Andrei Hari
Andrei Hari has worked a combined 21 years with Armstrong Fluid Technology. He currently holds the title of Canadian Business Development Manager, concentrating on educating the industry on a systems approach to chilled water, geothermal, heat pump and boiler plant optimization with a focus on an understanding of Demand Based Controls, Digital twins, and the application of
AI, along with the importance of flow control. He has also held roles as US North Central Regional Sales Manager, US National Commercial Sales Manager and US National Sales Manager / Large Projects.
He is a graduate of Ryerson University, with a Mechanical Engineering degree. He has over 30 years of experience in Industrial, Municipal and HVAC pumping and Industrial and Commercial Heat Transfer applications. With this experience, he has spent the last 16 years developing an intricate understanding of HVAC optimization strategies and load distribution systems. This combined experience gives him a unique insight, not only into the mechanical side of Commercial HVAC applications but also a unique perspective on a systems solution approach to flow control, chilled water plant automation and optimization with Demand Based Control methodology, applying Armstrong Fluid Technologies Design Envelope solutions, all based on the basic engineering fundamentals of Fluid dynamics, Heat transfer and Thermodynamics.
Primary Topics:
Variable Flow Control, Affinity Laws, Pump Efficiency and Parallel pump staging, Design for N+1 and system redundancy
Agenda
1. Brief review of how variable speed pumping works. This will cover an understanding of the pump, system and control curves and a review of the Affinity Laws.
2. ASHRAE 90.1 and the importance of DP switch location in a closed loop system.
3. Explanation of how sensorless pump control works.
4. Parallel Pump Control and efficiency-based staging.
5. Duty/Standby (N+1) vs. Operational Redundancy pumping system selection and design.
