着霜を伴う熱交換器の着霜特性の調査

抄録

This paper reports the visualization of frost formation behavior at fins used in heat exchangers and the investigation of thermal properties of the frost layer surface using infrared thermography. Visualization uses two types of fins to understand the difference in frost formation behavior. In infrared thermography, the Nusselt number on the surface of the frost layer on a flat plate was calculated as a preliminary step to determine the heat transfer coefficient of the frost surface adhering to the fins.
