Hello,
I'm sure there is something simple that I'm missing here. I'm trying to model a NECB 2015 code compliant reference building to compare with a new proposed building. I'm using openstudio 2.9. The proposed building is a mid-rise appartement building. We are currently evaluating the possibility to integrate air-to-air heat pumps to the project. I used the PTHP zone equipment to try to model this. I have no problem running the model with this equipment with default values and autosize. For the reference building I need to change the performance curves so that they respect NECB criteria. Here is my problem, most of NECB curves for the heat pumps are cubic like here:
But most of the PTHP curves inputs are quadratic or biquadratic like specified here for the DX heating coil.
What would be the approach to model these heat pump curves?
