3.1.2.2 Refrigerant Oil
The recommended refrigerant oil is Danfoss 160SZ. You can purchase it from
Huawei, or purchase it by yourself after being
conrmed by Huawei.
If the low-temperature component is connected, additional refrigerant oil. If not, ignore the
refrigerant oil.
3.1.2.3 Pipe Components
Pipe components are optional and include:
● 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
specications for the oil traps and inverted traps.
