Since some years, European companies are interested in the issue of energy saving. In such context, a classification of industrial machines from the energetic point of view is becoming more and more important; currently, in the industrial context, no similar classifications exist. The aim of this work is to formulate a standard method to evaluate the energy performance of an industrial machine, such as a shrinkwrap-packer. To this purpose, we studied a shrinkwrap-packer produced by OCME S.r.l, a mechanical machinery company located in Parma (Italy). Specifically, the shrinkwrap-packer was analyzed in terms of energy dissipations and other aspects related to the energy source utilized to power the oven. As a result, we propose a general procedure that allows to compare different solutions from different perspectives related to energy efficiency. More precisely, we include three key performance indicators (KPIs) of energy efficiency, to build a comprehensive evaluation model. The first KPI concerns the energy efficiency class of the oven, the second KPI takes into account the impact of the oven on the work environment and the third one is an index of degradation of the energy resource utilized. A Global Index of Energy Efficiency (GI) is finally computed as the area of a triangle represented on a radar diagram on three axes, one for each KPI.

Abstract
Since some years, European companies are interested in the issue of energy saving. In such context, a classification of industrial machines from the energetic point of view is becoming more and more important; currently, in the industrial context, no similar classifications exist. The aim of this work is to formulate a standard method to evaluate the energy performance of an industrial machine, such as a shrinkwrap-packer. To this purpose, we studied a shrinkwrap-packer produced by OCME S.r.l, a mechanical machinery company located in Parma (Italy). Specifically, the shrinkwrap-packer was analyzed in terms of energy dissipations and other aspects related to the energy source utilized to power the oven. As a result, we propose a general procedure that allows to compare different solutions from different perspectives related to energy efficiency. More precisely, we include three key performance indicators (KPIs) of energy efficiency, to build a comprehensive evaluation model. The first KPI concerns the energy efficiency class of the oven, the second KPI takes into account the impact of the oven on the work environment and the third one is an index of degradation of the energy resource utilized. A Global Index of Energy Efficiency (GI) is finally computed as the area of a triangle represented on a radar diagram on three axes, one for each KPI.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
