ASHRAE ST-16-006

English -- Evaluation of Refrigerant Mixtures in Three Different Cold-Climate Residential Air-Source Heat Pumps

Organization:
ASHRAE - American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc.
Year: 2016

Abstract: Scope: This paper addresses the challenge of improving the performance of heat pumps (HPs) in cold-climate conditions by applying refrigerant mixtures. The potential benefits of implementing R-32/CO2 zeotropic refrigerant mixtures in three different residential air-sourceHPsfor cold climates are studied.ThecasesconsideredareconventionalresidentialHP, HPwith a variable mixture control system, andHPwith a variable compressor speed.The seasonal performance of a heating system with these air-source HPs, supplemented with an auxiliary electric heater, is studied in the cold-climate city of Montreal, Canada. To this aim, a detailed screeningHPmodel previously developed is modified and used. The obtained results highlight the potentialHPperformanceimprovementof applying refrigerant mixtures.
