EnergyPlus Crashed with Refrigeration

asked 2020-02-28 04:09:55 -0600

I have a complex simulation for a refrigerated warehouse. I have three refrigeration systems: the main one with nh3 and the other two of glycol and co2 that deliver cooling to the cold chambers at different temperatures. I think the problem appears due to the cascade condenser between the nh3 system and the co2 system at low temperature.

I replaced the cascade condenser with an air cooled one and it doesn't crash. I also tried linking the low temperature air chillers directly to the nh3 but it also crashes.

I am using OpenStudio but I share with you my IDF file because I think it is an EnergyPlus problem but I'm not able to debug the problem because the simulation crashes and the eplusout.err file doesn't give me any information.
