Hello, I am a beginner on Design Builder and modelling an ASHP for my university project. I have essentially used the DB template for an ASHP but have entered my own COPRFT and CAPRFT performance curves to model the DX coil. For my project I would like to show the variations in the ASHP COP throughout the year, however the COP remains pretty constant all the way though. Based on the performance curves I have entered there should be a clear degradation in COP when the outside temperatures drop in the winter months. Any ideas?
