2018年12月10日 · R-32 along with R-125 are some of the most versatile refrigerants used today. While we are used to using R-32 as a blend it is also seeing a rise of usage in residential and commercial air conditioners. This rise started in the eastern countries like Japan, Korea, India, and now Australia.

R32制冷剂无色、无味，并具有轻微燃烧特性（A2级别），其沸点在常压下为-51.6ºC。 在空气中，其燃烧极限范围为14%~31%（体积比）。 常温条件下，HFC-32结构稳定，不易分解。 然而，当遇到明火或高温时，它会分解为HF、碳酰氟等物质，其引燃温度为647.8℃。 因此，使用R32制冷剂的设备必须进行抽真空操作，并严格禁止明火接触。 此外，R32制冷剂具有溶于油、难溶于水的特性。 其破坏臭氧潜能值ODP为0，全球变暖系数值GWP为670。 相比R22，R32的 …

R-32 is the most balanced refrigerant in terms of environmental impact, energy efficiency, safety, and cost-effectiveness. Refrigerant is a medium for conveying heat. Air conditioners transfer heat while circulating refrigerant between the indoor and outdoor units.

2020年10月20日 · R-32, also known as HFC-32, is an organic hydrofluorocarbon compound with the formula CH₂F₂. It’s a colorless odorless, mildly flammable gas which is insoluble in water. Some of its properties are contained in the table below.

Both R-32 and R-454B are classified as A2Ls and meet the less than 750 GWP requirement in published CARB regulations and granted EPA petitions. Experts measure Life Cycle Climate Performance (LCCP) to understand refrigerant impacts to the environment.

2024年9月2日 · r32制冷剂，化学名为二氟甲烷，分子式为ch2f2，是一种被广泛应用在空调和其他制冷设备中的制冷剂。 无色、无味、A2级燃烧性的制冷剂，它与R410A性能相近，但拥有零臭氧损耗（ODP=0）和较低全球变暖潜能（GWP=675），优于R410A和R22，主要特点如下：

r32基本性能： 二氟甲烷，分子式：ch2f2。 物理性质：为无色、无味、轻微燃烧（a2级别）。冷媒r410a是无毒，不可燃（a1级别）不爆炸、无毒、可燃，但仍然是安全的制冷剂。 r32的热力学性能与r410a相近。 r22gwp值675。 r32与r410a性能对比

2020年11月12日 · We found in tests of a Daikin inverter compressor rooftop unit with identical hardware, the use of R-32 improved IEER at nominal capacity by 8% as compared to R-410A and 11% as compared to R-454B.

2025年1月15日 · R32 is the future of refrigeration, but why is it the right choice to replace R410A? R-32 is a non-proprietary commodity used in over 130 countries by over 50 OEMs & installed in 230+ million systems worldwide.

R32 refrigerant, or difluoromethane, is a hydrofluorocarbon (HFC) primarily used in air conditioning and heat pump systems and stands out due to its efficiency and reduced environmental impact. Its classification as a single-component refrigerant means it is easier to handle and charge than blends requiring precise ratios for the best performance.
