Aircon unit for home.

[Trevor555]

Hi all,

Need aircon units fitted to bedroom & lounge.

We made do with the portable ones last year where the tube goes out of the window.

Looking for proper wall mounted ones now.

Question?

Do they all have the big fan units that goes outside?

Recommendations welcome.

Ours do. I assume they all do. We have 4 rooms with air con and three outdoor units.

ETA here they are going in in 2006

We've got 4 bedrooms with a unit in & 2 in the front room/extension fed from 2 external units.

Best thing we ever did. Year round temperature control.

Do it!

What you’re referring to is known as a “split” AC unit and yes, as well as the wall mounted internal unit, you’ll need an external condenser unit. In simple terms, this is the unit that expels the heat from the refrigeration cycle, allowing the internal to ‘blow cold’…..or indeed, allows your indoor unit to blow warm by working in reverse and absorbing heat from the outside air.

However, depending on the approach you go for, it doesn’t have to be a 1:1 ratio of internal to external units. You can opt for a what is known as a ‘multi split’ system, where by multiple indoor units can be fed from a single outdoor unit. Ratios can be as high as 4:1 (indoor to outdoor), but the unit will then be quite large. However, if you’re looking to minimise outdoor units, this could be an option.

If your not au fait in this area (which, based on nature of the question I am suspecting you are not), find a local domestic AC firm who can talk you through it, because multi splits in particular can get a little more technical in terms of sizing etc.

We have this. A *5/6kw output unit for the lounge, a 2.5/3.2 kw unit for the bedroom.

Took about 5 hours to be installed, and look neat. Work a treat, almost silent on auto mode. Pretty standard off the shelf stuff.

• The figures are output/cooling capacity,active power use 500 - 1700w for the big one, 300-1300 fpor the smaller.

Big

Small


Outside

Thanks all,

As I suspected, we'll have to have a unit on the outside then.

You can get units which are essentially wall-mounted versions of the portable air conditioners, with the vent pipe venting straight from a hole in the wall behind the unit rather than through a window or whatever. They tend to be noisier and bulkier inside the house than split units though, and require drilling bigger holes in the wall (or often two).

That's just what I need, thanks for that.

Just to be clear, you’ll get no where near the output, efficiency, reliability, after sales or noise levels from one of those ‘all in one’ type units.

The ‘tried and tested’ major international AC manufacturers likes of Daikin, Mitsubishi, Samsung, LG and Fujitsu do not manufacturer/sell that type of unit, for good reason.

It may very well be all you can fit/install in your specific application, but do bear in mind the compromises -especially in a bedroom environment. In fact, i’d suggest you may as well keep your portable units.

Yes I think they are very similar in performance, noise, etc. to the portable ones so the advantage is just neatness really.

I can understand the noise aspect, but why do two boxes connected by pipes work better than one box without pipes?

I think there's a few reasons. Firstly the condenser of a split unit is usually far bigger than anything you can realistically put in a combined one; secondly you can get a LOT more ambient air-flow over an external condenser than one which is built into an internal box pulling air through pipes, and thirdly (albeit a minor one) you ideally want cool air generated near the ceiling since hot air rises.

ETA: I'm not really sure why they'd be less reliable.

As others have said the actual AC install is pretty easy, the outside unit I believe is one that will need most of the servicing so the unit in the room itself is pretty much maintenence free? The actual hole drilled into the room isn't very undisruptive as it just need to accommodate some pipe work, on ours we didn't need to worry about a power supply for the indoor unit as it takes power from the out door unit.

The all-in-one unit in the link looks pretty messy to install, it look like you need two pretty big holes in the wall, the Amazon reviews aren't exactly glowing.
