> Get a portable, floor standing unit in the 1500 watt range so you plug it in anywhere. It will have a fist sized duct to exhaust hot air, stick that out a window. Now reduce your living space to something it can cool. Try to get the two-duct ones, they are dramatically more efficient. This is reflected in the newer U.S. DoE capacity ratings, which take into account the various ways that single-duct portable air conditioners are not so great. > Others will have a tricky design to move the water into the hot exhaust duct and evaporate it. I like these. That seems really convenient, can anyone comment on the effect that has on efficiency? It seems like if the hot side is hot enough, re-evaporating the condensate on the hot side should improve efficiency.

Are the two-duct portable air conditioners even available on the European market? They certainly don't appear to be a thing here in the UK as far as I can tell.

  The omission is shocking, I can't seem to find any on UK or German Amazon. Though on amazon.de I see at least one alternative to the Zweikanal-Klimaanlage or whatever you'd call it; a small split system with two condensers for just four-hundred euro. Though it seems like it'd likely warrant professional installation, and therefore €€€. https://amazon.de/dp/B06XTQKLXM/ https://amazon.de/dp/B06XTQKLXM/ Perhaps it is a Russian conspiracy to keep you all burning that sweet sweet gazprom oil (except the UK, congratulations!). ;- )

    There's plenty of split units in the UK too, but those require professional installation and quite possibly also planning permission with a full professional noise assessment. No dual-hose portables though. I'm not sure why; we don't seem to have banned them like Australia accidentally managed to do (they imposed efficiency requirements on dual-hose units that portable aircon couldn't meet whilst exempting the single-hose variety).
