Hello scientific community,

When the compression refrigeration machine's coefficient of performance (COP) formula is expressed as:

COP= Q_col/W

With:

Q_col is the quantity of heat exchanged in the cold room.

W is the work required to power the refrigeration system's compressor.

How do you calculate the coefficient of performance (COP) of a compression refrigeration system that incorporates thermal storage endowed with a eutectic phase change material (such as liquid KCl)?

With the best regards.
