FIELD: cold production. SUBSTANCE: method includes evaporation of coolant from strong solution, condensation of coolant vapors and evaporation of liquid coolant. In the course of liquid coolant flowing-off in evaporator, it is collected into vessel provided in lower part of evaporator. From said vessel, liquid coolant is supplied by means of steam-lift pump to separator. Further-on, coolant is directed through hydraulic seal to inlet of additional evaporator. EFFECT: reduced metal content and dimensions of refrigerating unit. 5 cl, 1 dwg
