Indo R-404A Refrigerant
Indo R-404A is a hydrofluorocarbon (HFC) refrigerant blend designed for use in refrigeration applications. It is commonly used in commercial refrigeration systems, including those for frozen foods, refrigerated trucks, and air conditioning systems.
Specifications
- Chemical Formula: R-404A is a mixture of three gases:
- R-125 (50%) – 1,1,1,2-Tetrafluoroethane
- R-143a (44%) – 1,1,1-Trifluoroethane
- R-134a (6%) – 1,1,1,2-Tetrafluoroethane
- Molecular Weight: 97.6 g/mol (average)
- Boiling Point: −46.5°C (−51.7°F) at 1 atm
- Critical Temperature: 72.1°C (161.8°F)
- Critical Pressure: 4.059 MPa (588.5 psi)
- ODP (Ozone Depletion Potential): 0 (No effect on ozone layer)
- GWP (Global Warming Potential): 3922 (over 100 years)
- Vapor Pressure (at 25°C): 2.5 MPa (362.6 psi)
- Appearance: Colorless, odorless gas
- Flammability: Non-flammable under normal conditions
Applications
- Commercial Refrigeration: Used in supermarket refrigeration, walk-in coolers, and display cases.
- Transport Refrigeration: Commonly used in refrigerated trucks and containers.
- Cold Storage: Widely used in cold storage systems for frozen foods and pharmaceuticals.
- Industrial Refrigeration: Found in large-scale industrial cooling systems.
Environmental Impact
- Global Warming Potential (GWP): R-404A has a high GWP of 3922, contributing significantly to climate change if released into the atmosphere.
- Ozone Depletion Potential (ODP): R-404A has an ODP of 0, meaning it does not affect the ozone layer.
- Phase-out in Future: Due to its high GWP, there are efforts to phase out R-404A in favor of more environmentally friendly refrigerants like R-448A and R-449A.
