Humidifer in lieu of sprayer?


Has the prospect of a residential/commerical humidifer been considered as the means of desorbing the resin? High humidity is cited by Wang et al. as being sufficient for the evolution of CO2 from the material. The homogeneity of water vapor in atmospheric humidity may further be more fine relative to spray and may therefore provide a more complete and uniform desorption of the membrane. The humidifier could conceivably be an equivalent source of on-demand water.

Thank you for inclusion in the DACC development!

Take care :slight_smile:

@freiburgermsu This is a very challenge to be addressed with moisture swing DACC - figuring out a way to make it more environmentally tolerant, specifically better operation in high humidity areas. One interesting area of research that we discussed early on involves the potential use of metal organic frameworks (MOFs) to absorb H2O on the intake, and then recycling it for sorbent saturation. There is a startup based out of MIT called Transaera that is looking into the for residential air conditioning in high demand emerging markets like India. They say that dehumidification using MOFs could make ACs 5x more efficient. And in designing for this market they need to make their tech small, cheap and super low energy in order for it to meet the need. Exactly what we would require for VIOLET. Here is a paper that one of the Transaera principals wrote on MOFs for this AC application.

Would be very cool to explore this further and see if it could inspire any directions for VIOLET. Definitely something we need to focus on at some point. Would really welcome your thinking and contributions! I know @kristin was giving this some thought at one point…
