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.

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.

2025年2月15日 · R32 refrigerant, also known as difluoromethane, is a hydrofluorocarbon (HFC) commonly used in air conditioning systems. It is gaining popularity due to its lower global warming potential compared to older refrigerants like R410A. The composition of R32 allows for efficient heat transfer, making it an effective choice for modern cooling systems.

2025年1月15日 · R32 is up to 12% more efficient than 410A. Daikin’s test labs for inverter-driven compressors used in rooftop units and water-cooled chillers found that R32 surpasses 410A in both full-load and partial-load efficiency ratings drive the high-efficiency rating.

An international standard equation of state for difluoromethane (R-32) for temperatures from the triple point at 136.34 K to 435 K and pressures up to 70 MPa. J. Phys. Chem. Ref. Data, 26 (6):1273–1328, 1997. doi:10.1063/1.556002. Marcia L. Huber, Arno Laesecke, and Richard A. …

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.

2022年1月4日 · R32 refrigerant is a relatively new innovation in AC technology developed as an alternative to the refrigerants used today. It is a hydrofluorocarbon, or HFC, air conditioning manufacturers are adopting as a safe, efficient, and environmentally friendly refrigerant option.

As a pure, single-component refrigerant, R-32 can be topped up and recharged in the field, in both liquid and gas phases, without changes in composition. It is easy to clean and reuse on-site, and easy to reclaim off-site with a simple cleaning process. Up to 12% more efficient than comparable R-410A systems.

R32, or Difluoromethane if you want to get technical, is a colorless gas that’s really good at transferring heat. In an AC system, R32 absorbs heat from the indoor air and releases it outside, leaving you with a nice, cool room.
