Hydronic systems offer commercial building owners and industry professionals the opportunity to both take baby steps and long leaps toward achieving net zero carbon emissions.
The ASHRAE 2023 Handbook HVAC Applications is now out, and we need to get ready to revise it again. Updated every four years, this volume is significantly larger than its previous editions, in part due to a new Chapter 66, In-Room Air Cleaners.
Bypass pipes, accompanied by a three-way control valve, are often seen in hydronic systems at both served loads (e.g., reheat coils) as well as at primary equipment (e.g., cooling towers).
This new solution reduces maintenance, noise while increasing efficiency.

These six case studies, covering just the last three years, illustrate how bad second-order effects can get when there are problems with the bypass pipe’s balancing valve.
