Influence of the adsorber heat exchanger design on the performance of the heat pump system

Review of Regenerative Adsorption Heat Pumps

“…Cacciola et al 19 examined the effect of metal additives for increasing the effective thermal conductivity of the adsorbent bed. Such additives increase the ratio of dead mass to adsorbent mass and reduce SCP, thereby requiring more massive and expensive adsorbers, unless the ratio of the product of overall heat transfer coefficient and contact area over adsorbent mass, U × A cont /m ads , is sufficiently increased.…”

Modelling and Optimization of an Adsorption Cooling System for Automotive Applications

“…As expected, these models can be used to obtain a theoretical limit regarding performance and capacity of a system, but are not able to identify causes of poor performance when examining experimental data. Several thermodynamic models can be found in the literature [33,34,35,36].…”

“…Cacciola et al [33,34,35] proposed thermodynamic models to predict the performance of an adsorption heat pump machine. However, in their analysis, the performance of the system is limited by the heat transfer inside the sorption bed only, and an equilibrium adsorption state was assumed.…”

“…Cacciola et al [34] The optimization of the design of an adsorption heat pump based on thermodynamic analysis was investigated by Cacciola et al [35] and Benthem et al [36].…”

“…Cacciola et al [35] developed a thermodynamic model to study the effect of the bed design on the performance of a zeolite-water adsorption heat pump. In their model, the cycle time is limited only by the heat transfer inside the bed.…”
