Building Automation and Refrigeration Products Feature Energy Efficiencies

Danfoss building automation and refrigeration products are recognized for energy efficiencies.

Danfoss building automation and refrigeration products are recognized for energy efficiencies.

Danfoss has been recognized by a panel of ASHRAE members in the 2017 AHR Expo Innovation Awards program. Danfoss Enterprise Services and Danfoss CTM multi-ejector both won top honors in the building automation and refrigeration categories, respectively. In the green building category, the Danfoss Turbocor TG compressor was named an Honorable Mention.

As the winner in the award competition’s building automation category, Danfoss Enterprise Services is a cloud-based service delivery platform tailored to supermarket and other food-retail applications that collects a range of data points from connected devices to provide insight into nearly every aspect of HVACR operations, energy management and usage, benchmarking, and food safety.

Danfoss Enterprise Services provides real-time information to monitor equipment alarms, compressor status, leak detection, food temperatures, and refrigerant levels. Other services are also available for energy base-lining and benchmarking usage, demand response, and remote assist to promote energy efficiency and savings, while helping to troubleshoot and adjust overall HVACR system functions.

This service helps facility personnel, store owners and management make decisions to maximize energy efficiencies and cost savings, optimize food safety, and reduce environmental footprint by utilizing connected devices and data.

An electrically controlled multi-ejector designed specifically for the warm climate operation of trans-critical CO2 systems in commercial refrigeration applications, the Danfoss CTM ejector was named the winner in the award competition’s refrigeration category.

Capable of recovering energy while controlling the high pressure of the trans-critical application, the Danfoss CTM ejector delivers value to the application through improvements in energy efficiency — 20 percent or more are achievable in the warmest ambient conditions. This is accomplished by employing energy recovered from the gas cooler and transferring it to increase the pressure of gas being compressed by parallel compressors, thus reducing overall compressor load.

As a commercially viable solution engineered to overcome energy penalties associated with operating trans-critical CO2 systems in high ambient temperatures, the CTM ejector also eliminates the need for redundant, cascade refrigeration systems — making trans-critical CO2 systems more efficient than HFC systems in any climate zone.

As an Honorable Mention in the program’s green building category, Danfoss Turbocor TG compressors are oil-free, variable speed, magnetic bearing centrifugal compressors that operate with refrigerants that have a low global warming potential.

Designed for air- and water-cooled chillers ranging from 40 to 500+ tons when manifolded and/or used in multiple circuits, the Danfoss Turbocor TG compressor series provides energy efficiency at full- and part-loads in a compact and lightweight footprint. Originally introduced with HFO1234ze, the TG series includes compressor capacities ranging from 40 to 150 tons and also accommodates new refrigerant blends, allowing customers to meet their flammability and capacity requirements while still providing a reduced GWP solution.

As part of the Danfoss Turbocor family, the TG compressor series combines the efficiency, sound, and maintenance benefits of all Turbocor compressors with a future-proof alternative for chiller systems that addresses both energy efficiency and refrigerant regulations and standards. At the 2015 AHR Expo, Danfoss Turbocor VTT series of compressors was given the award competition’s top honors as the Product of the Year.

The annual awards competition honors inventive and original products, systems and technologies showcased at each year’s AHR Expo (International Air-Conditioning, Heating, Refrigerating Exposition) in the categories of: building automation; cooling; green building; heating; indoor air quality; plumbing; refrigeration; software; tools & instruments; and ventilation.

Winners were selected by a panel of third-party ASHRAE member judges who evaluated all award entries based on innovative design, creativity, application, value, and market impact.

Award winners were recognized in a ceremony during the 2017 AHR Expo.
