Refrigerant piping material
▪ Piping material: phosphoric acid deoxidised seamless copper
▪ Flare connections: Only use annealed material.
▪ Piping temper grade and thickness:
Outer diameter (Ø) Temper grade Thickness (t)
(a)
6.4mm (1/4")
9.5mm (3/8")
12.7mm (1/2")
Annealed (O) ≥0.8mm

Depending on the applicable legislation and the maximum working pressure of the unit
(see "PS High" on the unit name plate), larger piping thickness might be required.
7.1.2 Refrigerant piping insulation
▪ Use polyethylene foam as insulation material:
- with a heat transfer rate between 0.041 and 0.052 W/mK (0.035 and
0.045kcal/mh°C)
- with a heat resistance of at least 120°C
▪ Insulation thickness:

Insulation thickness (t)
6.4mm (1/4") 8~10mm ≥10mm
9.5mm (3/8") 10~14mm ≥13mm
12.7mm (1/2") 14~16mm ≥13mm
15.9mm (5/8") 16~20mm ≥13mm

If the temperature is higher than 30°C and the humidity is higher than RH80%, the
thickness of the insulation materials should be at least 20 mm to prevent
condensation on the surface of the insulation.
