Re: [EnergyPlus_Support] Re: Split type Inverted heat pump model with multiple indoor units



Waseem,
I have not seen curves with this discontinuity. It seems that you can use the normal low / high / boundary curves; in this case the boundary curve will be a vertical line.
I would test the results by reporting cooling capacity at each timestep and see whether you get correct results, especially at the boundary condition.
Let us know what you find, please.

Hi Richard and Jim, 

Thanks for your answers. I have another question regarding a same kind of system. What if there is discontinuity (a vertical straight small line) in Manufacturer's actual performance data, please find attached performance curves. The Y-axis is capacity correction factors, which is same as ratio of cooling/heating capacity, right? 

How to make curves in this case as it is different that we normally get for VRF system? Also, this values are at rated frequency, will that make any difference?

P.S. This is a split heat pump system. 

Thanks
