Box with proposed HP-AWH prototype The performance of our proposed HP-AWH is investigated by installing the prototype using a PS-20% sample (approximately 12.89 g) in the box containing a filled water beaker (containing 73 g water and an internal dimeter of 4.8 cm). The PS-20% sample was chosen because of its excellent sorption, desorption, and wicking properties, as well as the fact that it was less brittle than PS-30%, and it did not leak during the experiments at high RH.
