Core4 Systems is developing a system to more efficiently cool data centers. Core4's promised energy savings comes from reduced compression, achieved in a number of ways. Instead of filtering external air, Core4 claims to use only internal air ¢‚¬" in a method called refrigerant-side economizing ¢‚¬" which attempts to mitigate the filtering costs while cutting compressor energy consumption.Per the company, Core4 also uses outside wet-bulb temperatures ¢‚¬" the temperature at which water begins to evaporate outside ¢‚¬" rather than the higher dry bulb temperature, which aims to allow its gear to continue economizing even on extremely hot, humid days when airside systems can't. Refrigerant-side economizing also cuts down on server and hard drive failures, which contribute to the volume of e-waste shipped to overseas landfills.
EcoDog, Inc. offers energy consumption tools with the aim of helping to reduce homeowners' expenses and lowering demand for electricity.
Hexaformer's technology aims to make it possible to manufacture closed symmetrical delta shaped transformer cores. Per the company, it does this by winding the transformer core instead of stacking sheets of metal. The benefits according to the company of this design to transformers include: a lower load loss, lighter, smaller volume, less vibrations, less noise, smaller electromagnetic stray fields, lower inrush current, and no third harmonic. The same type of technology is also used in the Hexaformer reactors for phase compensation. These cores are also wound to a triangular shape on which three coils are mounted to make the solutions small, yet efficient. The benefits per Hexaformer of this transformer technology include reducing the losses in the electricity grid as well as lowering the cost of operation and maintenance by 5% to 15% compared to traditional transformers.
Starting with automated transit systems (subway, ART system, monorail, people movers, etc.), Clarian has developed technologies to provide real-time optimization of energy consumption using rate control and power modulation technologies that supplement existing safety-critical onboard and wayside ATC controls as well enable presence-awareness in vehicles so that they can operate in unison, rather than autonomously as they do today. These capabilities in turn create broader network energy efficiencies, smoother ride and reduced wear and tear, increased capacity, and reduced rolling stock and power infrastructure requirements.As part of its research and development efforts, Clarian has developed a suite of energy modeling and simulation tools. These tools can be used by transit agencies and/or system operators as part of either the design process or operational configuration to optimize or re-configure existing operations to begin realizing immediate energy cost-savings.
Optimum Energy provides HVAC optimization software solutions. It helps reduce electricity consumption and carbon emissions. The company serves education, healthcare, pharmaceutical, manufacturing, and other industries. It was founded in 2005 and is based in Seattle, Washington.
PowerWorld Corporation offers products and services that make power system analysis and operation ever more powerful and efficient.
