Lower Critical Solution Temperature Air Conditioning

Research Description:
My dissertation research involves a new refrigeration and dehumidification cycle that I invented, which utilizes lower critical solution temperature mixtures that phase separate upon heating. The water-scarce (WS) phase absorbs moisture from air, providing dehumidification, while the water-rich (WR) mixtures evaporates, providing refrigeration. My work involves the theoretical analysis, materials characterization, and experimental demonstration of this new cycle. Moving forward, I aim to find new LCST mixtures that allow for lower indoor temperatures and humidities.
