The invention relates to absorption refrigerating machine, in particular with re-circulation in absorber. An absorption refrigerating machine with re-circulation in absorber includes connected in sequence desorber with lines of low-concentration solution of refrigerant and absorbent, concentrated solution of refrigerant and absorbent, vapor of high pressure refrigerant, condenser connected by its inlet to line of high pressure refrigerant and by the outlet – to inlet of evaporator connected by the outlet to inlet of absorber to which jet apparatus is connected by diffuser, heat exchanger of solutions connected by its inlet through line of concentrated solution of refrigerant and absorbent to outlet of pump of concentrated solution of refrigerant and absorbent inlet of which is connected to outlet of absorber, outlet through line of concentrated solution of refrigerant and absorbent solution heat exchanger is connected to inlet of desorber and by inlet through line of low concentration solution of refrigerant and absorbent – to outlet of desorber. Jet apparatus is connected by its working nozzle to outlet of solution heat exchanger through line of low concentration solution of refrigerant and absorbent, and by receiving chamber – to outlet of absorber through line of concentrated solution of refrigerant and absorbent. The invention provides increase of power efficiency of refrigerating machine. |
