Unexpected Latent Capacity in Air-Chiller Coil for Refrigerated Warehouse Model

edit

Hello everyone,

I am -still- trying to model a refrigerated warehouse in EnergyPlus using the AirChiller object with the following rating conditions:

The model has no fresh air supply, no infiltration, no people, no defrost, and no internal loads. Given these conditions, I expected no latent load in the system. However, the simulation results show that the air-chiller coil has a latent capacity, as indicated in the attached figure.

Any idea what might be causing the coil's latent capacity? Any suggestions for troubleshooting or correcting this issue would be greatly appreciated.

Thank you!
