Sept. 9, 2013: Development of Natural Refrigerant Heat Pump Receives DOE Grant

New Heat Pump Technology Expected to Reduce Energy Consumption by 50 Percent

NASHVILLE, Tenn. — Part of a U.S. Department of Energy (DOE) project to reduce energy bills and greenhouse gas emissions, S-RAM Dynamics has been awarded a grant to help commercialize a new natural refrigerant heat pump.

According to the company, the heat pump will also reduce energy consumption for commercial and industrial customers by more than 50 percent when compared to other common air conditioning and heating systems. The system is being developed in coordination with Purdue University and performance testing will be done at DOE’s Oak Ridge National Laboratory.

“This is a big award for us. Energy efficiency and greenhouse gas emissions are major concerns, and the DOE recognized the potential impact of the new heat pump using our company’s proprietary compressor and expander technology,” said Lee Jestings, S-RAM president.

Assistant Secretary for Energy David Danielson announced the selection of the S-RAM technology as part of the “Next Generation Energy Efficient Buildings Technologies” program. According to Danielson, “Energy efficient technologies — from improved heating and cooling systems to better windows and lighting — provide one of the clearest and most cost-effective opportunities to save consumers money while curbing greenhouse gas emissions.”

“We are excited to be part of testing S-RAM’s technology and to assist them with commercializing this heat pump,” said Dr. Eckhard Groll, the Reilly Professor of Mechanical Engineering at Purdue University. “This technology can eliminate the use of high global warming refrigerants and improve energy efficiency while providing comfortable and productive indoor environments for occupants.”

S-RAM Dynamics holds 47 patents for its variable power conversion technology. For more information, visit www.s-ram.com.
