The possibility of producing cold heat energy by the super active carbon/ethanol-adsorption heat pump (AHP) with the packed bed type adsorber was discussed on the basis of both experimental and calculated results of the transient behavior accompanied by this operation.
The trend of experimental results for heat and mass transfer agrees well with computer simulation under closed-system, one-component, non-isothermal conditions in both adsorption and desorption processes. The super active carbon/ethanol-AHP proposed generates high level cold heat energy by raising the desorption temperature. Therefore, this AHP is applicable to a refrigerator. However, it is suggested that enhancement of heat tranfer in the adsorber is indispensable to obtain high power energy from this type of AHP.
