Current model ( National ) 3 X Single split

10 years old

Conceal pipe

Inverter - Not sure ...maybe not

Electric Bill - $220

Inverter / Non Inverter

Choose inverter cos an inverter has a variable speed compressor.

The rotation speed frequency is regulated intelligently to meet specific cooling load requirement.

Power consumption is thus more efficient. My bills very high !!

Single / Multi ?

Any recommendation ...which is better ?

Conceal Pipe ?

Will probably get new ones ( Make new lines )

Heard that Mitsubishi is good for energy saving. Not just becos of Mr Liang Adverts.

Is that true. LG nice look Korea girls but not worth.

Mit is really quite popular - maybe because of the ads?? I also using Mit.

But stay far far away from LG, esp that artcool model. Nice to look at, not nice to use. Got so many complaints from this forum and also my own friends.

As for whether single/multi, I think it depends on the 'horsepower'. You can check out the 'aircon' blog here, think done by someone on this forum:

i am using mit non inverter starmex, personally used carrier, daikin, sanyo before. Carrier ok but outlook not very nice.

Daikin heard power consumption very high.

Sanyo very noisy.

Heard sharp compressor very noisy.

Quite amazed of the noise of the mit compressor produce.

And price within our budget so we go for it.

Conceal pipe as in the wall...can't see the pipe? it is not very advisable as it is very headache for u is anything wrong with the piping in future.

Thanks for all the info,

Just found out, difference of Multi / Single.

1. High initial cost

2. Cooling not affected by using all together

3. No savings in Elect, cos it depends on indoor unit ( KWH )

My requirment, is using all 3 rooms together ( 2 X 9000 ) + ( 1 X 12000 )

System 3 may not be able to cool all at 1 time.

Starmex do not have single inverter. ( strange ? )

Got some rough estimate ...

Inverter

Panasonic ( 2+1 ) = 2039+1049 = 3088

Mitsubishi ( 2+1 ) = 2099+929=3028 ( 1 = non inverter ) / (2+1) all non inv = 1679+929=2608

Mitsubishi ( Sys3 ) = 2879 ( total BTU 28,000 )

Non Inverter

Mitsubishi ( Sys3 ) = 2159 ( but total BTU only 20,000 ) means 776 or 866

maybe cannot cool the room

Est not include conceal pipe & stainless steel bracket

Try not switch on all your air-condition one short. Try to switch on one by one. so at least that the compressor wont take too much pressure and energy.

if possible switch on the furthest one from the compressor one first. then every 5 - 10 minutes on the other one.

If your requirement is to on all 3 rooms at the same time, then shd consider the 38K Starmex model instead of the 28K model. I am not sure whether u have space or current limitation.

Space no issue, currently 3 outdoors unit sits on the ledge.

What u mean by 38k model , salesman never offer that to me.
