A comparative study on PCM and ice thermal energy storage tank for air-conditioning systems in office buildings …

The energy storage efficiency is enhanced from 0.470 to 0.772, while energy storage density based on fluid and setup volume are increased by 78.62% and 120.90% respectively. The charging/discharging rate and solution concentration glide increase continuously as the heat source temperature rises from 75 °C to 100 °C, leading …

Thermal Energy Storage | Department of Energy

Thermal energy storage (TES) is a critical enabler for the large-scale deployment of renewable energy and transition to a decarbonized building stock and energy system by 2050. Advances in thermal energy storage would lead to increased energy savings, higher performing and more affordable heat pumps, flexibility for shedding and shifting building …

Predictive model of cooling load for ice storage air-conditioning system by using GBDT …

The ice-storage air-conditioning system uses refrigeration units for cooling during the night when the electricity price is low, and freezes the water in the tank into ice to store cold. During the high electricity price period during the day, the cold energy in the ice storage tank is released to meet the cold load demand in commercial buildings.

Need for thermal-storage air-conditioning in Saudi Arabia

9.3. Saving on the maintenance cost. The average cost of maintaining an air-cooled chiller unit in Saudi Arabia is about SR 100 per kW (cooling) per year, based on 20 years of useful chiller-life. A reduction of 1820 kW (cooling) in the chiller capacity will reduce the yearly maintenance cost by SR 182,000.
