We know liquid lines need to be bigger with R404A compared to R22 for the same duty, but is there also more puff down the hot gas/discharge pipe work too?
How does R404A compare to R407F?
Have heat recovery install and i suspect a bit more flow down the pipes to and from the reco will help keep the oil moving.
