Product Name: Electrical Connection of Refrigerant 

                            Compressors - Education Simulator

Model Name: YESR-E3250

Features and 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 Simulator, 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 upright stand 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

 

Learning objectives and Experiments

• Read, understand, wire and test electric circuit diagrams

   for refrigerant compressors

• Design and operation of electrical components of refrigerant compressors

   (start-up capacitor, start-up relay, overheat protection, 

    automatic fuse, pressure switch, thermostat)

• Design and testing of a safety chain

• Representation methods in electrical engineering (symbols, circuit diagrams)

• Safety aspects when handling mains voltage

Instructional material

• The well-structured instructional material sets out the fundamentals

   and provides a step-by-step guide through the experiments

Technical Specification
