What are the advantages and disadvantages of using R-32 as a refrigerant in HVAC systems?

R-32 is a low-global-warming-potential (GWP) refrigerant that offers several advantages, including high efficiency, low energy consumption, and reduced environmental impact. However, it also has some disadvantages, such as being flammable and requiring specialized equipment and training for handling and installation. Additionally, R-32 is not compatible with all system components and materials, which can limit its use in certain applications.
