Air conditioning advice needed

Nick1881 · 4 Jul 2013 at 23:51

I'm looking at getting air conditioning for my room. Now before people shout that it's pointless in the UK please read.

I have a small room (3.6 x 2.8 m) the windows are very small opening, I keep the door shut, I'd rather have the windows closed to reduce noise from outside and my music/movies being heard outside.

My room gets very hot with everything running, here is what's in my room.

60" plasma - gives off a lot of heat.
2 x amplifiers (Stereo and AV)
High end computer overclocked of course
HP Microserver
Subwoofer with amp
Modem and router and other things.

It doesn't need to be warm outside for it to get too hot in this room. Also I only have storage heaters which suck, I'm told these air con units cool very efficiently.

I'm looking at Mitsubishi SRK HG units.

2.6 Kw 9,000 BTU unit or
3.6 Kw 12,000 BTU unit

The seller suggests the 12,000 unit and it's only £50 more, should I go with his advice?

I tried some calculators and they say 9,000 is plenty for the room size, but I'm worried with the plasma I will need more.

If anyone with knowledge can help I'd appreciate it.

Thanks

I don't want to move the hot air round the room, I want to cool it.

I'm going to partly self install, an electrician friend will do the wiring, then the air con company will finish the piping and gas the system. Unit will be wall mounted on an exterior wall with the outside unit just the opposite side.

I didn't spend thousands on my Hi-fi and home cinema to play it quieter, I'm on a main road so having the windows open would mean I hear every car pass. I don't have it on all the time but half way through a movie the room is very hot. I think my body runs hotter than most too and I always prefer it cooler.

I heard the pre gassed units are illegal as to get the air out your have the purge the gas.

The newer pre charged units use quick connectors, so the lines are already vacced out and have a holding charge of refrigerant.

Thanks, the Mitsubishi SRK units are new but 2 installers told me they need special connectors, they said £100 if I part install it for them to finish it off.

Why not put that stuff into another room? Or are you a student?

I have a small flat, it costs me next to nothing, it's fully detached so no one complains if I play music very loud. I'll only move out when I can afford an attached house.

Thanks RJC, I will certainly try to install it myself first.

The supplier is Leicester air con, it's £384 for the 9000 BTU 2.6 Kw unit.

All done, just need to put some trunking over the pipes outside and I'm also thinking about making a cover, sort of like a radiator cover, just so the outdoor inverter looks nicer and blends in better.

Really happy with it, wasn't too hard to install and works perfectly, it can easily make it too cold so I set it to 22 C, I'll watch a film tomorrow and I'm pretty confident it will deal with all the equipment heat easily.

My system is single speed so the outdoor inverter runs flat out while it's on, luckily it only pulls about 700 watts and is very quiet. The indoor part varies the fan as required.
