4.2 Chilled-Hot Water Piping
Water supply and accommodation of expansion of the chilled water circuit is afforded
by either an open cistern or closed expansion tank with check/pressure reducing
valves as shown in figure 11.
Plan piping with a rising grade of 1/200. And where high points exist in the piping
circuit, install purge valves to expel trapped air.
