Sažetak
In the paper, numerical and experimental analyses of heat and mass transfer during frost formation on a fin-and-tube heat exchanger have been performed. The modelling of frost formation on cold surfaces placed in a humid air stream requires a complex mathematical approach. Results have shown that frost layer growth is faster with higher inlet air humidity. Frost layer formation significantly influences the heat transfer between air and refrigerant. Using the developed mathematical model, the algorithm and the computer code, which have been experimentally validated, it is possible to predict a decrease of exchanged heat flux in the heat exchanger under frost growth conditions.
