Abstract: Achieving near-zero emissions by 2050 requires residential air-conditioning systems to integrate renewable energy sources, aligning with energy community principles. Additionally, the forthcoming F-Gas regulation will phase out fluorinated gases in domestic heat-pumps, promoting natural refrigerants like propane. However, heat pump performances may degrade up to 50 % overtime due to undetected soft faults, such as refrigerant leakage. These aspects make the optimization of future small-scale heat pumps coupled with renewables challenging, since optimal total cost and environmental impact solutions may diverge.
