摘要

在美国，住宅烘干衣物的能耗约占住宅部门总能耗的 5%。大多数烘干机使用电阻电加热器烘干衣物，效率较低。使用蒸汽压缩热泵的高效烘干机既昂贵又复杂，在美国的市场份额不大。本文介绍了一种新型滚筒式干衣机，它使用小型热电热泵，气流速度比一般干衣机快。文中介绍了热电热泵和高速鼓风机的台式性能，并描述了干衣机原型的开发过程。在一系列气流速率和热电热泵应用电流条件下，对干燥机的效率和干燥时间进行了测试。在这些测试中，综合效率系数为 5.09-6.29 磅BDW/千瓦时（特定水分提取率为 1.23-1.53 公斤瓦/千瓦时），干燥时间为 100-138 分钟。测得的效率比美国的最低效率标准高出 36 %-68 %，与基于蒸汽压缩热泵的干衣机相比，原型干衣机的成本更低、组件更简单，而且不使用制冷剂。该小型热电热泵干衣机的性能还与文献中描述的热电滚筒式干衣机的前几代产品进行了比较。

Fast-airflow tumble clothes dryer with small thermoelectric heat pump: Experimental evaluation

Residential clothes drying accounts for about 5 % of the total residential-sector energy consumption in the United States. Most dryers use electric resistance heaters to dry clothes and have low efficiencies. Higher-efficiency dryers that use vapor compression heat pumps are expensive and complex and have not gained a large market share in the United States. A novel tumble clothes dryer using a small thermoelectric heat pump with faster airflow than typical dryers is presented in this work. The benchtop performance of the thermoelectric heat pump and high-speed blower are presented, and the development of the prototype dryer is described. The dryer was tested for efficiency and dry time for a range of airflow rates and applied currents to the thermoelectric heat pump. The combined efficiency factor was 5.09–6.29 lb_BDW/kWh (specific moisture extraction rate of 1.23–1.53 kg_w/kWh) with 100–138 min dry times for these tests. The measured efficiency was 36 %–68 % greater than the minimum efficiency standard in the United States, and compared with vapor compression heat pump–based clothes dryers, the prototype dryer had less expensive, less complex components and did not use refrigerants. The performance of this small thermoelectric heat pump clothes dryer is also compared with previous iterations of the thermoelectric tumble clothes dryer described in the literature.

期刊介绍： Thermal Science and Engineering Progress (TSEP) publishes original, high-quality research articles that span activities ranging from fundamental scientific research and discussion of the more controversial thermodynamic theories, to developments in thermal engineering that are in many instances examples of the way scientists and engineers are addressing the challenges facing a growing population – smart cities and global warming – maximising thermodynamic efficiencies and minimising all heat losses. It is intended that these will be of current relevance and interest to industry, academia and other practitioners. It is evident that many specialised journals in thermal and, to some extent, in fluid disciplines tend to focus on topics that can be classified as fundamental in nature, or are ‘applied’ and near-market. Thermal Science and Engineering Progress will bridge the gap between these two areas, allowing authors to make an easy choice, should they or a journal editor feel that their papers are ‘out of scope’ when considering other journals. The range of topics covered by Thermal Science and Engineering Progress addresses the rapid rate of development being made in thermal transfer processes as they affect traditional fields, and important growth in the topical research areas of aerospace, thermal biological and medical systems, electronics and nano-technologies, renewable energy systems, food production (including agriculture), and the need to minimise man-made thermal impacts on climate change. Review articles on appropriate topics for TSEP are encouraged, although until TSEP is fully established, these will be limited in number. Before submitting such articles, please contact one of the Editors, or a member of the Editorial Advisory Board with an outline of your proposal and your expertise in the area of your review.
