“…Authors also found that the cooling efficiency of the thermoelectric cooler can be improved not only by increasing the figure of merit (ZT) but also by taking advantage of the Thomson effect. Khire et al [13] combined the thermoelectric devices with the solar energy units to design an active building envelope (ABE) system and mentioned that the thermal resistance of the heat sink is essential to determine the number of TEC units required. Chakraborty et al [14] presented a thermodynamic modeling of a solid state thermoelectric cooling device based on the temperature-entropy analysis.…”

“…The THP does not have moving parts, such as the refrigerant and compressor used in the conventional heat pump. Some studies have been conducted to adapt the THP to a building air conditioning system [19][20][21][22][23][24][25].…”

“…They suggested that two-stage THP systems have to be used over a large temperature range of the heated space and heat sink. Khire et al [23] proposed a multi-objective optimization-based design strategy for the thermoelectric unit of active building envelope systems. Kim et al [24] proposed an optimal design of an air-to-air THP for building ventilation and found that the coefficient of performance (COP) of the proposed system was enhanced by 4%.…”

Abstract:The main objective of this study was to develop a thermoelectric heat pump and liquid desiccant system based on a dedicated outdoor air system (THPLD-DOAS). An internally-cooled and -heated liquid desiccant system was used and a thermoelectric heat pump (THP) served as the desiccant cooling and heating energy source for dehumidification and regeneration of the desiccant solution, respectively. In order to investigate the energy-saving potential of the proposed system, its thermal performance and operating energy consumption during the cooling season were compared to those of a conventional dedicated outdoor air system with a ceiling radiant cooling panel system (DOAS-CRCP). Detailed simulations for each system were conducted under hot and humid climatic conditions. Their thermal performance under various room sensible heat factor (RSHF) conditions was evaluated to observe the energy performance, depending on the dehumidification performance, of the liquid desiccant system integrated with the THP. The results showed that the coefficient of performance (COP) of the THP ranged from 0.8 to 1.2 to maintain a sufficient dehumidification rate. The operating energy of the THPLD of the proposed system was 6.6% to 16.0% less than that of the chiller operating energy of a conventional DOAS. Consequently, the proposed system consumed 0.6-23.5% less operating energy compared to the conventional DOAS.

This paper evaluates the cooling performance and thermal comfort of a compact thermoelectric (TE) air conditioner. The compact TE air conditioner is composed of three TE modules. The cold and hot sides of the TE modules were fixed to rectangular fin heat sinks and fans. Thermal acceptability assessment was performed to find out whether the cooled air met the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) Standard-55's 80% acceptability criteria. A suitable condition occurred at 1 A current flow with a corresponding cooling capacity of 29.2 W, giving an average cooled air temperature of 28°C and 0.9 m/s cooled air velocity. The coefficient of performance was calculated and found to be $0.34. Economic analysis indicates that the payback period is 0.75 years when one compact TE air conditioner unit is used instead of a 1-ton conventional air conditioner.
