خلاصه مقاله:
This paper aims to address the challenge of improving the performance of Heat Pumps (HPs) in cold climate condition by applying refrigerant mixtures . Thepotential benefits of implementing R32/CO2 zeotropic refrigerant mixtures in three different residential airsource HPs for cold climates is studied. The casesstudied are: conventional residential HP, HP with variable mixture control system and HP with variable compressor speed. The seasonal performance of aheating system with these air-source HPs, supplemented with an auxiliary electric heater is studied in the cold climate city of Montreal. To thisaim, a detailed screening HP model previously developed is modified and used. The obtained results highlight the potential HP performance improvement of applying refrigerant mixtures .
