Hi Guys
I am bit unsure on how to run the dry cooler and the chiller.
I have attached the setup.
The idea is to cool the water using the dry cooler (as much as possible).
When the ambient temperature is high and the dry cooler no longer can hold the temperature, a chiller is used to help or fully cool down the water.
My idea was to do the following:
The temperature at TT4 must always be lower than than a given setpoint (SP).
So we could say:
TT4 > Setpoint
If the TT4 is higher than setpoint then start the chiller and maintain setpoint.
In addition, IF
TT2 > TT1 then fully close port B
That would enable us to directly go to chiller operation if the dry cooler can no longer hold the temperature.
The issue is only, if the ambient temperature falls again, then I want to go back to using the dry cooler.
However, as I see it, there is no flow through TT2, then how will I pick it up?
Please let me know if there any smart way to do this!
