Desighed pressure of R410A refrigerant
< Pressure Temp >
Relation between R410A condensing temperature and saturated pressure.
< Temp Pressure >
Advantage
Disadvantage
Suitable for
R410A
higher system
performance
Near-Azeotropic
refrigerant
1.6 times higher
(difficult to design against
pressure resistance)
Small Air-Conditioners
pressure than R22
R407C
similar pressure as R22
(possible to design
large equipment)
Zeotropic refrigerant
(handle with care)
Large Air-Conditioners
