Design Proposal

Background

Research Question
Which low-cost, low-tech (Low Fab) desiccant material has the potential to achieve greater levels of thermal comfort? 

Hypothesis
Because of its greater adsorption capacity, silica gel will have the greatest impact in the moisture content inside the environment box.

Construction/Fabrication

Desiccants in either solid or liquid forms have adsorption capacities. As air moves from a fan blower through the dehumidifying system’s zone, comprised of an interchangeable material component, moisture is removed and the processed air is released into the unconditioned chamber. Herein sensors are used to measure the ambient temperature and relative humidity.
