Product Name: Heat Pump & Heat Accumulation 

                            Experiment Trainer

Model Name: YESR-3000

Technical Description

• It is able to experiment and train the temperature,  

   pressure-control device and auto defrosting

• It is able to experiment and educate theoretically about automatic control of 

 refrigeration system and refrigerator components.

• 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.

• Secondary heat-exchange through heat-accumulation tank.

• It is able to check and adjust the flow of the heating medium(water type)

• It is able to get the most accurate data by digital low/high pressure switch

• Heating Accumulation tank is visualized by transparent acrylic and it is able to 

  circulate the thermotherapy by circulator

• It should be structured to be able to accumulate the heat , to see the states and 

  flow of refrigerant, and to understand the principle of components to maximize 

  the achievement of education.

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

  of refrigerant

• 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
