Hey guys we have recently (around 3 months ago) had Johnson Controls install a R134a chiller along with a new project my building was doing. Ever since it was installed it surges in multiple counts and sits and idles and vibrates almost sounding like it is running dry. The VGD surge count is like 30,000 already. Not a pro on this one yet and we are still awaiting training on this chiller, but this thing sounds like **** and need something to tell the boss. Lol.
We are running on a lower load condition right now and the veins are fully closed. We have VFDs installed on our pumps (condenser and chilled water) and they are not at max. Please school me on what is going on this damn thing is keeping me awake!
I will include any points or temps just ask. Thanks.
