New Advanced Refrigeration Technology Provides Clean Energy, Low Utility Bills for Supermarkets

Read the full story from U.S. DOE.

Traditional supermarket refrigeration systems found in most U.S. grocery stores require a substantial amount of energy to keep fruits and vegetables fresh year round. An average supermarket consumes nearly 2 million kilowatt hours per year, and refrigeration accounts for nearly half of that. They are also prone to significant refrigerant leakage—from two to four thousand pounds a year—emitting environmentally harmful greenhouse gases into the atmosphere. The most common of these gases are hydrofluorocarbons (HFCs), which are 4,000 times more potent than carbon dioxide.

Oak Ridge National Laboratory (ORNL) and leading refrigeration systems manufacturer Hillphoenix worked together to develop a supermarket refrigeration system that is more environmentally friendly, more energy efficient, and uses less electrical energy. The Second Nature® Advansor System, which hit the market in 2014, reduces greenhouse gas emissions by 78% compared to existing systems and lowers energy consumption by 25%.
