Key Applications of R32
R32 (difluoromethane, CH₂F₂) is an eco-friendly refrigerant with zero ozone depletion potential (ODP=0) and a relatively low global warming potential (GWP=675), positioning it as a core solution for the global air conditioning and refrigeration industry .
In the residential air conditioning sector, R32 has emerged as the mainstream choice, offering superior energy efficiency and high volumetric cooling capacity. In China’s household air conditioner market, R32-based models accounted for 78.6% of total production in 2024, further rising to 83.2% between January and September 2025. Leading brands including Midea, Gree, and Haier have all transitioned their mainstream models to R32 formulations . Beyond residential applications, R32 is also widely used in commercial and industrial air conditioning systems, automotive air conditioners, as a key component in blended refrigerants such as R407C and R410A, and as a critical raw material for PVDF production.
Key Safety Precautions
R32 is classified as an A2L (mildly flammable) refrigerant, with a flammability limit in air of 15%–31%. It may ignite or explode when exposed to open flames or electrical sparks . The following precautions should be observed:
No mixing of refrigerants: R32 and R410A have significant differences in operating pressure; mixing can cause system pressure anomalies and compressor failure .
Power-off and leak detection before operation: Disconnect the air conditioner power supply entirely, and use an electronic leak detector or soapy water to inspect all connecting pipelines .
Keep away from ignition sources, ensure ventilation: In case of R32 leakage, ensure the workspace is well-ventilated and free from open flames.
Qualified personnel and proper PPE: Operation should be performed by certified technicians wearing low-temperature-resistant gloves and splash-proof goggles
Proper storage and transportation: Store R32 in a dry, well-ventilated area at ambient temperatures not exceeding 35°C, away from heat and fire sources .
