This study is experimentally performed for using the oyster shell as a desiccant in the batch type system. The peltier element(thermoelectric device) is used for absorbing and releasing the adsorption and desorption heat generation. The cooling and heating effects of peltier element exist in this experiment and these effects are generally known phenomena among some references. The increase in electric current induced into peltier element is effectively release the heat generation of adsorption and desorption. Consequently, the non-dimensional adsorption and desorption amount would increase with increase in electric current. However, in the case of adsorption, the increase of induced current into peltier element, the heat of cold side can not release sufficiently. So the heat of hot side of peltier is transferred into the cold side.
