46 General Information
<*Non-azeotropic refrigerants or Quasi-azeotropic refrigerants>
When a refrigerant is a mixture of two or more types with different evaporation temperature, it is
called a non-azeotropic refrigerant. If all refrigerant components evaporate at the same
temperature, the mixture is called an azeotropic refrigerant.
If a non-azeotropic refrigerant is charged into equipment in the gaseous state, the refrigerant
components that evaporate sooner than others enter the equipment, and the refrigerant that
evaporate after others remain in the refrigerant cylinder.
* Quasi-azeotropic mixture refrigerant: mixture of two or more refrigerants having similar boiling
points.
Caution items
The following devices designed for R-22 cannot be used to charge the new refrigerants. Be sure
to use the devices specifically designed for the new refrigerants.
1. Charging cylinder...(Pressure resisting specification is different.)
2. Gauge manifold (including hose)...(same as above)
