COLD ENERGY GENERATION CHARACTERISTICS OF ADSORPTION HEAT-PUMP USING DIRECT HEAT-EXCHANGE MODULE

Heat and mass transfer characteristics in an adsorption heat pump (AHP ) using a direct heat exchange module (DS-module) of silica gel were e xperimentally studied on the basis of results compared with those for the AHP with a multiple adsorbent-tube (MAT) type adsorber. Ultimate h eat transfer enhancement for an adsorber of the AHP was almost achieve d by using the DS-module and the possibility of its application to a r efrigerator for producing low temperature cold heat energy was suggest ed.
