Abstract: In this study, a practical ice-slurry thermal energy system is considered to meet a building's cooling demands. Hourly system analyses are conducted, including total work and heat loads, rate of exergy destruction, exergy efficiency and COP. The effects of varying ambient conditions on the charging, storage, and discharging periods are also investigated. Exergy destruction and exergy efficiency concepts are studied to consider irreversibilities to address the consequences of non-conservation of exergy. Focusing at different times, cooling demands, and identifying the exergy efficiency and destructions at charging at discharging periods and the system's exergetic performance give an idea about 'the availability of work' lost in different subunits and at different ambient temperatures. The results show that during the peak cooling demand of the residential unit, the rate of exergy destruction is about 64 kW, the exergy efficiency is about 47%, and the highest COP becomes about 2.45, respectively.
