Coffee with Caleffi™
Recirculating domestic hot water in high rise buildings poses challenges that do not exist in lower profile buildings. Multiple floors contribute to high static head pressures which affect piping design and product selection. High-rise buildings must be "zoned" by groups of floors which typically means using multiple pressure reducing valves, circulators and sometimes heat exchangers. It gets complicated fast with varied design approaches.
Our guest speaker, Claudio Ardizzoia, Caleffi Global Headquarters Lead Product Manager, will share his 30+ years of expertise and experience in plumbing system and product design. He will discuss the challenges related to high-rise DHW recirculation, review solutions for proven design concepts and provide guidelines for proper product selection.
→ How does the static pressure in a high-rise building affect DHW recirculation design?
→ Is it possible to have one large recirculation loop or does it have to be divided into zones?
→ Where is the water heater (or water heaters) located in a high-rise?
→ Do I need to put pressure reducing valve in the recirculation piping?
→ How do I balance the recirculation risers in high-rise applications?
→ What about using master point-of-distribution mixing valves? Do I need one large valve or multiple smaller valves?
Ardizzoia is a mechanical engineering graduate, specializing in HVAC systems. His work experience includes design engineering, field management, technical documentation and his passion: R&D of new products and applications.
