...Ali Al-Alili; Yunho Hwang; Reinhard Radermacher Solar air conditioners (A/Cs) have attracted much attention in research, but their performance and cost have to be optimized in order to become a real alternative to conventional A/C systems. In this study, a hybrid solar A/C is simulated using...

... of the cycle, i.e., turbine inlet condition, are set at 700 °C and 20 MPa, respectively. Running the cycle under an optimized pressure ratio when the cooler exit temperature is 35 °C, the temperature entering the solar receiver is obtained as 530 °C. The flow needs to be heated from 530 °C to 700 °C inside...
