Patent ID: 7225634

Claim:
A triple effect absorption refrigerating machine comprising: a high temperature regenerator; an intermediate temperature regenerator; a low temperature regenerator; a condenser; an absorber; an evaporator; an auxiliary regenerator; an auxiliary absorber; and a path for interconnecting these devices, said triple effect absorption refrigerating machine further comprising: a high concentration circulation path for circulating a solution among said absorber, said auxiliary regenerator, said intermediate temperature regenerator and said high temperature regenerator; and a low concentration circulation path for circulating a solution between said auxiliary absorber and said low temperature regenerator, wherein said triple effect absorption refrigerating machine further comprises: a path for guiding a refrigerant vapor generated in said auxiliary regenerator to said auxiliary absorber; a path for guiding a refrigerant vapor generated in said intermediate temperature regenerator to said low temperature regenerator and said auxiliary regenerator in the heating sections thereof; and a path for guiding a refrigerant vapor generated in said high temperature regenerator to said intermediate temperature regenerator in the heating section thereof.
