DOMESTIC REFRIGERATOR WITH PELTIER EFFECT, HEAT ACCUMULATORS AND EVAPORATIVE THERMOSYPHONS

摘要

The invention relates to refrigerating installations of which the operation is based on the combination of Peltier effect producer elements and thermosyphons with liquid-vapor phase change. Basically it is comprised of: 1) Refrigeration container; 2) Heat dissipator; 3) Closed and fluid-tight circuit containing a fluid which boils or evaporates in the hot focal point situated in the low zone and condenses in the high zone, and then returns due to the gravity action (evaporative thermosyphon); 4) Peltier effect elements (first step); 5) Thermosyphon which transports the heat to the cold faces of the Peltier effect pastilles of the first step; 6) Thermosyphon which exchanges the heat with the prior thermosyphon and transports said heat from the hot faces to the Peltier pastilles of the second step; 7) Peltier effect elements (second step). 8) Thermosyphon which transports the heat from the container at low temperature or at frozen food temperature to the cold faces of the Peltier plates of the second step. The four fluids can be water with various vacuum levels.
