What chemical characteristic of R32 makes it preferable for certain applications?

R32 is favored in various applications primarily due to its low global warming potential (GWP). This characteristic is particularly significant in the context of environmental regulations and climate change initiatives. Low GWP means that when R32 is released into the atmosphere, it has a reduced impact on global warming compared to many other refrigerants. As countries and organizations strive to mitigate the effects of climate change, using refrigerants with lower GWP is increasingly becoming a requirement or preference for new systems and technologies.

Additionally, R32 is often used in air conditioning systems and heat pumps because its performance efficiency allows for energy savings, further supporting its sustainable use. The focus on reducing emissions and the environmental impact of refrigerants makes the low GWP of R32 a critical reason for its preference in modern applications. In contrast, while thermal conductivity, flammability, and cost are important factors in refrigerant selection, the significance of GWP aligns closely with global efforts to create greener and more efficient technologies.
