Energy Efficiency of Washing Machines

This paper makes a technical analysis of the methods to increase the energy efficiency of washing machines for student education. Starting from the definition given by the Energy Efficiency Index, the present analysis proposes two methods for increasing the energy efficiency of the washing machines by modifying the standard annual energy consumption (SAEc) and by modifying the annual energy consumption (AEc). These two methods are made per kilogram of clothes for washing machines from the same brand in different energy classes and for washing machines of two different brands. The models analyzed were chosen according to their energy rating A++ and A+++. The results of this analysis propose the energy savings as an energy indicator to inform buyers in choosing a brand and energy class of the washing machine.
