Design for Realistic Constraints: Challenges in Chiller Design for Building Cooling

Release Date:
9/3/2013 12:00 AM

William Cousins, features William T. Cousins


The Alvine Engineering Professional Effectiveness and Enrichment Program will present a lecture by William Cousins, Ph.D. on the need for cooling in air conditioning, refrigeration, and industrial processes have developed into a technology that is a necessity in the world today.  The challenge of meeting the cooling needs of the modern industrial world while considering the impact of refrigerants on the world climatology will be discussed.  Basic chiller components and operation will be reviewed and the impact of refrigerant types, as discussed in the laws developed from the Montreal and Kyoto Protocols, will be reviewed.  The constraints of using different refrigerants and the impact on the design of the chiller system will be presented.  Technology challenges exist due to these design constraints and the presentation will focus on a few of the areas presently being addressed.   


Dr. Cousins holds B.S., M.S., and Ph.D. degrees from Virginia Tech, and is presently with United Technologies Research Center as a Principal Research Engineer in the Thermal & Fluid Sciences Department. As a principal investigator, he works primarily in the aircraft propulsion area and in the compressor technologies associated with industrial chiller units.

He has worked in the area of axial and centrifugal compressor aerodynamic design, operability, and testing for over 30 years. Spending most of his career in the propulsion industry in both a managerial and individual contributor capacity, he has also worked in the power production and air pollution control businesses. Dr. Cousins has performed research and published extensively and has spent a large portion of his time in the area of axial and centrifugal compressor design, testing and measurements, inlet/engine integration, inlet distortion, stall and surge phenomena, and unsteady flow analysis. 

He continues to teach undergraduate and graduate technical courses as an adjunct professor at the University of Hartford and at Rensselaer Graduate Center in Hartford, and as a corporate certified facilitator, has taught courses in process improvement, culture change, and six-sigma quality. Listed in Marquis' Who's Who in Science and Engineering and Who's Who in the West, and also Strathmore's Who's Who, Dr. Cousins has received numerous awards including the Certificate of Teaching Excellence from Virginia Tech, the Adjunct Professor of the Year from the University of Hartford, the NASA Glenn Team Recognition Award, the Honeywell Corporate Technical Achievement Award, and the ASME Dedicated Service Award. Dr. Cousins is a Fellow in ASME and has held numerous positions including Vice President, Senior Vice President, and Governor, in addition to chairing the Aircraft Engine Committee of International Gas Turbine Institute.

Founded in 1920 on the campus of Yale University in cooperation with Northeastern University, UNH moved to its current West Haven campus in 1960. The University operates a satellite campus in Tuscany, Italy, and offers programs at several locations throughout Connecticut and in New Mexico and California. UNH provides its students with a unique combination of a solid liberal arts education and real-world, hands-on career and research opportunities. The University enrolls approximately 6,400 students, including nearly 1,800 graduate students and more than 4,600 undergraduates – the majority of whom reside in University housing. Through its College of Arts and Sciences, College of Business, Henry C. Lee College of Criminal Justice and Forensic Sciences, Tagliatela College of Engineering, and College of Lifelong & eLearning, UNH offers 75 undergraduate and graduate degree programs. UNH students have access to more than 50 study abroad programs worldwide and its student-athletes compete in 16 varsity sports in the NCAA Division II’s highly competitive Northeast-10 Conference.
