Development of cold-hot water dispenser with thermoelectric module systems

Abstract

In the present study, the results of a cold-hot water dispenser with a thermoelectric module system (TMS) are presented. The cold-hot water dispenser with thermoelectric module system consists of a cold water loop, a hot water loop, a coolant loop, and a thermoelectric module. The thermoelectric cooling and heating modules consist of four and two water blocks, nine and three thermoelectric plates, respectively. The cooling and heating capacities obtained from the cold-hot water dispenser with TMS are compared with those from a conventional cold-hot water dispenser with a compression refrigeration system (CRS). As compared with the conventional cold-hot water dispenser with CRS, the cold-hot water dispenser with TMS can be operated at the minimum cold water temperature of 10 to 13°C and the maximum hot water temperature of 65°C. The obtained results are expected provide guidelines to design cold-hot water dispensers with TMS.
