What is ice storage?

The expression “ice storage” commonly defines thermal storage employing the enthalpy difference of water during its phase change from liquid to solid . The high latent heat of fusion of water results in a higher energy density for this type of storage compared to water-based sensible storage, leading to smaller volumes.

How to assess seasonal performance of ice storage?

Other two indicators have been used to assess the seasonal performance of the ice storage. Its seasonal efficiency η s t is defined as the ratio between the heat rejected into the storage via the bypass pipe on the upstream branch (u b p) and the heat extracted by the water-to-water heat pump, i.e., the heat flowing through the downstream pipe (d).
