Increasing ice production speed of a seasonal ice storage device
The speed of ice production within a seasonal ice storage device increased by a maximum of 28.77 %. • The use of a non-parallel structures is efficient for facilitating the ice production speed. • The heat transfer mechanism of
Major Benefits of Thermal Ice Storage
Thermal ice storage increases the energy efficiency of a building and the electricity generated to operate it. The efficiency increase is achieved by shifting the power
Performance optimization of a finned shell-and-tube ice storage unit
Abstract. The solidification enhancement of the finned shell-and-tube ice storage (STIS) unit with water is numerically analysed with consideration of natural convection. An unsteady model of the discharging process is presented to investigate the role of fin geometry in ice storage performance, which is validated by a discharging
Guidelines for improved performance of ice storage systems
Ice storage systems: ice-on-coil with internal melt, ice-on-coil with external melt, and dynamic ice harvester systems can be modeled by the plant model. •. Chiller types: vapor compression refrigeration cycle chillers with either centrifugal, reciprocating, or screw compressors can be selected within the plant model.
Comparing the economic performance of ice storage and
Ice storage has low initial and maintenance costs, but there is an efficiency penalty for charging of storage and it can only shift electrical loads associated
