Technical Presentation Highlights:

Methods and Cooling Loads Encountered in the Ice Cream Industry

Production of ice cream is one of the more refrigeration energy intensive processes for dairy-related products.  With an emphasis on refrigeration, this presentation will describe the basic processes and steps involved in the production of ice cream.  Examples of the main refrigeration product loads for each of the ice cream process steps will be provided and estimates of the total product loads associated with producing a gallon of ice cream presented.


Douglas Reindl is a professor and chair with appointments in the Department of Engineering Professional Development and Mechanical Engineering at the University of Wisconsin-Madison. In addition, he is the founding director of the Industrial Refrigeration Consortium (IRC) at UW-Madison. He received his B.S. in Mechanical Engineering Technology from the Milwaukee School of Engineering and his M.S. and Ph.D. degrees from the University of Wisconsin-Madison. He is a registered professional engineer in the State of Wisconsin and actively involved in ASHRAE, IIAR, and IIR.

As faculty member at the University of Wisconsin since 1996, Professor Reindl has taught at all levels: undergraduate, graduate, and continuing professional development. Professor Reindl has developed an internationally-recognized series of professional development courses focused on industrial refrigeration systems with an emphasis on the safe use of ammonia as a refrigerant. Through the IRC, Professor Reindl collaborates with the world’s leading food companies to improve the safety, efficiency, reliability and productivity of industrial refrigeration systems and technologies.

Professor Reindl is an ASHRAE Fellow and a past recipient of ASHRAE’s Distinguished Service Award. HE was the first recipient of ASHRAE’s George C. Briley Award for the best refrigeration article in the ASHRAE Journal. He is a past chair and currently serves as a member of ASHRAE’s Standard 15 committee – Safety Standard for Refrigeration Systems. Professor Reindl has published 7 books and over 100 technical papers on topics including: industrial refrigeration, building mechanical systems, energy systems, and solar energy.


Main Presentation Highlights:

Indoor Air Quality During Construction

Indoor air quality problems can be difficult to solve. An IAQ problem can ruin a building’s reputation and it can take years to turn that around. Some IAQ problems get their start during construction.

This presentation will look at the standards and guidance documents on IAQ and how those can be used in design and construction. Sharon will discuss, for each type of air contaminant, the sources, the options and challenges of measurement techniques, and the criteria for acceptability. The requirements from the air quality testing option for LEED will be compared to what is typically detected in a new building.

Finally, the importance of infection prevention and an Infection Control Risk Assessment (ICRA) during construction and renovation of healthcare buildings will be emphasized. Sharon will describe how these same principles can be used to prevent contamination problems in construction and renovation of biotech facilities.

Sharon Bessa began her career as a nurse, graduating from the University of Wisconsin in Madison and is grateful every day for the path that led to a career in Industrial Hygiene. Who else, she says, gets to watch appliances assembled, truck parts welded, metal castings sand-blasted, drugs manufactured, and a tonsillectomy – all in the same week?! And she gets to go behind all those doors that say “Authorized Personnel Only!”

Sharon worked for OSHA for seven years before starting her own business over 30 years ago. In addition to taking air samples in manufacturing environments, Sharon has completed air quality studies in a very wide variety of worksites including schools, hospitals, clinics, casino security suites, department stores, animal research rooms, correctional facilities, and, of course, office buildings. She has been responsible for oversight of numerous water damage restoration and mold remediation projects. She has done the air sampling required for LEED certification and participates as part of the commissioning team for air quality and infection prevention during construction of healthcare facilities. She has been an instructor on IAQ for the Building Operator Certification program for the Midwest Energy Efficiency Alliance and Focus on Energy for over ten years.

Sharon is a member of ASHRAE, IFMA, APIC (Association for Professionals in Infection Control and Epidemiology), AIHA, and is President Elect of the Wisconsin Local Section of the American Industrial Hygiene Association.

Sharon has one daughter and four grandchildren. In her spare time she likes to golf, kayak, and recently retired from 27 years on ski patrol.
