Low pressure systems such as the YZ chiller operate
at pressures below atmospheric pressure. This means
that any leaks will suck air into the system. Air is non-
condensable and therefore interferes with the refrig-
eration cycle causing high head and poor heat transfer.
The purge system monitors for air in the system and re-
moves it. This screen displays a view of the purge sys-
tem. Setpoints relating to the purge system are shown
on this page as well as the chiller parameters affect-
ing the purge cycle. The YZ purge system monitors the
chiller conditions to diagnose when non-condensables
are present and then remove them from the system.
