4.10 Setting up distribution condenser/subcooler
1. Start the circulation and open up all throttling valves to the fully open position.
If the circuit is capacity controlled, make sure the system is running at the
maximum flow.
2. Measure the individual flows and compare to the specified flows.
Measured total flow: m3/h or kg/s
If the flow notably deviates from the specified flow, search for the reason for this
deviation. Possible reasons can be pump, filter, valves, pipe length, air, gas, or
dirt in the system.
3. If the system has several condensers in parallel, follow the steps in section
Setting
up parallel units
to distribute the water correctly between all condensers.
Keep the throttling valve for the subcoolers fully open.
4. Measure the flow through the subcoolers and throttle the inlet valves to the
condensers until the specified flow is reached to each subcooler.
5. For several parallel units, check again the distribution.
Follow the steps in section
Setting up parallel units
.
6. Repeat until the specified flow is reached.
7. In case of higher flow than specified, throttle the condenser inlet more to increase
the flow in subcooler.
Note down all set and measured flows into a copy of the PI diagram.
