Effect of Load, Time and Temperature of Water on Water Consumption and Electrical Energy Consumption of Washing Machine: An Experimental Study

Due to the depletion of water level and increasing of energy demand, there is a need for energy efficient system increasing in recent years. In this paper, the variation of water consumption and electrical energy consumption caused by load, the temperature of water and time in a top loaded vertical axis portable washing machine and the outcomes this study are also discussed. A 3kg of DMR mini wash (model: DMR 30-1208) was used in this study. An experimental study was conducted with three different loads (i.e. 1kg, 2kg and 3kg), three different operating times (i.e. 1hr, 2hrs and 3hrs) and three different water temperatures (30°C, 40°C and 50°C). The experimental results revealed that the consumption of water increased with an increase of load and time also it decreased with an increase of water temperature also the electrical energy consumption increased with an increase of load, time and water temperature.
