Portable Air Conditioner - No Vent - No Way
A recent visitor to my website asked if there is such a thing as a portable air conditioning unit without any vent. I wrote back that I'd not heard of one, but would give it a look just in case some new advance in portable air cooling had slipped by me.
What I discovered was the Haier Commercial Cool 14,000 BTU chillwell portable ac best buy (https://easyigbo.com/) Ac. In the merchandise description it says there is no need to use a vent, however shares a "window exhaust kit" is offered with the buying.
I think what they're trying to undertake is persuade you and me that the term "vent" must be applied to permanent installations only like those for clothing dryers, as well as temporary installations, similar to those utilized for portable air conditioners, are not really vents at all - they're "window exhaust kits."
Call it what you will, a proven way or any other the hot air produced by the compressor must be exhausted from the space. So I suppose in case you invest in a Haier you'll be "window kitting" the hot air through the window rather than having to vent it such as everybody else.
The fact of the matter is there is no such thing as a portable air conditioner with no vent.
Therefore if you are searching for a portable cooling unit which does not require venting, (and once again the term "portable" is subject to interpretation) you've 3 choices: A fan, a small window air conditioner, or a portable swamp cooler - also called a portable evaporative cooler.
