Unitary System Performance

asked 2016-06-14 14:47:24 -0600

Cole.S's avatar

I have successfully cloned a Unitary System from a component model into an airloop, and inserted a setpoint manager, air terminal, and zone. However, I have received an error that I am not sure how to resolve. The error message reads:

"Cooling coil object type requires valid UnitarySystemPerformance:Multispeed for cooling to be specified with number of speeds > 0"

If anyone has some pointers on what is the main issue, that would be great.

Assuming the software is EnergyPlus, AirLoopHVAC:UnitarySystem object is missing Design Specification Multispeed Object Type and Design Specification Multispeed Object Name input fields and a corresponding UnitarySystemPerformance:Multispeed object.

Hi Chandan thank you for your response. I am having trouble inserting these objects. At first, I tried to manually update the .osc file to include these objects IAW with the bigladder unitarysystem definition. This proved to be unsuccessful. I tried to look through the OS API but cannot find a method that inserts this object. Perhaps I am looking in the wrong location. Do you know how to insert this object?

I reviewed the model sent to me offline and I believe this is a bug in the clone method for the coil. I have filed a bug here.
