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.
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/
Perhaps it is a Russian conspiracy to keep you all burning that sweet sweet gazprom oil (except the UK, congratulations!). ;- )
Unintended consequences hall of fame. Have they reversed that, or is it just sorta sitting there, like a festering wound?
Edit: about condensate… half of the comfort comes from getting water out of the air so your mammal body works. Some units will require a gravity drain or for you to empty a bucket a couple times a day. Others will have a tricky design to move the water into the hot exhaust duct and evaporate it. I like these.
