A PHASE CHANGE MATERIAL (PCM) MODULE FOR A HEAT EXCHANGER APPARATUS FOR TEMPERATURE REGULATION IN A BUILDING

The present invention concerns a Phase Changing Material module for a heat exchanger apparatus, wherein the module comprises a first plate shell and a second plate shell, both shells having an undulated wave surface with a smooth, periodic oscillation, and wherein both said plates have a rectangular peripheral edge portion; and wherein said first and second plate shells are joined together along their peripheral edges to form an internal volume which is filled with a phase changing material.
