Dr. Orhan Ekren is Prof. in the Solar Energy Institute at Ege University. He received the M.Sc. degree from the Department of Energy Engineering, Izmir Institute of Technology, Turkey, and Ph.D. degree from the Department of Mechanical Engineering(Thermodynamics), Turkey. He has been working at Ege University with the 15 years of work experience. He studied as a Postdoc researcher in Southern Illinois University, USA and visiting professor in Cranfield University, UK as well. His main research interests are energy efficiency, energy saving, capacity modulation on refrigeration and HVAC&R systems, heat pumps, renewable heating and cooling, magnetic cooling, integration of renewable energy systems into buildings, optimum sizing of hybrid renewable energy sources(wind/solar etc.), also sustainability in energy and buildings. Dr. Ekren has authored and co-authored 48 international journal papers, 69 national/international conference papers, 13 books and book chapters and also 2 utility models on efficient operation of HVAC&R systems. Therefore, system design and experimental tests and demo studies are in my research scope. He has currently involved several research project funded by national research council (TUBITAK) and EC-FP7 project.

In the beginning, the sole purpose of utilization of the refrigeration was to conserve food (BC 1100). But today in our daily life, refrigeration is one of the necessary areas for the aim of not only food conservation but also comfort, industrial production, electronic equipments' performance, safe and proper operation of telecommunication stations and computer rooms, space studies, etc. The importance and wide application range of the refrigeration require new techniques and researches. In this respect, the scope and topics of the book are: Multistage refrigeration cycle analysis, Electrocaloric cooling method, Food chilling-freezing methods and equipments, CFD modeling of airflow in the display cabinet, Industrial application of refrigeration, Energy-efficient air-conditioning system comparison, Capacity modulation methods for energy-efficient refrigeration.
