Comparison of Refrigerant Gas R407c and R134a

ItemR134aR407c
ComponentSingle 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 metalsIn   all refrigeration refrigerants, it has less corrosion to metals and good   stability.Slightly   larger
Damage to the ozone layerThe   global warming potential GWP value is 1600, which is better than R407c.The   global warming potential GWP value is 1980, and R134a is larger.
toxicityClose   to nothingClose   to nothing
FlammabilityNoNO
Affected by temperatureSmallDue   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 applicationlarge   cooling capacity, commercial, screw and centrifugal chillerssmall   cooling capacity, household, small air-cooled chillers
