The invention relates to absorption refrigerating machines with jet apparatus. An absorption refrigerating machine with jet apparatus includes connected in sequence a desorber with lines of low-concentration liquid solution of refrigerant and absorbent, concentrated liquid solution of refrigerant and absorbent, vapor-like high pressure mixture of refrigerant and residual absorbent, condenser connected by its inlet to line of vapor-like high pressure mixture of refrigerant and residual absorbent and outlet through line of liquid refrigerant – to inlet of evaporator outlet of which is connected to inlet of absorber through line of low pressure refrigerant vapor, jet apparatus connected by its diffuser to inlet of absorber and by receiving chamber – to outlet of heat exchanger of solutions through line of low concentration liquid solution of refrigerant and absorbent inlet of which is connected to outlet of desorber connected by its inlet to outlet of heat exchanger of solutions through line of concentrated liquid solution of refrigerant and absorbent outlet of which is connected to outlet of absorber. The jet apparatus is arranged as condensation thermo-presser connected by its operation nozzle through line of low pressure refrigerant vapor to outlet of evaporator, and outlet of heat exchanger of solutions through line of low concentration liquid solution of refrigerant and absorbent is connected as well to inlet of absorber. At line of low pressure refrigerant vapor a evaporator thermo-presser is installed as well, with jet pump, those increase pressure of refrigerant, and vapor-liquid and vapor heat exchangers, vapor heater, liquid separator. The invention provides effective operation of jet apparatuses, increases coefficients of ejection of jet apparatuses, decreases heat load on desorber, this increases power efficiency of the machine. |
