Claim 0:
1. A method for controlling a heat carrier in a process for energy storage, wherein
the process comprises carrying out a closed cyclic thermodynamic transformation, first in one direction in a charge configuration/phase and then in an opposite direction in a discharge configuration/phase, between a casing for the storage of a working fluid different from atmospheric air, in a gaseous phase and in pressure equilibrium with the atmosphere, and a tank for the storage of said working fluid in a liquid or supercritical phase;
in the charge phase the process accumulates heat and potential energy in the form of pressure and in the discharge phase generates energy;
in the charge phase, a condensation of the working fluid is executed by means of heat absorption by the heat carrier, executed in a condenser/evaporator which works as a cooler/condenser, in order to store said working fluid in the liquid or supercritical phase;
in the discharge phase, an evaporation of the working fluid, in said condenser/evaporator which works as a heater/evaporator, is performed starting from the liquid or supercritical phase and by transfer of heat from the heat carrier;
the method comprises actively adjusting at least one parameter of the working fluid related to the condensation and/or to the evaporation, in order to control at least one temperature of the heat carrier and to uncouple said at least one temperature of the heat carrier from an ambient temperature; and
said at least one parameter of the working fluid is selected from a group comprising:
a condenser inlet temperature;
a condensation start temperature;
a condensation end temperature;
a condenser outlet temperature;
an evaporator inlet temperature;
an evaporation start temperature;
an evaporation end temperature; and
an evaporator outlet temperature.
