Device and method for the continuous thermochemical production of cold

A thermochemical method for the production using a system comprising a first reactive device and a second reactive device, the first reactive device comprising a first reactor and the second reactive device comprising a second reactor, each of the first reactor and the second reactor containing a reactive product;

• and a first reservoir and a second reservoir, each of the first reservoir and the second reservoir containing a gas, the reactive product capable of absorbing the gas, the system further comprising a condenser and an evaporator, the reservoir being able to communicate with the condenser and the evaporator, said reactive product and the gas being such that, when placed together a thermochemical gas absorption reaction occurs resulting in the absorption of the gas by the reactive product, and gas desorption reaction occurs when heat is applied to said reactive product when said reactive product has absorbed the gas, the thermochemical gas absorption reaction having a rate of progress, the rate of progress having a maximum value corresponding to a desired maximum rate of progress and a minimum value corresponding to a minimum desired rate of progress;
• operating the first and second reactive devices in opposite phase so that, when the thermochemical gas absorption reaction occurs in the first reactor, the gas desorption reaction occurs in the second reactor, wherein the rate of progress of said thermochemical gas absorption reaction is determined during the production of cold.
