Introduction of R245fa Refrigerant

r245fa refrigerant

Refrigerant R-245fa (1,1,1,3,3-Pentafluoropropane, C3H3F5 ) is hydrofluorocarbon (HFC). 

R245fa is a colorless, transparent, and easy-flowing liquid, with volatility, boiling point of 15.3°C, and stable at normal temperature and pressure.

After my country completely eliminated the first-generation blowing agent (fluorocarbon) R11 in 2010, the second-generation blowing agent R141b and cyclopentane became the substitutes for R11 during 2011-2015. It is widely used in refrigerators, freezers and water heaters. field. With the improvement of national environmental protection requirements and energy efficiency standards, R245fa and R365mfc have become the third-generation blowing agents to replace cyclopentane and R141b. Among them, the United States and Japan tend to use R245fa, while the European Union prefers to use R365mfc.

Currently, China is accelerating the phase-out of (hydrochlorofluorocarbons) HCFCs. R245fa belongs to (hydrofluorocarbons) HFCs as a transitional product, but its promotion is not encouraged due to its high GWP value. At the same time, Honeywell and DuPont advocated that HFO (hydrofluorooxyolefin) R1233zd (trifluoropropylene) and R1336mmz (hexafluorobutene) replace R245fa and R365mfc as the fourth-generation blowing agent.

Introduction of R245fa refrigerant

R-245fa refrigerant is used as a third-generation alternative blowing agent to replace CFC and HCFC as a blowing agent for rigid polyurethane (PU) foam. It is mainly used for polyurethane (PU) foaming of refrigerators, cold storages and building boards, and can also be used for refrigerants to replace R-123 and R-22 refrigerants in central air conditioners (chillers).

R245fa refrigerant storage and transportation

The R-245fa refrigerant cylinder is a pressurized container and should be stored away from fire, heat sources, and direct sunlight. Usually stored in a cool, dry, and ventilated warehouse. When handling, it should be lightly loaded and unloaded to prevent damage to accessories such as cylinders and valves.

R245fa refrigerant application

R-245fa can be used as a foaming agent for refrigerators and sheet polyurethane thermal insulation materials. When used as a refrigerant, it is widely used in Organic Rankine Cycle systems (ORC), low temperature waste heat (flue gas waste heat, industrial gas, high temperature fluid, etc.), solar energy, biomass energy, geothermal energy industry, ocean temperature difference, and other power generation systems. Using the Organic Rankine Cycle system can reduce carbon dioxide emissions while increasing the amount of clean energy. Using R245fa as the working fluid can effectively improve the efficiency of the Organic Rankine Cycle system by 5%-8%.

Advantages of R245fa refrigerant

HFC-245fa is a fluorinated hydrocarbon used as a refrigerant to replace R11 and R123 in new centrifugal chillers. The ozone depletion potential (ODP) is 0, and it has little impact on the environment. It is an environmentally friendly refrigerant.
