Various Freon in walk-in cooler (2)

Various Freon in walk-in cooler The chemical formula of refrigerant R22 in walk-in cooler is CHF2Cl, the standard boiling point of R22 is -40.8℃, and the freezing temperature is -160°C. R22 is non-flammable, non-explosive, colorless, odorless, and slightly more toxic than R12. The solubility of water in R22 liquid is slightly greater than that of R12, but ice plugging will also occur when the wa...
