Commissioning the Water Flow
Precautions
For details about how to commission the liquid flow, see the documents provided by the CDU manufacturer. This section is for reference only.
Procedure
- Open two automatic exhaust valves on the secondary pipe system and use the CDU manual water refill function to inject glycol solution to the secondary system.
- Exhaust air.
Ensure that liquid in the make-up container is sufficient. After the CDU stops filling water (automatically stops when PS1 = 1.0 bar), start the CDU for 1 minute and stop the CDU for 1 minute. Repeat this cycle for several times.
- Open the supply and return water valves on the primary side, adjust the valve opening to 100%, and check whether the meter reading on the primary side meets the requirements.
- Check whether the readings on the secondary side meet the heat dissipation requirements.
- Commission the CDU.
