METHOD FOR OPERATING A THERMODYNAMIC CIRCUIT, AS WELL AS A THERMODYNAMIC CIRCUIT

摘要

The invention relates to a thermodynamic cycle (1) with at least: -one first heat exchanger (W1) for creating a first heated or partially evaporated working medium flow (15) by heating or partially evaporating a liquid working medium flow (14) by heat transmission from an expanded working medium flow (12); - a second heat exchanger (W2) for creating a second at least partially evaporated working medium flow (18); - a separator (4) for separating a liquid phase (19) from a vaporous phase (10) of the second working medium flow (18); -an expansion device (2) for creating an expanded vaporous phase (10). According to the invention, pressure pulsations are prevented during the start-up of the cycle in that the vaporous phase (10) separated by the separator (4) is conducted past the expansion device (2) and the first heat exchanger (W1). The liquid phase (19) separated by the separator (4) is cooled in the first heat exchanger (W1) by heat transfer to the liquid working medium flow (14). After the first heat exchanger (W1), the cooled, separated, liquid phase and the separated vaporous phase (10) are brought together.
