R290 Refrigerant (Propane)
R290, also known as Propane, is a natural hydrocarbon refrigerant with a chemical formula of C3H8. It is characterized by a very low environmental impact due to its minimal Global Warming Potential (GWP) of 3, making it a preferred alternative to traditional refrigerants. However, it is highly flammable and classified as a Class A3 refrigerant, requiring careful handling and specific safety measures when used in refrigeration systems.
Key Specifications
- Chemical Name: Propane
- Chemical Formula: C3H8
- GWP (Global Warming Potential): 3
- ODP (Ozone Depletion Potential): 0
- Safety Classification: A3 (Highly Flammable)
Key Advantages
- Low Environmental Impact: Has a minimal effect on global warming.
- Good Thermodynamic Properties: Enhances system efficiency and performance.
- Energy Efficient: Helps reduce energy consumption.
Important Considerations
- Flammability: Due to its high flammability, R290 requires special installation and maintenance procedures, including proper ventilation and leak detection systems.
- Charge Limits: Regulations often limit the amount of R290 that can be charged in a system depending on the application and installation location.
- Trained Technicians: Only properly trained and certified technicians should handle and service equipment using R290.
