This book investigates the adsorption dynamics of water methanol ethanol and ammonia vapor
on loose and consolidated adsorbent beds as well as the impact of this aspect on the overall
performance of adsorption systems for heat transformation. In particular it presents the
results of kinetic measurements made using the large temperature jump (LTJ) method the most
efficient way to study adsorption dynamics under realistic operating conditions for adsorptive
heat transformers. The information provided is especially beneficial for all those working on
the development of novel adsorbent materials and advanced adsorbers for heating and cooling
applications. Today technologies and systems based on adsorption heat transformation (AHT)
processes offer a fascinating option for meeting the growing worldwide demand for air
conditioning and space heating. Nevertheless considerable efforts must still be made in order
to enhance performance so as to effectively compete with commonly used electrical compression
and absorption machines. For this purpose intelligent design for adsorption units should above
all focus on finding a convenient choice of adsorbent material by means of a comprehensive
analysis that takes into account both thermodynamic and dynamic aspects. While the
thermodynamic properties of the AHT cycle have been studied extensively the dynamic
optimization of AHT adsorbers is still an open issue. Several efforts have recently been made
in order to analyze AHT dynamics which greatly influence overall AHT performance.
