[aErOpLaNe911]

Can check do you mean those private air con company that inform you currently got supplies issue for all 24k BTU? Or big company itself like GC, Courts, HN, BD....also having supply issue?

Hi gurus


I'm looking to get a system 3 for my bedrooms (as highlighted on floor plan).
Like to get some advice on the configuration and brand to go for.
I see most recommending either Mitsubishi Electric for the serviceability or Daikin iSmile for ease of use.

Thanks

Anyone knows if there is any ex stock for Mitsubishi starmex 24k btu MUYGN24VA-MSYGN24VA anywhere?

Gain city just told me it is currently OOS world wide. Their website shows stock is available, but on the floor there isnt.

Looking to replace my existing ME Sys 3.

Considering a similar setup with sufficiently powered compressor but most of the quotes have only MXY3g28va2 which only has 20,470 BTU. Not enough to cool 3 rooms at the same time for 8 hours straight.

Advice please?

For cassette air cons, is it possible to change the casing ? Any idea?

It’s uncommon cos the total area quite small. One compressor can support usually.

If you want some redundancy, you can add 2 compressors. Pair MBR and 1 BR to 1 compressor and LR and 1 BR to the other compressor

Get the 4G38 compressor. Capacity is 7.4 kW.

Your room if all get FN10 need 2.8 kW x 3 equal 8.4 kW.

So it’s quite close but not too bad.

You only need the maximum capacity during start when cooling the room to desired temperature. Once hit desired temperature, very little capacity is required.

Planning to get 1 compressor for 1 MBR and 2 BR and another for 1 LR

Am I right to say MXY3g28va2 only have a total BTU of 20,470? Cos a contractor is claiming it have 28,000 BTU

Condenser, not compressor. Compressor is just a single part within the condenser unit.

4G38VA2 performance with 1x FN13, 3x FN10 - bold indicates fulfilled FCU performance
1x FN10 - 9.5K
1x FN13 - 11.9K
1x FN10 + 1x FN10 - 9.5K + 9.5K
1x FN10 + 1x FN13 - 9.5K + 11.9K
2x FN10 + 1x FN13 - 7.3K + 7.3K + 9.1K
3x FN10 - 7.9K + 7.9K + 7.9K
All units on: 5.6K + 5.6K + 5.6K + 7.0K

GC price is $5390, so $5.3k is okay provided the installer is good. Remember that aircon spec & brand is one thing, installation quality is also key. If $4.0k but installation like sai, I also don't want because down the line will give more problems.

Is better to pair 1 compressor to 2 fan coils to ensure maximum utility

Your compressor if pair to 1 MBR and 2 BR will need to get a higher capacity one

It has a maximum capacity of 8.9kW, approximately 30000 BTU.

The rated capacity is 6kW is 20742 BTU

The compressor is an inverter drive, it can vary the frequency to run the compressor faster but it’s not for extended period.

Dun look at the 28 of the 3G28VA2 to determine BTU. Look at the rated capacity in the catalogue

You should just call it outdoor unit. Condenser is just referring to one of the part of the the outdoor unit which is the condensing coil whereby the refrigerant condense back into liquid state from gaseous state. Compressor is also just a part.

Yep
Installation is where the money is spent ..
Don’t just go cheap ..

If I get mitsubishi electric, is the usual MXY3G28VA2 x 1 + MSXYFN10VE x 3 combo enough for the 3 rooms?

Same question here too, is gain city installation any good? I have existing installation and trunking and want to redo some parts of the placement, will they be able to do that?
