Hi, I'm new on TRNSYS to simulate water cooled chiller and cooling tower.

I try to import load, only temperature and flow then connect data to water cooled chiller, type 666 via "chilled water inlet temperature" and "chilled water flow rate" then connect chiller to cooling tower. My issue is that water flow that goes to cooling tower is constant: 110 000 kg/hr (default vaule) and water temperature of the return flow from cooling tower changed. But I want to fixed temperature at ~30oC and variable water flow to cooling tower.

So the question: Is there any automatic calculation to achieve this (variable flow and fixed temperature) or it has to do manual calculation of the flow via Equa tool then put this result to chiller via "cooling water flow rate".

Thanks.
