VRF Pipework Design

[al]

Is it 3 or 2 pipe VRF?

Is this the suction pipe?

If 3 pipe then the suction will remain suction, where would linear expansion come into it? ( am open to new knowledge btw, this isn't something i'v'e come across except on discharge lines?)

Hi Al,

Believe I've been looking into this too deeply. The pipe will on ever be a suction pipe, other being a liquid, this will not be a discharge line, so I would say I've looked at this wrongly, appreciate the input.
