Refrigerant Gas R32

Refrigerant Gas R32, chemically known as difluoromethane, is a new type of hydrofluorocarbon (HFC) refrigerant. It offers outstanding environmental performance and refrigeration efficiency, making it one of the mainstream new refrigerants replacing R22 and R410A. Its CAS number is 75-10-5, UN number is 3252, and it is classified as a Class 2.2 non-flammable, non-toxic gas under dangerous goods regulations (some standards classify it as A2L, low toxicity and slightly flammable). Product attributes: R32 refrigerant is a colorless, odorless gas with an ODP of 0 and a GWP of 675. Compared to R410A, its GWP is significantly reduced, aligning more closely with global low-carbon environmental trends. It is an optimal refrigerant for achieving the "dual carbon" goals.

Core parameters: At standard atmospheric pressure, R32 has a boiling point of -51.7°C, critical temperature of 78.1°C, critical pressure of 5.78 MPa, saturated vapor pressure of 1.72 MPa at 25°C, purity ≥99.9%, moisture content ≤0.001%, and acidity ≤0.00001%. Functionally, Refrigerant Gas R32 offers advantages including high refrigeration capacity, superior heat transfer efficiency, and low energy consumption. Its Coefficient of Performance (COP) exceeds that of R410A by 5%-10%, significantly reducing operational energy consumption in refrigeration equipment such as air conditioners. Additionally, R32 delivers greater refrigeration capacity per unit mass, enabling reduced refrigerant charge volumes and lower usage costs.

Primary application scenarios include residential air conditioners, commercial central air conditioning systems, heat pump systems, and small commercial refrigeration equipment, making it particularly suitable for manufacturing high-efficiency, energy-saving air conditioners. Regarding customer collaboration cases, we supplied R32 refrigerant to an appliance manufacturer for their production of 8 million high-efficiency, energy-saving air conditioners annually. After adopting the R32 refrigeration system, these units achieved a COP exceeding 4.5, meeting China's Class 1 energy efficiency standards. Compared to R410A-based units, carbon emissions were reduced by 60%. The products successfully obtained EU energy efficiency certification, with exports accounting for 40% of the company's total exports. Additionally, we supplied R32 refrigerant for a heat pump heating project in a northern region. This project utilizes R32 heat pump systems to provide heating for 500 households. The system operates stably even in low-temperature environments of -15°C, delivering high heating efficiency and achieving 35% energy savings compared to traditional heating methods.

The advantages of R32 refrigerant are as follows: First, it offers outstanding environmental performance with an ODP value of 0 and a low GWP value, aligning with global environmental regulations and eliminating long-term phase-out risks. Second, it delivers high refrigeration efficiency, enhancing equipment energy performance and reducing operational energy consumption to meet user demand for energy-saving products. Third, it requires lower charge quantities, minimizing refrigerant mass per unit of cooling capacity and thereby reducing raw material costs and leakage risks. Fourth, it offers strong compatibility, being compatible with core components of existing R410A air conditioners. Replacement can be achieved through optimized system design, facilitating product upgrades for enterprises.
