Conventional vapor compression system has high performance of cooling process but has low performance on dehumidifying and mostly is consumed electrical energy that usually get from commercial source. Otherwise liquid desiccant air-conditioning system has low performance on cooling process but has high effectiveness on dehumidifying process. liquid desiccant air-conditioning system also can be powered by cheap energy such as waste heat and solar. In operation of liquid desiccant air-conditioning system dehumidifying and cooling system is not just using cheap energy, the components such as air blower and chiller are usually done by using commercial source. This present study analyses those components operating parameter to save the energy that consumed from commercial source.
Experimental apparatus used in this present study consists of three components those are a chamber, a packed tower and a chiller. Chamber's volume is 40㎥, and packed tower dimension is cubic with side of 0.4m occupied with Norpack type packed column. Air velocities were varying on 2㎧, 3㎧ and 4㎧ and desiccant temperature is 10℃ with other conditions are controlled. Air inlet initial temperature and humidity ratio are set on 14 g/㎏ and 30℃ respectively, desiccant flow rate is 0.63 ㎏/s.
This study shows that higher the temperature and slower the air velocity operation in the packed column liquid desiccant dehumidifier system is more suitable condition for optimization. Hence this condition will give higher electrical energy consumption effectiveness.
