Abstract: The adsorption heat pump system is considered to be one of the leading technologies for utilizing low temperature thermal energy, because it can generate cold heat energy at around 283 K for air conditioning without any mechanical power by utilizing low temperature heat as the regeneration heat source of an adsorbent. Many theoretical and experimental studies have already been conducted with the objective of enhancing the cold-heat output of the adsorption heat pump system. However, there are still some problems in the practical use of the adsorption heat pump system. The most serious problem is that the small cold heat output per unit volume of the adsorption heat pump,and its reasons were the bad vapor diffusion and heat transfer in the adsorption layer. For increasing the cold heat output, we have considered ammonia/SAC combination adsorption heat pump from the viewpoint of the promoting the vapor diffusion. We modeled in the heat transmission and the vapor diffusion of the adsorption layer, and estimated them. The result indicated that ammonia heat pump has the very good vapor diffusion,and the only heat transmission is rate-controlling step in the ammonia adsorption heat pump.
