Global Warming Potential (GWP) has proven to be just as critical in determining a possible coolant in recent years as Ozone Depletion Potential (ODP). By lowering the refrigerant charge and enhancing the coolant containment systems, R152A emissions are now aggressively reduced. The option to use the R152A device must be discussed due to concerns about its global warming potential. Disperse the specified quantities of nanoparticles in the compressor oil using a magnetic stirrer for two hours, and then ultrasonic dissolve for four hours to prepare the necessary volume fractions. The experiments showed a performance improvement using CuOs with 0.5% volume fractions with a base refrigerant such as R152A. Experimental results from three different nanoparticles, such as CuO, ZnO and Al₂O₃, indicate strong miscibility of the nano-CuO lubricant and an increase in lubricity oil to two nanoparticles.

近年来，全球变暖潜能值 (GWP) 已被证明与臭氧消耗潜能值 (ODP) 一样，对于确定可能的冷却剂至关重要。通过降低制冷剂充注量和增强冷却剂密封系统，R152A 排放量现已大幅减少。由于担心 R152A 设备的全球变暖潜力，必须讨论使用 R152A 设备的选择。使用磁力搅拌器将指定数量的纳米粒子分散在压缩机油中两个小时，然后超声溶解四个小时以制备必要的体积分数。实验表明，使用体积分数为 0.5% 的 CuO 以及 R152A 等基础制冷剂可提高性能。三种不同纳米颗粒（例如CuO、ZnO和Al ₂ O ₃）的实验结果表明，纳米CuO润滑剂具有很强的混溶性，并且两种纳米颗粒的润滑油性能有所增加。
