If humidity levels are high, the units may not condense all the water/humidity in interior air which can make them less effective than a traditional wall or window unit or whole house ac unit and results in more humid interior air than what is achieved with other ac units. Some have water collection tanks which still need to be emptied. It appears from comments on websites that your model has a tank which needs to be emptied if used in Dehumidify/AC mode. Check the owners manual for proper procedures.

"Does this unit have self-evaporating capability? If not, how often do I need to empty it? Thanks!

It is self evaporating but there is a spot on the bottom to empty it. So although it says self evaporating I guess it needs to be emptied. Mines run 3 days straight and hasnt filled up yet.

The unit does have self-evaporating capability in the "Cool", or A/C, Mode. For the "Dry", or Dehumidifier, Mode, the water collection tank needs to be emptied about every 2 hours or so.

No it does not have an evaporating fan. The relative humidity and size of the catch basin will determine how often you need to empty it.

No, it does not have self evaporating capability.
It has a plug in the back of the unit that you can drain to a container or outside your house using a hose.
The tank can fill on 2 days or sooner if humidity is high. The unit has a light indicator that turns on when the tank is full to let you know that is time to drain.

Water tank draining procedure...or attach a hose to the unit to drain condensed water out a wall opening with a short hose...you'd would have to drill a hole through an exterior wall that sits lower than the drain port so that any excess water would drain out of the unit rather than emptying the tank periodically...or run a hose from the unit to a floor drain if available.
"EMPTYING THE WATER COLLECTION TANK
When the internal water collection tank is full, FL
will appear in the display and the air conditioner
will turn off until the tank is emptied.
Unplug the air conditioner, disconnect
the exhaust hose from the back, and move
the air conditioner to a suitable drain
location or outdoors. You may also place
a pan under the drain that will hold up
to 3 pints of water.
Remove the drain cap and the rubber plug
from the drain outlet.
Once the water collection tank is drained,
reinstall the rubber plug and the drain cap,
making sure it is on securely.
Place the air conditioner in the desired
location, reconnect the exhaust hose, and
plug in the air conditioner.
During the dehumidifiying mode remove the drain plug and the exhaust from the back of the unit.
NOTES: When turned on after being unplugged, the air conditioner will automatically reset to
COOL mode, with a temperature setting of 72°F.
Using the bottom drain port
Install a drain hose (18mm [11/16"] inside diameter) and place the open end of the hose a suitable
drain location or outdoors."

I recently bought a portable air conditioner which is supposed to "evaporate" the condensed water rather than accumulate it in a tank (to decrease frequency of emptying). It is an LG "12,000 BTU Portable Air Conditioner and Dehumidifier Function" Model # LP1213GXR. The question I am having about it is: where exactly does an air conditioner like this evaporate the water to? To outside or back into the house? For some reason the humidity in my house is much greater than it was with a window unit and, secondly, when I use the unit in a closed off room (such as in my bedroom at night) things occasionally feel a kind of "cool damp" - like my comforter, for instance (which the unit points towards). This is what is making me question where it evaporates to... I assumed it had meant outside, but maybe I was wrong? Anyhow, any knowledgeable answer would be greatly appreciated... and any advice as well. Thank you in advance :)
PS the reason why I got rid of the window unit is because no matter what angle I put it at, water kept running into my wall and creating damage... so switching back to a window unit really wont help.
