Title: Advances in Research and Application of Testing Technologies for Frost Parameters During the Frost Formation Process
Abstract: In this paper,the test rigs and experiment systems for frosting and defrosting processes in China and abroad were firstly investigated.Secondly,from the aspects of technology principles,application status and adaptable conditions,testing technologies for frost layer parameters,such as surface temperature,thickness,density,thermal conductivity and morphology of the frost layer,etc.were analyzed and studied.The results indicated that the frost thickness and frost surface temperature were the key parameters.In addition,the current used technologies were divorced from practice and resulted in the false defrosting under real operation conditions.Therefore,the photo-coupler technology for monitoring frost layer parameters was put forward to solve the corresponding problems,also to improve the control level of frost experiment systems and to improve the theory study of frost process.
