The International Refrigeration and Air Conditioning Conference covers a wide range of topics of interest to researchers and engineers involved in the development of technology improvements and/or assessments of air conditioning and refrigeration equipment. In 2010, proceedings for this conference included 156 papers from authors all over the world. For 2012, we are soliciting papers on topics ranging from fundamental to applied, including heat transfer and fluid flow fundamentals, alternative refrigerants and working fluids, modeling of components and systems, heat exchanger enhancements and characterizations, controls, diagnostics, domestic, commercial and industrial refrigeration, heat pumps, transport refrigeration and air conditioning.”
