Danfoss is proud to announce that their DSG compressor has been named the winner in the Cooling category of the 2024 AHR Expo Innovation Awards.
The annual awards competition honors the most inventive and original products, systems, and technologies that will be showcased at this coming January’s International Air-Conditioning, Heating, Refrigerating Exposition (AHR Expo) in the categories of building automation; cooling; sustainable solutions; heating; indoor air quality; plumbing; refrigeration; software; tools and instruments; and ventilation.
Features of DSG compressor
The DSG features an innovative design to enable a smooth transition to low-pressure, low-GWP refrigerants. Specifically designed for low-pressure refrigerants such as R1234ze with low global warming potential, it provides chiller systems with a wide range of compressor capacities to support unit design requirements.
Supported applications include but are not limited to:
- 100-600 kW hydronic systems–air-to-water and water-to-water units with both single and dual refrigeration circuits
- Comfort cooling air to water chillers
- Comfort cooling and reversible water to water chillers
- IT cooling air to water and water to water chillers
- Process air to water and water to water chillers with positive temperatures
- Chillers for medium temperature small/medium cold rooms
Operation and energy efficiency
DSG platform is devised so that the physical compressor size is almost the same as with the R410A
Single compressors are available from 20 to 40 tons of refrigeration and larger capacities are available in manifolded configurations to offer enhanced system design flexibility. The DSG platform has been designed so that the physical compressor size is virtually the same as with R410A.
To achieve this, the entire compressor has been newly designed internally from the ground up to take advantage of all the available area inside the compressor shell. The DSG also has an optimized intermediate discharge valve inside the compressor to further enhance part load capacity operation and energy efficiency.
AHR Expo Innovation Awards program
“The DSG enables a smooth transition to low-GWP refrigerants without a major increase in compressor size,” said Nick Mislak, the Regional Segment Marketing Director for HVAC at Danfoss, adding “Its optimized design makes it one of the most innovative compressors on the market today, and we are proud to be recognized with this award."
Winners of the AHR Expo Innovation Awards program are selected by a panel of third-party ASHRAE member judges who evaluate all award entries based on innovative design, creativity, application, value and market impact. This year’s award winners will be recognized in a formal ceremony during the 2024 AHR Expo, which takes place January 22-24 in Chicago, USA.
