Those things are not good. They are basically advanced fans. The entire “hot side” is still 8naode your house, and whole it has the hose to pump hot air out, essentially more air (normally from outside, which will be hot) has to come in to replace it. Ultimately thosw machines will make your house hotter, even if they are able to blow cold air on a specific area.
Strangely the old American style ones they hang out of a window are some.of the most effective, though we don’t really have any windows like that in Europe anymore to hang those AC units out.

There are dual hose variations. I think Hisense and Whynter sells them here in the US. If you can find them you should always go for those.
