R32 is a refrigerant that is gaining popularity as a replacement for older refrigerants like R22 and R410A. It is a single-component refrigerant that belongs to the family of hydrofluorocarbons (HFCs). R32 is known for its lower Global Warming Potential (GWP) compared to R410A, making it a more environmentally friendly option for air conditioning and refrigeration systems. It is highly efficient, and its low GWP makes it a preferred choice for modern HVAC systems, especially in residential and commercial applications.
