But, at the same condensing temperature and the same evaporating temperature, the discharge temperature of R404A is obviously lower than that of R502. The difference is about 3-12 . The lower the evaporating temperature is and the higher the condensing temperature is, the greater the difference will be.

The Professor: Condensing Temperatures and Condensing Splits ...When talking about air-cooled condensers, the temperature difference between the ambient and the condensing temperature is often referred to as the condenser split. For example, if the condensing temperature is 110˚F and the ambient is 80˚, the condenser split would be 30˚ (110–80).

R-410A – Why is it such an Interesting Refrigerant FluidAbove this temperature (equivalent to a condensing temperature of around 60°C) the refrigeration capacity of the R-410A system starts to fall off more rapidly. At this temperature the relative drop in capacity exhibited by R-410A systems is around 10% greater than that of an R-22 system. These results are summarised in Figure 1 and Figure 2:

On condensing humidity (dew point) - AnTherm HelpFor that reason the term of "condensing humidity" is introduced when assessing surface temperatures in the context of condensation risk. The "condensing humidity" is the value of relative air humidity at which, when it is exceeded, the vapour condensation will occur on the surface having some specific temperature.
The Influence Of The Temperature Of Condensation ... - Ref wikiTherefore, the actual volume of consumption of steam displaced by the compressor is reduced. Therefore, even though the density of the vapor coming from the compressor is the same on all of the condensing temperature, the actual mass flow of refrigerant released compressor decreases as the volumetric efficiency decreases.
