Temperature Selective Based Locomotive Water Dispenser

Trains are equipped with water lines in all compartments, but not drinkable. This new approach helps the water drinkable by purification of the water from the lines with a separate provision to purify it, the new system obtains the purified water and stores in an overhead tank. The consumer has the choice of choosing the quantity&temperature of water. Choosing the inputs by the consumer, the quantity&nature of water is decided and sent to the microcontroller. Then with multiples of Rs.5 as activation key for the process to start, the choice of temperature is chosen as warm or cold or plain&the respective tanks are opened and closed to obtain the preferred water temperature and quantity. The whole system of temperature preference is with the mixing of water at various temperatures. The heating&cooling process of the water is the same traditional methods but the attainment of specific temperature is by the heat&mass transfer principles of water. This system is motived to be implemented on railways because of surplus water availability, a good source of income to the government and to avoid the usage of plastics in any form to store water.
