“…Huang and Duang [8,9] presented a theoretical model, utilized the numerical solutions of the model to control the temperature difference of the TEC device, and introduced the influences of thermal resistance into their model for calculating the efficiency of TEC. Recently, a dimensionless mathematical model is constructed by Naji et al [10] to investigate the influences of the dimensionless parameters on the performance of TEC. Authors also found that the cold end temperature was elevated as the electrical resistivity is decreased and was reduced as the Thomson coefficient is increased.…”

The contribution presents a flexible simulation model of thermoelectric devices, suitable for the design and control verification of related energy systems, e.g. waste heat recovery by a Thermoelectric Generator. The models are built according to the object-oriented scheme of the Modelica ® language. Based on the essential physical effects of thermoelectric materials, the model components are applicable to describe a Thermoelectric Generator as well as a Peltier Cooler. Unlike averagedproperties, steady-state models seen in related works, the presented models can respect the temperature dependencies of decisive material properties in 1D spatial temperature resolution and are capable of describing transient thermal behavior.

“…In general, the conventional non-equilibrium thermodynamics (Angrist 1992, Bejan 1997) is used to analyse the performance of single-stage one-or multiple-element thermoelectric generators (Sisman and Yavuz 1995, Chen et al 1997, Omer and Infield 1998, Rowe and Min 1998, Huang et al 2000, Mayergoyz and Andrel 2001, Naji et al 2003, Nuwayhid et al 2005, Yu and Zhao 2007 and refrigerators (Huang et al 2000, Chua et al 2002, Gordon et al 2002, Dai et al 2003, Cheng and Lin 2005, Yang et al 2005, Chakraborty et al 2006, Wang et al, 2006, Abramzon 2007, Chakraborty et al, 2007, Lee and Kim 2007, Pan et al 2007). All objects of these researches are independent thermoelectric devices, that is, they generate direct-current power source for users (thermoelectric generator) or need a direct-current power source to provide direct current (thermoelectric refrigerator).…”

Based on the finite time thermodynamic model of thermoelectric generator-driven thermoelectric refrigerator with losses of external heat transfer, Joulean heat inside the thermoelectric device and the heat leakage through the thermoelectric couple leg, this paper analysed the effects of generator heat source temperature and refrigerator cooling temperature on the performance of the combined system using the combination of finite time thermodynamics and non-equilibrium thermodynamics. For a fixed total heat transfer surface area of four heat exchangers, the allocations of the heat transfer surface area among the four heat exchangers are optimised for maximising cooling load and the coefficient of performance (COP) at different source temperature of the combined thermoelectric refrigerator device, respectively. For a fixed total number of thermoelectric elements, the ratio of number of thermoelectric elements, i.e. the number of thermoelectric elements of the generator to that of the whole device is also optimised for maximising cooling load and the COP at different source temperature of the combined device, respectively. The change features of four design variables, i.e. the ratio of number of thermoelectric elements, the total heat transfer surface area ratio, the generator heat transfer surface area ratio and the refrigerator heat transfer surface area ratio are obtained, respectively. Moreover, optimum working electrical currents for maximum cooling load and COP at different total number of thermoelectric elements and different total heat transfer area are obtained, respectively.
