Just out of curiosity how much more environmentally friendly are proper
air con systems?
It may be better if I move up to one of those

A split portable unit will be about 20% better than one that uses a hose.

A split unit with the compressor outside is about 50% better but I have
never seen a portable one.

They can be seen quite often, slung out the windows of offices. The
outside part is a rectamgular unit with a couple of small fans in, and you
can see a couple of hoses connected to them.

Mine is like that.. but the compressor is inside not outside.
You can tell because the inside unit weighs about 30kg.

This means that the heat produced running the motor has to pass through the
pipes carrying the heat extracted from the room.
This makes it less efficent than having the compressor outside and cooled by
external air.

Like I said I have never seen a portable one with the compressor outside..
they are too heavy for people to hang from windows, etc.
