| Abstract | : | Drinking water dispenser has been a common sight in private properties and public places in Taiwan. Since tap water is only safe after boiling, drinking water dispenser has become a basic necessity. Another reason which makes drinking water dispenser favorable is the capability of providing various temperature of water that can be readily available on demand. Even though it is found to be convenient for user, providing various temperature of water that can be readily available on demand consumes a large amount of energy. Water dispenser contributes to 5.67% share of household electricity consumption in Taiwan [1]. These amount of shares make water dispenser the 5th most electricity-consuming household appliances after lighting systems, room air conditioner, refrigerator, and rice cooker [1]. High energy consumption on typical drinking water dispenser come from continuous process of heating and cooling to maintain water temperature in the tank. However, these continuous processes of cooling and heating may generate energy waste when there is no demand of drinking water at some periods of time. Although some water dispensers in market already provide scheduled energy-saving mode to reduce electricity consumption, this feature still need to be set manually by the user which may not optimally reduce energy waste. In public facilities, there are usually several water dispensers provided in the area while in private properties commonly only a single dispenser used. This condition makes energy waste generated from the usage of energy-inefficient water dispensing system in public facilities will be worse than in private properties. Besides creating energy waste when there is no actual demand at all, typical water dispensing system will perform continuous processes of cooling and heating on all water dispensers even though the demand of drinking water could be covered by only a few water dispensers available in the area and thus generating energy waste. According to conditions mentioned above, there is a need for a smart drinking water dispensing system that can automatically adapts to users’ behavior in purpose of energy conservation. |
