How Ductless Split System Dehumidifies a Room?

[jaykchan]

I am wondering how a ductless split system air conditioner dehumidifies a room. I can understand that window air conditioner extracts moisture from air and drip the water outdoor from the back of the air conditioner. I can also understand that a central air conditioner with ductwork can expel water into a drain or something. But I don't understand how the indoor blower of a ductless split system deals with indoor moisture. Does it need a drain hose to drain the water elsewhere?

Thanks for any info in advance.

There is still a drain that either goes outside or into an interior drain somewhere....

Yes, there's typically a drain line in with the refrigerant lines. The installation manuals for many models are available online. Here's one example:

You may have to paste that link back together.

Yes, along with the refrigerant lines going through the wall behind the air handler there is also a drain line. Most units also run the fan a bit slower to allow for more humidity removal.

I've installed a couple of these. Yes, it needs a drain. The drain tube goes out the same direction as the freon tubing, in most cases.

Thanks for everyone who has replied. Now I understand that there is a drain tube going outdoor from the indoor unit of a ductless split system. This makes sense to me now.
