Portable AC - what is the difference?

I am looking for a way to cool my computer room this summer (one with hose out the window) but I am confused by the difference between a straight portable ac and one features a fan, dehumidifier and air conditioner all in one portable unit - does this make a difference for cooling a small room? Canadian Tire has them on sale right now.

My question was about portable air conditioners, not traditional window air conditioners.

Most units have all 3 functions: fan, AC and dehumidifier.
Just ignore that and go by the BTU you need and by the price.
"Fan" is pretty obvious as it's just the fan on with the compressor (cooling) off.
Very few people use the dehumidifier function. I never did.
Maybe if you have a humid basement in the Spring...

The units can be heat pumps (A/C with a reversing valve) and heat as well.

One with dual hose (one for cool air to come in and one for hot air to go out (or v-v depending on what you are doing) is said to be much more efficient than a single-hose unit.

Dual-hose are getting very difficult to find.
I'm actually looking for one at the moment if somebody can post...

SACC= effective cooling after inefficiencies accounted for. A single hose is less efficient than a two hose unit cause you have to cool the replacement air. You might have to dig into the spec to find SACC

draws as much electricity as a 14,000 btu AC but only produces 12,000 btu unit cooling (more efficient)

draws as much electricity as a 7,500 BTU AC but only produces 5,000 BTU cooling (less efficient)

Be aware that it's a 'pseudo' dual hose design, not a true dual hose portable.

Look into Whynter A/C units. I know they still make true dual hose portables.

Oh! Thanks! That's probably why Whynter are so expensive...

$1,117 on amazon.ca

$1,262 on amazon.ca

$1,285 on amazon.ca

Would you happen to know what the difference is between the last 2 models?

Also, in a few words, what's "pseudo" dual hose?

By "pseudo" dual hose I mean that it's one hose, with a smaller hose within the larger hose. It's not 2 separate and distinct hoses like most dual units.

As for the units mentioned above, it looks like the second one has a heater function.

Thanks, I didn't know such a thing existed.

You always have to be on your gards... sigh!
That unit doesn't even seem to have auto-evaporation.
No emptying buckets for me!

Do you have any link about that pseudo dual hose thing?
What's the difference?
Why would they do that?

It seems the heat exaust is inside the air intake.
Maybe that diminishes heating the room with the hot air hose of a traditional dual hose system.
But I already insulate that hose with a blanket...
