Re: [EnergyPlus_Support] Simulation using HVAC Template with Reheat and Humidity Control
The heating.reheat coil does not have enough capacity. You have
specified 0.45 W. I changed the heating/reheat coil capacity to be as
large as the cooling coil capacity and it worked much better. Keep in
mind that when the zone moisture load is greater than the cooling coil's
latent capacity, the zone RH.will rise above the humidity set point and
a larger coil will be required.
Your file:
HVACTemplate:System:Unitary,
6200, !- Cooling Coil Capacity {W}
0.45, !- Heating Coil Capacity {W}
Corrected file:
HVACTemplate:System:Unitary,
6200, !- Cooling Coil Capacity {W}
6200, !- Heating Coil Capacity {W}
