Performance monitoring strategies for effective running of commercial refrigeration systems

Refrigeration systems often represent the largest electricity consumers in the supermarkets. Therefore there is a clear need for running these systems effectively. Performance monitoring uses different techniques to determine the actual system state. Another motivation for such monitoring is the existence of directives and regulations applying both to food manipulation and system equipment. Following article is devoted to state-of-art performance monitoring methods in commercial refrigeration systems and describes some of the challenges in the applications of these methods. Energy monitoring, as closely related topic, is described in a separate section.
