Simulasi Pengaruh Variabel (T dan v) Masuk Udara Dan Desiccant Terhadap Laju Dehumidifikasi Dengan Menggunakan CFD

Abstract

Dehumidification is processing derivation of humidity of atmosphere. System dehumidifier process where atmosphere humidity ( vapor) is decreased permeated by absorbent media (sorbent) using concentration of solubility lithium chloride ( LiCl) - water ( H2O) with concentration of between 28 - 40% Mass transfer between air process and LiCl because of partial pressure difference made concentration of sorbent is decrease. Regenerator is used to reconcentred sorbent, so it can be used again in dehumidifying process. Research with simulation software computational fluid dynamic ( CFD), aim to know parameter influence like velocity and temperature from the air and also desiccant with various concentrations, to dehumidification speed and the air exit temperature. From simulation process, dehumidification speed experiences improvement along with increase of speed desiccant and its concentration. While temperature experiences improvement increasinglyly height of speed of atmosphere and speed desiccant.
