Résumé

Different types of nucleation agents were used to achieve water nucleation under different coolant temperatures. The effect of the amount of nucleation agents on the freezing probability of cylindrical capsules was studied. The results indicate that the nucleation probability and nucleation temperature are higher than those of capsules containing pure water only. Silver iodide showed the best results in facilitating the nucleation. However, river sand is recommended as the nucleation agent because it is the most inexpensive and effective for the type of encapsulated storage tank used in a cold storage air-conditioning system.
