| 摘要 |
The present invention relates to a device for controlling a working fluid having a low freezing point and circulating in a closed circuit (10) operating according to the Rankine cycle, wherein said circuit includes a pump (12) for compressing/circulating the fluid in the liquid phase, a heat exchanger (18) heated by a heat source (24) so as to evaporate said fluid, an expansion means (30) for converting the fluid into a vapor, a cooling exchanger (42) cooled by a cold source (F) so as to condense the working fluid, a working-fluid tank (48), and pipes (52, 54, 56,58, 60, 62) for circulating the working fluid. According to the invention, the tank (48) is connected to a negative-pressure generator (50). |
