I have model which implement following components for HVAC system (with autosize for capacity) 

HVACTemplate:Zone:VRF
HVACTemplate:System:VRF
HVACTemplate:System:DedicatedOutdoorAir

When I look at the HVAC Sizing Summary, the sum of total User Design Load[W] is 674.4kW.
On the other hand, the sum of total Nominal Total Capacity in Cooling Coils and DX Cooling Coils are 162.9+168.4kW, which is much smaller than abeve-mentioned User Design Load[W]

Can anyone tell me why this happens?
In other words, how EnergyPlus calculate coil capacity according to HVAC sizing?
