从生命周期(LC)的角度来看,随着未来汽车保有量的增加,移动的空调(MAC)将成为中国温室气体(GHG)的潜在排放源。MAC-GHG-LCA模型用于计算汽车空调系统的LC GHG排放量,包括整个寿命周期内的制冷剂泄漏(直接排放)和汽车空调系统生产和运行中的能源使用造成的排放(间接排放)。在空调系统中使用R152 a和R1234 yf作为替代制冷剂可以分别减少22-32%和17- 29%的LC GHG排放。其温室气体减排效益主要来自其较低的全球变暖潜值(GWP),尽管其间接排放量仅略低于甚至高于R134 a。使用R744可以在2050年减少排放,但在2020年将增加20%。在仅采用R134 a制冷剂的情况下,2050年中国整个轻型汽车(LDV)车队的MAC系统的LC GHG排放总量将为1.59亿吨CO2当量,约为2015年的3倍。研究发现,低全球升温潜能值的替代制冷剂可以有效地减少汽车空调系统的LC温室气体排放。电动汽车(EV)从传统的冷却和加热技术向先进的热泵技术的转变可以减少MAC系统运行中的电力使用,并减少EV中MAC系统的LC GHG排放。
Mobile air conditioning (MAC) is potentially a huge source of greenhouse gas (GHG) emissions in China from a life cycle (LC) perspective as the vehicle population increases in the future. The MAC-GHG-LCA model is developed to calculate LC GHG emissions from MAC systems, covering life-span refrigerant leakage (direct emissions) and emissions caused by energy use in MAC system production and operation (indirect emissions). Using R152a and R1234yf as alternative refrigerants instead of R134a in MAC systems can decrease LC GHG emissions by 22–32% and 17–29%, respectively. Their GHG reduction benefits mainly result from their lower global warming potential (GWP) values though the indirect emissions are only slight lower or even higher than R134a. Using R744 can offer reduction in 2050 though it will cause an increase of 20% in 2020. Total LC GHG emissions from MAC systems of the whole light duty vehicle (LDV) fleet in China will be 159 million tonnes of CO2-equivalent in 2050 in the scenario where R134a will be the only refrigerant adopted, about 3 times that in 2015. It is found that alternative low-GWP refrigerants can help reduce LC GHG emissions from MAC systems effectively. The shift from conventional cooling and heating technology to advanced heat pump technology in electric vehicles (EVs) can reduce electricity use in MAC system operation and reduce LC GHG emissions from the MAC systems in EVs.
