| Item | R134a | R407c |
| Component | Single working fluid R134a will not affect the effect due to leakage, evaporation or other conditions. | The non-azeotropic mixing working fluid is composed of three working fluids of R32, R125 and R134a mixed with strict quality components of 44%, 52%, and 4%. Due to the different boiling points of the three components of the working fluid, leakage evaporation or other accidents during the use of the unit will affect the percentage of the original working fluid, thus failing to achieve the expected use effect. |
| Corrosion to metals | In all refrigeration refrigerants, it has less corrosion to metals and good stability. | Slightly larger |
| Damage to the ozone layer | The global warming potential GWP value is 1430, which is better than R407c. | The global warming potential GWP value is 1700 |
| toxicity | Close to nothing | Close to nothing |
| Flammability | No | No |
| Affected by temperature | Small | Due to the different boiling points of the three working fluids, the increase in temperature will cause different degrees of evaporation, which will affect the percentage of the original working fluid, which will not achieve the expected use effect. |
| Scope of application | large cooling capacity, commercial, screw and centrifugal chillers | small cooling capacity, household, small air-cooled chillers |
