Hello everyone!

I have added Phase Change Materials (PCMs) as cold thermal energy storage (CTES) to the inner surface of the walls in a refrigerated warehouse. The PCM has a melting point of -20°C, the Enthalpy-Temperature function is shown in the Fig. 1 below.

I then set the Zone Phase Change Material Melting/Freezing Enthalpy as outputs. However, the enthalpies were both equal to zero (Fig.2).

Does anyone have any idea why Zone Phase Change Material Melting/Freezing Enthalpy is equal to 0?

Do I need to 0? define a specific zone for the PCMs?
