VAV boxes: Energy efficiency, air leakage, ASHRAE 90.1
This presentation discusses the results of ASHRAE RP-1292, which discovered the excessive amounts of leakage in typical parallel boxes, and changed the notion of them being more efficient than series boxes.
This presentation discusses the results of ASHRAE RP-1292, which discovered the excessive amounts of leakage in typical parallel boxes, and changed the notion of them being more efficient than series boxes. The significant differences between ECM and PSC motors will be discussed, showing the major energy advantages of the ECM and when those benefits are realized. Finally, the requirements of ASHRAE 90.1 regarding VAV boxes are discussed as well as the relationship between AHRI and ASHRAE to meet these requirements.

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
