Membranlı boru tipi sıvı desikant nem alma sisteminin tasarımı ve deneysel olarak incelenmesi

Bu çalışmada, membranlı boru tipi sıvı desikant nem alma sisteminin tasarımı yapılmış ve sistemin nem alma performansı incelenmiştir. İmal edilen sistemde suni sosis kılıfı ve Tyvek® Solid olmak üzere iki farklı membran kullanılmış ve bu iki membran ile deneyler yapılmıştır. Yapılan deneylerde havanın Reynolds (Re) sayısı değiştirilerek hava hızının sistemin performansına etkisi araştırılmıştır. Ayrıca deneyler yapılırken ısıl kamera ile membrandan görüntü alınarak membrandaki sıcaklık değişimi gözlenmiştir. Elde edilen deneysel verilere göre sistemin nem alma verimi, suni kılıf için 200 Re sayısında %4.5-6 aralığında, Tyvek® Solid için yine 200 Re sayısında yaklaşık %18.5 olarak hesaplanmıştır.

The design and experimental investigation of membrane-based tubular liquid desiccant dehumidification system

In this paper, membrane-based tubular liquid desiccant dehumidification system was designed, and its dehumidification performance was investigated. In the manufactured system, two different membranes, synthetic sausage casing and Tyvek® Solid were used. The air Reynolds number (Re) was varied during the experiments to investigate effect of air velocity on the system performance. In addition, temperature changes in the membrane were observed by images taken with thermal camera. According to the experimental data obtained, the dehumidification efficiency of the system was calculated in between 4.5-6% at 200 Re number for synthetic sausage casing and approximately 18.5% at the same Re number for Tyvek® Solid.
