Abstract

To solve the problem of thermal discomfort caused by the lack of cooling facilities on the Ferris wheel and to investigate the effect of the coupling effect of thermoelectric modules on the thermoelectric cooling (TEC) system, this paper proposes a two-module thermoelectric cooling and air-conditioning system that can be applied to the Ferris wheel. Firstly, the experimental platform was established to test the performance parameters of the TEC system and reveal the influence of the thermoelectric module (TEM) coupling effect on the system performance. Then, the thermal environment inside the Ferris wheel was simulated using the CFD method and human thermal comfort was evaluated. The results show that when the voltage of TEM1 and TEM2 is 10 V and 6 V respectively, the thermoelectric cooling and air-conditioning system has the best working performance, and the coefficient of performance (COP) is 0.43. And the human thermal comfort deviation A_EQT is 0.29, which is in a comfortable state under the action of the air-conditioning system.

基于热电冷却的摩天轮轿厢空调系统研究与热舒适性分析

为解决摩天轮因缺乏制冷设施而产生的热不适问题，并研究热电模块耦合效应对热电制冷（TEC）系统的影响，本文提出了一种可应用于摩天轮的双模块热电制冷空调系统。首先，建立了实验平台来测试 TEC 系统的性能参数，并揭示了热电模块（TEM）耦合效应对系统性能的影响。然后，利用 CFD 方法模拟了摩天轮内部的热环境，并对人体热舒适度进行了评估。结果表明，当 TEM1 和 TEM2 的电压分别为 10 V 和 6 V 时，热电半导体制冷空调系统的工作性能最佳，性能系数（COP）为 0.43。人体热舒适度偏差 AEQT 为 0.29，在空调系统的作用下处于舒适状态。

期刊介绍： The International Journal of Refrigeration is published for the International Institute of Refrigeration (IIR) by Elsevier. It is essential reading for all those wishing to keep abreast of research and industrial news in refrigeration, air conditioning and associated fields. This is particularly important in these times of rapid introduction of alternative refrigerants and the emergence of new technology. The journal has published special issues on alternative refrigerants and novel topics in the field of boiling, condensation, heat pumps, food refrigeration, carbon dioxide, ammonia, hydrocarbons, magnetic refrigeration at room temperature, sorptive cooling, phase change materials and slurries, ejector technology, compressors, and solar cooling. As well as original research papers the International Journal of Refrigeration also includes review articles, papers presented at IIR conferences, short reports and letters describing preliminary results and experimental details, and letters to the Editor on recent areas of discussion and controversy. Other features include forthcoming events, conference reports and book reviews. Papers are published in either English or French with the IIR news section in both languages.
