Abstract

A performance analysis model has been developed for fin-tube type heat exchanger for $CO_2$ heat pump. The model uses the tube-by-tube method Because air-side thermal resistance has a great portion among total thermal resistances, it is important to understand air-side heat transfer characteristics. The air-side heat transfer correlation has been proposed from experiments using water. The developed model was confirmed by experimental results and can be used for the performance analysis of heat exchanger.
