We are trying to model a refrigerated/freezer warehouse in OpenStudio/EnergyPlus. We are using the ideal load scenario (Thermal zones section of OpenStudio). When running our model, we get a fatal error that results from the supply air temperature being set below freezing. The error file is listed below.
Has anyone encountered this problem before? Are you aware if we can input the supply temperature as below freezing?
Thanks in advance for your help.
