摘要
换热器是小型制冷装置(冰箱、冷柜、空调、热泵等)的重要组成部件,从性能计算模型与方法、结霜与积灰特性及高效节能技术三个方面阐述了其技术研究进展和发展现状。分析表明,在高效节能技术方面,小管径、微通道以及抑霜与除霜等技术是主流方向。希望所综述内容能给行业技术人员提供一定参考。
Heat exchanger is an important component of small refrigerators(Refrigerator,freezer,air conditioning,heat pump,etc.).This paper summarize current technology and research situation of heat exchanger for small refrigerators from following three aspects:the calculation model and method for heat exchanger performance,frosting and fouling characteristics and high efficiency and energy saving technology of heat exchangers.For the high efficiency and energy saving technology of heat exchangers,the fin-and-tube heat exchangers using small diameter tubes,micro-channel heat exchangers and anti-frosting and defrosting technology have always been the mainstream.The review provide references for the technical personnel in refrigeration and air conditioning industry.
