Kyle DelPiano Variable-Speed Pumping Control Strategies The design and operation of hydronic systems have changed drastically over the years. The control of the pumps can have a significant impact on system efficiency and over all building comfort. This presentation evaluates modern control strategies for variable speed pumping in HVAC hydronic systems by looking at how the control area or control curve and diversity of the system can cause coil flow misses when operating at part load conditions. This course will also examine variable speed curve control and area control strategies with guidelines on when to apply each. Speaker Bio: Kyle DelPiano is the business development manager, Commercial Buildings, for Xylem. In this role, he works with senior management of water technologies and other divisions to develop strategic direction for the company’s HVAC market. Kyle has nearly 12 years of experience in the HVAC industry in a variety of sales and training roles. Kyle graduated from Auburn University in 2007, with a bachelor of science degree in polymer and fiber engineering, concentration in mechanics. Prior to joining Xylem in 2014, he was a sales engineer with Trane/Ingersoll Rand from 2008-2014, applying his engineering skills and knowledge to the HVAC industry and combining that with his outgoing personality and natural ability to cultivate relationships. He is LEED AP certified and an active committee member of HIA-C Hydraulic Industrial Alliance. He is a frequent ASHRAE presenter and has been recently nominated to the ASHRAE Distinguished Lecturers Program. In addition to numerous technical presentations, Kyle has authored articles that have appeared in national industry publications on topics such as the advantages of hydronic systems versus variable refrigerant flow systems (VRF) as well as systems efficiency and modern pump selection. He recently authored an article on testing methods for new Department of Energy pump efficiency standards. Kyle co-developed Xylem’s Part Load Efficiency Value (PLEV) calculation, adapted from the AHRI IPLV standard load profile used for testing and rating chillers. PLEV is a standardized load profile that helps system designers calculate the energy consumption of the pump when a building’s actual load profile is not available to them. He espouses the benefits of mentorship for career and personal development, having been on the receiving end of great advice and feedback and also paying it forward by helping new engineers navigate the hydronic field. He’s passionate about helping people, whether that’s volunteering through his church, supporting Xylem’s corporate philanthropy program Watermark or working through a customer question about hydronic systems. He wholeheartedly believes his responsibility as an engineer is to never stop learning and to share his industry knowledge with those around him, inspired by the Auburn University creed: “I believe in education, which gives me the knowledge to work wisely and trains my mind and my hands to work skillfully.”

Brett Monteleone Centrifugal Chiller Operation and Efficiency Including a System Discussion on Optimization We will discuss the key drivers behind a centrifugal chiller’s energy consumption, along with design and operational decisions, that can help improve system efficiency. Speaker Bio: Brett Monteleone is the Regional Sales Manager covering the entire chiller line of business for the South Region. In his 15 years with York and JCI, he has held different local and regional positions in Orlando, Jacksonville and now works directly for JCI’s corporate headquarters in Milwaukee, WI. In his current role, he is responsible for the promotion and application of JCI’s entire portfolio of chillers and heat pumps. His career has been specifically focused on overall system optimization and design. He has supported the application of JCI’s chiller offering on projects throughout the USA and abroad in South America, North Africa, the Middle East and the Caribbean. Seawater cooled titanium centrifugal, radiator cooled centrifugal and waterside cascade are just a few of the unique project applications Brett has lead in his career. Brett holds a BSIE from the University of Florida and is a LEED Accredited Professional. MICROSOFT TEAMS FOR VIRTUAL MEETING ACCESSED HERE Learn more about Teams
