Product Name: Electrical Installation in Refrigeration 

                            Systems - Education Simulator

Model Name: YESR-E3150

Features and Description

• This device is an educational oriented device manufactured specifically

   to illustrate the different circuits and electrical devices associated

   with the refrigeration field, with this trainer the trainee can practice designing

   and executing different electrical circuits with different purposes

• The wiring of electrical components is a typical task in the field of refrigeration

• Besides the design and operation of the individual components,

   knowledge about the interaction of the components in

   circuits is an important learning objective.

   Safety aspects also play an important role

      With This product . this knowledge and these skills can be acquired

• The electrical components are arranged clearly visible

• All the components are arranged on an upright stand such that

   they are all accessible and very visible

• All components are connected on terminal blocks

• Using the cables included in the scope of delivery it is possible to set-up

   different circuits correctly and operationally

• Lamps (or other) simulate the consumers.

• All components are operated and tested with mains

   voltage to provide high relevance for practice

• There are electrical components for the start and operation of refrigerant

   compressors, such as e.g. electromagnetic start-up relay and capacitor

• With a timer, circuits can be designed and examined for cyclical

  defrosting in refrigeration systems

• This also includes the correct programming of the timer

• Typical safety components, such as pressure switches,

   thermostats and circuit breakers are also included in the scope of delivery

• These components enable the design and examination of a typical

   safety chain for refrigeration

 

Learning objectives and Experiments

• Read, understand, wire and test electric circuit diagrams

• Design, investigation and operation of electrical components from refrigeration

   (start-up capacitor, operating capacitor, start-up relay, time relay, timer,

   circuit breaker, start-up current limiter, contactors, pressure switch,

   thermostat and solenoid valve)

• Design and testing of a safety chain

• Investigate the star/delta connection

• Change of direction of rotation in an alternating current circuit

• Safety aspects when handling mains voltage
