One question,
How do portable units expel the heat?
Most units I have used in the past either have a heat exchanger (and fan)
mounted outside, or require a vent pipe for warm air to be blown out, so how
does a portable unit which says keep doors and windows closed expel the
heat?

I can't take the heat any more!

Looking at a mobile/cheap air con unit.

B&Q do a couple (although out of stock at the moment) around £180.

Anyone used this before or another similar unit? Any good for cooling
down a 12x12 ft room?

Thanks,
