Item Description

The electrical components for the start and operation of the refrigerant compressor are arranged clearly visible. The electrical connection of the individual components is made with cables via the lab jacks. The components are e.g. the capacitor and start-up relay necessary to start the motor. The circuit diagram on the front panel enables the easy allocation of the individual components. The refrigeration circuit with compressor and receiver enables the checking of the pressure switches on the intake and delivery side of the compressor. The pressure is set via valves and the pressure switch tripped. Two manometers enable the monitoring of the pressure curve. If one of the pressure switches trips, the current supply to the compressor is interrupted. The wiring and checking of other typical components of the safety chain, e.g. circuit breaker and automatic fuse, is also carried out. The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
