Chillers are used to provide chilled water for air-conditioning systems, as well as for many industrial applications. Chillers come in a variety of compressor types: centrifugal, reciprocating, and screw being the major ones. In addition, users often specify multiple chillers for load diversity and therefore the question of series or parallel operation of the chillers has been debated over the years. Piping systems for chilled water have evolved from primary to secondary to tertiary pumping schemes. Understanding compressor performance, the refrigeration cycle, and its components is essential for selecting the right chiller for your application. It is essential to understand chilled water piping systems and part load chiller performance in order to make the right economic decisions in chiller installation and operation. This course will review refrigeration basics, general descriptions of chillers, chiller systems, chiller system auxiliaries, building operating dynamics, and the economics of chiller systems. |

Ronald H. Howell, P.E., retired Professor and Chairman of Mechanical Engineering at the University of South Florida, is a Fellow of ASHRAE, and member of ASME.
Dr. Howell began teaching in the field of mechanical engineering in 1959. For over 40 years, he has taught courses in refrigeration, heating and air-conditioning, thermal analysis, and related areas. He has had experience in the development of educational and experimental laboratory equipment, specifically with vapor compression refrigeration, air-conditioning process simulators, refrigerated air curtain test apparatus, and computer simulation techniques. His related industrial and consulting experience ranges from ventilation and condensation problems to the development and implementation of a complete air curtain test program.
Dr. Howell became a member of ASHRAE in 1969 and has served on the educational committee of the St. Louis Section,TC1.3, TC1.5, and TC4.7. Dr. Howell is past chairman of TC1.3 and SPC41.6. He has been principal investigator or co-principal investigator on 12 ASHRAE-funded projects. He has served on the Research and Technical Committee, the Accreditation Activities Committee, the Program Committee, and the Standards Committee of ASHRAE.
