    Abstract

    Melting and freezing of water in a spherical capsule is important in ice storage system which can considerably reduce peak electricity demand. Heat transfer within this process is quite complicated because of the two-heat transfer modes that occur namely, close-contact melting mode between phase change material (PCM) and capsule material and the natural convection heat transfer in melt pool under the solid PCM. Comparatively, the spherical capsule unit has a great advantage in terms of thermal performance and ease of installation than the cylindrical capsule type unit. Mathematical formulation and numerical results on the transient melting heat transfer in a spherical ice storage capsule are presented.
