GOLD GV Water boiler series 3 — manual
IIIj Water piping — water chiller systems
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.
