Operating Cost Comparison Between Transcritical CO2 and Ammonia Recirculation Systems in a Cold Storage Warehouse
Author: Chris Herzog and Peter Lepschat
This paper examined operating costs of two similar cold storage facilities: one with a modern and efficient recirculated NH3 system, the other with a transcritical CO2 system. Analysis goes deeper than utility costs; other operating costs such as insurance, maintenance, personnel, compliance, water, chemical, and drainage are also reviewed.
