YK Surge Troubleshooting: Chiller Training

In this chiller training I walk through a YK centrifugal chiller surge troubleshoot. Chiller technicians and chiller mechanics need to understand how to troubleshoot this critical condition to protect their chiller. Full version of training at chilleracademy.com where you can also join the conversation in the chiller community.

Hows it going Holden
I was wondering if you have any feedback or experience on an issue that’s been reoccurring at a plant I’m working at. Our York centrifugal chiller every now and then, while it’s regenerating at night & after running for a few hours, it shuts off on an alarm indicator displaying “ vane motor switch open”. It’s an odd thing I’m not sure if it’s a panel issue, program issue or what, Any experience on this?

What about the VGD?

[@HVACTIME]

While the VGD can help in a surging condition. The best path is to correct the conditions causing the surge state.
