Workshop Practice: Building a System

The class first plans a layout and lists the joints. Tubing is cut square with a Tube Cutter. Flare joints are made with the 45 Degree Flaring And Swaging Tool, which also swages a tube end to take another tube. Brazed joints are made while dry nitrogen flows through the pipe from a Nitrogen Flow Regulator Meter For Brazing, which keeps scale from forming inside.

When the circuit is complete, students pressure test it with nitrogen, check every joint and then evacuate it with one of the Small Vacuum Pumps. The teacher supervises the refrigerant charge. Students wire the thermostat and controls, start the system and take pressure and temperature readings to show that what they built works.

Frequently Asked Questions

Who is the build up trainer for?
Students who have completed basic refrigeration theory and are ready to make a system themselves. It moves them from reading circuit diagrams to cutting, joining, testing and starting a real refrigeration or air conditioning circuit.

What does the kit include?
Everything needed to make one working circuit: the main components from compressor or condensing unit to evaporator and expansion device, plus tubing, sight glasses, thermostats and controls. Workshop tools such as cutters, flaring tools and a vacuum pump are used alongside it.

Can students build an air conditioner as well as a refrigerator?
Yes. The materials make a complete operational refrigeration or A/C system. The teacher can set the task as a refrigeration circuit or an air conditioning circuit to suit the course.

In what order should a system be built?
Plan the layout, mount the main components, cut and join the tubing, then pressure test with dry nitrogen and fix any leaks. Evacuate, charge by weight under supervision and wire the controls before starting the system and taking readings.

Why flow nitrogen through the pipe while brazing?
At brazing heat, copper reacts with the air inside the tube and forms black oxide scale. A slow flow of dry nitrogen pushes the air out, so no scale forms that could later break loose and block a capillary tube or expansion valve.
