“…Zhou et al 54 analyzed the performance enhancement of evaporative cooling system by use of TEM and concluded that the system can have high COP and is able to maintain primary air temperature to low values even comparable to dew point temperature (ie, cold temperature when air reaches 100% RH or maximum saturation). Wang et al 55 analyzed the efficiency improvement of air‐cooled natural circulation systems using TEM and concluded that the cooling capacity of such systems can be enhanced by upto 37% by using suggested designs. Wang et al 56 analyzed TEM application in space heating and observed an average system COP of 1.8.…”

Thermoelectric module (TEM) is a scalable, reliable, and noise-free solid-state device that converts thermal energy into electrical energy and vice-versa. TEM has been explored for cogeneration, electronics cooling, power production, waste heat harnessing, and air-conditioning. The potential applications of TEM-based systems are in the building, for heating, ventilation, and airconditioning (HVAC), which represents its significant share in the energy consumption in the building sector. A photovoltaic powered thermoelectric system has even a stronger techno-economical potential. The main objective of the study is to explore the potential of PV-powered thermoelectric technology as a distributed air-conditioning system in buildings. In this study, a comprehensive review on PV-powered thermoelectric technology is presented in addition to several new design concepts for application in future development of sustainable zero energy building technologies in view of sustainability and global climate change concerns. A novel "STEM-Wall" concept is also discussed concerning future thermoelectric system designs for buildings. Additionally, the thermal comfort aspect of HVAC systems is critically analyzed by reviewing the standard predicted mean vote and predicted percentage of dissatisfied indices. The research outcome, analysis, and potential of TEM applications for future sustainability and thermal comfort in buildings are presented. Further follow-up research areas are also identified.
