Placing the aircon

Hi all

I have read a lot about aircons in this construction forum.

We are going to the Philippines for an extended vacation and want an aircon installed in the bedroom so we can have good rest.
Since we will not spend very much time there for the next few years I think LG would be a good choice price/qualitywise.

The room is long and narrow. I wonder if anybody could advise us on where to install the unit. Should it be on a long wall or on the short wall?

My first guess would be on the long wall right over the bed that's located in the middle of the long wall. This way it would blow over the bed, not directly at the bed. But I really don't have any experience.

The room is app. 15sqm, not well isolated.

I am looking for the

LG LS-Q 096 with 9000 BTU or maybe

LG LS-R 126 with 12000 BTU

But I believe 9000 BTU should be enough. They have both a setting for mainly reducing the humidity without doing too much cooling which I believe is a good thing.

Grateful for any advice

My LG experience:

I bought 4 LG's and was sorely disappointed. They all have the same problem. As the plastic expand and contract with the heat of the day and the cool of the night they begin to shake rattle and toll ruining any chance of getting a good nights rest. After 6 months of unsuccessful service calls, LG sent out a tech that said it is a problem with all their designs. He took them all apart and fitted little spacers and rubbers all about the machines to stop the noise. I have 1 Mitsu that is a great machine. Quiet and cools the room perfectly.

You can use silicon to stop any rattles

put some where the rattle is, leave the plastic bit off for a day, then put back and no rattles

Thanks for the warning and for the tip. Will the silicone have contact with the inner casing or just dampen the vibrations?

If the first is the case it may be a good idea to put some plastic wrapping on the fresh silicone to avoid sticking and put the cover back on immediately.

The positioning of the air-con wall mounted unit will largely depend on the water flow out point and the positioning of the outdoor compressor. Make sure the compressor is in a shaded area.

You should keep your water drainage pipes as short as possible and also make sure they have enough flow-off angle.

Placing an airconditioner over the bed will always risk the chance of condensation drops leaking onto the bed.

I always use Daikin, energy rated air-cons and know nothing about LG products.

:durh: Forgot that one completely.

Little choice there. It is either south or west, so it goes west, near to the neighbour. It will have shade from the neighbours house in the evening.

it acts as a damper between two surfaces that were touching

you can do it your way, with a bit of clingfilm to stop sticking, but it may flatten out too much

Hi
Got an Aircon. It is a Panasonic after all. Got a good deal including installation. It's not an inverter unit but has an EER of 2.85 which is reasonable.

I love the dry feature. If there is rain it is not hot but extremely humid. Taking out the humidity is not energyconsuming but makes it so much more comfortable.

Happy now!

I under airconed, don't do it. I got Mitzubishis, very quiet but shit. Ok at night but in the day garbage! If you need 9000 btu get 12000.

I would think you would want to place it on the short outside wall so that it can blow down the length of the space. The unit certainly seems large enough to cool the entire space.

The last AC unit I bought was an LG unit which has been very satisfactory and has been in operation about three years now. They even sent me a 30 page English owner’s manual at no extra charge.

In Thailand I have had satisfactory results with Hitachi, Mitsbishi and Daikin. (Daikin are manufactured locally).

In the Middle East I have installed many split units, always Mitsubishi.

As said above - go to one size larger than absolutely needed, as you can always lower the output, but can never get more than it's designed for, so that if you need a rapid cool, you are buggered if the equipment is not man enough.

I finished up with 4 Samsung units. Very quiet inside and out. Local man from village that fitted them comes back once a year and cleans them out for free.Don't know how long that will last!:rolleyes:

good thread.

we have a couple of units we salvaged. they were working fine when we got them but they have been in storage for a year now.

i am fairly sure that a recharge and clean out will be about all that will be needed to get them working again. does anyone have any experience with re-installing a used unit?

the design of our place is such that the compressor will need to be located about 2 - 3 meters lower than the inside fan part, and the run of the 'input' (for lack of a better term), pipe will subsequently be long as well. aside from insulation will there be any other considerations about that?

the water drain is good to consider. we don't have that as a problem, i think, but good to consider.

Yes. Just got some local changs to install it. It works well when we use it, but I rarely do. The climate in Udon is cool enough not to need it if you've got a couple of fans.

You'll be OK.
