After the many discussions we had over the summer about aircon,
I decided to go ahead and install one, in readiness for next summer.

The room is a very modest home office, 3.5x4.5m, with lots of
PCs and two people in it most of the time.

I went for a split unit for obvious reasons and I wanted about
2.5-3kW. After talking to a supplier, they managed to convince
me that I ought to go for a cheaper generic Chinese unit rather
than the Fujitsu which I initially wanted.

Given that the Fujitsu was about £950, and the unit they
recommended was only £550 all in, and that it would only be used
for say 2 months of the year, I decided to go for the cheaper
one. I may end up regretting that, I may not - I don't know.

The unit included all the hoses, multicore cable and brackets
for a complete self install. The install was a piece of cake -
the hardest part was the 3" hole through the 2' wall.

Once you've installed it, you bleed off a small amount of
refrigerant through the system, which flushes out the air.
That's it - no vac pump needed.

It's now running fine (there was a minor problem with the main
indoor unit fan rubbing on the case, but a small modification
fixed that).

I will post if it breaks or anything bad happens.

How noisy is the unit? Would you be able to sleep with it on? I'm
looking at a similar project for a loft conversion, so the noise factor
is important, as the room will be a bedroom.

Also, what are the power requirements? Did you need a seperate feed
from your consumer unit, or is it a relatively low consumption?

Finally, the outside unit: I'd be looking to place this reasonably high
up on the wall, out of the way: how big and how heavy (ie: easy for one
man on a ladder, or bloomin' difficult will do!) is that part?

So many questions - sorry!

We sleep with a fan on in the summer anyway - so that may
prejudice my feelings.

The fan has different speed settings. On medium, it's about the
same noise level as our old 3 speed fan on full. So yes,
sleeping with it on would be fine.

It's 3kW, so just plugs into the mains.

It's large (~3'x2'x1'), and weighs about 30kg (~60lb). I
wouldn't want to carry it up a ladder on my own.

I mounted it at head height on the outside of the house. That
was easy.

So many questions - sorry!

No problem, that's why I posted.

Ceiling fans on slow speed are near enough totaly silent and make
rooms very comfortable it doesn't take much air movement for this.
Though I appreciate that getting a 4' dia ceiling fan into a loft
conversion might be a bit problematical...

Simple, heavy insulation and a fan ventilating the place (over the computer
equipment is probably best) is what you need. While converting the loft
install the extra insulation and ventilation which will be probably a lot
less than £550.

You're missing the point - when it's hot, moving air is all well
and good, but high humidity means your sweat doesn't evaporate
very easily. Aircon will bring the humidity in the room down to
a nice low level, making it much more comfortable.

I've worked in both air conditioned and fan cooled environments,
and aircon wins hands down.

No they don't. They don't cool and are totally inadequate for most of the
summer. Have you considered planting geraniums outside? These will produce
a 15 degree drop in inside temperature - or so it is claimed. Apparently
theu also drop humidity by 40 per cent.

Yes, but the number of geraniums required would probably cost more than

Not by the village idiot though...

I installed a DeLongi system in my home office a couple of years ago. Nice
remote controlled indoor unit with all the moving bits, flashing lights,
etc. Not too big. approx 1m wide, 400mm high.

Outdoor unit not bad looking.

Indoor unit came with umbilical containing hoses and supply cable for
connection to outdoor unit. Simple installation. 13A plug on the indoor unit
(I plugged mine into socket in loft space) and the three connections of the
umbilical.

Works a treat.

My only crib is that the umbilical is not long enough but then if it was
twice as long it still wouldn't be long enough!

I hired in a hydraulic boom an operator for an hour to lift the outdoor unit
up onto it's brackets (pre-fitted to wall) as it's at loft height and is
bloody heavy. Ladders not a sensible option.

Total cost... £400 for the aircon (ex demo - usually 900) plus £80 for the
boom.

Opinion: Brilliant.

Well they do in Thailand and Malaysia, BTDTGTTS... Cheap accomodation

Whilst they don't cool the air they make it move, this movement keeps
you cool naturally. There is a big difference between a slow 4'
ceiling fan and an ordinary stand or table fan. The ceiling fan sets
up a gentle (or not so gentle on high...) whole room circulation, the
table fan just blows a little bit of air about.

Even this years summer was not as hot as the above places and the
humidity was nothing like it either.

Good question. I specified a non-heat pump model when I ordered
it, but the remote control has several heat functions. But I
haven't tried it.

But given that we have CH, I don't think I'll be using it to heat.

No problem - just tried it.

Took a long time for the outside unit to reach temperature, but
once that happened the fan kicked in and it started blowing hot
