Abstract
This paper focus on an air-heated humidification dehumidification (HDH) desalination system driven by low grade waste heat. The working processes within the air-heated HDH desalination system are demonstrated, and the performance of the HDH desalination unit is gained and analyzed on the basis of the building mathematical models. In addition of the energy analysis, the entropy generation of the desalination system is also obtained to validate the energy efficiency. The simulation results show that the performance of the HDH desalination system is especially sensitive to the mass flow rate ratio between the working seawater and humid air. It was found that the actual maximum value of gained output ratio (GOR) is GOR=1.80 at the case of msw/mda=0.68. Furthermore, the maximum value of GOR is consistent with the minimum entropy generation within the desalination, which validate the performance analysis in some extent. The obtained results provide some significant references for the design and optimization of the HDH desalination system.
