    Abstract: PURPOSE:To defrost quickly and uniformly in spite of the height of defrosted substance by a method wherein only first high-frequency generator is operated in case the height of the defrosted substance is lower than a reference value while first and second high-frequency generators are operated sequentially in case the height of the same is higher than the reference value. CONSTITUTION:A height detecting unit 1, detecting the height of the defrosted substance, is arranged in a part of the defrosting chamber formed by parti tioning a part of a cold storage chamber while the first and second high-fre quency generators 9, 11, oscillating in different high-frequencies, are provided in the refrigerator. The frequency of the first high-frequency generator 9 is set at higher frequency than the same of the second high-frequency generator 11 while a defrost control means, consisting of a comparison circuit 3, a timer circuit 8 and the like, operates only the generator 9 in case the height of the defrosted substance is lower than the reference value, however, the same means operates the generator 9 and the generator 11 sequentially in case the height of the same is higher than the refrence value. As a result, the substance to be defrosted may be defrosted quickly and uniformly in spite of the height of the same.

    Abstract: PURPOSE:To keep the evaporation dish from overflowing with water from defrosting by setting the evaporation dish on a high-temperature double pipe and by passing through the evaporation dish a part of a dilute solution pipe which connects a high- temperature double pipe to an absorber. CONSTITUTION:An evaporation dish 25 is set on a high-temperature double pipe 10 of an absorption cooling system 9 in a manner of effecting heat transfer. A part of a dilute solution pipe 26 which connects the outer pipe 20 of the high-temperature double pipe 10 to the top of an absorber 18 is passed through the evaporating dish 25. Thus the evaporation dish 25 is placed on the high-temperature double pipe 10 in a manner of a heat exchanger and the dilute solution pipe 26 connecting the high- temperature double pipe 10 to the absorber 18 is partly passed through the evaporation dish 25 so that the evaporation of the water from defrosting can be accelerated by virtue of the heat from the high-temperature double pipe 10 and also the heat from the dilute solution pipe 26. Inside the evaporation dish 25 placed on the high- temperature double pipe 10 in a manner of a heat exchanger, by forming ribs for making the water from defrosting stagnant on the high-temperature double pipe 10 the water from defrosting is made to be stagnant preferably in an excellent space in terms of transfer of heat from the high-temperature double pipe 10 inside the evaporation dish 25.
