[Dsg-hallc_nps] Chiller flow question

[Aaron Brown]

Hi Alexandre,

It is my understanding that the pressure and flow for these chillers are not controllable.
You can set the temperature only.

There is a GUI that shows the chiller's temperature and pressure
[cid:84b9f932-cfb7-4e8d-b022-112221e17739]

There is, as far as we've been able to tell, no flow readout from the chiller itself.
To remedy this, we installed external flow meters on both chillers that provide the temperature, pressure, and flow.
You can access this info via the chiller coolant screen.

I hope this is helpful.
Let me know if you have any more questions/concerns.

Best,
Aaron

Hi Aaron,



Is there a way to increase the NPS chiller flow ? I only see temperature and pressure on the GUI ?



If we increase pressure would that increase the flow ? How high in pressure has the system been tested ?



Thank you,



Alexande
