September Program- Thermal Displacement Ventilation
September 15, 2020 @ 12:00 pm - 1:00 pm
The Wisconsin Chapter of ASHRAE is proud to announce that on September 15th we will kick off our fall 2020 speaker series with Dr. Andrey Livchak who will be presenting “The Fundamentals of Thermal Displacement Ventilation”. Dr. Livchak will also be discussing the ASHRAE recommendations for HVAC systems during the Covid-19 pandemic.
Dr. Andrey Livchak has over 30 years of international experience in the HVAC industry. He graduated from Moscow Civil Engineering University in 1983 with honors and M.Sc. degree. In 1989 he received Ph.D. in engineering from the same university. His expertise covers several areas including air distribution, heat recovery, cooling, heating systems, acoustics and commercial kitchen ventilation. Dr. Livchak started his engineering career in 1983 in Moscow working at the government research laboratory. He joined Halton in 1989 working first in its European division and in 1998 moved to the U.S. to manage Halton R&D center. In his current position as the Director of Global R&D for the Foodservice division, Dr. Livchak is responsible for planning and coordinating research and development of five Halton Research Centers in America, Europe and Asia. Dr. Livchak is an active AHRAE member, he works on TC 5.3 (Air Distribution) and SPC-200 Method of Testing Chilled Beams committees, has over 50 publications including more than 20 patents.
Thermal displacement ventilation (TDV) is a unique system that saves energy and, at the same time, improves indoor environmental quality of HVAC systems in cooling applications. This presentation will give classification of air distribution systems in terms of temperature and CO2 concentration; it will describe fundamental differences between TDV and Mixing Ventilation. It will explain how ASHRAE Standard 62.1-2010 impacts TDV system design and describe benefits and limitations of TDV. It will also cover TDV performance when space heating is provided by secondary heating systems and when displacement diffusers are used for space heating in all-air systems.
PDHs will be issued via email after the presentation.
This presentation is approved for GBCI and AIA CEUs
