Dr. Piotr A. Domanski

Piotr A. Domanski is the leader of the HVAC&R Equipment Performance Group of the Energy and Environment Division (EED) of the Engineering Laboratory (EL). Dr. Domanski completed his Doctoral Dissertation at the National Institute of Standards and Technology (NIST) on the modeling of vapor compression heat pumps. He remained with NIST and expanded the heat pump model, HPSIM, to include zeotropic mixtures and evaluate mixture potentials as compared to single-compound refrigerants. Prior to the modeling assignment, he was responsible for heat pump testing in the environmental chambers, which has given him insight into the physical behavior of heat pump to support the modeling work.

The development of air conditioner and heat pump rating procedures was one of several assignments of Dr. Domanski. The rating procedure for variable-speed equipment and for mix-matched air conditioners was developed under his direction. Dr. Domanski also conducted research on alternative refrigerants and is the principal author of CYCLE-11, CYCLE_D, and EVAP-COND simulation models. He is a co-holder of two patents on expansion devices. Currently, Dr. Domanski's research focuses on the development of measurement science needed to improve the performance of air-conditioning and heating equipment for application in both current buildings and net-zero energy structures. His main interest is in advanced simulation models, evolutionary computation-based optimization methods, automated commissioning, and fault detection and diagnostics. In addition to his studies, he is a co-lead of the EL Net-Zero Energy, High-Performance Buildings Program, which encompasses technologies for reducing cooling and heating loads in buildings, air conditioning, renewable and distributed energy technologies, and energy efficient lighting.

Dr. Domanski is a member of the American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc. (ASHRAE) and International Institute of Refrigeration (IIR). In the past he was a member of the ASHRAE Standards Committee and Research Administration Committee. He served as the President of IIR Commission B1 on Thermodynamics and Transfer Processes, the Regional Editor for the Americas of the International Journal of Refrigeration (IJR), and was a member of the IJR International Advisory Board. Currently, Dr. Domanski serves as the President of the IIR Science and Technology Council. He chaired the 1997 ASHRAE/NIST Refrigerants Conference and co-chaired the 2009 3rd IIR Conference on Thermophysical Properties and Transfer Processes of Refrigerants and the 2012 ASHRAE/NIST Refrigerants Conference.

Dr. Domanski received a Bronze Medal Award from the U.S. Department of Commerce in 1992, NIST's William P. Slichter Award in 1995, the Award of Excellence for a Technical Paper at the 2002 International Appliance Technical Conference, the IIR Science and Technology Medal in 2003, Silver Medal Awards from the U.S. Department of Commerce in 2005 and 2009, the Diploma of Honor "Academician Emeritus" from the International Academy of Refrigeration, St. Petersburg, Russia, in 2009, the Wilbur T. Pentzer Achievement and Leadership Award from the U.S. National Committee of the IIR in 2012, the 2013/2014 Best Paper Award from the International Journal of Refrigeration, and the Best Paper Award for 2014 from the International Journal of HVAC&R Research. He is an ASHRAE Fellow and a recipient of the 2007 ASHRAE Distinguished Service Award. Please feel free to contact Dr. Piotr Domanski with any technical inquiries.
