مقارنة أنواع مختلفة من مواد مزيلة للرطوبة في عجلة التجفيف الدوارة في أنظمة التكييف.

Abstract

This study aims to compare different dehumidifying materials used in rotary desiccant wheels used in air conditioning systems. Polymer-based composite materials such as (PVA-silica gel) and (silica gel-AAc) were prepared and their dehumidification performance compared to silica gel (The most widely used material in commercial desiccant wheels worldwide).

The results of this study showed that (Silica gel-AAc) composite material had the highest moisture removal (MR) at different relative humidity levels and regeneration air temperatures. It was followed by (PVA-AAc) composite material and then the pure hydrogel (Silica gel). The results of the study also showed that the rotary desiccant wheel suitable in conditioning system in the temperature range(40-100°C). The moisture removal rate increases at a high rate with the increase of the rotating speed of desiccant wheel within the range(10-40rpm) and then level off at higher rotating speeds.
