The Intelligent Discus Technology
October 1, 2007
The melding of Discus compressors into intelligent store design has been one of those next steps forward in supermarket technology. According to Emerson Climate Technologies, Discus compressors came about because “traditional reed compressors will not allow all of the discharge gas to exit, leading to re-expansion volume. In the Discus compressor, re-expansion is virtually zero, providing the higher possible efficiency.”
The Intelligent Store™ Discus was described “as more than a refrigeration compressor with onboard diagnostics that provides real-time intelligence that tells technicians exactly what they need to know.”
When put in the context of an entire store, there is a “single view into the entire network of facilities.” The package includes control and monitoring of a store’s HVACR, lighting, and other systems.
One recent measure of the effectiveness of Discus technology and Intelligent Store came with the announcement that since the first field test in 2003 and product launch in 2005, the company has installed more than 600 Intelligent Store Discus compressors into supermarket refrigeration systems. Since then, they have accumulated 5 million operating hours without a compressor application failure, the company said.
The Intelligent Store Discus compressor offers features that allow customers to experience fewer compressor failures, thereby saving cost, reducing equipment downtime, and avoiding food spoilage, the company said. By integrating several traditional components into one control module, the Intelligent Store Discus compressor requires less wiring and fewer connection points, improving system quality and ensuring installation ease and consistency.
One example of an installation using the technology is Price Chopper, a supermarket chain in the Northeastern United States, which installed its first Intelligent Store Discus compressor in February 2005. “Intelligent Store Discus compressors do most of the thinking for you. The diagnostics on the compressor inform you of system problems, so you can do predictive maintenance and avoid failures,” said Benny Smith, director of maintenance for Price Chopper.
