目前全世界有近20亿台空调（AC）用于空间冷却。这些空调大多使用R134a作为工作流体，R134a是一种全球变暖潜能值（GWP）为1300 kg- co2当量的温室气体（GHG）。根据世界环境安全组织的规定，家用空调系统的GWP值不得超过750 kg-CO2-eq。因此，R134a必须在2025年之前逐步淘汰，并需要一种具有相似热力学性能但GWP较低的替代制冷剂。因此，作者在本研究中研究了几种可能的二元/三元制冷剂混合物。在所研究的制冷剂中，R445A、R30A和NPB2（新提出的混合物：8% R152a + 92% R1234yf）每年可减少90-99%的全球变暖影响（超过2亿吨二氧化碳排放当量）。
Nearly two billion air-conditioning (AC) units are currently being used for space cooling worldwide. The majority of these ACs use R134a as the working fluid, a greenhouse gas (GHG) with a global warming potential (GWP) of 1300 kg-CO2-eq. According to the rules set by the world environment safety organizations, the GWP of domestic air-conditioning systems must not exceed 750 kg-CO2-eq. Hence, the R134a must be phased out by 2025, and an alternative refrigerant with similar thermodynamic properties yet low GWP is required. Therefore, the authors have investigated several potential binary/ternary refrigerant blends in this study. Among the studied refrigerants, R445A, R30A, and NPB2(newly proposed blend: 8% R152a + 92% R1234yf) can reduce 90–99% global warming impact (more than 200 million tonnes of CO2emission equivalent) caused by the domestic air-conditioning systems every year.
