1. A thermodynamic system comprising:
at least one working fluid collection vessel adapted to contain a liquid phase and a gaseous phase of a working fluid in thermodynamic equilibrium; and
a closed circuit, functionally coupled to the at least one working fluid collection vessel and containing the working fluid;
a chilling arrangement functionally coupled to the at least one working fluid collection vessel and adapted to remove heat from the working fluid collected in the at least one working fluid collection vessel to thereby reduce a settle-out-pressure in the closed circuit, when no working fluid is circulating in the closed circuit.
