The adsorbent material has an important role in the improvement of desiccant cooling system performance. Super Desiccant Polymer (SDP) is chosen in this work as a sophisticated desiccant material characterized by excellent adsorption capacity and durability. The mathematical correlations of adsorption isotherm on SDP surface, adsorption heat and water diffusivity coefficient are used to model the SDP desiccant wheel by means of Comsol software. Modeling results are validated by an experimental data base. They serve as a base for the determination of the SDP wheel effectivenesses ԑ1 and ԑ1 which are equal to 0.02 and 0.83, respectively. The application of desiccant cooling system performance with SDP desiccant wheel in a hot and dry weather of the region of Gabes (south-eastern Tunisia) leads to a coefficient performance (COP) value equal to 1.1. This result is better than the COPs of other air conditioning desiccant systems which use zeolites and silica gel wheels. Moreover, the COP of desiccant cooling system with SDP desiccant wheel is the best for a wide range of operating conditions.

聚丙烯酸钠盐除湿轮除湿冷却系统性能分析

吸附材料在提高干燥剂冷却系统性能方面具有重要作用。超级干燥剂聚合物 (SDP) 在这项工作中被选为一种复杂的干燥剂材料,其特点是具有出色的吸附能力和耐用性。通过Comsol软件,利用SDP表面吸附等温线、吸附热和水扩散系数的数学相关性对SDP干燥剂轮进行建模。建模结果由实验数据库验证。它们作为确定 SDP 车轮有效性 ԑ 1和 ԑ 1 的基础分别等于 0.02 和 0.83。在加贝斯地区(突尼斯东南部)炎热干燥的天气中,使用 SDP 干燥剂轮的干燥剂冷却系统性能的应用导致系数性能 (COP) 值等于 1.1。该结果优于其他使用沸石和硅胶轮的空调干燥剂系统的 COP。此外,带有 SDP 干燥剂轮的干燥剂冷却系统的 COP 是最适合各种操作条件的。
