A direct expansion (DX) air dehumidification system is an efficient way to supply fresh and dry air to a built environment. It plays a key role in preventing the spread of respiratory disease like Swine flu (H1N1). To improve the efficiency of a conventional DX system in hot and humid regions, a...

Membranes were used in combination to liquid desiccant air dehumidification to separate the liquid desiccant from the process air to prevent the problems of liquid droplets crossover. In this review, the developments in this relatively new technology were introduced. The membrane materials used...
