"Village Fridge"
prepared by
Engineering Students of SVIT College at VASAD.
In olden days, the train was run by coal. Now it runs by electricity. To prove the importance of coal the two engineering students have prepared a unique working model of a village fridge. First of all it makes surprise to us but it is true. Village fridge is prepared by two students studying in 3rd year Mechanical Engineering namely Ronak Shah and Nirav Modi. The fridge having total capacity of 185 ltrs costs around Rs.2500. As per the opinion of Ronak "the out look of this fridge is exactly the same as the domestic freeze. We have constructed the body of the fridge by using iron angles and iron fencing net. The body of fridge is supported by four feet of iron angles, which is covered by iron fencing net of two layers excluding the front side, keeping the space between the two layers ranging from 1 inch to 2 inch. In between two layers the coal is filled from top to bottom. We have put one bucket on the top of the fridge from which water passes through the pipes between the filled section of two layers of coal in order to keep coal continuously wet. Subsequently atmospheric air circulation takes place, so cooling effect is produced inside the fridge. We divide the inner portion of the body in three parts by fitting thermo coal sheet. As a result of the above process 15-degree temperature can be sustained inside the fridge".
Ronak and Nirav had prepared this village fridge to take part in PROJECT COMPETETION at the National level Tech fest named as "Village Fridge". Still today there are thousands of villages without electricity in our country. Hence the people of such villages do not use domestic freeze, which runs with electricity, so are deprived of benefit of the modern age freeze. Looking to this situation Ronak and Nirav thought to prepare fridge, which can be use by village peoples.
Nirav says, "We have compared the product of village fridge with domestic freeze. Our fridge is so successful than the domestic freeze in maintenance cost, operating cost and production cost. In domestic freeze power unit consumed 90 units per month and 1080 units per annum. If we calculate the cost @ Rs.4 per unit the power cost of domestic freeze would be Rs.4320 P.A, while in village fridge we can save this cost.
Due to low cost of this fridge village peoples as well as poor peoples of city can also afford this model in summer season also. Approx. 50 kgs. of coal consumed and lasted for 3 to 4 years, and then after it can be reused as fuel or any other way".
Further they told that in this model we cannot achieve 0 degree temperature. So we cannot get ice. People who are used to drinking chilled water they cannot get that much chilled water in this fridge, but this fridge is too much useful for preserve the Milk, Fruits, Vegetables and food in fresh condition.
