AI Technical Summary
Technical Problem
Existing energy storage systems require external devices such as heat pumps to regulate temperature during cyclic thermodynamic conversion, which increases system complexity and cost while reducing overall performance.
Method used
By actively adjusting the parameters of the working fluid, such as condensation and evaporation temperatures, independent of the ambient temperature, the heat transfer medium can be separated from the ambient temperature, avoiding the use of external devices.
Benefits of technology
It simplifies the system structure, reduces costs and improves reliability, while maintaining high-efficiency energy storage and conversion performance.

Abstract
A process for energy storage, the process comprising performing a cyclic thermodynamic conversion (CTT), wherein, in a charging phase, condensation of a working fluid (WF) is performed by means of heat absorption by a heat vector (TV) in order to store the working fluid (WF) in a liquid phase or a supercritical phase; wherein, in a discharging phase, evaporation of the working fluid (WF) is performed starting from the liquid phase or the supercritical phase and by transferring heat from the heat vector (TV); wherein it is provided that at least one parameter of the working fluid (WF) related to the condensation and / or the evaporation is actively regulated in order to control at least one temperature of the heat vector (TV) and to separate said at least one temperature from an ambient temperature (T 环境 ) without the aid of systems external to the cyclic thermodynamic conversion (CTT).
