FIELD: heating.
SUBSTANCE: method of obtaining cold can be used in domestic refrigerators, equipped with absorptive-diffusion cooling units (ADCU). The method lies in the feeding a strong solution into generator 1 through a steam-lift pump 3, operation with the help of vapour of the coolant from the generator at the level ∇a, which is higher than level ∇b of the discharge of the weak solution in absorber 7. Boiling of the strong solution is ensured in the generator in the clearance between the inner 10 and middle 9 cylinders due to the removal of heat from the heater 12 through the clearance between the heat container 11 and the inner cylinder, filled partially with the evaporated solution, obtained during the heating of the strong solution, in the process of which occurs the spillage of the boiling solution from the clearance between the inner and middle cylinders. After this the partially evaporated solution between the middle and intermediate 8 cylinders are directed to the clearance between the heat container and the inner cylinder, where the final evaporation of the solution takes place with it level higher than the level ∇a of the strong solution in the generator and not lower than the heat container. Weak solution obtained is directed to the cooled channel of the heat exchanger (in the clearance between the intermediate 8 and the outer 6 cylinders), which is connected to the line of the weak solution between the cavity of boiling partially evaporated solution (clearance between the heat container and the inner cylinder 10 and carbine 18 for removing the weak solution from the generator to the absorber).
EFFECT: daily power consumption is reduced.
