Syracuse University will develop a near-range micro-environmental control system transforming the way office buildings are thermally conditioned to improve occupant comfort. The system leverages a high-performance micro-scroll compressor coupled to a phase-change material, which is a substance with a high latent heat of fusion and the capability to store and release large amounts of heat at a constant temperature. This material will store the cooling produced by the compression system at night, releasing it as a cool breeze of air to make occupants more comfortable during the day. When heating is needed, the system will operate as an efficient heat pump, drawing heat from the phase-change material and delivering warm air to the occupant. The micro-scroll compressor is smaller than any of its type, minimizing the amount of power needed. The use of this micro-environmental control system, along with expanding the set-point range could save more than 15% of the energy used for heating and cooling, while maintaining occupant comfort.
If successful, DELTA technology could increase energy efficiency, reduce emissions produced by powering traditional HVAC systems, and enable more sustainable heating and cooling architectures for energy-efficient building design.
The innovations developed under the DELTA program have the potential to increase energy efficiency, improve overall building performance, and reduce HVAC energy consumption by at least 15%.
The heating and cooling of buildings generates about 13% of the U.S. domestic greenhouse gas emissions. Through improved utilization of energy produced by fossil fuels with full adoption DELTA can reduce these emission by 2%.
DELTA program innovations can help U.S. businesses eventually reduce reliance on tightly controlled building environments, thus enabling radical and sustainable architecture in next generation energy efficient building designs.
