Carlo Renno is professor of Applied Thermodynamics and Heat Transfer at University of Salerno (Italy). Author of over 70 technical-scientific papers which other papers published on international journals with referees and other papers presented to international congresses. Responsible or participating of different research projects. He has developed his research activity in the field of Applied Thermodynamics and Heat Transfer, with a particular attention to the study of the vapour compression and solar cooling systems both from the experimental and theoretical point of view. At the moment the aim of the research study is the theoretical and experimental analysis of solar systems able to obtain both electrical energy and thermal energy, such as the Concentrating Photovoltaic and Thermal (CPV/T) systems both line-focus and point-focus.
