dear Jim and Achim,
I developed a pcm enhanced storage tank, but it features vertical cylinders filled with PCM designed for heating and DHW production. The model was present in the old Roberta_Padovan branch, however I think the model is not suited for ice storage, because usually the ice develop inside the tank, not in separate immersed modules, and ice layers grow around heat transfer coils.
