Refrigerant R-32 (Difluoromethane) – High Efficiency, Low GWP HVAC Refrigerant
Refrigerant R-32 is a next-generation HFC (hydrofluorocarbon) refrigerant widely used in residential and commercial air conditioning systems. Engineered for superior energy efficiency and environmental responsibility, R-32 offers an excellent balance between performance and sustainability, making it a preferred alternative to traditional refrigerants like R-410A.
Key Features and Benefits of R-32 Refrigerant
-
High Energy Efficiency – Delivers faster cooling and heating performance, helping reduce power consumption and lower operating costs.
-
Lower Global Warming Potential (GWP) – With a GWP of 675, R-32 has significantly less environmental impact compared to R-410A (GWP 2088), supporting compliance with modern environmental standards and regulations.
-
Optimized Heat Transfer – Offers superior thermodynamic properties for stable and consistent system performance.
-
Single-Component Refrigerant – Unlike blends, R-32 is a pure refrigerant, making it easier to recover, recycle, and reuse.
-
Reduced Refrigerant Charge – Requires up to 30% less refrigerant volume than R-410A for the same cooling capacity.
-
Widespread Compatibility – Approved for use in many new high-efficiency HVAC units and heat pumps designed to meet stricter environmental policies.
