9.4.2 Pipe diameter
The pipe diameter data for refrigerant lines shown below
applies as long as the following are observed:
►
A maximum of eight 90° pipe bends
►
With pipe diameters of < 35 mm, use a suitable pipe
bending tool to create the pipe bends
►
With pipe diameters of ≥ 35 mm, use type 5002 pipe
bends
►
Bending radii of ≥ 1 m are treated as straight runs
i
Information
Refrigerant lines with a pipe diameter of ≥ 35 mm
are created from rigid copper pipes in 5 m lengths.
»
With underground refrigerant lines, provide an
assembly shaft at connection sites to facilitate
soldering and maintenance work.
