R32 refrigerant, officially known as Difluoromethane (CH₂F₂), is a modern HFC refrigerant widely used in high-efficiency HVAC systems due to its strong cooling performance and lower environmental impact. Compared to older refrigerants like R410A, R32 delivers faster cooling, higher energy efficiency, and requires a lower refrigerant charge.
In typical HVAC operation, R32 gas pressure ranges from approximately 118–130 psi on the suction side and 350–400 psi on the discharge side, though actual values depend on ambient temperature and system design.
R32 has a GWP of around 675, which is significantly lower than R410A (GWP 2088), and an ODP of 0, making it more environmentally sustainable. It is classified as ASHRAE A2L, meaning low toxicity and mildly flammable, so it must be handled by trained professionals.
Common HVAC applications include split ACs, VRF systems, heat pumps, and inverter-based air conditioners, where its higher volumetric cooling capacity improves system efficiency.
