ZM6148 Electrical Connection of Refrigeration Compressor Didactic Equipment

Technical Description
The wiring of electrical components for the start and operation of
refrigerant compressors is a typical task in the field of refrigeration.
Safety aspects also play an important role. With this knowledge
and these skills can be acquired. All components are operated and
tested with mains voltage to provide high relevance for practice.
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.
