the optimization design and parametric study of thermoelectric radiant cooling and Heating Panel
Applied Thermal Engineering, 2017Co-Authors: Limei Shen, Cheng Tao, Huanxin ChenAbstract:Abstract Thermoelectric radiant air-conditioning (TE-RAC) system is a promising approach to implement thermoelectric technology in large-scale refrigeration system applications in future. However, no standard exists for the in situ design and the performance evaluation of thermoelectric radiant Heating/cooling Panel. Thus, this study aims to not only clarify the design procedure but also to share our thermal physical model and design configurations of the thermoelectric radiant Panel to serve as a reference for other similar design cases. In addition, a simplified representation approach for the thermal characterization of thermoelectric Panels is also discussed. The main design variables are the number of thermoelectric modules and the size of radiant Panels. The inner surface transient temperature distribution of thermoelectric radiant Panels is discussed, and the approaches for improving the uniformity of the inner surface temperature are proposed. The influence of cooling/Heating load on the uniformity of the inner surface temperature is a slight larger than the size of the Panel, so the matching design is very important. The results show that the optimal thickness of thermoelectric radiant Panels is 4 mm, and the number of thermoelectric modules (TEM) is 16 per square meter, which also could solve the issues about dew formation and uniformity of inner surface temperature.

dynamic heat transfer modeling and parametric study of thermoelectric radiant cooling and Heating Panel system
Energy Conversion and Management, 2016Co-Authors: Ling Zhang, Yingzi Wang, Jing Wu, Xiliang WangAbstract:Abstract Radiant Panel system can optimize indoor thermal comfort with lower energy consumption. The thermoelectric radiant Panel (TERP) system is a new and effective prototype of radiant system using thermoelectric module (TEM) instead of conventional water pipes, as heat source. The TERP can realize more stable and easier system control as well as lower initial and operative cost. In this study, an improved system dynamic model was established by combining analytical system model and artificial neural networks (ANN) as well as the dynamic calculation functions of internal parameters of TEM. The double integral was used for the calculation of surface average temperature of TERP. The ANN model and system model were in good agreement with experiment data in both cooling and Heating mode. In order to optimize the system design structure, parametric study was conducted in terms of the thickness of aluminum Panel and insulation, as well as the arrangement of TEMs on the surface of radiant Panel. It was found through simulation results that the optimum thickness of aluminum Panel and insulation are respectively around 1–2 mm and 40–50 mm. In addition, TEMs should be uniformly installed on the surface of radiant Panel and each TEM should stand at the central position of a square-shaped typical region with length around 0.387–0.548 m.
