This document provides methods for establishing the design or intended inventory of refrigerant for a given industrial refrigeration system. It also provides guidance on dynamically tracking the refrigerant inventory in refrigeration systems as a means of alerting plant personnel to refrigerant losses that may be occurring. Finally, this document provides approaches that can be used for identifying locations where fugitive emissions of ammonia from refrigeration systems may be occurring.
