Use high-quality brands such as DuPont, Daikin, or Honeywell.
Contact the refrigerant producer to confirm the refrigerant authenticity.
Check the refrigerant by following the steps shown in
indoors at a constant temperature and humidity for 24 hours. Use a thermometer to
measure the external surface temperature of the refrigerant container, and connect a
pressure gauge to the container to measure its internal pressure. Determine the saturation
pressure that corresponds to the measured external surface temperature according to
Table 3-7 and calculate the deviation from the measured internal pressure. If the
deviation is more than 0.2 MPa, the refrigerant is not qualified and should be replaced.
