Abstract:
An absorption refrigerator incorporating:a circulating tube for circulating a heat medium;an outer tube disposed coaxially with a portion of an outer surface of said circulating tube;a refrigerant-spraying unit for spraying liquid refrigerant to the outer surface of said circulating tube in a chamber formed between said circulating tube and said outer tube; andan absorbing-solution-spraying unit for spraying absorbing solution which absorbs refrigerant to the inner surface of said outer tube in the chamber so that the heat medium which is circulated in said circulating tube is cooled by dint of evaporation of the liquid refrigerant sprayed to the outer surface of said circulating tube, and the absorbing solution sprayed to the inner surface of said outer tube absorbs steam of the refrigerant, said absorption refrigerator comprising:a refrigerant retainer for accumulating the liquid refrigerant which has not been evaporated despite spray of the liquid refrigerant from said refrigerant-spraying unit such that the liquid refrigerant is not mixed with the absorbing solution,a refrigerant-circulating passage serving as a passage through which the liquid refrigerant in said refrigerant retainer is circulated to said refrigerant-spraying unit; anda pump provided for said refrigerant-circulating passage and arranged to convey the liquid refrigerant to said refrigerant-spraying unit.
