Embraco introduced the Plug n’ Cool sealed unit line during the 2016 AHR Expo. This is described as a complete cooling solution focused on commercial refrigeration.
“Embraco’s Plug n’ Cool solution is a prime example of how a store owner can take advantage of advanced technologies while remaining environmentally conscience and reducing long-term utility costs,” says Doug Schmidt, Commercial Sales Manager for the North American Region.
The Plug n’ Cool is an R290 pre-charged sealed system designed for top-mounted reach-in coolers for grocery stores, supermarkets and professional kitchens. Due to its modular concept, this product allows owners to move machines piece by piece, providing flexibility in the store layout based on specific needs and preferences.
The Plug n’ Cool provides a “plug n’ play” solution that simplifies the installation process, allowing design engineers to easily build market-ready, water-cooled display systems. It also decreases maintenance costs by allowing retailers to maintain the systems themselves, eliminating the need to consult refrigeration technicians. Store owners simply need a sufficient water supply and return lines to cabinets in order to run their cooling systems. This innovation decreases the amount of downtime and potentially spoiled products, sources report.
Emerson Climate Technologies, Inc., a business of Emerson has launched the second generation of its Copeland Scroll variable speed ZPV2 compressor and EV2 motor control drive for residential and light commercial applications. Emerson’s Copeland Scroll variable speed technology was named Product of the Year at the 2014 AHR Expo. The second generation Copeland Scroll variable speed ZPV2 compressor features intermediate discharge valves to boost efficiency, optimized scroll elements for variable speed performance, positive displacement oil pump for enhanced reliability in low speed operation and brushless permanent magnet (BPM) motor technology for maximum efficiency.
Integrated CoreSense technology is built into the new Copeland Scroll variable speed EV2 motor control drive for optimal compressor performance.
New Danfoss scroll compressors with Intermediate Discharge Valves (IDVs) will soon be available in cooling capacities from 7.5 to 40 tons and offer new features and options that deliver the most cost-effective solution for the next generation of rooftop units and chillers with R-410A.
IDVs allow the compressor to avoid over-compression losses and, thus, extra work by the motor during part-load operation—enabling Danfoss Scrolls DCJ and DSH to save energy and improve IEER and IPLV up to nine percent. Plus, Danfoss Scrolls with IDVs are backward compatible with the existing Danfoss SH range, leading to minimal redesign and implementation costs.
Danfoss scroll compressors with IDVs include additional tandem and trio combinations, an extension of the operating map, improved liquid handling capability, and a patented, more robust oil management method in manifolding applications.
Danfoss Scrolls DSH with IDVs received Honorable Mention in the Cooling category of the 2016 AHR Expo Innovation Awards program.
Tecumseh VSC Series Scroll compressors are now available in R404A commercial and low temperature models up to 10 HP. VSC series scrolls are considered “drop in” replacements, since they have the standard mounting footprint, overall height, rotolock connections, tubing orientation and performance characteristics of competitive models. As universal replacments for original equipment compressors, the VCS series scroll compressors feature standard mounting footprints, and overall height and rotolock connection and size orientation. Tecumseh claims the compressors meet or exceed performance characteristics of competitive models. Built-in reliability is provided due to the scroll design and engineered bearings. Thermal fault protection contributes to excellent reliability.
Bitzer showcased its line of advanced refrigeration compressor products during the 2016 AHR Expo. Among those products are the Bitzer ORBIT scroll compressors, which have high isentropic efficiency, low sound levels and excellent energy efficiency. With displacements between 11.8 and 22.4 CFM for the ORBIT 6 and between 17 and 45 CFM for the ORBIT 8, BITZER scroll compressors offer a wide range of applications. ith the BITZER Advanced Header Technology (BAHT), ORBIT scroll compressors can easily be connected in parallel into groups of two or three units (shown above), and that is even possible with differing compressors or if one is frequency-controlled. Bitzer sources say the BAHT system is unique in that it also works with either uneven capacity scroll compressors in one unit or with fixed, plus variable speed combinations of compressors. The system also offers another major advantage: active oil management with an oil separator is no longer necessary.
