Abstract

Frost formation on an evaporator causes a significant problem increasing thermal resistance, resulting in a decrease in system performance. It is important for an improvement in system performance under low-temperature to?predict the frost formation. We measured the weight and height of frost layer on a cold surface in different inlet air conditions, cold surface temperatures, inlet air velocities. We derived the frost density and demonstrated the dominant factors of the frost density.
