thank you friend.can you also tell me how the water comes out in three varieties.,,hot,cold and normal.how the heating and cooling process takes place inside the machine

Answer 4

The magic behind it is the use of heat exchangers .....below i have posted simple schematic diagrams :
1) cooling process
2)heating process
to get normal water you just have to get the water after all purification and give it to outlet.....remember HEAT TRANSFER TAKES PLACE FROM BODY AT HIGHER TEMPERATURE TO BODY AT LOWER TEMPERATURE.......
