Multiple temperature selection thermoelectric water dispenser

With the limited water temperature dispensed by current water dispensers and the varying water temperature desired by consumers, a multiple temperature selections thermoelectric water dispenser was designed to provide the consumer’s demand. This design uses a Thermoelectric module that operates based on the Peltier effect to heat and cool the water in the respective container, thereby eliminating the harmful effects of Freon, a refrigerant used by the current water dispensers process. Arduino Uno’s implementation as a microcontroller provided consumers with a chance to input and be served with their desired water temperature. The experiment results showed that the design is accurate in providing the consumers with their desired water temperature. Thus, the implemented design is successful in meeting the objectives of the study
