I am investigating how cooling tower outlet temperature setpoint affect to cooling consumption using the model with water cooled chiller+cooling tower.
In this study, I tried to change cooling tower setpoint from 21degC (case1) to 32degC (case2) using SetpointManager:Scheduled.
Even though case1 was operating as I expected checking chiller condenser inlet temperature, chiller condenser inlet temperature get over 40degC in winter season which I cannot explain why. (climate is Hong Kong) I checked cooling tower heat transfer rate, but seems working without problem.(refer to second image)
Could someone tell me what could be the reason causing this operation?
