US 2021/0063082 A1 · A THERMODYNAMIC SYSTEM CONTAINING A FLUID, AND METHOD FOR REDUCING PRESSURE THEREIN

Abstract

A thermodynamic system containing a working fluid is disclosed. The thermodynamic system comprises at least a working fluid collection vessel (11) adapted to contain a liquid phase and a gaseous phase of the working fluid in thermodynamic equilibrium. A chilling arrangement (51) is functionally coupled to the fluid collection vessel (11) and adapted to remove heat from the working fluid collected in the working fluid collection vessel (11) and thereby reduce pressure in said thermodynamic system. Also disclosed are methods for depressurizing a thermodynamic system containing a working fluid in liquid/gas equilibrium.

A thermodynamic system containing a working fluid and comprising at least a working fluid collection vessel (11;

23;
355) adapted to contain a liquid phase and a gaseous phase of the working fluid in thermodynamic equilibrium;
wherein a chilling arrangement (51;
251) is functionally coupled to said working fluid collection vessel and adapted to remove heat from the working fluid collected in the working fluid collection vessel and thereby reduce a settle-out-pressure in said thermodynamic system, when no fluid is circulating in the thermodynamic system.

A method for reducing a fluid settle-out pressure in a thermodynamic system containing a working fluid and comprising at least a working fluid collection vessel, adapted to contain liquefied working fluid and gaseous working fluid in thermodynamic equilibrium;

the method comprising the steps of:
removing heat from the working fluid;
and
condensing gaseous working fluid into liquefied working fluid thus reducing said fluid settle-out pressure in the thermodynamic system.
