Condenser Loop Setpoint Manager

Postby MakiWatanabe » Thu Aug 10, 2017 9:34 am

Is it possible to stop condenser loop when the cooling demand is zero?
I found in my model, cooling tower and condenser pump is working during cold season; especially pump (constant flow, intermittent) is working full load 24 hours 365 days (electric consumption is same as rated power x 24 x 365).
Condenser loop availability schedule did not stop cooling tower and pump. I guess I need to edit condenser loop setpoint manager.
Which option of the schedule and what set can I make them working only when the cooling demand occurs?

Thank you.

I tried editing schedules in vain. It seems Condenser Loop works throughout the year anyway.
However I am writing this to inform that I found a fault; Capacity control of the cooling tower was converted to Fluid bypass in the exported IDF file, even though I choose 1-Fan cycling in DesignBuilder.
That affect the annual electricity use by the Heat Rejection, because the Cooling tower fan drives all the time, full power.
