Process of management of a thermochemical reaction or of a solid-gas adsorption

Process of management of a thermochemical reaction or of a solid-gas adsorption located in a reactor containing a reactive agent able to react in a reversible manner with a gas, the reactor being connected, by a connection devoid of a control valve, to an evaporator/condenser assembly for the gas, the reactor and the evaporator/condenser each being provided with means permitting selective exchange of calories with the environment, characterized in that the process of management comprises the steps consisting of:

• thermally isolating the reactor and the evaporator/condenser assembly from their environment;
• placing the reactor in thermal communication with its environment in order for the active agent to react with the gas, with the production of cold at the evaporator;
• placing the evaporator in thermal communication with its environment in order to selectively cool the latter;
• the process being characterized in that it comprises the step of isolating, selectively, solely the evaporator/condenser assembly from its environment in order to stop the reaction at a point of the reversible cycle.
