The liquid desiccant air-conditioning system has been proposed as an alternative to the conventional vapor compression cooling systems to control air humidity. The complete system of liquid desiccant air conditioning system is consisted two main components those are humidifier (regeneration) and dehumidifier. Humidifier part is connected to the load when summer season which is the air condition is hot and humid have to be turned into comfort condition on human. This paper purpose is performances study of air flow rate effect on a structured packed tower on cooling and dehumidifier system using liquid lithium chloride as the desiccant.
Experimental apparatus used in this present study is consisted of three components those are load chamber, packed tower and chiller. Load chamber's volume is 40㎥, and packed tower dimension is cubic with length 0.4m occupied with packed column. Totally, 15 experimental has done using 5 times repeat on each variable of air velocity that varying on 2㎧, 3㎧ and 4㎧ with other conditions are controlled. Air inlet initial temperature and relative humidity are set respectively on 30℃ and 52%, desiccant flow rate is 0.63 ㎏/s, desiccant temperature is 10℃ and desiccant concentration is 0.4.
The result of this study shows that averagely, the moisture removal rate and the heat transfer rate are influenced by the air velocity. Higher air velocity will increase the heat transfer and decreasing the moisture removal rate. At adiabatic condition the air velocity of 2 ㎧ respectively is having the higher moisture removal rate acceleration then the air velocity of 3㎧ and 4 ㎧ until the steady state condition
