In adsorption heat pumps, the properties of the porous adsorbent and the refrigerant determine the performance. Major parameters for this working pair are the total uptake of the adsorptive, its kinetics, and the heat transfer characteristics. In the technical application despite powdered adsorbents, thin consolidated layers of the adsorbent can be attractive and obtained by a binder‐based approach but likely result in competing material properties. Thus, for a process optimization, the accessible parameter space and interdependencies have to be known and were deduced in this work for model porous carbons (carbide‐derived carbons derived from TiC and ZrC) and methanol as well as the addition of different amounts of boron nitride, silver, and graphite as heat‐conductive agents and the use of two binders.

基于碳-甲醇的吸附式热泵:使用碳化物衍生的碳模型材料识别可访问的参数空间

在吸附式热泵中,多孔吸附剂和制冷剂的性能决定了性能。该工作对的主要参数是吸附剂的总吸收,其动力学和传热特性。在技​​术应用中,尽管吸附剂是粉末状,吸附剂的薄固结层仍然很有吸引力,并且可以通过基于粘合剂的方法获得,但可能会导致竞争的材料性能。因此,为了进行工艺优化,必须知道可访问的参数空间和相互依赖性,并在此工作中推导了模型多孔碳(衍生自TiC和ZrC的碳化物衍生的碳)和甲醇以及添加不同量的硼的方法。氮化物,银和石墨作为导热剂,并使用两种粘合剂。
