Introduction of Dr. William Cousins:

William T. Cousins received his Doctoral degree from Virginia Tech and has worked in the area of axial and centrifugal compressor aerodynamic design, operability, and testing for over 30 years. As a principal investigator at UTRC, he currently leads the Carrier compressor technology development program and the NASA blended-wing-body embedded engine program, and has lead the NASA high-efficiency centrifugal compressor program, and other efforts. Spending much 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 in the aerodynamics area 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 has continued 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.

Abstract

The need for cooling in air conditioning, refrigeration, and industrial processes has 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.
