Title: Development of Heat Pump System Models (Space Heating) for HFO Blends

Abstract

We recently published numerous heat pump system models at the HPDM website, in the category of “Space Heating”. The published system configurations include single-stage heat pumps using TXV for expansion or a short-tube fixed-orifice coupled with a suction line accumulator, a two-stage heat pump system putting two compressors in series, single state heat pump using two parallel compressors (tandem), vapor injection systems with a vapor injection compressor coupled with an intermediate economizer or a flash tank. These configurations should cover all the residential heat pump products on the market. Additionally, To accelerate the refrigerant transition and make thousands of existing compressor maps reusable by the new refrigerants, ORNL created a mathematical approach to scale typical vapor injection compressor maps, developed from one baseline refrigerant to be used by the new HFO refrigerants/blends.
