Comment on I've been using this simple trick to keep cool in the heat wave (UK)
tormeh@discuss.tchncs.de 4 days agoThank you. I thought I was insane because surely mobile units would have two tubes if they really needed them. Then I got one with a single tube (the only ones available) and found out that no, I am sane and these units work really badly.
I find mine works fairly well, it’s a 12k BTU unit.
It has one exhaust duct. It pulls in warm air from the room it’s in, cools part of it and pushes it back into the room, the rest is used to cool the condenser and that hot air is sent outside through the duct.
It does have another tube, but it’s a small hose to drain the water from condensed humidity.

Until the room is cooled enough that you are using the air you have paid to cool, to cool the evaporator. Portables are shit.
That’s one of the main reasons their efficiency is lower.
A split unit, especially with an inverter motor, can be 50% more efficient, much less noisy and cool more evenly.
That said, portable units do work. For people who are unable to get a proper split unit, then don’t rule out a portable unit.

That’s why the earlier comment mentioned the portable minisplit, it doesn’t have this weakness
