3.1.2.2 Refrigerant Oil

Danfoss 160SZ refrigerant oil is recommended. It can be purchased by Huawei or by the
customer after confirmed by Huawei.
Whether refrigerant oil is needed depends on the length (L) of the single-way piping between
air conditioner indoor and outdoor units.

L ≤ 10 m: Add refrigerant of the standard amount. No refrigerant oil is required.
L > 10 m: In addition to the standard amount of refrigerant, add extra refrigerant and
refrigerant oil.
Liquid pipe: copper pipe (for R410A) external diameter: 5/8 inch; thickness: 1.0 mm;
pressure tolerance range: ≥ 4.5 MPa.
Gas pipe: copper pipe (for R410A) external diameter: 7/8 inch; thickness: 1.2 mm;
pressure tolerance range: ≥ 4.5 MPa.
Thermal insulation foam: thickness ≥ 13 mm.
Oil traps and inverted traps: To ensure the NetCol5000-A reliability, make an oil trap
every 5 m to 6 m along pipes in the vertical direction and make an inverted trap
respectively at the intake vent and exhaust vent of the outdoor unit. Figure 3-2 shows the
specifications for the oil traps and inverted traps.
