高い電子冷却式冷蔵庫を提供することを目的とする。As is well known, an electronic cooling element is a heat pump that draws heat from a low-temperature portion to a high-temperature portion by using an electric current. The generation of heat or heat absorption is called the Peltier effect. Heat generation or heat absorption due to the Peltier effect has a so-called reversible phenomenon that is reversed when the direction of current is reversed. Conventionally, the heat absorption by the Peltier effect is used for the cooling means inside the closed container which is insulated and partitioned, but for the heat generation on the other side, the air-cooling radiating fins and water-cooling plate only dissipate heat as a heat sink and it is not effectively used,
The coefficient of performance remained low and efficiency was poor. An object of the present invention is to provide an electronically-cooled refrigerator having a high cooling efficiency by effectively utilizing heat generated as cooling means.

It rises through the rising passage 11 and reaches the separator 4. In the separator 4, the ammonia gas and the low-concentration aqueous ammonia solution that has released the ammonia gas are vertically separated. The lower low-concentration aqueous ammonia solution is separated from the separator 4 by gravity into the absorber 5.
And flows down the absorber 5 toward the pool 13. As for the upper ammonia gas, only the dried ammonia gas proceeds to the condenser 6. In the condenser 6, the ammonia gas receives the wind from the blower 19, is cooled and liquefied, and is evaporated.
Head for. Liquid ammonia is passed through a separate passage 17 in the condenser 7.
The hydrogen gas comes into contact with the hydrogen gas and passes through the heat insulating compartment 18 to rapidly vaporize the gas. Then, the ammonia gas reaches the absorber 5 via the space above the reservoir 13. In the absorber 5, the low-concentration aqueous ammonia flowing down into the reservoir 13 absorbs the ammonia gas returned from the evaporator 7 and becomes high-concentration aqueous ammonia. Since the reservoir 13 is in communication with the generator 3, the high-concentration aqueous ammonia returns to the generator 3 and repeats the circulation. This cooling operation is continued as the electronic cooling element 20 as the heating means 9 continues to operate.
