Single phasing often occurs in an electric motor when one pair of points on its power contactor fails because of the destructive arcing that takes place each time these points open or close. This arc suppressor is designed for AC power applications that operate between 110-480 V and have a maximum allowable current of 235 A (rms).
Energy efficiency, the growing popularity of ductless and variable refrigerant flow (VRF), the evolution of heat pumps into whole-home solutions, and the Internet of Things (IoT) are a few of the major trends influencing products in the residential air conditioning market.
The Green Tech Line of refrigeration and air conditioning components is designed for use with natural refrigerants R-290 (propane), R-600a (isobutane), and R-744 (CO2). These high-quality, hydrocarbon (HC) and CO2-ready system components include valves, controllers, transducers, filter driers, and microchannel heat exchangers.
The decision to use air conditioner manufacturer NOVA was easy to make
January 23, 2017
Some situations require new ways of thinking — and setting up the air conditioners on the roof of the ebm-papst location in Hagenmoos/St. Georgen was one of them. The factory hall is simply too large for conventional setup with a crane. They would have had to build an access road especially for the crane. Instead, they decided to transport the five air conditioners to the roof via helicopter.
Ensuring effective education and troubleshooting services
January 18, 2017
In an effort to provide customers with high-quality training and support to efficiently and effectively manage their HVAC systems, LG Electronics USA has opened a new, 4,100-square-foot HVAC training academy in Orange County, California, with interactive courses on the latest LG technologies.
In this troubleshooting problem, it’s the middle of July, and you are the follow-up technician on a callback. The original complaint was a “no cooling at all” call, and the technician who preceded you on this job (we’ll call him Technician #1) has only limited experience, but he reported correctly that he found a failed transformer and replaced it.
Data center optimization company stresses importance of a thermal strategy to avoid outages
January 9, 2017
With thermal risks still accounting for 29 percent of unplanned data center outages, data center optimization company, EkkoSense, has detailed how organizations need a more structured thermal approach to kick their addiction to over-cooling — cooling now accounts for 35 percent of overall data center energy consumption.
The Bard MULTI-TEC gives you the ability to link up to 14 wall mount air conditioners to a single intelligent building control. It only takes two wires to each air conditioner, and your entire building can be up and running.
