LOC-GFO-19-301-1 A zero GWP heat pump and distribution system for all-electric heating and cooling in California

Develop, test and demonstrate an advanced zero GWP space conditioning system for multi-family or small commercial applications that is based on a reversible ammonia (NH3) heat pump with carbon dioxide (CO2) distribution, for space heating and cooling applications. A prototype of this technology, delivering space cooling only, was successfully tested at the EPRI lab in Knoxville in 2018-2019. The proposed project, will extend the technology to space heating, optimize the performance of the system, and  develop a roadmap for its commercial development. SDGE ($200K), TVA ($40K), Southern Co ($40K) will be providing financial cost share.
