[Greenbuilding] Central vs window AC

[John Straube]

That is very cool Robert!
We have looked at solar recharged dessicants before but these systems are not "off the shelf" or small enough for single family residences. 
That said I think this a great technology that can be developed to be the winner. 
Another approach, not as efficient, is dry dessicants on wheels with solar regeneration. There are some smaller units suitable for residences but they are not yet worked out. 
Building a custom system makes a bunch of sense for multifamily and light commercial. 
Hope you write up what you learn on this project when it gets through the first summer. Lots could benefit from that experience. Like me!

We are currently building a residential multifamily building that is using a Liquid Desicant unit from Advantix to pretreat and Dehumidify the outdoor air we send to the apartments. 

All return air is then sent back to the unit through a separate HRV that will pull any remaining energy from it to assist the operation of the unit which by the way can be a bit of an energy hog. 

This technology allows us to use a small 5tn GR source heat pump to run small fan coils for each unit.
