Synchronisation arises in dynamical systems that are composed of a number of interconnected subsystems. In the paper synchronization in a particular application a supermarket refrigeration system is studied. The temperature control in supermarket display cases is typically maintained by a number of distributed hysteresis controllers. Synchronization is then manifested by the opening and closing...

Refrigeration applications is responsible for approximately 17% of the total electricity and around 8% greenhouse gas emissions. This study presents a comparative life cycle assessment between two refrigeration systems, first operating with traditional fluid second natural refrigerant. The analysis was performed in accordance international standards ISO 14040/14044 adopted attributional approac...
