Product Name: Refrigerator System Trainer

Model Name: YESR-5000

Technical Description

• It is able to experiment for temperature, pressure, defrosting automatic 

  control and mechanical trouble of automatic pressure control device.

• Effective to understand the constituting principle and operating principle of 

  refrigerator and freezer

• It is able to set up the temperature scope of measurement to create the P-I 

  diagram so it makes these experiments and trainings available of equipment,

  Mollier diagram, and data saving.

• Theoretical education, experiments and trainings are available for the 

  fundamental circuit and application circuit by various circuit structure of equipment

• Graphic module control has compatibility and expandability .

• Consist of transparent accessories to visualize the state, principle and flow 

 of refrigerant

• Unlike separation system in mechanical part, the control units are visualized.

• Automatic control for graphic panel with two automatic control modules

• Operating Control(ON,OFF) of monitoring and machine using data saving Function 

   and electric control board in the PC via YESR-DAQ (optional accessory)

• Fault insertion & simulation, Data acquisition and P-I diagram drawing via 

   YESR-DAQ (optional accessory)

• Manual with theory and experiments
