Abstract:
A double separation absorption refrigeration system comprising:a first generator (G1) at a pressure Ph and a temperature .theta.m, and being in hydraulic connection to a refrigerant and solvent supply duct channel (1), a refrigerant outlet duct channel (2), and a refrigerant and solvent outlet duct channel (3);a second generator (G2) in hydraulic communication via duct channel (3) with said first generator, wherein the second generator is at a pressure Pk and a temperature .theta.i, wherein Pk is lower than Ph and .theta.i is lower than .theta.m, and wherein the second generator is in hydraulic connection with a refrigerant outlet duct channel (4) and a refrigerant outlet duct channel (8);a condenser (K2) in hydraulic communication via duct channel (2) with said first generator (G1), in hydraulic communication via duct channel (4) with said second generator (G2), and in hydraulic connection with outlet duct channel (5), wherein the condenser is at pressure Pk.sub.2 and a temperature of .theta., wherein Pk.sub.2 is greater than Pk but lower than Ph, and wherein temperature .theta. is lower than .theta.i;an evaporator (E) at a pressure Po and a temperature of .theta.o, wherein said evaporator is in hydraulic connection with condenser K2 via duct channel (5) and with outlet duct channel (6), wherein Po is lower than Pk, and wherein temperature .theta.o is lower than .theta.i;an absorber (A) at a pressure of approximately Po and a temperature .theta., wherein said absorber is in hydraulic connection with evaporator E via duct channel (6) and with outlet duct channel (1);a compression device (P) having an inlet side and an outlet side, said compression device being operatively located in the duct channel (1) and in hydraulic connection with absorber (A) on the inlet side and with generator (G1) on the outlet side; anda refrigerant and a solvent.
