Refrigerant Piping
Units should be interconnected with
copper pipes.
Connection gauges of evaporating
units and remote condensing units
TRAE or TRCE, and suction and
liquid piping gauges recommended for
interconnecting both are indicated on
Table 04.
The corresponding lengths already in-
clude losses generated by valves, cur-
ves, elbows, reductions, etc.
Maximum distance (recommended)*
distance between units: 46 m .
difference in levels between units: 18 m .
(*) – Calculated distance, considering equivalent
length of connection elements.
For distances higher than the recom-
mended value, please contact Trane .
Evaporating Unit above the
Condensing Unit
- Build a 20 cm inverted siphon in the
suction line at the evaporating unit
outlet, after the regular oil accumulation
siphon.
- Horizontal sections in the suction line
should be inclined by 45 mm at every 10
m of line towards condensing unit.
Condensing Unit above the
Evaporating Unit
- Build a 10 cm siphon at rising and a
siphon at every 7.5 m of vertical line.
- Horizontal sections in the suction line
should be inclined by 45 mm at every 10
m of line towards condensing unit.
