Résumé

This paper is the part three of the development of a cost-effective adsorption heat pump (AHP) using a natural meso-porous material which is Wakkanai siliceous shale (WSS) impregnated with LiCl. The optimum design of adsorbent bed on the corrugate type heat exchanger and the prediction of the 10 kW scale AHP performances are examined by using a developed three-dimensional numerical simulation program. The actual effective thermal conductivity of the absorbent mixed with aluminum fibers and its overall mass transfer coefficient are measured and their values are used in the calculation. The heat and mass transfer characteristics are analyzed through the calculating results and the optimum size of the corrugate type heat exchanger are discussed. The parametric analyses show that the largest volumetric cooling power (VCP) is 210 W/L and its coefficient of performance is 0.45 under the standard operating conditions when the thickness of is 12 mm.
