“…Results showed that the system produced 1250 W for heating and 375 W for cooling with respective COPs in range of 1.5 to 4.0 and 0.5 to 2.5 depending on airflows, temperature gradient, and voltage supply. Han et al 45 conducted an experimental study for split liquid circulation assisted TEM cooling system and found that the system achieved maximum cooling power of 2028 W and maximum COP of 4.4 for a 10°C temperature differential. Cai et al 46 analyzed the performance active thermoelectric ventilated system and compared it with traditional cooling systems, and concluded that the ATEV system is a promising candidate for building integrative cooling.…”

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.

“…As Figure 6 shown, the heat exchange method of the hot side of the thermoelectric cooling device adopts water-cooled circulation heat exchange, and the cold side adopts forced convection heat exchange. In order to ensure good heat transfer efficiency, use a clamping device to dissipate the finned heat sink, the thermoelectric cooling modules and the water tank are clamped (Han and Wang, 2021). The water tank flows the heat into the radiator through the water pipe to dissipate the heat and sends the heat to the hot zone; the cold side is radiated by the fan on the surface of the finned heat sink, and the cold air is sent into the cold zone.…”

In cold chain logistics, refrigerated trucks are used for long-distance transportation across cities, and insulated trucks are used for short-distance delivery within cities. However, the small insulated vans for short-distance transportation like delivering home in urban have heat leakage and no pre-cooling, the transportation time of traffic congestion becomes longer, resulting in poor insulation effect. So, to achieve stable temperature control is difficult, it leads to a big fluctuation in the temperature of the cargo. The thermoelectric cooling technology has the unique advantages of compact structure, flexible layout, no refrigerant, and environmental friendliness, which is very suitable for controlling the temperature of the small insulated vans. In the paper, relationship among COP, working power, and working current of the designed thermoelectric cooler (TEC) is investigated first. And then the best working state of the TEC is obtained. Next, set hot and cold dual temperature zones to ensure the effective use of energy based on thermoelectric cooling characteristics, arranged the cooling device in the insulated van, and revealed the changes in the temperature of the compartment and the cargo through the actual vehicle test. Compared the thermal insulation effect of the compartment with or without thermoelectric cooling technology through CFD. According to the simulation results, the cargo temperature of the insulated van fluctuates between 4 and 6°C within 2.5 h of actual delivery in urban, the insulated van using thermoelectric cooling technology can make the temperature of the cargo fluctuate within 1.5°C. The above proved the good insulated effect of the thermoelectric cooling insulated vans. Finally, the influence of the working time of the thermoelectric refrigeration system on the temperature control effect is also studied. The research results have a certain guiding significance for the application of thermoelectric cooling technology in insulated vans.

Thermoelectric heat pump is a feasible solution for developing refrigerant-free technology, but most studies tend to focus more on cooling capacity. In this paper, a finite element model of the water-source thermoelectric heat pump module is established. By comparing the changes of the coefficient of performance (COPh) of the thermoelectric heat pump module under different pipe diameters(d), currents(I), temperatures(T), and temperature differences(∆T), the main parameters affecting the performance of the thermoelectric heat pump module are explored. Results show that: within the range of 20°C to 45°C, the influence of water temperature on COPh is relatively small under the same temperature difference; the heat output is not affected by the ∆T when I=7.17A, and the ∆T shows different trends in the left and right intervals: under the condition of large ∆T between the hot and cold ends of the module, there is an optimal working current, which increases with the increase of ∆T.Research has shown that I and ∆T are the main parameters affecting module performance. Under extreme operating conditions, using a specific value of current can simultaneously increase heating power and heating performance coefficient.
