REFRIGERATOR Russian patent published in 1997 - IPC

FIELD: cryogenic engineering. SUBSTANCE: refrigerator has units 1 and 2 with members made from energy transforming working medium, source 3 for creating electric field, heat absorber 4, heat transfer units 5 and 6 and blower 7. Inner surface of housing washed with liquid heat-transfer agent 12 is provided with metal coat made in form of strips 13 regularly applied lengthwise. Heat-transfer agent is pumped during half-cycle through clearances between members of unit 1 from which field is removed and their temperature drops due to electrocaloric effect. Then flow cooled in unit is directed to heat absorber 4 where heat is taken from object being cooled and then it is directed to unit 2 on whose members field is applied where it is heated. Heat is removed from cycle to surrounding medium by means of heat-transfer unit 6. During next half-cycle field is removed from members of unit 2 and is applied to members of unit 1, heat-transfer agent is pumped in opposite direction and heat is removed in heat-transfer unit 5. EFFECT: enhanced efficiency. 3 dwg , 1 tbl
