The design and performance improvement of liquid desiccant dehumidification system

Nowadays, energy demand of human being is increasing in parallel to the developing life standarts. 75 percent of the energy is supported from fossil fuel (primary fuel) in our country. According to the data for 2005, 6.1 percent of the energy is consumed for space heating/cooling. The energy used for space heating directed to space cooling in the summertime due to the relatively high number of sunny days in our country. The solar energy potential atlas of Turkey published by the General Directorate of Renewable Energy showed that Mediterranean Region of our country (where the purposed study will be performed) has an annual mean insolation of 1650 kWh per square meters. Moreover, due to the 65 percent annual relative humidity average in this region, both dehumidification and cooling systems are being intensively used especially in summertime. Therefore, most of the consumed energy is utilized for the dehumidification process. Dehumidification process can be done with liquid desiccant dehumidification systems as it can be done with mechanical systems. By using liquid desiccant dehumidification systems in conventional cooling systems, electricity consumption would be reduced 25-35 percent. In this study, experimental setup, carrying out experiments and thermodynamical analysis of a liquid desiccant dehumidification system, which can be used instead of mechanical dehumidification systems and lithium-bromide-water (LiBr-water) is used as desiccant, will be performed.
