“…Benziger and Anu Nair [28] conclude that the lower power input can be obtained at higher COP so the rate of energy consumption can be reduced. Tipsaenporm et al [29] reported that the thermoelectric cooling capacity will proportionally increase depending on the current electrical input and ratio of thermoelectric element.…”

Thermoelectric cooling (TEC) is a new attractive method that is can be used as a temperature controller. Thermoelectric module (TEM) is a device that environmentally friendly utilizing for cooling and heating application such as heat pump and power generation. Therefore, the understanding of relation between electrical conductivity and heat conductivity of the TEC material is essentially to improve the coefficient of performance (COP) efficiency. The figure of merit is addressed by focusing the best material in TEC with different cooling material. The critical finding of TEC for this review paper is the higher the electrical conductivity and the lower thermal conductivity, the maximum the COP. Finally, the possiblity of the TEC application is reviewed according to the advantages of TEC such as high reliability, less maintenance and compact size that commercially found in large range of thermoelectric cooling system.

In this chapter, design and analysis study of thermoelectric cooling systems are described. Thermoelectric (TE) cooling technology has many advantages over the conventional vapor-compression cooling systems. These include: they are more compacted devices with less maintenance necessities, have lower levels of vibration and noise, and have a more precise control over the temperature. These advantages have encouraged the development of new applications in the market. It is likely to use TE modules for cooling the indoor air and hence compete with conventional airconditioning systems. These systems can include both cooling and heating of the conditioned space. In order to improve the performance of the TE cooling systems, the hot side of the TE should be directly connected to efficient heat exchangers for dissipation of the excessive heat. Finally, TE cooling systems can be supplied directly by photovoltaic to produce the required power to run these cooling systems.

“…With today’s best commercial thermoelectric modules (Bi 2 Te 3 -based material with

around 1 at 300 K), the peak COP of a thermoelectric module can reach as high as 8 under a temperature gradient of 5 K ( Rowe, 1995 ). For this purpose, various heat exchanging schemes, including water-cooling systems ( Cheng et al., 2011 ; Lim and Jeong, 2018 ), phase change material systems ( Zhao and Tan, 2014 ), and evaporative cooling systems ( Tipsaenporm et al., 2012 ) have been proposed for TEACs, and their COPs indeed improved by 20% to 40%, despite being still lower in the range of 0.34 to 2.59 ( Baheta et al., 2019 ). Together with these advanced heat-exchanging systems, thermoelectric air conditioning systems have been leveled up to building applications, with several styles like thermoelectric radiant panel ceiling ( Shen et al., 2013 ), air ducts ( Irshad et al., 2017 ), cooling facades ( Prieto et al., 2017 ), etc.…”
