The Story of The Handbook

Over the past two years 50 Price staff members have been working relentlessly on the first-ever Price Engineer’s HVAC Handbook—a groundbreaking industry resource that combines the application of fundamental HVAC concepts with field experience and design guidance.

This 1,300 page reference text  features 99 examples, 15 research highlights and over 1,000 graphics to help explain concepts and systems, our hope is that this handbook will be of benefit to all practicing engineers in the air distribution industry, as well as architects, contractors, students, and anyone else interested in HVAC systems.

The journey from inception to print was enjoyable and thoroughly educational for everyone on the Handbook Team. Now that the first shipments have been sent to Reps and 10,000 personalized books will be hand-delivered to engineers across North America in June, we’d like to share a behind-the-scenes look at the making of the Price Engineer’s HVAC Handbook.

Without further adieu, we give you the Lead Engineer on the Project, Julian Rimmer.

Enjoy!

Terminal Unit Sizing – Inlet Valves

All variable air volume (VAV) terminal units—including single duct, bypass, system powered induction, fan-powered or dual duct—have a common function: regulate the amount of primary air entering the terminal unit.

This control of the primary air volume can be used for the following purposes:

  • Occupied space temperature regulation
  • Discharge air pressure regulation
  • Discharge air temperature regulation
  • Mixing of primary air with return air in an induction terminal

The primary air valve assembly contains an inlet tube, damper and air flow sensor. When sizing a terminal unit inlet, HVAC designers aim to minimize the sound generation of the terminal unit, as well accurately resolve the flow signal at both full and minimum cooling.
