Autosized FCU not Cooling the Space
I'm running simulation in EnergyPlus (Design Builder) The cooling coil & fan are operating during designated hours, and the coil is set to autosize so theoretically it should be sized however big it needs to be to cool the space to setpoint? However the result shows ridiculously high operative temperature, as shown in the attached graph.
- Cooling setpoint: 22 Degrees
- Cooling setback: 23 Degrees
- Coil & Chiller are autosizing
- Fan is operating normally
- Temperature control is set to Operative Temperature
- The output shows an operative temperature at 30 Degrees and mean air temperature at 25 Degrees
- Radiant Load 2.6kW
- Cooling rate 2.3kW (This is why it's not cooling, but why doesn't the system autosize the cooling rate higher?)
Any ideas how I can troubleshoot this?
@y.li@22degrees.co.nz what simulation tool are you using? Please mention it in the title or body of your post, as well as add a tag so that others can provide better help.
