The ice-on-coil storage tank is one of the core devices in the latent heat cold storage system. The main objective of this study is to couple the solar photovoltaic cold storage with Cold Thermal Energy Storage technology. The internal ice-melting coil energy storage system used the water as a heat transfer fluid for adopting a day and night cold storage control strategy. The experiments were conducted for several days under the conditions of photovoltaic-driven cold storage with and without load for a continuous cold storage. The reasons for the occurrence of ice layers during ice accumulation and melting

as well as the operational economy of the system were analyzed. Moreover

the characteristics of the cold storage tank were summarized. Consequently

when the external ice thickness of the coil was within the range of 27 to 32mm

the ice storage rate reached 35.82% and achieved the optimal refrigeration efficiency in both the coil and the cold storage. The daily ice production in the cold storage tank decreased by an average of 22.06% during continuous operation with load compared to the unloaded operation. However

the daily refrigeration capacity increased by 45.774%. In addition

when cold thermal energy storage was coupled with solar photovoltaic technology

the refrigeration capacity decreased by 7.15% compared to using Cold Thermal Energy Storage technology alone

which resulting in an annual electricity cost saving of 30.20%.
