Concept of thermoelectric (TE) energy makes it unique because of reversible energy conversion, e.g. from thermal to electrical and vice-versa. Seebeck and Peltier effects are base of all TE energy applications. Thermoelectricity has wide range of applications due to reversible energy conversion. In recent years, with technology development and global warming issues TE devices come into use in various applications because of its eco-friendly feature and distinct advantages. The thermoelectric energy has a vast range of applications in various fields like; electricity generation, refrigeration, air conditioning, particular heating/cooling, biomedical devices etc. due to its simple construction and mechanism, portability, require DC supply to run etc. This research paper thoroughly reviews the recent development and research work carried out by many researchers on thermoelectric energy applications in areas such as; power generation, refrigeration, electronic device cooling, automobile air conditioning & systems cooling, air cooling, medical field applications etc. Keywords: Thermoelectric, thermoelectric energy, application of thermoelectric, thermoelectric cooling, thermoelectric refrigerator, thermoelectric generator I. INTRODUCTIONWorld's energy demand is continuously increasing day by day and convention source of energy have limited stock. Also, conventional sources of energy have many issues of carbon emission; it is main cause of global warming. The thermoelectric (TE) system is quite suitable due to its renewable energy feature (means no carbon emission) and eco-friendly behaviour. Emissions of greenhouse gases are increasing globally because of continuous increase in demand of electricity, heating and cooling, refrigeration and air conditioning etc. Only green technologies such as wind power, solar power and other renewable energy sources can control the emission of greenhouse gases and play important role for sustainable development. Many countries are trying to control emission of carbon by forming new rules for industries. In recent few years, thermoelectric equipments have come out with potential as alternative eco-friendly applications. Applications of thermoelectric energy extended in various areas such cooling or heating, refrigeration, electricity generation, ventilation, air conditioning etc. due to its eco-friendly features and distinct advantages. Thermoelectric energy has potential to convert thermal energy into electrical energy and vice-versa. Due to solid state (no fluid/rotating part) mechanism of thermoelectric devices, it has variety of small applications for cooling of central processing units (CPU) and produce electricity in automobiles from waste heat [1].

“…For CI engines, it is assumed that the share of thermal energy loss in the exhaust gas is a maximum of 35% [16]. For this reason, systems are developed and implemented that work in the Clausius-Rankine cycle as well as thermoelectric generators for automotive applications ATEG [17][18][19][20][21]. At a conference organized by German Institute of Automotive Engineering IAV in 2014, Iriyama [22] the representative of Toyota Motor Corporation, presented the company's strategy for reduction of fuel consumption in order to comply with the increasingly stringent CO 2 emission limits.…”

Abstract. Increasing the combustion engine drive systems efficiency is currently being achieved by structural changes in internal combustion engines and its equipment, which are geared towards limiting mechanical, thermal and outlet losses. For this reason, downsizing. In addition to these changes, all manner of exhaust gas energy recovery systems are being investigated and implemented, including turbocompound, turbogenerators and thermoelectric generators. The article presents the author's idea of a thermoelectric generator system of automotive applications ATEG (Automotive Thermoelectric Generator) and the study of the recovery of exhaust gas energy stream. The ATEG consists of a heat exchanger, thermoelectric modules and a cooling system. In this solution, 24 commercial thermoelectric modules based on Bi 2 Te 3 (bismuth telluride) were used. Measurements were made at two engine test sites on which SI and CI engines were installed. The exhaust gas parameters (temperature and mass flow rate), fuel consumption and operating parameters of the ATEG -the intensity and the voltage generated by the thermoelectric modules and the temperature on the walls of the heat exchanger -were all measured in the experiments. Based on the obtained results, the exhaust gas energy flow and the power of the ATEG were determined as well as its effect on the diesel engine drive system efficiency.

We have analyzed the increase of the overall efficiency of a spark ignition engine through energy recovery following the application of an automotive thermoelectric generator (ATEG) of our own design. The design of the generator was developed following emission investigations during vehicle driving under city traffic conditions. The measurement points were defined by actual operation conditions (engine speed and load), subsequently reproduced on an engine dynamometer. Both the vehicle used in the on-road tests and the engine dynamometer were fit with the same, downsized spark ignition engine (with high effective power-to-displacement ratio). The thermodynamic parameters of the exhaust gases (temperature and exhaust gas mass flow) were measured on the engine testbed, along with the fuel consumption and electric current generated by the thermoelectric modules. On this basis, the power of the ATEG and its impact on overall engine efficiency were determined.
