[EnergyPlus_Support] DX coils consistency with ASHRAE 9.1-2007 Tab6.8.1A for a Baseline VAV system 5 with reheat
Dear all,
I have a question about how to model correctly a VAV system 5 of a baseline model in a LEED project.
My question is about how to set the DX cooling coil COP in the object Coil:Cooling:DX:SingleSpeed.
The object is set in this form.
Coil:Cooling:DX:SingleSpeed,
VAV-PC-01B AHU 4 Unitary Cooling Coil DX Cooling Coil, !- Name
On 24/7, !- Availability Schedule Name
autosize, !- Gross Rated Total Cooling Capacity {W}
autosize, !- Gross Rated Sensible Heat Ratio
2.87, !- Gross Rated Cooling COP {W/W}
autosize, !- Rated Air Flow Rate {m3/s}
773.300000, !- Rated Evaporator Fan Power Per Volume Flow Rate {W/(m3/s)}
VAV-PC-01B AHU 4 Mixed Air Outlet, !- Air Inlet Node Name
VAV-PC-01B AHU 4 Unitary Cooling Coil DX Cooling Coil Air Outlet Node, !- Air Outlet Node Name
DXClgCoilTotalClgCapFuncTemperature, !- Total Cooling Capacity Function of Temperature Curve Name
DXClgCoilTotalClgCapFuncFlowFraction, !- Total Cooling Capacity Function of Flow Fraction Curve Name
DXClgCoilEnergyInputRatioFuncTemperature, !- Energy Input Ratio Function of Temperature Curve Name
DXClgCoilEnergyInputRatioFuncFlowFraction, !- Energy Input Ratio Function of Flow Fraction Curve Name
DXCoilPartLoadFractionCorrelation, !- Part Load Fraction Correlation Curve Name
0.0, !- Nominal Time for Condensate Removal to Begin {s}
0.0, !- Ratio of Initial Moisture Evaporation Rate and Steady State Latent Capacity {dimensionless}
0.0, !- Maximum Cycling Rate {cycles/hr}
0.0, !- Latent Capacity Time Constant {s}
