Figure 2 shows the P-h diagrams of R410A and R32 in comparison. It can be easily seen that the enthalpy difference between the saturation vapor and liquid lines of R32 is always larger than that of R410A, and therefore the latent heat of R32 is higher than that of R410A. The slope of isentropic lines of R32 is also lower than that of R410A, and therefore the compressor power consumption per unit mass flow rate of R32 is typically higher than that of R410A in an identical pressure lift condition.
