Multi-split design

Several rooms, one outdoor unit, designed properly

Group the rooms that share a condenser and Vento checks the combination ratio, diversity, pipe limits and refrigerant charge against the manufacturer’s data — then draws it.

How it works

1
Size every room
Each room on the job is measured and its load worked out.
2
Group the system
Assign rooms to a multi-split system and pick the outdoor unit.
3
See the drawing
The shared-condenser drawing shows every pipe run, floor by floor.

The details

Checked, not guessed

Combination ratio, simultaneous load, pipe lengths and height difference are checked.

Charge worked out

Total pipe length and the refrigerant charge come from the placed geometry.

Mixed brands caught

Indoor units from a different manufacturer to the condenser are flagged.

What it won’t do. Checks use the manufacturer data held for each condenser. Confirm final figures against the manufacturer’s installation manual.

Frequently asked questions

Can I mix brands on one outdoor unit?

No. A multi-split is one refrigerant circuit, so Vento flags indoor units from a different manufacturer.

Does it work across floors?

Yes. Rooms can sit on different floors, and the drawing shows each floor.
