Abstract:
1. A method of improving a heating temperature of a heat pump comprising steps of: a dilute solution of an absorber (D 1 ) passing through a solution heat exchanger (G 1 ) and then entering a generator (A 1 ), and then heating the dilute solution by a residual heat medium flowing through the generator (A 1 ) for releasing a refrigerant vapor to provided to a condenser (B 1 ), a concentrated solution of the generator (A 1 ) flowing through a solution pump (E 1 ), the solution heat exchanger (G 1 ) and entering the absorber (D 1 ) for absorbing heat and being partially vaporized, and then entering a steam bleeding chamber ( 1 ), the steam bleeding chamber ( 1 ) releasing the refrigerant vapor to enter the condenser (B 1 ), the concentrated solution flowing through a new added solution pump ( 3 ), a new added solution heat exchanger ( 5 ) and then connecting a new added absorber ( 2 ), then the concentrated solution absorbing the refrigerant vapor came from the absorber (D 1 ) and providing a high temperature heating load to the heated medium, the dilute solution of the new added absorber ( 2 ) flowing through the new added solution heat exchanger ( 5 ) and then entering the absorber (D 1 ) for absorbing the refrigerant vapor came from an evaporator (C 1 ) and releasing heat, the refrigerant vapor, entering the condenser (B
