Abstract

A refrigerating machine comprising a refrigeration system, a chamber (1) to be refrigerated, a freezing-defrosting subchamber (2), a fan (3) with which the air of the chamber to be refrigerated is pushed and made to circulate through the freezing-defrosting subchamber (2), which is provided with a thermoelectric Peltier-effect refrigerating device (4), whose normally warm part is in contact with evaporator of the refrigeration assembly and whose normally cold part is combined with the freezing-defrosting surface (6), and wherein the electric power source is provided with a switching and adjustment assembly (5) by means of which the surface (6) is switched from cold to warm and its temperature is adjusted.
