Product Name: Refrigeration Truck System Trainer

Model Name: YESR-8000

Technical Description

• Basic Experiment of Refrigeration Truck Trainer

• Low stage evaporating temperature test by changing temperature of high stage 

   condensing temperature

• Low stage evaporating temperature test by changing temperature of high stage 

   evaporating temperature

• Low stage evaporating temperature test by changing temperature air-forced 

   heat exchanger

• Testing temperature variation about cascade temperature variable

• Variation test of low stage refrigeration system by changing charging refrigerant

• Analysis temperature by controlling low stage evaporating pressure

• 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 such as cycle 

   changes of equipment, Mollier diagram, and data saving.

• 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
