FIELD: refrigeration engineering.
SUBSTANCE: refrigerator comprises generator, absorber provided with the connecting pipes for supplying and discharging solution, condenser, evaporator steam-lifting pump for lifting strong solution to the separator actuated by means of coolant supplied from the generator, pipe for steam-gas mixture, and steam duct with hydraulic valve gate. The refrigerator has additional steam-lifting pump with lifting pipe, additional separator, and additional steam duct with hydraulic valve gate. The absorber is provided with the additional tank. The steam space of the separator is connected with the lifting pipe of the additional steam-lifting pump whose bottom end is connected with the tank in the bottom part of the absorber, and top end is set into the steam space of the additional separator that is connected with the lifting pipe of the downstream additional steam-lifting pump whose bottom end is connected with the additional tank in the bottom part of the absorber, and top end is set into the steam space of the downstream additional separator connected with the steam space of the condenser. The liquid spaces of the additional separator and downstream additional separator are connected with the connecting pipe for supplying solution to the absorber.
EFFECT: reduced sizes.
