Working fluids for solar,rankine-cycle cooling systems

Data are presented on the selection of appropiate working fluids suitable for solar cooling of buildings. Safety operation, system reliability, fluid thermal stability, pressure drop, heat transfer rates, and maximum allowable heat flux have been investigated for halogenated and fluorinated compounds in several prototype developments that are presently under construction. The results indicate that refrigerant R-113, followed by fluorinert fluid FC-88, are potential candidate working fluids for this type of application.
