Installation Practicals on a Split AC Trainer
Students run a suction line between the indoor and outdoor units of a split AC trainer. The pipe is cut with the Tube Cutter, cleaned up with the Reamer and turned through corners with brazed Elbow Fitting joints.
The line is then covered with Copper Pipe Insulation of the matching 10 mm or 12 mm bore, kept clear of the brazing heat. Students pressure test it with nitrogen, evacuate it and read the result on Manifold Gauges for Air Conditioning.
Frequently Asked Questions
Is 10 mm or 12 mm pipe used for the suction or liquid line?
In most split systems the larger pipe carries the cold suction gas and the smaller one carries the liquid. The right size for a given unit is set by its service valve connections, so match the pipe to the unit.
How is this pipe joined?
Copper-to-copper joints are brazed with a phosphor-copper rod, which needs no flux on copper. Joints to brass flare fittings are made by flaring the pipe end, or with a Flare To Solder Fitting brazed onto the pipe.
Does the suction line need insulation?
Yes. The suction line runs cold, so bare pipe sweats, drips and picks up heat from the surrounding air. Insulation with a 10 mm or 12 mm bore fits these pipes and cuts down both problems.
How long is each roll?
Each roll holds 15 m of pipe in one of the two sizes. Measure the run between the units first, and allow extra for bends and for cutting back a damaged end.
Why must the pipe be reamed after cutting?
A tube cutter rolls a small lip into the bore. Left in place, it disturbs the flow and can stop a flare seating or a pipe sliding fully into a fitting. A reamer takes the lip off in a few turns.
