VRF schematics

[terminator]

Hello guys,

Despite being in the trade for many years, I've never had much experience on vrf/vrv's. I've installed countless splits and multi-splits, but only one 2 pipe Hitachi vrf using simple refnets, no bp boxes, or anything complicated.

Is there a site where I can download / view a decent diagram which shows exactly how the refrigerant flows and is controlled etc.

I'm keen to become proficient on these systems.

Thanks for your time.

G.

Do you try Hitoolkit?

You can register on most the main manufucturers web sites & then down load the installation & service manuals.
Most of what you can learn about the systems is contained in the manuals.

After that consider getting on the training courses.
Some manufactures only provide free training for contractors who purchase lots of kit but others provide some free training.
Most do a basic installation & commissioning course for installation engineers.
Really the refrigerant flow is the easy part to understand, its the electronic control that gets a bit more involved.

I can help you out. Can you send me a rough schematic so that I can do this properly for you?
