Abstract

Bu çalışmada, mekanik nem alma sistemlerinin yerine kullanılabilecek, nem alma ve rejenerasyon kolonlarında, daha önce kullanılmamış, polikarbonat dolgu malzemesi kullanılan bir açık sıvı nem alma sisteminin deneysel olarak araştırılmıştır. Sıvı desikant olarak kütlece %45’lik LiBr-su (Lityum bromür-su) çözeltisi kullanılan sistemde dolgu malzemeleri, 6 mm kalınlıklarındaki polikarbonat levhaların 30°, 45° ve 60° kanal açısı oluşturacak şekilde kesilmesiyle oluşturulmuştur. Sözü geçen kanal açılarının, hava hızının ve sıvı desikant debisinin sistemin nem alma verimine, elektriksel ve ısıl performans katsayısına etkisi incelenmiştir.

Experimental Investigation of Thermal Performance Values of Absorption (LiBr-aq) Dehumidification System

Abstract

In this study, an open liquid desiccant dehumidification system, using polycarbonate packing material in dehumidification and regenerator columns, has not been used previously, which can be used instead of mechanical dehumidification systems, was experimentally investigated. The packing material of the system, using 45 mass percent LiBr-aq (Lithium bromide-water) solution as desiccant, was formed by cutting polycarbonate sheets 6 mm thickness to form 30°, 45° and 60° channel angles. The effect of these channel angles, air velocity and liquid desiccant flow rate on dehumidification efficiency, electrical and thermal coefficient of performance were investigated.
