Novel concept to produce power and cooling with the energy contained in low-temperature (< 200° C), thermal resources is presented in this paper . These resources can be obtained from concentrating solar thermal energy, and from waste heat sources. The concept uses thermal energy in a low-temperature boiler to partially boil an organic type working fluid mixture. This produces rich vapor that drives an expander. The expander’s output is mechanical power; however, under certain operating conditions its exhaust can be cold enough to use for cooling. An analytical study is identified expander efficiency, expander inlet conditions for determining exhaust temperature, consideration of the operating conditions of integrated solar combined power /cooling cycle . The present research provides simulated performance for improving system efficiency.
