A Study on the Cool Charge Characteristics of Ice Storage Plate Filled with Eutectic salt

摘要

The electricity load imbalance between day and night of air conditioning greatly affect the power generation cost and safe operation of power grid. Because of the important role in balance the peak and night electricity load, the Cool storage technology more and more attention at home and abroad. A cool storage experimental apparatus with internal melt ice-on-coil was set up, and on which the heat-transfer characteristics have been determined. The experimental results show that: The inlet temperature of refrigerant, when entering the ice storage tank, has an larger influence on the process of cool storage than the flow amount of the cooling medium. It is found by analyzing the process of experiment about storage that the suitable outlet temperature of the cooling medium is 1C while the flow amount of the cooling medium is 0.274 m~3/h. The research results can provide help for the energy-saving design of air conditioning.
