Hydronic System Performance - Why Design and Modeling Data Cannot Alway Predict a Building's Actual Peformance

 

Description:

Energy and performance models make a few faulty assumptions about hydronic performance.  By understanding these assumptions, we can have a better view of actual performance.  This presentation will examine the performance impact of improper valve sizing, unstable system pressures and balancing device selection.  It also examines the physical effects of valve authority and coil degradation and presents technologies that can help resolve these issues.

  • Design and Modeling Assumptions
  • Hydronic heat transfer at the coil
  • Performance Problems
    • Valve Sizing
    • Static vs. Dynamic Balancing
    • Coil Performance
  • Potential Solutions
    • Pressure Independent Valves
    • Delta T Limiting strategies

 

Presented By:

The instructor is David Kandel. Mr. Kandel was one of the original development engineers in the Belimo control valve development group. He was an integral part of the group that developed the original CCV (Characterized Control Valve) and the PICCV (Pressure Independent Characterized Control Valve). Originally hired by Belimo in 1998, Mr. Kandel has held the roles of Manager of Valve Development, Product Manager for Control Valves and he currently works as a Regional Application Consultant for the Rocky Mountain region.
