Design and Development of Adaptable Hot and Cold Water Dispenser with Inbuilt Inverter for Rural Communities in Nigeria

摘要

Accessible hot and cold water dispenser is not common in rural communities in Nigeria. Most water dispensers are expensive for low-income earners especially in rural commu nities in Nigeria. In this work, an attempt is made to design a low-cost adaptable water dispenser with an inbuilt inverter for rural communities. The water dispenser was desig ned and fabricated using available materials found locally. The technique of refrigeration system was employed which include the use of a Peltier module and spring heating element made of nichrome to generate the cooling and heating effect, respectively. The temperature-time range for the hot and cold chamber was evaluated and it was observed that temperature increases with time in the hot chamber and decreases with time in the cold chamber.
