Dear Mike

      Your understanding about the flow rate is right. Since it is
impossible to control the chilled water flow rate through the chiller,
I wonder whether it is possible to control the water flow rate in coil
and how to set it up
      After I changed the chiller flow type to "ConstantFlow", I found
that the actual constant water flow rate in the results is neither
equal to the rated chiller volume flow rate nor the rated cycling pump
volume flow rate. So how did the programme determine the flow rate ?
      Thank you in advance
