2017年11月1日 · Viscosity measurements were performed with a falling cylinder viscometer on difluoromethane (R32) and the refrigerant blend R410A (R32 + R125 with 50% by mass) at the temperatures 313.15 K, 348.15 K, and 393.15 K with pressures of 350 MPa.

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 …

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。

2017年8月1日 · Viscosity measurements were performed with a falling cylinder viscometer on difluoromethane (R32) and the refrigerant blend R410A (R32+R125 with 50 % by mass) at the temperatures 313.15 K, 348.15 K, and 393.15 K with pressures to 350 MPa.

2024年7月9日 · R32是一种单 一成 分的HFC制冷剂，具有较低的GWP值，约为R410A的一半。 它在制冷效率上与R410A相当，但对环境的影响较小。 R32在一定条件下可燃，因此在设计和安装使用R32的系统时，必须采取额外的防火措施，确保安全操作。

2017年8月1日 · Viscosity measurements were performed with a falling cylinder viscometer on difluoromethane (R32) and the refrigerant blend R410A (R32 + R125 with 50% by mass) at the temperatures 313.15 K,...

2022年9月22日 · The results reveal that the optimum charge for R32 is 350 g that represents only 70% of the refrigerant amount for R410a. R32 performs better than R410a for both lubricants mixture. The R32-POE combination shows the best performance with …

1998年1月1日 · A comparison is made with experimental data for pure R32, R 125 and R 134a, and for R32 + R 134a and R 125 + R32 binary mixtures. The equation of state yields a good representation of thermodynamic property data in the range of temperatures 0.8 Tc (x) ≤ T ≤ 1.5 Tc (x) and densities 0.35 ϱc (x) ≤ ϱ ≤ 1.65 ϱc (x).

R32 is a high-pressure liquefied gas. as mentioned in 1-2, R32 is classified as flam-mable under international standards (but under Japan‘s High Pressure gas safety act, it is not classified as a flammable gas). to handle R32 safely, please observe applicable laws and regulations.
