Practicals with the Two-Zone Heat Pump

Students first run each zone on its own, then both together, in cooling and in heating. At the service ports they read high and low side pressures with Manifold Gauges for Air Conditioning, which carry an R-410A scale. A Digital Psychrometer at the return and supply air of each indoor unit gives dry bulb, wet bulb and humidity. The class then compares the wall unit with the cassette.

The louver on the outdoor unit makes a simple airflow test. Partly closing it in cooling mode starves the outdoor coil of air, and students watch the high side pressure climb. In heating mode the same restriction lowers the low side pressure. The teacher then sets electrical faults with the switches, and students trace each one with a Digital Clamp Meter and the lab manual.

Frequently Asked Questions

What does two-zone mean on a mini split?
One outdoor unit serves two indoor units, and each indoor unit heats or cools its own room or zone. Here zone 1 is a high wall unit and zone 2 a ceiling cassette, so two common indoor types can be studied on one system.

How does the heat pump switch from cooling to heating?
A reversing valve swaps the jobs of the coils. In cooling the indoor coils absorb heat as evaporators. In heating they give out heat as condensers, while the outdoor coil takes heat from the outside air.

Which refrigerant and gauges does it use?
It runs on R-410A, so use a manifold with an R-410A scale on the high and low side service ports. R-410A works at higher pressures than older refrigerants and, being a blend, is charged as a liquid.

What faults can students practise on?
Electrical faults are set with switches on the unit. Students find each one with meters, while the lab manual and instructor guide support the teacher during the exercises.

What are the expanded view sight glasses for?
They show the state of the refrigerant at key points. Students see liquid, vapour or a bubbling mix and link what they see to the pressures on the gauges in each operating mode.
