Doug has interests and expertise in a number of areas related to industrial refrigeration systems that include system safety, optimization, assessment of design alternatives, conceptual design, energy conservation measures, system modeling, and field evaluation. As the founding director of the IRC, he leads the IRC's activities in the areas of research, knowledge transfer, and technical assistance for IRC members.
In addition to directing the IRC, Doug is a Professor in the College of Engineering with appointments in the Department of Engineering Professional Development (EPD) and Mechanical Engineering. Through EPD, he has developed an internationally-recognized series of ammonia refrigeration education programs. The ammonia programs provide attendees valuable information they can take back to their jobs for immediate application to improve the safety, efficiency, and cost-effectiveness of refrigeration systems. He has also led the development of a Process Safety Management "Best Practices" series of courses that provide state-of-the-art information on effectively managing refrigeration system safety.
He is a registered Professional Engineer in the State of Wisconsin, the immediate past chairman of ASHRAE's SSPC Standard 15 (Safety Standard for Refrigeration Systems), past chairman of ASHRAE Technical Committee 6.9 (Thermal Storage) and past vice-chair of ASHRAE GPC-2 - Engineering Analysis of Experimental Data. He is a member of commission D1 (Refrigerated Storage) at the International Institute of Refrigeration (IIR) and the International Institute of Ammonia Refrigeration (IIAR).
Todd has been at the IRC since 1997. All of his degrees are in mechanical engineering. Todd has extensive experience in modeling and analysis of industrial refrigeration systems with a focus on economics of energy efficiency measures . He is also interested in refrigeration load calculation, refrigeration system component modeling, accumulator design and the two-phase flow are some of his special interests in industrial refrigeration.
Todd is a member of ASHRAE and IIAR.
Todd has been involved in many site visits, and research including:
- Plant air balance issues and infiltration
- Safety relief vent piping analysis
- Applications of variable frequency drives (VFDs) to industrial refrigeration
- Desiccant dehumidification in refrigerated warehouse docks
- Effect of refrigerated warehouse dock conditions on total refrigeration system load
- Two-phase flow analysis of vertical suction risers in liquid overfeed evaporators
- Liquid-refrigerant droplet trajectories for design of both vertical- and horizontal accumulators
John holds dual appointments at the University of Wisconsin - Madison, College of Engineering. He is an Assistant Faculty Associate and Program Director in the Department of Engineering Professional Development and a Research Engineer at the Industrial Refrigeration Consortium (IRC). John's professional interests include HVAC products and systems, DX refrigeration, industrial refrigeration, geothermal system design, thermal systems optimization, building science and building energy management, technical leadership and project management. John is a member of ASHRAE.
Marc has been with the IRC since 2009 and is currently an assistant researcher. He is interested in energy efficiency, system modeling, and safety.
