I bought a small (5500 BTU) inexpensive portable A/C (not evaporative)
a few years ago and have it in the dining part of my lounge-diner. The
outlet vanes can direct the airflow in various directions and air is
expelled at around 16 deg C when outside temperatures are around 27
like today. It vents into a handy airbrick aperture in my dining room
wall and obviously, I keep all the room windows and doors shut.

It was designed to cool a small room like my dining room alone, and
not the lounge-diner; nevertheless, by running it 24 hours a day, it
keeps the room temperature between 2 and 3 degrees C cooler than the
outside afternoon temperature and relative humidity is always 45% or
less. I have a large fan as well but wouldn't be without the A/C now.
I solve the bedroom problem by having a North facing room , opening
all upstairs windows in mid evening, going to bed late then shutting
all windows until mid-day. The large (quiet) fan is an option if
things are still too hot in the bedroom.

I think you may need a 9000 BTU unit in London, to make what works
here work there.

Just happened on the calculation to work out the size of A/C unit needed.
Size of room in cu metres x 185 = btu / hour (standard room)
Conservatories - x 222
