Open Case Refrigeration Wastes Tons of Energy

cool flow energy manageOn average, 75 percent of the energy used to operate open case refrigeration is wasted, according to Cool Flow Dynamics; a Sarasota, Fla.-based company that is developing an energy efficiency product for open-case display refrigerators used by food and beverage retailers.

The Florida Institute for the Commercialization of Public Research finalized a funding agreement with Cool Flow to help the company deploy its product.

With technologies licensed from the University of Florida, Cool Flow Dynamics is developing a retrofit “plug and play” device that attaches to the outside of an existing open case refrigerator. Using extremely low power plasma, a wall of fast moving air similar to a waterfall is released over the open area of the unit, creating a separation wall so that neither cold air in the unit, nor the warm air from the outside can penetrate the moving air. Cool Flow Dynamics’ retrofit solution has no moving parts, unlike fans and motors.

Open-case refrigeration has become a global problem and is the largest source of wasted energy in the retail sector in the United States where convenience and grocery store open case refrigeration costs can account for up to 55 percent of the business’ total energy consumption, according to the Institute.

Formed by the Florida Legislature in 2007, the Florida Institute for the Commercialization of Public Research is a non-profit that supports new company creation based on publicly-funded research, and bridges early funding gaps for companies spinning out of Florida-based universities and research institutions.
