Abstract:

Energy recovery is not a new idea. Laboratories in engineering colleges consume a lot of energy for its operation. However, the energy consumed in the labs is mostly underutilized. Laboratories such as Heat Transfer lab, Heat Engine lab etc. convert the chemical energy and electricity into Thermal energy which is simply discarded by circulating cooling water. Although some of the energy lost is intrinsic to the nature of an engine and cannot be fully overcome (such as energy lost due to friction of moving parts), a large amount of energy can potentially be recovered. There is great scope in recovering wasted energy that takes the form of heat discharge from exhaust or cooling water, unburned fuel etc. In this work, the discarded thermal energy from Heat transfer lab is recovered using sensible heat storage media. The possibility of re-using spent liquids such as engine oil, vegetable oil as thermal storage media is investigated. The heat recovered can be used in heating water for domestic purposes. The 3D model was created using Catia V5.In our experiment we found that as the temperature of the inlet coolant increases, the amount of heat regained also increases. This system has a great scope in heat engine labs where thermal energy that can be regained is very high. Water when used as the storage media exhibited a better performance. Vegetable oil has a great potential since it has a higher recovery factor but its utilization factor is low.
