1911 Published By: Blue Eyes Intelligence Engineering & Sciences Publication Retrieval Number F7920088619/2019©BEIESP DOI: 10.35940/ijeat.F7920.088619 Abstract: The steep rise in earth temperature also tends to rise in energy consumption for the sake of which demand for cooling also increases. Various cooling equipment’s are available within the market within different working principle, in which vapour compression system being the most common. But due to its design it is not easy to make it portable in which use of Peltier comes in place. Peltier being solid state in nature also has a benefit of being small in size as well it runs completely on Direct current. But due to lower efficiency of Peltier module the use is limited to some specific purpose. The heat dissipation of Peltier is higher than that of the absorption which intends require continuous removal of heat. For which liquid cooling outperform all in coefficient of performance. There are various coolants that can be incorporated within the system, in which water being the most common. So as per this research, water is compared to that of ethanol which being less common in terms of coolant. The study majorly concerned into various analytical part used for the calculation of COP of Peltier module in both the cases. Since our system doesn’t concern about overall system performance at present it is only concerned with the module efficiency so system COP was omitted in case of calculation and comparison. In the study it was obtained that for water and ethanol subjected to both natural and fan assisted radiator cooling a COP of 0.402, 0.413, 0.409 and 0.412 was obtained respectively for both coolant and cooling methods. Water was found the most suitable medium of cooling in regard to ethanol as due to tendency of heating up.
