New Delhi, March 12 -- Refrigerators, unlike other home appliances such as ACs, geysers and room heaters, are used all year long. In the summer, they give us ice cubes and cold water, and keep food from getting spoiled, and in winters they keep the food fresh. Smart refrigerators go a step ahead. They give us an inventory of the food inside and the supplies that we are running low on without opening the door. They also tell us all the dishes that can be made using the available food items and act as a hub for family communications. Needless to say that smart refrigerators make life, or at least kitchen management, a tad bit simpler. So, if you are planning to give your kitchen an upgrade now would be a good time to do so.
