Emerson Climate Technologies Inc, a business of Emerson, has introduced a new refrigeration system that has the potential to help a supermarket or grocery store reduce its refrigeration-related energy expenses by up to 10 per cent.

Powered by the Copeland Scroll K5 refrigeration compressor, the new system incorporates two important features that deliver significant system efficiency advantages. The first is variable volume ratio technology, which optimises low-condensing performance. The second is enhanced vapour injection capability for maximum capacity at low set points without having to add more or larger compressors.

“Considering the fact that a typical 50,000 sq ft supermarket incurs approximately $20,000 each month in refrigeration-related energy expenses, the annual cost savings per store can reach $20,000-$24,000,” said Mitch Knapke, market manager, food retail. “Large, national grocery chains can realise millions of dollars in refrigeration-related energy savings each year.”

The new Copeland Scroll K5 refrigeration compressor is designed for large refrigeration needs (7.5 to 15 hp) and for use with low to medium temperature applications, in both standalone and parallel systems.

Every Copeland Scroll K5 refrigeration compressor comes equipped with CoreSense technology, which means contractors can easily diagnose compressor issues, either on-site or remotely, reducing system downtime.

The Copeland Scroll   K5 compressor offers the highest energy efficiency available – lowering utility bills and reducing CO2 emissions.  Additionally, its superior reliability and onboard CoreSense Diagnostics prevent unnecessary service calls, reduce technician callbacks and extend compressor life. 

The new technology enables a 5-20 per cent efficiency improvement:  The motor, scroll and bearing design minimises annual energy consumption. The variable volume ratio adjusts the scroll compression ratio for improved low condensing performance. Vapour injection increases system capacity by 50 per cent and efficiency by 20 per cent on average at low temperature rating condition.
