Hi ALL, In simulating my chilled water system (with Fan coil unit
using variable speed fan and cooling coil; cooling tower using constant pump),
I connected my equipment to my building model. The system runs and I managed to
obtain the zone properties (i.e temp and RH). However my chiller shows a
constant data (i.e. const flow rate, power, heat rejection etc) throughout the
simulation, even though I used variable speed pump for my chilled water. I am expecting the chiller data to vary according to the
cooling load of my building. So my question is, by connecting the cooling
equipment to my building, will it recognize the different building loads? Or can I alternatively use Type682 to obtain the building
loads and connect it to my chiller system to check its performance? And if I
were to use this approach, how do I determine the zone properties of my building
during cooling. Or any advice on what may be missing from my original model. Note: I am using the sample catalog available in TRNSYS for
my chiller. Any help is deeply appreciated. Nguan Teck NTU, Singapore |
