Paper presented to the 3rd Southern African Solar Energy Conference, South Africa, 11-13 May, 2015.
A mathematical model is proposed to study the heat and mass transfer performance of a hot water driven hollow fiber membrane-based liquid desiccant air dehumidification system. The system can be extended to solar energy cooling in summer, especially in hot and humid regions. The benefit with this technology is that the liquid desiccant is not in direct contact with the process air, therefore the problem of liquid droplets cross over is prevented. With the model, the effects of various operating parameters like fresh air temperature and humidity on system performance, in terms of SDP (specific dehumidification power) and COP (coefficient of performance), are discussed.
