Comment on I've been using this simple trick to keep cool in the heat wave (UK)

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.
