“…While studying the optimum design of TE devices, dimensionless groups are used to properly define and represent important parameters of the TE device [40]. According to this study, the optimum design comprises the optimum parameters such as efficiency, current, power, geometry or number of thermocouples, and thermal resistances of heat sinks.…”

Abstract:Thermoelectric (TE) technology is regarded as alternative and environmentally friendly technology for harvesting and recovering heat which is directly converted into electrical energy using thermoelectric generators (TEG). Conversely, Peltier coolers and heaters are utilized to convert electrical energy into heat energy for cooling and heating purposes The main challenge lying behind the TE technology is the low efficiency of these devices mainly due to low figure of merit (ZT) of the materials used in making them as well as improper setting of the TE systems. The objective of this work is to carry out a comprehensive review of TE technology encompassing the materials, applications, modelling techniques and performance improvement. The paper has covered a wide range of topics related to TE technology subject area including the output power conditioning techniques. The review reveals some important critical aspects regarding TE device application and performance improvement. It is observed that the intensified research into TE technology has led to an outstanding increase in ZT, rendering the use TE devices in diversified application a reality. Not only does the TE material research and TE device geometrical adjustment contributed to TE device performance improvement, but also the use of advanced TE mathematical models which have facilitated appropriate segmentation TE modules using different materials and design of integrated TE devices. TE devices are observed to have booming applications in cooling, heating, electric power generation as well as hybrid applications. With the generation of electric energy using TEG, not only does the waste heat provide heat source but also other energy sources like solar, geothermal, biomass, infra-red radiation have gained increased utilization in TE based systems.However, the main challenge remains in striking the balance between the conflicting parameters; ZT and power factor, when designing and optimizing advanced TE materials.Hence more research is necessary to overcome this and other challenge so that the performance TE device can be improved further.

In the present work, the optimum design of thermoelectric car seat climate control (CSCC) is studied analytically in an attempt to achieve high system efficiency. Optimal design of a thermoelectric device (element length, crosssection area and number of thermocouples) is carried out using our newly developed optimization method based on the ideal thermoelectric equations and dimensional analysis to improve the performance of the thermoelectric device in terms of the heating/cooling power and the coefficient of performance (COP). Then, a new innovative system design is introduced which also includes the optimum input current for the initial (transient) startup warming and cooling before the car heating ventilation and air conditioner (HVAC) is active in the cabin. The air-to-air heat exchanger's configuration was taken into account to investigate the optimal design of the CSCC.

“…Это условие приводит к несовпадению режима макси-мальной холодопроизводительности материала и режима максимальной холодопроизводительности т/э устройства Q max вследствие возникновения перепадов температур на конструкционных элементах устройства между мате-риалом и тепловыми средами. Моделирование парамет-ров т/э охлаждающих устройств с учетом этих тепловых сопротивлений широко освещено в литературе [1][2][3][4][5][6][7][8][9]. Нахождение оптимальных параметров устройств для реализации режима Q max предлагается выполнять чис-ленными методами с помощью компьютерных программ или эмпирически с некоторыми допущениями, тaк как с учетом тепловых сопротивлений зависимости выходных параметров устройств становятся громоздкими.…”

При моделировании термоэлектрических охлаждающих устройств необходимо учитывать тепловые сопротивления конструкционных элементов, расположенных между материалом и теплоотдающей средой (на холодной стороне) и между материалом и теплопринимающей средой (на горячей стороне устройства). В работе предложена безразмерная математическая модель, описывающая холодо- и теплопроизводительность, напряжение питания и холодильный коэффициент устройств в зависимости от тока с учетом указанных тепловых сопротивлений. С помощью данной модели могут быть найдены оптимальные значения тока и тепловых сопротивлений на горячей и холодной стороне устройства для реализации максимальной холодопроизводительности и других режимов работы.
