19-07: High Efficiency Heat Exchanger for Ice Energy Storage and BeyondFreezing ice on coils is a slow and transient process that hinders the deployment of ice thermal energy storage systems for large commercial buildings. Here, we share observations of a novel interfacial phenomenon that was used to engineer an ice phobic heat exchanger. Water drops that were frozen on the ice phobic surface demonstrated extremely low interfacial adhesion, allowing the frozen drops to be shed off by body forces alone. Heat transfer
