- Abstract
The paper presents the results of a study of frost formation on the surface of the heat exchanger fins when a moist air flow is flown around. The description of the experimental stand and the experimental procedure are given. The effect of frost formation on the efficiency of heat transfer was estimated from the time temperature dependences at various points of the fin surface. During the experiments, the thickness of the frost layer and the degree of overlap of the intercostal spaces were monitored visually and using an anemometer. Analysis of the experimental data revealed the features of frost formation depending on the geometric parameters of the ribs. The results obtained can be used in the development and design of heat exchangers for refrigeration equipment
