooling [3], thermoacoustic refrigeration, absorption refrigeration [4,5], adsorption refrigeration [6]and magnetic refrigeration. WebThe Peltier Effect: Thermoelectric cooling, is a solid-state method of heat transfer through dissimilar semiconductor materials. It is also called “the Peltier Effect” after the French watchmaker who discovered the phenomenon in the early 19th century.
