Need some Aircon expert advises.

Daikin inverter system 3
Option 1
Indoor Unit: FTKS25DVM (9,000 BTU) x 3 Bedrooms
Outdoor Unit: 3MKS50FSG (20,000 BTU) x 1

Option 2
Indoor Unit: FTKS25DVM (9,000 BTU) x 3 Bedrooms
Outdoor Unit: 3MKS71FSG (24,000 BTU) x 1

- Price of 3MKS71FSG about $200 more
- HDB 5 rooms
- Master Bedroom and 2nd Bedroom aircon running for 4 hours only every night
- 3rd bed room rarely on.

I want to install 3MKS71FSG but wife want 3MKS50FSG (save electric bill).

My question is if only 2 units are running, will 3MKS71FSG (24,000 BTU) be running on same electric bill as 3MKS50FSG (20,000 BTU)?

If same... i would pay the $200 more and get the 3MKS71FSG.

Kind advise would be appreciated!

If based on 2 units running @ the same time, both outdoor units will consume around the same energy.
If 3 units, 3MKS50FSG will consume more.

I thought 3MKS71FSG should consume more energy? Cos it it 24,000 BTU?? 3MKS50FSG max BTU would be 20,000 BTU?

Daikin System 4 - 9,000 btu x 2 + 12,000 btu + 26,000 btu @ $4250. Is this price reasonable?

If 3 units are running at the same time, 3MKS50FSG is undersized, thus will consume more energy as the fancoil btu is around 6-7k btu instead of 9k, thus will take a longer time to cool down the room.

Hi,



1) 7.07 x 3412 = 24122 btu which is max 24k btu.
Thanks for clarification. But shouldn't I be looking at the max BTU figure for this configuration ie 6.61x3,412= 22.5k btu? Note that I'm planning to knock the common wall between BR & LR, to create a single studio space.

Also, my understanding of "Rated" power means aircon operating under standard/average conditions. If my room is particularly hot for eg, then the System2 will rev up to give its max cooling power (ie 22.5kW)?

TIA

The thermistor will feedback to the compressor to load up if the room is not cool enough or hot.

I have similarly gotten MKS80QVMG with CTKS25QVM x 3 and CTKS60QVM x 1. It works out to be slightly higher than yours, so I think your deal's quite reasonable.

I'm guessing you're getting the FTKM71PVM unit to cool your living room. R32 is a very modern refrigerant, nice. You're paying a pretty penny for mainly the additional condenser; but I guess if your house (and wallet) can take the additional current, I don't see why not.

Whatever you go for, it's much more important to ensure that the installation process is done correctly (see dachee's helpful posts). No point paying top dollar for a fancy A/C hardware only to have subpar workmanship and materials.

If similar price range, Panasonic will be a better choice.
