Abstract
A refrigerator is provided with a continuous length of capillary material that extends via an opening in the refrigerator wall into contact with an evaporator in an enclosed evaporator space and with an externally disposed condensor. A hygroscopic liquid is contained in the continuous length of capillary material for absorption of moisture in the evaporator space and for elimination of moisture outside the refrigerator wall. The two ends of the continuous length of capillary material are arranged in liquid-transmitting contact with each other so that the hygroscopic liquid flows in a closed circuit.
Claims7
A refrigerator, which comprises an external wall providing an enclosed evaporator space;
- an evaporator positioned in said space;
- a vertically disposed condensor arranged outside the refrigerator wall;
- a pair of openings formed in the refrigerator wall, said openings being respectively at the corresponding ends of the evaporator;
- a continuous length of capillary material extending past the evaporator in contact therewith, through one of said openings, and extending past the condensor in contact therewith;
- and a hygroscopic liquid contained in said continuous length of capillary material for absorption of moisture in said evaporator space and for elimination of moisture outside the refrigerator wall, said hygroscopic liquid having a melting temperature lower than the lowest temperature occurring adjacent the evaporator;
- the two ends of the continuous length of capillary material being in liquid-transmitting contact with each other so that the hygroscopic liquid flows in a closed circuit.
