Investigation of the Moisture Exchange in a Stationary Adsorbent Layer Through which Air is Passed

Abstract

The nonstationary moisture exchange between a stationary adsorbent layer and the air passed through it has been experimentally investigated. It is shown that the air humidity can be effectively regulated at both the stage of water adsorption (air dehumidification) and the stage of water desorption (air humidification) with the use of commercially produced desiccants. The degree of dehumidification and humidification of the air passed through an adsorbent can be varied from 0 to 1 by varying the nature of the adsorbent, the size of its granules, and the time for which it is in contact with the air flow.

Review of heat/energy recovery exchangers for use in ZEBs in cold climate countries

“…It can be classified as desiccant wheel for their similar principle. Aristov et al [70] investigated how the moisture was exchanged if a stationary adsorbent layer was considered. From their studies, it arises that commercially produced desiccants can be effectively used as a buffer for humidity.…”

On the validity of lumped capacitance approaches for the numerical prediction of heat and mass transfer in desiccant airflow systems

“…The study of the transport phenomena in desiccant airflow systems has been addressed in numerous research works, many of them concerning combined desiccant cooling and dehumidification, air filtering, air dehumidification and energy recovery processes (e.g., [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]). …”
