Preface

The authors strive to provide a comprehensive background and thorough understand-

ing of the thermodynamics of working ﬂuid mixtures and their applications in vapor

compression systems. The information presented here is based on an extensive

review of the literature and includes a considerable body of experience gained by

the authors from over two decades of research in the laboratories of CEEE at the

University of Maryland, the National Institute of Standards and Technology (NIST),

and the Oak Ridge National Laboratory (ORNL). To ensure that this text is com-

prehensive and up to date, the authors invite all interested parties to submit correc-

tions, recommendations, and suggestions for improvement to Reinhard Radermacher

at raderm@eng.umd.edu or Yunho Hwang at yhhwang@eng.umd.edu.

department of mechanical engineering, works with Dr. Radermacher in the Center

for Environmental Energy Engineering. Dr. Hwang’s career began as a senior

researcher at Samsung Electronics in Korea, and he has devoted more than 20 years

to university and private industry research. Dr. Yunho Hwang, Director of the Heat

Pump Laboratory (CEEE), is an internationally recognized expert in energy conver-

sion systems; in particular, heat pumping, air conditioning, and refrigeration systems.

He has coauthored 3 books and written more than 50 academic papers. He currently

serves as secretary of the IIR (International Institute of Refrigeration) Commission B2.

is a professor of mechanical engineering at the Uni-

versity of Maryland and director of the university’s Center for Environmental Energy

Engineering (CEEE). His engineering expertise, spanning over two decades, is

concentrated in energy conversion, renewable energy, heating and power systems,

and air conditioning and refrigeration.

Dr. Radermacher is a graduate of the Munich Institute of Technology, Germany,

and has worked with numerous private energy corporations, as well as government

institutions and engineering groups. He currently serves as editor of ASHRAE’s
