Document Title
A zero GWP heat pump and distribution system for all-electric heating and cooling in California (REVISED)
Document Type
NOE - Notice of Exemption
Document Description
This project will optimize, test and demonstrate a reversible heat pump system that uses near-zero global warming potential (GWP) refrigerants, such as ammonia (NH3) and carbon dioxide (CO2), for multi-family (MF) or small commercial (SMC) applications. These heat pumps will be in the range of 10 to 20 tons of refrigerating capacity. This new heat pump system will increase cost savings derived from reduced piping installations costs. Additional cost savings and emissions reductions result from lower energy requirements due to higher system efficiency.
