R-32 is a refrigerant commonly used in air conditioning and refrigeration systems. It is part of the HFC (hydrofluorocarbon) family and is known for its lower global warming potential compared to other refrigerants like R-410A. R-32 is more energy-efficient, which can lead to reduced electricity consumption and lower operating costs. This refrigerant has a high cooling capacity and is easier to recycle, making it a more environmentally friendly option. However, R-32 is classified as mildly flammable, so proper safety measures must be taken during its handling and use in HVAC (heating, ventilation, and air conditioning) systems.
