SIVI DESİKANT NEM ALMA SİSTEMİNİN TASARIMI VE PERFORMANSININ GELİŞTİRİLMESİ

Bu çalışmada, mekanik nem alma sistemlerinin yerine kullanılabilecek bir sıvı desikant nem alma sisteminin tasarımı yapılarak termodinamik analizi yapılmıştır. Tasarlanan ve imalatı yapılan açık sıvı nem alma sisteminin ana parçaları absorber, rejeneratör ve ısı değiştiricileridir. Çalışması yapılan açık sıvı nem alma sisteminde dolgu malzemesi daha önce kullanılmamış polikarbon levhalardan hazırlanmıştır. Polikarbon dolgu malzemeleri kanal açıları 30o olacak şekilde hazırlanmıştır. Sistemde sıvı desikant olarak LiBr-Su (Lityum bromür-su) çözeltisi kullanılarak sistemin nem alma verimi, entalpi verimi ve duyulur ısı oranı parametreleri açısından performans incelemesi yapılmıştır. Analiz sonucunda sıvı desikant nem alma sisteminin nem alma verimi yaklaşık %15 olarak bulunmuştur.

Anahtar Kelimeler:

Nem alma sistemi, polikarbon dolgu malzemesi; sıvı desikant
