Summary

This article experimentally investigates the thermal performance of a thermal battery used in the ice storage air-conditioning system as a subcooler. The thermal battery utilizes the superior heat transfer characteristics of two-phase closed thermosiphon and eliminates the drawbacks found in convectional energy storage systems. Experimental investigations are first conducted to study the thermal behaviour of thermal battery under different charge temperatures (-5 to -9°C) in which water is used as the energy storage material. This study also examines the thermal performance of the subcooled ice storage air conditioner under different cooling loads. Experimental data of temperature variation of water, ice fraction, refrigerant mass flow rate and COP are obtained. The results show that supercooling phenomenon appears in the water and it can be ended when the charge temperature is lower than -6°C. The system gives 28% more cooling capacity and 8% higher COP by the contribution of the thermal battery used as a subcooler.
