For the MT, R407f shows higher temperature at the outlet of compressor, from 104 _C to 112 _C, than R404a and R410a, which show similar values, from 90 _C to 98 _C. Furthermore, R410a has higher evaporation and condensation pressures than the other two alternatives. Considering 0 _C as the thermostatic chamber temperature set-point, the R410a evaporating pressure is in the range [5; 6]bar, while the evaporating pressure range for R407f and R404a is [3; 3.5]bar. Considering the LT system, R407f shows higher temperature after vapor compression than R404a, as for MT. The evaporation pressures are comparable, while R407f has a slightly higher condensing pressure than R404a.
