Hi all
Hoping you can help point me in the right direction please as I don't have much experience with water chillers.
I was called out to a set of chillers which have water cooled condensers which are fed from a cooling tower. The chillers are tripping out on HP. The flow seems to be fine but I noticed that the chiller closest to the water pump had colder water going in than the next along. I then found a high point in the water pipe and opened and purged loads of air. This helped with the water temperature but the second chiller is still tripping out.
I think there is still air getting in. My question is how do you find the air leak, I'm guessing on negative pressure side? Any other pointers to check?
By the way the water pressure gauges throughout don't work so bit tough to test.
Thanks for your help
Carl
