Hi Chaps

You mean RWEYQ10M.You can connect indoor units with a total capacity of 34 kw.It is compatible with all types of VRV indoor units.The only issue about these units is that a tap water supply is not strong enough it must to be a commercial 24 l / s.

Thanks MRcoolingMAGIC. On the cooling capacity tables for RWEYQ10MY1 there are many capacities according to your conditions.This is a values of nominal capacities.What is the actual values?
this is my conditions combination 100%, Inlet water temp 30C,water volume 96 L/min, and 19 CWB Indoor air temp.
On this conditions the capacity of the unit is 26.7KW,this is the nominal capacity.I want to know what is the maximum capacity on this conditions.

Do u mean (sum of indoor units capacity/sum of outdoor units capacity)?

Tel you what dude sit down learn a bit theory before you proceed to these very complicated systems called VRV.It is not a domestic fridge.Sorry this is how i see it.;)

I found what is a combination ratio:
combination ratio=(Sum of Indoor units index/100% index of Outdoor)

That what I wanted. Thank u MRcoolingMAGIC.

Yes, But DAIKIN said the combination ratio does not exceed 100% (Recommended limit)

Wait wait, what do you mean by ( You can over index of course...).
As example RWEYQ10 100% index= 250.
You can not change this value in the formula(You can not use 110%...in the formula).But if you mean combination ratio over 100%; it is possible, but it is not recommended.

Heard you can over index up to 130%, due to not all indoor units bieng at 100% all at the same time. Be carefull of the refnet joints near the outdoor units,( within 2mtrs with an oil trap) and also if you are using it as an heat pump or heat recovery system, use the correct suction line fitting as one is 3/4 and one is 7/8, the also use a shared discharge and suction depending on the application! My advice is to read the installation guide at least twice... and don't throw any pipework connections away!
