PURPOSE:To make up working fluid by mixing water and 2, 2, 3, 3-tetrafluoropropanol, which is especially used in Rankine cycle and has those efficiencies of low corrosion, harmlessness, and applying not so hot heat source. CONSTITUTION:Rankine cycle consists of heat addition to working fluid to evaporate, expansion of it in an expansion equipment to create mechanical energy, and compression. The working fluid used in the cycle is the mixture of water and 2, 2, 3, 3-tetrafluoropropanol. The ideal mixture is azeotropic one which consists of 27.5% in weight of the former and 72.5% of the latter or may consist of 7 to 47% of the former and 93 to 53% of the latter. |
