Key Properties of R-22
Low Boiling Point
R22 refrigerant boils at about −41.8°F, making it effective for medium to low-temperature cooling applications.
Higher Pressure Operation
Runs at higher pressures compared to older refrigerants like R-12, which requires compatible system parts.
Improved Energy Efficiency
Offers stronger cooling efficiency than many legacy refrigerants, helping systems perform more reliably.
Non-Zero Ozone Depletion
With an ODP value of around 0.055, R22 has an environmental impact that led to its phase-out in new equipment.
Global Warming Potential
R22 carries a GWP of about 1810—still significant, though lower than some alternatives once widely used.
Non-Flammable
Classified as ASHRAE A1, meaning non-flammable and low toxicity when handled properly.
