Rankine cycle integrated with organic rankine cycle and absorption chiller cycle

摘要

A power generation system is provided. The system comprises a first Rankine cycle-first working fluid circulation loop (231) comprising a heater (212), an expander (218), a heat exchanger (222), a recuperator (230), a condenser (234), a pump (242), and a first working fluid; integrated with a) a second Rankine cycle-second working fluid circulation loop (245) comprising a heater (246), an expander (252), a condenser (256), a pump (260), and a second working fluid comprising an organic fluid; and b) an absorption chiller cycle (228) comprising a third working fluid circulation loop comprising an evaporator, an absorber, a pump, a desorber, a condenser, and a third working fluid comprising a refrigerant. In one embodiment, the first working fluid comprises CO2. In one embodiment, the first working fluid comprises helium, air, or nitrogen.
