Experimental Analysis on Solar Operated Thermoelectric Refrigeration System

A refrigerator is a common house hold appliance that consists of a thermally insulated compartment and a heat pump that transfer heat from the inside of the refrigerator to its surrounding so that the inside of the refrigerator is cooled to a temperature below the ambient temperature of the room. Thermoelectric Cooling (TEC) solar refrigerator runs on energy provided by sun, which includes photovoltaic or solar thermal energy. Peltier Jean (1834) discovered the Thermoelectric (TE) property about two centuries ago; thermoelectric device have commercialized during recent years. The applications of TE vary from small to large refrigerators. The Thermoelectric module refrigerator work on the principle of Peltier effect. Recently, the application of TEC modules in an industry is dramatically increased. . The main objective of our project is to design& make analysis of a Heating& Cooling system which utilizes non-conventional energy source (i. e. Solar Energy) with the help of Thermoelectric Module which works on the principle of the Peltier effect. This will be a suitable& affordable system for the people living in remote part of India where load-shading is a major problem. The major difference between the existing system& our system is that, our project works without use of mechanical device& without refrigerant too. As the module is compact in size one can design (i. e. shape, capacity) the system according to his requirement. In this paper an attempt has been made to conduct an experimental study on small scale solar operated thermoelectric Heating& Cooling system.
