“…For example, in an automotive study, 72 TEG modules were applied to a heat pipe as a means to replace the radiator. This resulted in producing 28W at idle and 75W at 80 km/hr [6]. Thermoelectric generator modules in an array can be arranged in parallel, in series, or in combination to produce the most efficient amount of power for their application.…”

Many military systems produce thermal energy as a by-product. Generally, this so-called waste heat is lost to the surroundings. Capturing the waste heat and putting it to beneficial use could increase the efficiency of military systems, while having the added benefit of reducing thermal signatures. This paper outlines the application of modeling and simulation to estimate the usable electric power produced by a thermoelectric generator (TEG) array on the exhaust muffler of a small fossil fuel generator. The simulation results informed design, construction, and testing of an initial prototype. Key prototype test variables were temperature difference, load resistance, and electric current. The results of the experiment were compared to and used to update the initial model. This small-scale effort provides initial insight into the efficacy of applying thermoelectric generators to military systems. Future work will explore larger arrays, as well as detailed investigation of the tradespace to identify promising equipment or applications, and inform capability and acquisitions requirements.

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].

“…Cooling systems using thermoelectric elements include refrigerators using thermoelectric elements [11][12][13][14][15][16][17][18], electronic equipment coolers [19][20][21][22][23][24][25][26][27], dehumidifiers [28,29], and air conditioners [30]. In air conditioners in particular the performance of a hybrid system which combines the thermoelectric elements is 10% higher than conventional systems.…”

This paper proposes a control method to improve the energy efficiency and performance of cooling fans used for cooling. In Industry 4.0, a large number of digital data are used, and a large number of data centers are created to handle these data. These data centers consist of information technology (IT) equipment, power systems, and cooling systems. The cooling system is essential to prevent failure and malfunction of the IT equipment, which consumes a considerable amount of energy. This paper proposes a method to reduce the energy used in such cooling systems and to improve the temperature control performance. This paper proposes an fuzzy proportional integral(FPI) controller that controls the input value of the proportional integral(PI) controller by the fuzzy controller according to the operation state, a VFPI (Variable Fuzzy Proportional Integral) controller that adjusts the gain value of the fuzzy controller, and a variable fuzzy proportion integration-variable limit (VFPI-VL) controller that adjusts the limit value of the fuzzy controller’s output value. These controllers control the fan applied to the cooling system and compare the energy consumed and temperature control performance. When the PI controller consumes 100% of the power consumed, the FPI is 50.5%, the VFPI controller is 44.3%, and the VFPI-VL is 32.6%. The power consumption is greatly reduced. In addition, the VFPI-VL controller is the lowest in temperature variation, which improves the energy efficiency and performance of the cooling system using a fan. The methods presented in this paper can not only be applied to fans for cooling, but also to variable speed systems for various purposes and improvement of performance and efficiency can be expected.
