Dr. Mir-Akbar Hessami received his BSc in Mechanical Engineering in 1976 from Kabul University, Afghanistan before going to North America. He completed his MSc/MEng degree in 1979 at the University of Hawaii, USA and his PhD in 1983 at the University of Calgary, Canada. He moved to Australia in 1983, and started working in the School of Mechanical and Manufacturing Engineering at the University of New South Wales. He then worked for BHP Research and Technology Centre between 1985 and 1987 before taking up an academic position at the Victoria University in 1987. In 1991, he started working at Monash University as a Senior Lecturer in the area of Energy Conversion and Heat Transfer. His research specialty in the mainstream engineering field is in the area of energy technology production, utilisation and conservation. Dr. Hessami has written many journal and conference papers on this topic. His recent research project has dealt with the performance of compact heat exchangers with specific focus on cross-corrugated plate heat exchangers. He is currently working on an experimental study of heat transfer enhancement in pipes caused by fluid pulsation. Dr. Hessami's area of teaching is in Heat Transfer, Thermodynamics, and Refrigeration and Air-conditioning. He has authored a textbook entitled Applied Thermodynamics: Power Production from Conventional and Renewable Sources.
Hybrid cooling systems could potentially save water. Water shortage is a major problem facing the power industry in many nations around the world. The largest consumer of water in most power plants is the wet cooling tower. To assist water and energy saving for thermal power stations using conventional evaporative wet cooling towers, a novel hybrid cooling system is investigated in this book.
Research on cooling systems to date has focussed on the individual components of cooling systems, not the system as a whole. Most of this research has been dedicated to cooling tower design and the optimisation of cooling tower characteristics. The issue of conserving water due to evaporation from existing operations has not been highly considered in the past. The major drawback in most of the previously conducted research in this field is the gap between maintaining energy efficiency whilst trying to reduce water consumption.
A hybrid cooling system consisting of a metal hydride heat pump and an existing cooling tower is described in this book. In addition to water saving, the hybrid cooling concept presented in this book also has the potential to improve energy efficiency and possibly reduce CO2 emission by recovering and upgrading the "waste" energy from the cooling water stream. This is therefore a win-win technology, producing both water and energy savings of significant quantities.
