A method of operating an organic rankine cycle system wherein a liquid refrigerant is circulated to an evaporator where heat is introduced to the refrigerant to convert it to vapor. The vapor is then passed through a turbine, with the resulting cooled vapor then passing through a condenser for condensing the vapor to a liquid. The refrigerant is one of CF<SUB>3</SUB>CF<SUB>2</SUB>C(O)CF(CF<SUB>3</SUB>)<SUB>2</SUB>, (CF<SUB>3</SUB>)<SUB>2 </SUB>CFC(O)CF(CF<SUB>3</SUB>)<SUB>2</SUB>, CF<SUB>3</SUB>(CF<SUB>2</SUB>)<SUB>2</SUB>C(O)CF(CF<SUB>3</SUB>)<SUB>2</SUB>, CF<SUB>3</SUB>(CF<SUB>2</SUB>)<SUB>3</SUB>C(O)CF(CG<SUB>3</SUB>)<SUB>2</SUB>, CF<SUB>3</SUB>(CF<SUB>2</SUB>)<SUB>5</SUB>C(O)CF<SUB>3</SUB>, CF<SUB>3</SUB>CF<SUB>2</SUB>C(O)CF<SUB>2</SUB>CF<SUB>2</SUB>CF<SUB>3</SUB>, CF<SUB>3</SUB>C(O)CF(CF<SUB>3</SUB>)<SUB>2</SUB>.
