Реферат:
In this communication, we propose a new version of the Large Temperature Jump (LTJ) method for studying the ad/desorption dynamics on representative pieces of heat exchangers (HEx) used in real adsorption chillers. This method is based on direct measurement of the temperature difference ΔT of a heat carrier at the inlet and outlet of the tested HEx fragment after a fast drop/jump of the inlet temperature. This tightly repeats the procedure used in real HExs for transformation and storage of low temperature heat. For the sake of validation, the measurements were carried out with the same adsorbent (AQSOA FAM-Z02) and HEx as well as under the same conditions already comprehensively studied in [1]. It is demonstrated that the measured ΔT-response allows studying ad/desorption dynamics, extracting the characteristic process time and heat with sufficient accuracy. The new Thermal Large Temperature Jump (T-LTJ) method gives similar information as the G-LTJ version being more simple in realization and close to the common procedure for evaluating dynamic performance of real adsorptive chillers. Moreover, the T-LTJ provides valuable information about the heat flux directly transferred to a heat carrier fluid that is not available from other LTJ versions.
