- W4387496481 abstract "Energy conversion in accordance with environmental protection is becoming one of the dominant factors for the sustainable development of modern society. Most of the present air-conditioning (AC) systems use hydrofluorocarbons (HFCs), which contribute to global warming, as the working fluid. In contrast, natural refrigerants, such as CO2 (carbon dioxide), NH3 (ammonia), R290 (propane) and hydrocarbons (HCs) have a significantly lower climate relevance. Furthermore, R744 (carbon dioxide) is favorable, from the perspective of safety, compared to R290 and R717 (ammonia). In this study, an energetic, environmental, and economic analysis is conducted to evaluate the performance of a residential air-conditioning system using CO2, R410A, and R32 as the working fluids. An assessment is carried out by analyzing the AC systems in temperate and subtropical regions in Europe, in particular Munich, Florence, and Malaga. The load demand of a multi-family house is estimated by the Hourly Analysis Program (HAP). The AC systems and their energy consumption is simulated by Aspen Plus and validated by experimental data. The life cycle assessment is performed using SimaPro software and, additionally, an economic analysis is conducted. The results show that the annual emitted CO2-equivalents of the CO2 air-conditioning system are up to 75.1% lower than those of R410A and R32. However, in case of CO2 as the working fluid, the annual energy efficiency ratio is reduced by between 23.3% and 31.4%, while the life cycle cost increases by up to 55.4% compared to the studied HFC air-conditioning systems. In general, it was concluded that, for countries in the temperate zone, it is a promising way to adopt a CO2 air-conditioning system for space cooling in the near future with the assistance of an electricity price subsidy and CO2 compressor price reduction, while it is not suitable for countries in the subtropical zone, such as Malaga." @default.
