Abstract

© 2012 Newswood Limited. All rights reserved. Water dispenser is one of potential energy saving household equipment which the Department of Alternative Energy Development and Efficiency (DEDE) wanted to find out the testing method and the values of Minimum Energy Performance (MEP) and High Energy Performance (HEP). The testing method from the Energy Star program in USA, Australia, Taiwan and Hong Kong are compared and composed to get the testing method for Thailand. The market survey is used to find amount of each types of water dispenser. By applying the Yamane statistical method, 30 and 32 samples of a cold and hot/cold water dispensers are tested. It is found out that the MEP of cold and hot/cold water dispensers are 0.46 and 2.91, for the HEP are in the range of 0.16 - 0.1 and 1.2 - 0.8 respectively. If all cold and hot/cold water dispensers below HEP can be upgraded to pass the HEP number, potential energy saving will be 1,247,312 and 4,564,789 kW-hr/year and CO2 reduction about 634,882 and 2,323,478 kg/year respectively. Final draft is also passed public hearing.
