Refrigerant line connections

Piping

Maximum distances and refrigerant
line diameters between units must be
checked according to the
configuration and system operating
conditions (Chilled water
temperature and subcooling).
Tables 12-14 provide the maximum
acceptable height according to
subcooling available and
recommended diameters for
discharge liquid lines when CCUN
condenserless chillers are connected
to remote condensers.
