I'm looking for a software tool to model a refrigeration system for a cold storage facility. I need to create a baseline then model a VSD retrofit to the compressor. I have used Equest before but the refrigeration version doesn't have any wizard and requires a lot of details on the existing system and I'm not a refrigeration expert. Is there a simpler quicker tool that one can use to model the refrigeration system that includes a wizard? I'm really looking for a simple tool to model the energy consumption, not looking for any design orientated tool. Any help would be appreciated.
