TLDR
A critical review of thermoelectric technology and assesses its potential applications in air conditioning and refrigeration is provided in this paper, with an emphasis on those related to air conditioning.Abstract:
A combination of factors—notably environmental concerns about global warming and ozone depletion due to refrigerants and the increasing demand for electronics and optoelectronic cooling—led to renewed activity in alternative cooling technologies. Currently, thermoelectric cooling is considered a popular cooling technology. This paper provides a critical review of thermoelectric technology and assesses its potential applications in air conditioning and refrigeration. The first part of this paper is devoted to the basic concept of thermoelectrics, with an overview of current thermoelectric materials and devices. The second part is a general overview of the applications of thermoelectric technology, with an emphasis on those related to air conditioning and refrigeration.read more

High-Thermoelectric Performance of Nanostructured Bismuth Antimony Telluride Bulk Alloys
Bed Poudel,Qing Hao,Yi Ma,Yucheng Lan,Austin J. Minnich,Bo Yu,Xiao Yan,Dezhi Wang,Andrew Muto,Daryoosh Vashaee,Xiaoyuan Chen,Jun-Ming Liu,Mildred S. Dresselhaus,Gang Chen,Zhifeng Ren +14 more
TL;DR: Electrical transport measurements, coupled with microstructure studies and modeling, show that the ZT improvement is the result of low thermal conductivity caused by the increased phonon scattering by grain boundaries and defects, which makes these materials useful for cooling and power generation.
