“…The Peltier coefficient is associated with a heating effect when the power supply polarity is switched and a cooling effect as the electric current moves from the N-type to the P-type semiconductor. The direction of the electric current thus determines the temperatures at both the hot and cold ends [7]. Recent advancements in thermoelectric materials suggest significant potential for enhancing their thermoelectric efficiency, marking a substantial stride towards novel application areas for thermoelectric modules [8].…”

The compact sizing and lightweight characteristics of thermoelectric devices have garnered significant attention, leading to their widespread use across varied fields. This study experimentally investigates the application of thermoelectric refrigeration in air conditioning, employing a moderately designed system. A unique, multi-U shaped heat sink system was developed, wherein thermoelectric devices were affixed onto rectangular tubes befitting their dimensions, thereby facilitating water as an auxiliary medium for energy transfer. This design enabled the transformation of cold water from the system's cold side to the indoor unit's water-air heat exchanger, while hot water was directed to the outdoor evaporative cooling tank. A Peltier-type thermoelectric device was harnessed for this experiment. The devised setup was subjected to multiple tests to evaluate its thermal performance under the climate conditions of Najaf. Preliminary results validated the effectiveness of the water cooling methodology, with the water temperature observed to decrease to 14℃. Consequently, the room air was cooled by the water-air heat exchanger, reaching temperatures between 20℃ and 24℃. This study underscores the potential of integrating thermoelectric devices with innovative heat sink designs for efficient room air cooling.

“…In [4] it is mentioned that the maximum cooling capacity improves for an increment in the cross sectional area of the thermo-element or a decrement in the length. The maximum achievable coefficient of performance, irrelevant of the maximum cooling capacity, remains constant for any change in the area or the length of the thermo-element.…”

Present paper gives a picture of a conceptual design of an air conditioner using Peltier modules to achieve desired amount of cooling. The appearance of this thermoelectric type of air conditioner resembles a conventional window air conditioner. This brings the simplicity in construction. The air conditioner is intended to take up the cooling load in volume of space as in conventional automobiles such as cars. If conventional vapour compression type of air conditioner currently used in vehicles is replaced with this one with an arrangement for its placement, it would reduce the total weight of vehicle and increase fuel economy.

Thermoelectric cooling (TEC) is critically important in thermal management of laser modules or chips and potentially for personalized thermoregulation. The formulae for efficiency in standard textbooks can only describe the performance of a TEC module with ideal thermal conditions, that is, fixed terminal temperatures, but are unable to deal with a real TEC system where heat transfer at its interfaces with the heat source and sink are finite and with thermal resistances. Here, we define the TEC system‐level performance indices, that is, the maximum cooling power, temperature difference, and coefficient of performance, by introducing a set of explicit formulae. The external heat transfer conditions are taken into account as dimensionless thermal resistance parameters. With these formulae, the TEC system performances are evaluated elegantly with errors well within ±5% over broad operating conditions. We further optimize the cooling power and the coefficient of performance in practical scenarios and establish a general White–Box design procedure for TEC systems, which enables a transparent design process and straightforward analysis of performance bottlenecks. A set of cooling experiments are performed to validate the analytical model and to illustrate the dependence of system design on realistic thermal conditions. By choosing the suitable TEC module parameter under given external heat transfer conditions, the cooling power can be improved by more than 100%. This work sheds some light on the integral design of TEC systems for broad applications to take full advantage of the advanced thermoelectric materials in the cooling field.image
