Abstract

Solar powered hollow fiber membrane liquid dehumidification system is an efficient, energy-saving, renewable and non-contact dehumidification system, which can effectively solve carry-over problem of traditional liquid dehumidification. In the present work, an exergy analysis model of solar powered hollow fiber membrane liquid dehumidification system is developed. The exergy of the component is analyzed. Effect of inlet paraments of air and cold-water, and solution flow rate on the system performance is investigated. The results show that the major factors affecting exergy efficiency of system are inlet air humidity, flow rate of inlet air, temperature of cold-water, and flow rate of cold-water. In the whole system, the biggest part of exergy destruction happens in solar collector. Improving the solar collector performance is the key way to improve the system exergy efficiency.
