“…Normally, there are two approaches to enhance the ZT value. One is the optimization of power factor by band engineering or tuning the carrier concentration and the other is depressing the κ L by point defect scattering, alloy scattering, nanostructuring et al [4][5][6].…”

Abstract:The Ni-doped ZrCo 1−x Ni x Sb half-Heusler compounds were prepared by arc-melting and spark plasma sintering technology. X-ray diffraction analysis results showed that all samples were crystallized in a half-Heusler phase. Thermoelectric properties of ZrCo 1−x Ni x Sb compounds were measured from room temperature to 850 K. The electrical conductivity and the absolute value of Seebeck coefficient increased with the Ni-doping content increasing due to the Ni substitution at Co. sites. The lattice thermal conductivity of ZrCo 1−x Ni x Sb samples was depressed dramatically because of the acoustic phonon scattering and point defect scattering. The figure of merit of ZrCo 1−x Ni x Sb compounds was improved due to the decreased thermal conductivity and improved power factor. The maximum ZT value of 0.24 was achieved for ZrCo 0.92 Ni 0.08 Sb sample at 850 K.

The patented thermoelectric intensifier of heat transfer between two moving media with different temperatures was investigated. In its design, to increase the intensity of heat exchange between media, the use of fan units is provided. A mathematical model of the device was developed, based on the solution of the heat balance equation for media flows in transport zones for forward flow conditions. The calculated data are presented in the form of the dependence of the temperature change of moving media along the length of the intensifier for different values of the heat transfer coefficient between the junctions of the thermoelectric battery and the air medium in the gap of the device. It has been established that the larger the temperature difference between the inlet media, the more abrupt the dependence of the limiting length of the thermoelectric battery on the heat transfer coefficient will be.

“…Due to these merits, TEC devices have been widely used to provide cooling in several situations, such as water machines, car refrigerators, chip cooling, air conditioners of outdoor telecommunication cabinets, dehumidifiers, and water generators. Many researches focused on improving the performance of TEC devices include Liu et al [11] who invested the coefficient of performance (COP) of the thermoelectric module, Muhammad et al [12] who reviewed the materials, modeling approaches, and strategies to improve the cooling performance and practical application of TECs, Integrating TECs into harvested atmospheric water vapor makes full use of the merits of TECs and the size of a water generator can be reduced at the same time. TEC devices cool the water vapor temperature to the air dew point and makes it condense into droplets on the cold-side surface.…”

Found in some specific scenarios, drinking water is hard for people to get, such as during expeditions and scientific investigations. First, a novel water generator with only two thermoelectric coolers (Model A) is designed for extracting water from atmospheric vapor and then experimentally studied under a small inlet air flow rate. The impact of operating conditions on surface temperatures of cold/hot sides and water yield are investigated, including the air flow rate and humidity. Alternately, to determine the super performance of Model A, a comparative experiment between Model A and a reference model (Model B) is carried out. The results suggest that both the cold/hot temperature and water yield in Model A increases with the humidity and air flow rate rising. Seen in comparisons of Model A and Model B, it is found that, at an air humidity of 90% and air flow rate of 30 m3/h, the total water yield was increased by 43.4% and the corresponding value reached the maximum increment of 66.7% at an air humidity of 60% and air flow rate of 30 m3/h. These features demonstrate the advantage of Model A especially in low air humidity compared to Model B.
