As shown in
Figure
12-33, place the refrigerant in an indoor place with
constant temperature and humidity for 24 hours. Then, use a thermometer to
measure the temperature of the refrigerant tank outer surface and connect a
pressure gauge to the pressure tank to measure the internal pressure. Find the
saturation pressure corresponding to the measured outer surface temperature
from
Table
12-1. If the deviation between the saturation pressure and the
measured internal pressure is greater than 0.2 MPa, the refrigerant does not
meet the requirements and needs to be replaced.
