Precautions for New Refrigerant (R-410A)
Precautions for New Refrigerant (R-410A)
295
2
Temperature scale indicates the relationship between pressure and temperature in gas
saturated state.
Differences
2
Change in pressure
2
Change in service port diameter
7. Charge hose for R-410A
Specifications
2
Working pressure 5.08 MPa (51.8 kg/cm
2
)
2
Rupture pressure 25.4 MPa (259 kg/cm
2
)
2
Available with and without hand-operate valve that prevents refrigerant from outflow.
Differences
2
Pressure proof hose
2
Change in service port diameter
2
Use of nylon coated material for HFC resistance
8. Charging cylinder
Specifications
2
Use weigher for refrigerant charge listed below to charge directly from refrigerant cylinder.
Differences
2
The cylinder can not be used for mixed refrigerant since mixing ratio is changed during
charging.
When R-410A is charged in liquid state using charging cylinder, foaming phenomenon is
generated inside charging cylinder.
(Hose with ball valve)
Can not be used
