Thanks for the suggestion. I got the refrigeration object to work for my facility by looking at the Supermarket file. However, I have another quick question. My facility uses five ammonia compressors to service a freezer space kept at -20 F. Is it possible to design the compressor rack to have more than one compressor and service one case (i.e. the freezer for my facility)?

Thanks,

Dimos

All the 'Supermarket. .." example files have refrigerated cases. The most difficult part of the refrigerated case models is getting the case definitions right.

Subject: [EnergyPlus_ Support] refrigeration object

I was wondering if anyone could help me out with something. I am trying to model five ammonia compressors that service a a large refrigerated area (a freezer). Of the ammonia compressors, three of them are 200 Hp each, one is 400 Hp, and the other one is 75 Hp. Am I correct in using the Compressor Rack: Refrigerated Case object for this? Would I have to create a condenser loop? What example files involving a condenser loop or refrigeration object should I look at? I looked but I could not find one.

Thanks,

Dimos
