The adsorption heat pumps are a promising technology suitable for the industrial waste heat recovery. In particular, the direct contact configuration can be used to generate high-temperature steam for industrial applications limiting the design complexities. In this paper, a numerical simulation of an original configuration of a direct contact water/zeolite heat pump is presented and discussed. A lumped-parameter model has been developed using the Matlab code. Different sensitivity analyses were carried out with the aim of improving the steam generation.
