Abstract: The development of the traditional dehumidifying technology and its disadvantages are reviewed in this paper. The operational principle，theoretical model and recent advances of the new thermoelectric cooling dehumidifying technology are systemically introduced. Compared with the traditional dehumidifying technology，as a new type of environmentally-friendly and energy-saving dehumidifying technology，the thermoelectric cooling dehumidifying technology is expected to become more and more attractive along with the development of thermoelectric technology，and the improvement of the performance of the thermoelectric cooling dehumidifier coupled with the cost reduction of photo voltaic (PV) solar panel.
