Frost Formation Phenomenon in a Fin-and-Tube Heat Exchanger

A transient two-dimensional mathematical model of frost formation on a fin-and-tube heat exchanger has been developed and numerically solved. The mathematical model and numerical procedure have been experimentally validated. The results have shown that frost layer formation significantly influences heat transfer between air and a refrigerant. Frost layer growth is faster with higher inlet air humidity. Using the developed mathematical model, the algorithm and the computer code, which have been experimentally validated, it is possible to predict frost layer growth on fin-and-tube heat exchangers under different operating conditions.
