The Hermetic Compressor Fault Simulator Trainer PolarX - 548 teaches the wiring, start-up, and safe operation of refrigerant compressors under mains voltage. This Hermetic Compressor Fault Simulator Trainer includes a refrigerant circuit with compressor, receiver, 2 valves, and 2 manometers to test pressure switches on the delivery and intake sides. Electrical components, including start-up capacitor, start-up relay, overheat protection, automatic fuse, and thermostat (range -30~30°C), are mounted clearly visible with lab jacks and cables for connection. Optional LABVIEW-based DAQ software supports automated data measurement.

Construction and Design
The Hermetic Compressor Fault Simulator Trainer PolarX - 548 features a control panel with test point pins, installed with simplicity on the same panel as the compressor and pressure gauges. The refrigerant circuit includes a compressor, receiver, 2 valves, and 2 manometers to investigate pressure switches on the delivery and intake sides. Electrical components for compressor start and operation are mounted clearly visible. Lab jacks and cables connect the electrical components. A circuit diagram is displayed on the front panel for easy identification of components. The unit operates on R134a refrigerant, which is CFC-free.
Software
PolarX - 548 (optional). A DAQ software package, specially designed in National Instruments LABVIEW environment, measures and calculates the results of the apparatus. The software is optional. When the software is used, a set of electronic sensors is included. The software can be run on any Windows environment.
Scope of Delivery
Q: What does the Hermetic Compressor Fault Simulator Trainer PolarX - 548 teach?
A: It teaches how to read, understand, wire, and test electric circuit diagrams for refrigerant compressors, along with safety aspects of handling mains voltage.
Q: What electrical components are covered?
A: Start-up capacitor, start-up relay, overheat protection, automatic fuse, pressure switch, and thermostat.
Q: How are pressure switches tested on this unit?
A: The refrigerant circuit includes a compressor, receiver, 2 valves, and 2 manometers, allowing pressure switches on the delivery and intake sides to be tested and monitored.
Q: What happens when a pressure switch trips?
A: The compressor's current supply is cut off.
Q: Is the DAQ software required to operate the trainer?
A: No. The PolarX - 548 software is optional, and a set of electronic sensors is included when the software is used.
