制冷空调用冷凝强化传热技术研究进展

Development of Study on Enhancement Techniques of Condensation Heat Transfer

管内冷凝与管外冷凝的风冷与水冷冷凝器是制冷空调系统中的重要部件。文中介绍了近期国内外冷凝强化传热技术的研究进展,包括管内冷凝与管外冷凝强化换热。简述了典型的冷凝强化传热元件的开发与应用,并对其强化传热性能进行了比较。

Air cooled and water cooled condensers are main parts for air conditioning, refrigeration and heat pumps. Recently development of study on enhancement techniques of condensation heat transfer at home and abroad was introduced in the paper, including condensation heat transfer inside and outside of tubes. The exploitation and application of typical enhancement techniques of condensation heat transfer was described, and its heat transfer performance was compared.
