and he developed modifi ed Mollier diagrams taking into account the presence of oil. After
2 years spent teaching and performing research at the Institut Français du Froid Industriel (IFFI),
he is now head of a research project at Cemagref in Antony, France: his focus is on eco-design
of refrigeration systems and the energy effi ciency of the exchangers used in the systems. Author
of more than 30 scientifi c and technical publications illustrating his work in the refrigeration fi eld,
Mohammed ***** also teaches in many engineering schools and universities on a regular
basis. He is a junior member of the IIR’s Commission B2, a member of the French Refrigeration
Association (Association Française du Froid - AFF) and is on the editorial board of the Revue
