The global ac drives market is expected to grow from an estimated $15.72 billion in 2016 to $22.07 billion by 2021, registering a compound annual growth rate (CAGR) of 7 percent from 2016 to 2021, according to a report from MarketsandMarkets.
Driven by variable-frequency drives, the Gen2.0 PremiumPlus+™ brushless permanent magnet motors have motor-only rated point efficiencies of 93 percent and 92 percent for 3- and 5-hp versions respectively. They are packaged in standard NEMA frame sizes and mounting dimensions for easy substitution.
The Danfoss VLT® HVAC Basic Drive, designed specifically for HVAC OEMs, is ultra compact, robust, with lowest installed cost, offering reliability, low noise, connectivity, user friendliness/simple commissioning, highest efficiency and integrated harmonic filtering, the company says.
Time of use (TOU) rate structures have long been touted as a necessity for utility companies to incentivize homeowners and building owners enough to embrace demand response systems. According to John Galyen, president of Danfoss North America, “Smart meters will change the game.”
When it comes to motors, drives, and variable speed technology, manufacturers keep rolling out new products designed to increase efficiency. Here are just a few of the latest offerings that contractors may want to consider.
A preventive maintenance program at a leading New England Ivy League university demonstrates how the push for more sustainable building management has led to a growing awareness of a chronic, widespread problem for HVAC motors: electrical bearing damage.
