MMB 10, a portable swamp cooler. Could wheel it inside a room, or could
have it out in your garage to spot cool you.

Look at their data then for air at 80 F and 50% consider that indoor
air ( a 70F supply temp), look at the data for 100F and 10%, consider
that outside air (a 71F supply temp).

You are going to maintain a home then at 80F in a 100 ambient.

If a single MMB 10 could act just on outside air, you would most likely
need 3 indoor units to do what a single outdoor unit could do. You
would be running a significant exhaust on the indoor scheme as well. It
would be approaching mechanically moving 4 times as much air as a
compared to a single outdoor unit.

Where does the 90F in line 120 suddenly come from? All other references
to ambient in your GW jib is for 110F.
