| Abstract | Air conditioning systems using liquid desiccant have been gaining attention due to their great energy-saving potential, but cooling and heating load for dehumidification and regeneration process remained a vital role in energy consumption. In this research, we proposed a membrane-based liquid desiccant air conditioning system, which is a vapor transportation driven system with gas separation membrane technology, and evaluated its thermodynamic performance by equation-based simulation. The proposed system has five components: an absorber, a regenerator, a membrane for dehydration, a membrane for hydration, and a vacuum compressor. The membranes were used to control solution concertation without heating and cooling; the water vapor separated by the membrane is transported from the dehydration solution to the hydration solution. The vacuum compressor operated to separate the water vapor from the solution and then transport the separated vapor to the membranes. The results showed that the ideal COP (coefficient of performance) of the proposed system in the thermodynamic analysis is 1.55, which is 5.17 higher than that of the conventional liquid desiccant (heat driven dehumidification and regeneration system), which is 0.3 COP at the design air. |
