Portable home AC units

I have a couple of questions about portable (roll around) AC units.

The specs for the one I bought says under normal use the unit evaporates the condensate and should not require emptying. The 1.5L "emergency" condensate tank on mine requires emptying every 8-10 hours and it is a real PITA. Is it realistic to expect an AC unit to cool the room all the while recycling the humidity that it is removing?

Question #2 Are all portable AC units very noisy? Mine is advertised at
<45 dbA. I don't have a way to measure sound pressure but my ear tells me that the spec is way off base. I suspect it is the way the measurement was made. It seems to make sense that a unhit entirely within a room will be much louder than a unit tha is mostly hanging out the window.

Wayne: I'm no HVAC pro but I agree with your thought process - how can the AC dehumidify the room if it evaporates all of the moisture it removes back in to the room?

The moisture evaporates into the exhaust.

Contact the manufacturer since it's not working as it should.

Is your unit a one or two hose unit?

Tolyn - It WAS a one hose (6") unit. I returned it today. I won't mention the brand but even if it had cooled the room to sub zero I would have returned it. It is advertised as <45dbA yet it sounded like a B-17 and touted as only requiring condensate emptying in "emergency" circumstances which the manual defined as a very cold, damp room. Well, the 1.5L emergency tank filled in just a few hours and it was a serious PITA to empty.

I replaced it with a wndow unit recommended by Consumer reports.
