As the world shifts to greener refrigerants, R290 (propane) has become a popular choice due to its low environmental impact and excellent thermodynamic properties. In this article, we will explore R290 from various key aspects, such as energy efficiency, operating temperature range, environmental regulations, market trends, and so on, to help you figure out why it is emerging as a popular choice for heat pump systems.
What is R290?
R290 refrigerant, also known as propane, is a natural refrigerant with a significantly lower global warming potential (GWP) of 3, making it an environmental friendly alternative for hydrofluorocarbon (HFC) refrigerants. Its low environmental impact aligns with sustainability goals and appeals to consumers who prioritize long-term eco-friendly practices, making R290 a more environmentally friendly refrigerant option for heat pumps.
The advantages of the R290 air-to-water heat pump
1. Higher COP, Higher Efficiency
Due to its superior latent heat of evaporation and compression characteristics, R290 enables heat pump systems to achieve a higher COP under specific heat exchange conditions. This property allows R290 to provide excellent heat transfer efficiency at relatively low compression ratios, reducing energy loss.
In addition, R290 has a higher thermal conductivity than many synthetic refrigerants, which means it transfers heat faster in evaporators and condensers, transferring heat from one side to the other more efficiently, improving overall system efficiency.

2. Improved Performance in Various Climates
R290 performs well across a wide temperature range, demonstrating strong adaptability. It can efficiently maintain high system performance in both extremely cold and moderate environments, making it especially suitable for air-source heat pumps operating under variable conditions.
3. Excellent Low-Temp Start-Up Performance
R290 exhibits excellent low-temperature start-up performance, without additional heating energy-saving equipment during compressor start-up, which is vital for low-temperature heating systems. Reduced complexity and energy demand of the start-up process contribute to the overall durability and cost-effectiveness of systems.

4. Greater System Compatibility
Many existing heat pump systems can be upgraded to utilize R290 as a refrigerant through relatively straightforward design adjustments. These typically involve several critical enhancements including improving sealing, preventing leakage, and incorporating explosion-proof electrical components to ensure the safe and efficient operation of the system.
5. Fewer Failure and Maintenance Cost
Low compression ratio: R290 has a lower compression ratio, which means it requires less energy during compression, making it easier for the compressor to work, helping to reduce mechanical wear and energy consumption.
Lower vaporization temperature: R290 has a low boiling point (-42°C), making it particularly efficient under partial loads. This helps reduce compressor start-up frequency and energy consumption, which means fewer failures and lower operating costs.
6. Environmental Benefits
R290 has an extremely low GWP of just 3, making it far more environmentally friendly than many synthetic refrigerants, such as R404A, which has a GWP of nearly 4,000. This low GWP means that R290 contributes minimally to climate change, aligning with global efforts to reduce greenhouse gas emissions and comply with regulations like the Kigali Amendment aimed at phasing down high-GWP refrigerants.
7. Compliance with Environmental Regulations
The latest F-gas regulation, known as Regulation (EU) 2024/573, enacted on February 7, 2024, establishes updated measures to achieve more than 80% reduction in HFCs by 2030, with a complete phase-out planned by 2050, and promotes alternatives like R290 (propane) to reduce greenhouse gas emissions. More and more countries and regions have also introduced relevant policies to encourage the use of low-GWP alternative refrigerants, thereby promoting the application of R290 heat pumps.
The Promising Future of R290
According to the International Institute of Refrigeration (IIR), the global demand for environmentally friendly refrigerants will grow significantly in the next few years. It is expected that by 2025, the market share of low-GWP refrigerants will account for more than 50% of the global refrigerant market, and R290, as an important representative, will become the mainstream refrigerant due to its low GWP and compliance with environmental standards.
