REVIEW ON THERMOELECTRIC COOLING : MODELLING AND ITS APPLICATION

Electrical Engineering

Increasing demand for cooling in field of air-conditioning, refrigeration, vaccine storage and food preservation lead to emission of more CFC gas and more consumption of electricity. Thermoelectric cooling is the new alternative because when it is supplied with dc supply it creates temperature difference as an output, without any environmental effect [1]. Effectively we are using TEC systems having advantages over the alternatives present till date, such as light in weight, high reliability, compact in size no mechanical moving parts and no working fluids. Peltier effect of thermoelectric cooling is the concept under which the cooling operation is going to be done. In this paper the study on the thermoelectric cooling using Peltier devices with the précised output, results has been obtained [3]. Also with hardware modelling of medication box to store medicines so as to maintain their potentiancy and effectiveness which will hold a major contribution in medical applications. As seen from the previous years, with the increase in the population the chances of the diseases and the accidents have been increased. It became necessary that the cure for this event, disease or an accident, must available on time when required. This paper deals with the concept that will help to store these lifesaving medicines in a more efficient way [5]. Different medicines need different temperatures for storage to maintain its potentiancy and effectiveness, some may need cold storage some may need probably high temperature. Considering all these in mind we have designed and fabricate thermoelectric cooling system having advantages over conventional cooling devices, such as compact size, light in weight, high reliability, no mechanical moving parts, no working fluids and eco-friendly. This model i.e. smart thermoelectric medication box holds tremendous advantages over available traditional alternatives.
