R1270是天然制冷剂,具有制冷量大、COP高的优点。环保性能(臭氧消耗潜能值为0,温室效应潜能值较低)和基本热物理性质较好(单位质量制冷量和单位容积制冷量大于R22,排气温度低于R22,气化潜热及导热系数均大于R22),并且一些基本热物理性质(饱和蒸汽压)与R22相近。具有优良的热力学性质和较好的系统循环性能,是R22极有潜力的纯质替代物。在相同条件下,R1270和R22的系统制冷量基本相同,与R22制冷系统相比,R1270的能效比提高6.5%,充灌量下降了51%,压缩比下降27%。在满足制冷量的前提下,通过优化蒸发器,把蒸发器的管径从7mm变为5mm,并减少U型管数,改变流路布置,进行仅改变蒸发器的R1270样机试验,结果表明:R1270和R22的系统制冷量基本相同,R1270制冷系统的能效比为3.31,与R22制冷系统相比,能效比提高12.6%,充灌量下降了55%。
