2. Characteristic of Pressure
As shown in Table 2, R32 does not have much difference in vapor pressure at the same refrigerant temperature
comparing to R410A, but comparing to R22, it is higher at 1.6 times more. Thus, the same as in case of R410A, it is
necessary to do installation and service using high-pressure tools and components.
