I see them now.  Thanks, Brent.

The outdoor units for VRF do have part load correction curves, separate for cooling and heating.  But VRF systems tend to unload nicely and it probably is okay to just use null 1.0 curves in many cases.

Good question - one I don't know the answer to.  That occurred to me the other day; most systems in E+ have part load performance curves, but VRF does not.

Hi Jim, 

I will give it a shot and will update here. 

Also, I don't have part load performance data, can I get away without it in VRF systems?

 

Thanks

Kindest Regards

Waseem
