多种制冷剂R22、R410a、R32的温度压力特性概览及估算方法 - 知乎
这主要是因为与R22相比,R32制冷剂在减少CO2(二氧化碳)排放方面具有显著优势,减排比例高达77.6%,而R410A的减排比例为2.5%。 给大家推出的是制冷剂的温度压力,方便大家在检修、制冷系统分析的时候查询蒸发冷凝温度。 先给大家普及一些简单的估算方法:如下: 冷凝温度=工况温度(空气温度/水温)+(8~18)℃.
制冷剂:R32 - 知乎 - 知乎专栏
r32与r410a热力性能非常接近,与r22相比co2减排比例可达77.6%,(而r410a减排co2为2.5%)。 根据摩尔质量大体上与填充量成正比,相对填充量70%左右。 安全特性方面, R32为无毒可燃A2。

格力等品牌为什么大多都选择 R32 制冷剂? - 知乎
R410A是由R32/R125,质量组成50%/50%组成的近共沸 混合 工质,具有无毒、不可燃、化学性能稳定、ODP为零等优点。 这两种冷媒在制热能力、排气温度及运行范围比较相似,所以可以替代R22应用于热泵系统。 但是,R410A的工作压力比较高,容积制冷量又远远高于R22,所以必须重新设计压缩机,两器,相应的制造工艺和设备也得改进。 简单的说,厂家如果生产使用R410A冷媒的空调,物料成本会变低,因为可以少用铜! 前提是把生产线改了,销售规模够大,就能赚 …
R-32 is actively promoted and adopted by multiple OEMs of rooftops, chillers, window AC, mini-splits and VRV/VRF equipment worldwide. Major mini-split OEMs are expected to bring their R-32 designs into NA before 2025. Daikin contractors have been installing commercially available R-32 mini-splits since 2021 in the US.
