Effects of ambient temperature and thermostat setting position on water cooler energy consumption

Abstract

This research was aimed to studying the effects of ambient temperature and thermostatsetting on energy consumption of a water cooler. A 116 – W water cooler was tested in a laboratorywhere the ambient air temperature could be controlled. The experiments were designed toindividually investigate the effects of these two parameters and their combined effects on energyconsumption of the water cooler. Experimental results were analyzed by using Two Ways Analysis ofVariance and Multiple regression. It was found that thermostat setting has a greater effect on energyconsumption than the ambient air temperature. Furthermore, it was discovered that, for this watercooler, energy consumption increases 9.4% for each degree reduction in water temperature.
