Water chiller systems
Pipe the boiler and water chiller as shown in Figure
16.
Install boiler, as shown, so chilled medium is piped
in parallel with heating boiler. Use appropriate valves
to prevent chilled medium from entering boiler. See
Figure 16 for typical installation of balancing valve
and check valve.
Install the flow/check valve in the boiler supply piping,
as shown in Figure 16, to prevent gravity circulation
during the cooling cycle.
If boiler is connected to heating coils located in air
handling units where they can be exposed to
refrigerated air, use flow control valves or other
automatic means to prevent gravity circulation
during cooling cycle.
