Chiller connection to condenser loop for ASHRAE 90.1 System 8 in OpenStudio

savecancel

Dear all,

I am wondering how I can add an additional chiller to the chilled water loop that connects to a condenser loop.

According to Table G3.1.3.7 in ASHRAE 90.1-2007 I need to have "2 water-cooled screw chillers sized equally". I read from another post that one way of adding a chiller which has a condenser loop is to use "VAV with Reheat" in OpenStudio and then modify the components. However, if I need 2 chillers how can I model it in OpenStudio?

When I try to drag a "Chiller Electric EIR" component to the system it doesn't come with a condenser loop. Is there a way to add one to it?

Thanks in Advance, Daniel
