METHOD OF COOLING OBJECT BY MEANS OF CASCADE-TYPE THERMOELECTRIC BATTERY Russian patent published in 1999 - IPC

FIELD: refrigerating engineering; thermoelectric cooler; manufacture of domestic, industrial and commercial refrigerators and freezers, air-conditions, medical and special-purpose thermocooling and thermostating devices. SUBSTANCE: method is based on proportioned transfer of heat from object and from stage to state at supply of controllable direct current to terminals of battery at intermediate accumulation of heat in thermal accumulators. Removal of heat is started simultaneously in all stages of battery; changeover of stages for accumulation of heat at thermal accumulators is effected independently on basis of relationship of predetermined settings T_1set1, T_iacc and T_iset2; upper and lower limits of temperature settings are set depending on temperature required for object being cooled. Removal of heat is started from hot stage after which stages are switched on independently for active removal and accumulation of heat; colder stages are placed in heat removal mode after change-over of hotter to heat accumulation mode. EFFECT: enhanced efficiency. 3 cl, 3 dwg
