1.4 Refrigerant Oil
To improve the reliability, the specified designed premium quality refrigerant oil is used in the compressor.
The refrigerant oil containing foam suppressor has the excellent thermal stability and high durability for
overload conditions.
1.4.1 Oil Type
Each type of refrigerant oil is specially designed for certain types of refrigerant and operating conditions, if
additional oil charge is added in the field, Only specified oil should be used.
Table 1-2 Type of Oil
1.4.2 Functions of Refrigerant Oil
1) Lubricate the moving parts to reduce mechanical friction.
2) Absorb the heat generated by mechanical friction .
3) Prevent refrigerant leakage at sealing surface.
4) Rust proof.
1.5 Motor Type
Panasonic scroll compressors can be applied under variable types of power sources, the motor type is shown
in Table 1-3.
