Abstract
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
