The choice of void fraction model is found to have a major effect on refrigerant inventory prediction. The maximum variation of predictions ranges from a factor of 10 for low-ambient, heating-mode evaporators to 4.2 for cooling-mode evaporators and 1.7 for high-ambient cooling-mode condensers assuming no subcooling.
