The earthquake that struck Haiti in 2010 devastated the country and left many children orphans. Price is proud to be a part of the U.S. Green Building Council’s project to build Haiti’s first LEED Orphanage & Children’s Center.
Price’s Winder, Georgia Plant Manager, Steve Bittle, has had two opportunities to travel to Haiti since the earthquake. In the video below, he talks about his experiences and what Project Haiti means for the orphaned children in Haiti.
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.
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:
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.
When selecting a fan powered terminal unit (FPU) as a component in the overall building HVAC system, it is important to understand the differences in the motor technologies that are available. The type of motor–permanent split capacitator (PSC) or electronically commutated motor (ECM)–should be evaluated in terms of energy consumption characteristics and the cost differential/payback period due to energy savings is an important component of that selection.
Several local codes have adopted rules that limit the motor type in series FPUs to only ECM, but fail to address the motor type in the parallel FPU. At the national code level, there is some discussion on making the ECM motor the default type for use in series FPUs as well.
