How dry is the air blowing from a dehumidifier?

post #1 of 5
Thread Starter 
Obvious motivation for this question is:

I want to have a dehumidifier blowing on my case to lower the dew point. However, is the air being blow out actually dry, or does it take multiple passes of the air through the evaporator coils to really dry it out?

Well look at it this way. It'll never get more humid than it is at room temp. Whether is takes a while or just one pass through depends on the brand and model.

So it really wouldn't matter if it requires multiple passes. Just let it run on there for 30 minutes and you should be fine.

I thought about doing that but then my question comes from wondering whether there is an advantage to funneling the dehumidifier output into my case instead of the room.

You know a AC unit also works as a dehumidifier, also lets you keep your room cooler.

A dehumidifier is just a AC unit at heart, just uses the cold air to cool the condensing coil

Yes, but I have my house AC set to 74 F already, and any colder feels uncomfortable to me. A dehumidifier supposedly blows slightly warm air.

I suppose I could take a humidity measurement on the outlet of one of my HVAC vents to see what % RH it is. A dehumidifier I imagine would yield a similar result.
