Refrigerant Piping Guidelines

Figure 1

Refrigerant Piping

To ensure the return of oil in the
refrigerant lines, it is necessary to
follow these recommendations:

1. Select the tube lengths with care

and try to avoid having a ﬁnal few
meters of tube to use up. Refer to
table 2 for tube sizes.

2. Pitch all horizontal suction lines

down towards the unit to assist
gravity oil drainage back to the
compressor.

3. Avoid creating large oil traps in

horizontal suction lines as this will
reduce oil circulating in the system
and may eventually lead to failure
of the compressor.

4. A small oil trap at the end of a

horizontal suction line before a long
vertical riser (of more that 2.5
metres) has the advantage of
assisting the high velocity gas to
carry the oil up the vertical pipe.

5. The installation of a liquid line

sight is recommended. It is veryu
seful during the maintenance
procedures.

Refrigerant Piping Guidelines

A. Maximum recommended line

lengths: (per circuit)
Maximum linear length

200 Ft.

Maximum suction line lift

60 Ft.

Maximum liquid line lift

60 Ft.

B. Maximum allowable pressure

drops (R407C):
Suction line

6 psi.

Liquid line

35 psi.

(without subcooler)
Route refrigerant piping for
minimum linear length,
minimum number of bends and
ﬁttings (no reducers) and minimum
amount of line exposed to outdoor
ambients.

C. Recommended line sizes:
