“…These benefits allow the thermoelectric generator (TEG) technology to be used to fully utilize many kinds of heat Bulletin of Electr Eng & Inf ISSN: 2302-9285  sources. However, because the heat source fluctuates, the hot side temperature of TEG is not always consistent, which will significantly reduce output performance [17]. So as the current increases, the cold side temperature decreases and cooling power increase [18].…”

Solar-powered thermoelectric air conditioning systems offer distinct advantages over traditional cooling methods, including thermal comfort, absence of moving parts, and eco-friendliness as they operate on solar energy. Despite these benefits, they exhibit a lower coefficient of performance (COP) compared to conventional systems. In this study, a solar-powered thermoelectric air conditioning system based on the Peltier effect was experimentally investigated in Baghdad during September (39 °C to 32 °C). The system was designed to cool a small 1 m³ test room. The six Peltier modules were divided into groups, each powered by a different electrical source with varying ON/OFF intervals. The highest COP achieved was 0.649, with an optimal outlet air temperature of 22-23 °C and a 20 minute switching cycle. Notably, the inlet air velocity directly influenced COP and outgoing air temperature. The study also indicated improved performance at reduced air flow, making Peltier air coolers ideal for hot regions.

“…Switchable thermal transport is key to the development of rectifiers, transistors, switches, and rheostats that operate based on heat transfer . Realization of these devices would enable a revolution in the thermal management of electronics, solid-state cooling, and energy conversion, − but such advances hinge on the development of materials wherein thermal conductivity can be controlled in a predictable way. A thermal conductivity switch is characterized by several parameters, including the degree to which the conductivity changes upon switching (switching ratio), how fast switching occurs (switching time), the external stimulus used to trigger the change, and cyclability.…”

The ability to control thermal transport is critical for the design of thermal rectifiers, logic gates, and transistors, although it remains a challenge to design materials that exhibit large changes in thermal conductivity with switching ratios suitable for practical applications. Here, we propose the use of flexible metal–organic frameworks, which can undergo significant structural changes in response to various stimuli, to achieve tunable switchable thermal conductivity. In particular, we use molecular dynamics simulations to show that the thermal conductivity of the flexible framework Fe(bdp) (bdp2– = 1,4-benzenedipyrazolate) becomes highly anisotropic upon transitioning from the expanded to the collapsed phase, with the conductivity decreasing by nearly an order of magnitude along the direction of compression. Our results add to a small but growing number of studies investigating metal–organic frameworks for thermal transport.

“…Thermoelectric cooling (TEC) is based on the Peltier effect, in which the phenomenon of heat transfer from a low temperature heat source to a high temperature one takes place. Peltier modules (called also TE modules) are characterized by such advantages as small dimensions, fast reaction, lack of moving parts [5] and potential media leakages [6]. Considering this characteristic, increasing attention has been paid to TECs in the recent years [7].…”

Over the past decades, clean and renewable energy has become a subject of great interest to both science and industry in response to the pollution caused by conventional energy sources. Its useful form should always meet the requirements of high performance and low environmental impact, while remaining within the scope of the expected functionality. The purpose of study presented in this paper was to determine the operational characteristics for a recently developed photovoltaic (PV)-powered thermoelectric (TE) cooling system with heat recovery. The characteristics of operation of the tested system were determined within the use of a specially developed measurement system. The conducted experimental research allowed describing the conditions of power supply for TE module using PV system, calculate the coefficient of performance (COP) for the whole TE cooling system with heat recovery and calculate the environmental impact indicators based on the material and energy balance used for life cycle assessment (LCA).
