Abstract: In this work, a new version of the Large Pressure Jump (LPJ) method was proposed for studying the ad/desorption dynamics on representative pieces of a real “adsorber - heat exchanger” (AdHEx) for adsorptive heat storage and transformation (AHST). The core of the new approach is a direct measurement of the temperature difference ΔT of a heat carrier at the inlet and outlet of the tested AdHEx fragment. This difference is caused by a jump/drop of the adsorptive pressure which has initiated adsorption/desorption process. The measurements are carried out for the working pair “methanol - composite LiCl/silica” under typical conditions of a new cycle “Heat from Cold” (HeCol).
