If I use only one coil in the system and I would like it to be autosize. Am I doing it right there I am not very sure.
Coil:Cooling:DX:TwoStageWithHumidityControlMode,
DOAS Cooling Coil, !- Name
HVACTemplate-Always 1, !- Availability Schedule Name
DOAS Supply Fan Outlet, !- Air Inlet Node Name
DOAS Cooling Coil Outlet,!- Air Outlet Node Name
, !- Crankcase Heater Capacity {W}

Sizing:System, DOAS, !- AirLoop Name Sensible, !- Type of Load to Size On autosize, !- Design Outdoor Air Flow Rate {m3/s} 1.0, !- Minimum System Air Flow Ratio 2, !- Preheat Design Temperature {C} 0.008, !- Preheat Design Humidity Ratio {kgWater/kgDryAir} 11, !- Precool Design Temperature {C} 0.008, !- Precool Design Humidity Ratio {kgWater/kgDryAir} 16, !- Central Cooling Design Supply Air Temperature {C} 12.2, !- Central Heating Design Supply Air Temperature {C} NonCoincident, !- Sizing Option Yes, !- 100% Outdoor Air in Cooling Yes, !- 100% Outdoor Air in Heating 0.008, !- Central Cooling Design Supply Air Humidity Ratio {kgWater/kgDryAir} 0.003, !- Central Heating Design Supply Air Humidity Ratio {kgWater/kgDryAir} DesignDay, !- Cooling Design Air Flow Method 0, !- Cooling Design Air Flow Rate {m3/s} DesignDay, !- Heating Design Air Flow Method 0, !- Heating Design Air Flow Rate {m3/s} ZoneSum; !- System Outdoor Air Method
But Design Load is 76kW already but my coil only has 46kW
One more question is that in the Sizing:System I dont have any precool or preheat in the outdoor airduct what should I input there
