dehumidifiers

I tried the A/C during a tropical storm in TN, got very cold but it was still very damp. Might have waited too long before kicking it on. I've heard you can turn on both the A/C and the heat at the same time, if you have the option. You'd need separate controls.

As flguppie and Chris have done it, and they live in FL, give it a try.

In my humid climate, I run a dehumidifier most of the time. It sits in the kitchen sink, drains into the gray tank. Since I park on gravel, I leave the valve open so it can drip on the ground.

One thing to be aware of when selecting a dehumidifier. The old mechanical control types would restart after a power failure. Some of the electronic models will not restart automatically after a power failure, requiring you to restart the unit. There are electronic control models that store the settings and restart automatically when the power is restored.

Without the automatic restart feature, you could leave your rv and have the dehumidifier fail due to a power failure.

I've had one running almost nonstop the past seven years. 70-pint. When TT is in storage a low setting takes care of things. When I'm away a few days I run the DH as it is less of a strain on things. Running an A/C on low fan is a problem I'd avoid. A camper burned up here when a neighbor did that. Bad park electric voltage and all. The DH leaves the interior hot, but dry. It's easy for the A/C unit to cool it off from the 90's. And much more comfortable than the clammy air the A/c would struggle to dry.

Why not just leave the air conditioner on. Shades closed, with the thermostat set around 85, it will keep it dry.

This is what we do...S FL heat + humidity. We set the AC. The dehumidifiers exhaust heat into the room, making a TT even hotter.

Ummmm,,,, Noooo,,, They are not going to make it any hotter. But, they are definitely not going to make it any cooler.

It's kinda hard to explain.

They will make it warmer because the heat pump system is not 100% efficient. The excess power is converted to heat (and a vanishingly small amount of acoustic and electromagnetic energy).

It's identical in concept to why the converter also warms up the interior of the RV somewhat; it's not 100% efficient either, and the excess energy nearly all becomes heat which has to go somewhere.

Ya, OK, I understand that. But, if it's 95 degrees in the RV to begin with is the little extra heat being made by the dehumidifier compressor going to be enough that you will notice the difference???
