(54) INSTALLATIONS are batted; in the absorber 8. At the same time, the bromide-lithium solution in the absorber 8 is cooled with a boiling refrigerant in the evaporator 4. The strong bromic-lithium solution from the regenerator 2 is directed through the pipe 9 through the air heat exchanger 10 to the absorber 7, then through the heat exchanger 11 and the cooler 12 to the absorber 8 The resulting weak bromine-lithium solution is supplied by a pump 13 to a regenerator. In order to obtain a cold at a level of negative temperatures, a strong aqueous brine is fed to the evaporator by pump 14. At the same time, the ice melts at a reasonable temperature to obtain a weak saline solution. The cold is utilized by a coolant circulating through pipes 15. A weak salt solution is used by the working fluid in an auxiliary absorption cycle, in which VOLU is extracted and a strong salt solution is obtained. For this, weak saline solution is directed by pump 16 through teplo1 (ennik 17 and cooler. 12 in regener p 18. Obtained in regenerator 18 / water through nozzle 19 is fed to evaporator 6. Cold crystalline salt solution is used for crystallization of refrigerant in evaporator b after the heat exchanger 17 is partially passed through plate heat exchange elements 20. In some operating modes of the plant, heat exchange between solutions circulating through regenerators 2 and 18, which is carried out through the heat exchange surface 21, is possible. and vacuum in the evaporators 4, 6 and absorbers 7 and 8 use a vacuum pump 22 and a liquid separator 23. i.
