JFE Engineering America

JFE Engineering is the comprehensive engineering arm of the JFE Group, designing and building energy and environmental systems, steel structures and industrial machinery and systems. The company recently developed a revolutionary energy-efficiency air-conditioning technology in collaboration with the New Energy and Industrial Technology Development Organization (NEDO). The cooling medium at the heart of the new system, clathrate hydrate slurry (CHS), has a thermal density in the temperature range of 7-8 degrees Celsius two to three times greater than the chilled water used in air-conditioning, can store latent heat, and also boasts superior fluidity. CHS Thermal Energy Storage air-conditioning systems are contributing to the advance of the energy-efficiency business by cutting costs in industries with major cooling energy consumption and load-leveling at power companies.
